[0001 ] FIELD OF THE INVENTION

[0002] The present invention is directed to Anti-Apicomplexan compositions, methods of preparing the same and methods of administering the same to animals, for example poultry, for preventing and treating infection and disease.

[0003] BACKGROUND OF THE INVENTION

[0004] Apicomplexa protozoa, in particular, Eimeriorina and Cryptosporidiidae , are parasitic to livestock. Cryptosporidia spp. include 30 named species and cause intestinal infections in vertebrates, including Man. Coccidiosis is a widespread disease characterized by diarrhea, emaciation, impaired feed intake, as well as lack of feed efficiency and growth and even mortality in a wide array of organisms, ranging from poultry to ruminants and lagomorphs. Coccidiosis is known to be caused by the Apicomplexan parasite Eimeria spp. The life cycle of Eimeria spp. involves only one host, but encompasses two major stages. The first stage includes a free oocyst, the source of which may be animal feces. The free oocyst thrives particularly in litter in the premises of animals and is known to sporulate under suitable temperature and humidity conditions. The second stage includes a sequence of developmental, a-sexual and sexual stages, which thrive in the epithelia of host gastro-intestinal tract and are eventually defecated in the form of unsporulated oocysts.

[0005] Poultry is known to be affected by seven different species of Eimeria. The Eimeria tenella species, involved in the coccidiosis of broiler chicks from week 1 to week 8, causing, e.g., caecum lesions, is known to be one of the most harmful species. Further, the E. necatrix species, known to affect chicks from weeks 5-7, by, e.g., causing lesions in the medial jejunum and the caeca, is also considered to be highly harmful. In addition, for example, the i . acervulina species affects young layers and features lesions in the duodenum and proximal jejunum. In infected surroundings, such as poultry enclosures, the parasite may be present on the floor in the form of oocysts that are ingested by chicks. Oocysts are highly resilient to adverse conditions and therefore are extremely difficult to treat. Oocysts become infective once sporulated, a process that requires 25-30°C and oxygen for 2-4 days, which is a condition met in all poultry enclosures used in the industry since the poultry itself requires such conditions.

[0006] Generally, coccidiosis is treated by vaccination as well as by administering coccidiostats, i.e., substances that control the proliferation of Eimeria spp. Each coccidiostat is known to impair a certain metabolic cycle in the parasite, for example, ethopabate and sulphonamides/amprolium impair the metabolism of folic acid and thiamin, respectively; and decoquinate may impair mitochondrial activity. Coccidiostats may be Eimeria species-specific and therefore, ethopabate and sulphonamide may be used to specifically combat E. acervulina E. maxima , and E. brunetti. Some coccidiostats may be stage-specific, for example, amprolium may affect the first schizont generation, sulphonamide may affect the second schizont stage and clazuril, diclazuril, totrazuril may affect all developmental stages.

[0007] Despite the importance of the various types of coccidiostats, residues thereof may remain in poultry products, including meat and eggs, which may be harmful to humans, due to cross-reactivity with human microbiome. Therefore, the use of coccidiostats is performed in the industry under tight regulations. For example, since 2006, European Council (EC) regulations allow the use of coccidiostats only for treating known infections, not as a preventative treatment. Further, the status of coccidiostats treatments is gradually changing from a food supplement to a drug. Total and final banning of coccidiostats is intended to be implemented in 2021 (Article 11 of EC Regulation 1831/2003). Such regulations are expected to be raised in many additional jurisdictions world-wide.

[0008] Accordingly, a“green”, “non-chemical” and non-hazardous feed supplement for controlling Eimeria infection is highly desirable. Particularly desirable would be a feed supplement that impairs the sporulation of the Eimeria species, since such a supplement would prevent the initial infection and therefore, may be highly efficient.

[0009] On 2017, the European Union registered an olive extract produced from Olea europaea as a botanically defined, natural product in the European Union Register of Feed Additives. On 2019, GMP+ International listed several olive-based products (olive acid oils, olive husks, olive meal, olive pulp) as GMP+ approved feed materials. Olive-related products are thus safe for animal consumption.

[0010] SUMMARY OF THE INVENTION

[0011] The present invention provides Anti-Apicomplexan compositions, as well as methods for producing such compositions and methods for using such compositions.

[0012] The present invention is base, in part, on the surprising finding that olive mill waste, produced in high quantities during the process of producing edible olive oil from olives, may be manipulated to provide natural extracts with a potent Anti-Apicomplexan activity. The provision of compositions according to the present invention is beneficial for many reasons. For example, the methods provided here to produce beneficial compositions make use and recycle the liquid phase of olive mill, an environmentally-unfriendly and polluting material because of its high load of organic acids, acidic pH and deleterious effects on the aerobic bacteria used to detoxify wastewater in purification plants. In addition, the compositions according to the present invention may be entirely natural olive-derived-extracts, which are safe for animal growth and propagation. This advantage is of special interest as the animals, and/or their products, may be ultimately consumed by other animals, such as humans, thus preventing any risk of toxicity. Such advantages are particularly relevant in the field of commercial animal breeding and handling, as anti-coccidiosis competitors are banned from growing markets. For example, the EU has already banned antibiotics used in human medicine from being routinely added to animal feed. New Regulation completes this ban on antibiotic growth promoters in feed by prohibiting the use of the coccidiostats monensin sodium, salinomycin sodium, and avilamycin.

[0013] More, compositions according to the present invention are soluble and readily diluted in water, which makes their use highly convenient.

[0059] Commercial production of olive oil, known for its wide-spread culinary and cosmetic use, is accompanied by the production of liquid olive mill waste. Liquid olive mill waste is considered as an environmentally-unfriendly and polluting material, since it contains high concentrations of organic acids and has an acidic pH. Such material has deleterious effects on the environment, for example on aerobic bacteria used to detoxify wastewater in purification plants.

[0060] The present invention is based in part on the finding that instead of the continued dumping of untreated liquid olive mill waste to the environment, olive mill can be manipulated to provide a beneficial and“green” product for commercial use. According to the present invention, such use is highly versatile, as the compositions of the invention, produced e.g. from liquid olive mill waste, have been found effective in several aspects. Firstly, compositions of the invention have been found to have anti-sporulation and anti-coccidiosis activities, as exemplified herein. Without being bound to any theory or mechanism, the anti-coccidiosis activity may be linked to another beneficial effect of the compositions of the invention, being the ability to deform, seal, perforate or rupture biological membranes, as also exemplified herein. In addition, despite origination, in certain embodiments, from toxic material, the compositions of the invention have been found to be safe to animals. Therefore, the compositions of the invention are highly beneficial in a variety of commercial and agricultural aspects, and even more so considering they may be produced from toxic commercial waste products.

EXAMPLES

Example 1. Preparation of an olive waste extract.

[00172] Olive are harvested and conveyed to the olive mill, crushed, added water, and decantation and centrifugation are used to separate the three phases: solid, olive mill with water and oil. The olive mill plus water is considered olive waste and used to produce the“Antisolv extract” or the“Antisolv extract composition” of the invention. One liter of olive waste stored at 4°C, was centrifuged (8000g) for 10 minutes, and then the liquid phase was subjected to filtration using a 75 pm sieve. Then, the liquid phase was centrifuged and an additional amount of 250ml of 100% ethanol was added. Then the liquid was concentrated under high vacuum (starting 1000 mbar till 80 mbar) using a rotor-evaporator at 40°C until it reached a volume of 250ml, in order to remove the ethanol. Then, in order to remove the water, the same procedure is used under a pressure of 50 mbars. The process of evaporation and addition of 100% ethanol was repeated until no more solid (which is a cellulosic mixture) precipitated from the liquid phase. The liquid phase, which mainly contains a polyphenolic/flavonoid mixture, was evaporated under high vacuum to produce 40 grams of a dark-brown paste, referred to herein as“AntiSolv extract”,“Antosolv”,“olive waste extract” or“extract”, interchangeably. A diagram presenting an embodiment of the extraction process of the invention is presented in Figure 1.

[00173] Figure 2 presents an HPLC diagram of a sample of the extract. Dry sample of the extract was dissolved in 100% methanol or 1 :1 (v:v) ethanol 100% and isonitrile, then injected into the HPLC for analysis. Peaks #1-2 represent hydroxytyrosol (including derivatives), peak #3 represents 3,4 dihydroxyphenylacetic acid, peaks #4-5 represent tyrosol (including derivatives), peak #6 represents caffeic acid, peak #7 represents p-coumaric acid, peak #8 represents ferulic acid, and peak #9 represents oleuropein (Table 1).

[00174] It is noted that a Folin reaction (the reaction of amino acids in alkaline solution with l,2-naphthoquinone-4-sulfonate (Folin reagent) was used to test the phenolic content of the obtained extract. It is estimated that the phenolics contained in Antisolv are the active agents involved in the inhibition of sporulation, as they bond with proteins in membranes, impairing permeability. The concentration of the main compounds in the obtained extract, as detailed in Figure 2, are presented in Table 1 below:

[00175] Table 1. Polyphenol concentrations in a sample of Antisolv extract (61.8 ppm in total).

*Area under the curve (arbitrary units).

Example 2. Efficacy of an olive waste extract in-vitro.

[00176] Eimeria- infected feces were collected from goats and stored at 4°C. Later, 3 grams of feces were mixed with 42 ml of tap water. The sample was homogenized and passed through a mesh, after which the filtered liquid was collected into 50 ml tubes. The liquid was then washed three times with cold tap water and centrifuged (1,700G, 5 minutes, 20°C). In each wash, the supernatant was carefully removed and approximately 30 to 40 ml of cold water was added. After the last wash, the water was removed and replaced with saturated sugar flotation solution (500gr sucrose in 320 ml double distilled water), wherein each tube was filled with up to 45 ml of the sugar flotation solution. Each tube was centrifuged twice, wherein after each round of centrifugation, the ring-shaped phase formed on the top of the sugar solution was collected (about l-2ml collected after each round) and preserved in a 50 ml plastic tube.

[00177] The plastic tube was filled with cold water and centrifuged again. Oocysts were found in the sediment after centrifugation. The water was gently removed and the concentration of the oocysts was evaluated. The oocysts were then stored at 4°C until use (the use of unsporulated oocysts that are older than two weeks was avoided). It is noted that a 2% potassium dichromate solution may be used for conservation. The unsporulated oocytes were washed in cold phosphate buffered saline (PBS, X10) before use in order to remove potassium dichromate (if used). The concentration of the oocysts was adjusted to approximately 30,000/ml.

[00178] Extract was prepared according to Example 1 above. Extract can be mixed with Phosphate buffer saline (PBS, XI, w:w, 1 : 10) if not perfectly soluble in water.

[00179] 1 ml of Antisolv extract at concentrations of 500, 1000, 2000, and 4,000 ppm together with 1 ml of the oocysts solution were placed in 5 ml glass tubes, wherein each glass tube was covered with Parafilm®, with holes to allow for oxygen supply and vortexed at 150 rpm. Each assay was in triplicates for each concentration of extract and gallic acid purchased at Sigma. In addition, six concentrations of gallic acid (50, 150, 250, 350, 450, 550 ppm) were added to 2000 and 4000 ppm of the invention extract to check synergism of gallic acid and the extract on impairment of sporulation. The glass tubes were covered, with holes for air, stored at room temperature (26-28°C) for 48 hours on a rotator. Control glass tubes (3 per assay), filled with 1 ml of oocyst solution and 1 ml DDEbO (doubly-distilled water) or PBS (Phosphate buffered saline) without extract was prepared.

[00180] After incubation, the tubes were washed with PBS and kept at 4°C until counting the oocysts. The assay was repeated for six replications (six concentrations, five droplets each, each having at least 100 oocysts per droplet, 30 samples in total) and sporulation percentage was averaged within extract concentration. Sporulation was identified by microscopy, as shown in Figure 3, and sporulation rate was calculated.

[00181] There was no impairment of sporulation in the controls (containing water only), compared, for example to 50 ppm of gallic, caffeic, and vanillic acid (Figure 4), which are produced during the degradation of polyphenols in the intestine, or the extract of the invention (Figure 5A-5C). Gallic acid was selected because it is an accepted and well-regulated nutrition supplement for poultry. [00182] Speculation was impaired by the extract of the invention in a dose-dependent fashion (Figure 5A), reaching 60% inhibition of sporulation at the maximal concentration of 4,000 ppm of Antisolv extract, encompassing all its components.

[00183] Gallic acid increased the impairment of sporulation when given as supplement to the extract of the invention: as presented in Figure 5B, the addition of gallic acid to 2000 ppm extract reduced the sporulation percentage of the oocysts to about 30%. As presented in Figure 5C, the addition of gallic acid to 4000 ppm extract reduced the sporulation percentage of the oocysts to about 20%.

Example 3. Efficacy and safety of an olive waste extract in-vivo.

[00184] Chicks aged 2-4 weeks were allowed ad-libitum drinking strictly from water containing 0.5% (5000 ppm) of Antisolv extract of the invention. It was found that these chicks could thrive well, and their growth was not affected, compared to chicks drinking untreated tap water.

Example 4. Efficacy of an olive waste extract in-vivo.

[00185] A dose-response experiment was conducted: treatments are 0, 2000, 4000, and 8000 ppm of extract with/without 400 ppm gallic acid. Chicks are uninfected or infected with 50,000- 100,000 oocysts of mixed Eimeria (Table 2).

[00186] Five replicates of 20 chicks for treatment (800 chicks). Water and feed intake weekly, feed efficiency throughout; morbidity, opg (oocyst count per gram droppings), mortality - are all monitored. Liver and intestine morphology (location and severity of lesions) are examined in ten chicks/treatment. Feed intake and growth performance are recorded, stats by two-way ANOVA, repeated measurements. Water fluidity and pH, weekly; tube-clogging events are monitored.

Example 5. Efficacy of an olive waste extract in-vivo.

[00187] 160 chicks allotted to 8 treatments, encompassing two groups of uninfected birds and six groups of Eimeria- infected birds, were tested. Birds were administered water treatment from 7 days of age and infected when 10-days old.

[00188] Inoculation was individually, per os, by using a dose of Paracox 5, a live attenuated anticoccidial vaccine including administered at the twenty -fold the recommended dose (Table 2), in a volume of 1 ml, when chicks were 10 days old. Uninfected birds were given the same volume of saline. Eimeria spp were as in Table 2.

[00189] Table 2. The composition of inoculated Eimeria spp.

[00190] Water was supplied in 3-liter poultry troughs that were re-filled when needed. Tap water was initially given and water supplementation was initiated three days after chicks’ arrival. Water treatments for the uninfected (C) birds were no antisolvent and no gallic acid (C_AS0%_GA0) and 1% antisolvent with 500 ppm of gallic acid (C_AS1%_GA500).

[00191] Water treatments for the infected (T) birds were bi-factorial with 3 levels of antisolvent (AS; 0, 0.5, and 1%) and two levels of gallic acid (GA; 0 and 500 ppm) resulting in 6 groups: T_AS0%_GA0, T_ AS0.5%_GA0, T_AS1% _GA0, T_AS0.5%_GA0, T_

AS0.5%_GA500, and T_AS1% _GA500.

[00192] Birds were wing-tagged and weighed on infection day and then, 7 days after infection. Half of the birds were weighed and humanely euthanized by exposure to CO2 on day 14 after infection and the second half on day 17 after infection. Water intake was recorded. Droppings were collected from a lm ² paper sheet placed in each group 12 h before each weighing and kept at 4°C until oocysts were counted under a grated microscope at xlOO and x 400 at days 0, and 7.

[00193] Liver was inspected and spleen was inspected and all parts of the gastro-intestinal tract, encompassing the duodenum, ileum-jejunum, and caeca were noted for lesions in a 0-4 scale. No existing method, based on mono-species Eimeria infection, was satisfactory. The duodenum was examined at three sites (proximal, medial, distal) and a separate score was recorded for each. In contrast, only one score was recorded for the ileum-jejunum, and one for the caeca. Organ scores were termed D (average of 3 sites along the duodenum), J, and C. Three composite scores were established: a. sum of the average duodenal score, the jejunal score and the caecal score; b. sum of the maximal duodenal, jejunal and caecal scores; c. number of lesion- affected organs (1-3).

[00194] Data for body weight (BW) and average daily gain was log-transformed in order to homogenize variances. The C_AS0%_GA0 and C_AS0%_GA0 were compared in order to assess the effect of infection. The C_AS0%_GA0 and the C_AS1%_GA500 were compared to evaluate possible toxicity due to water treatment. All groups encompassing bi-factorial levels of AS and GA were compared by bi-factorial ANOVA.

[00195] For the analysis of lesions, for each treatment and slaughter day, the Wilcoxon Rank Sum Test was run. Then, using the Iman-Connover method, a rank transformation was done on original data and a two-way ANOVA was run on the ranked data. The treatment x day interaction was significant for J. Sum DJC, and #organs affected and Pairwise comparisons were made by Tukey test.

[00196] Results.

[00197] A total of 6 chicks died throughout experiment, independent of treatment, two of them after inoculation, including one in the C_AS0%_GA0 uninfected group.

[00198] Water intake was little affected, if any, by water supplements (Table 3). No signs of toxicity whatsoever were apparent in chicks drinking AS and/or GA-supplemented water.

[00199] Table 3. Water intake in uninfected chicks given no water supplement (C_AS0%_GA0) or water with 1% antisolvent and 500 ppm gallic acid (C_AS1%_GA500), or infected and given water with bi-factorial combinations of antisolvent (AS, 0, 0.5%, and 1%, corresponding to 0 ppm, 5,000 ppm, and 10,000 ppm, respectively) and gallic acid (0 and 500 ppm).

[00200] Unvaccinated medicated control birds substantially did not excrete oocysts for 14 days after infection, indicating freedom from both between-pen contamination by the vaccine and invasion of the chicken-house by extraneous coccidial infection (Table 4). Birds treated with combinations of antisolvent and gallic acid had very low excretion of oocysts, much lower than counterparts given plain water (5,200-14,200 in treated-infected, compared with 96,000 in non- treated-infected birds). However, non-treated fowls (T_AS0%_GA0) did not excrete oocysts at day 14, probably because of higher immune response.

[00201] Table 4. Oocyst counts in droppings (gr ¹ ), days are relative to infection day.

[00202] Infection resulted in significantly lower body weight from d 7 throughout experiment (Table 5).

[00203] Table 5. Body weight of chicks throughout experiment, days are relative to infection day (Means ± SE).

* Column-wise, different uppercase letters denote statistically significant differences between C_AS0%_GA0 and T_AS0%_GA0, i.e., effect of infection. ** Column-wise, within T groups, values with same lowercase letters do not differ statistically. *** Column-wise, P is for the comparison of water treatments within infected chicks.

[00204] The effect of infection on average daily gain (ADG, Table 6) was particularly deleterious on days 0-7 (P<0.001), in which, group-wise, when log (opg) was plotted against BW gain for the first 7 d after infection, a significant negative effect was shown (Figure 6). The BW of uninfected, untreated birds and infected birds given the AS0.5% GAO treatment was identical throughout. In other words, drinking water with AS0.5% (5,000 ppm Antisolve) annihilated the effect of infection on growth performance.

[00205] Table 6. Average daily gain (g d ¹ ) of chicks throughout experiment.

[00206] The performance growth of infected birds with no water treatment (T_AS0%_GA0) or with the maximal treatment (T_AS1%_GA500) was inferior, compared to all other treatments. There was no advantage in adding gallic acid if an AS treatment was given. Providing infected birds with AS0.5%_GA0 was the best treatment but that treatment did not result in statistically higher BW, compared with T_AS0%_GA500, T_AS0.5%_GA0, T_AS0.5%_GA500,

T_AS1%_GA0 at the end of experiment. For average daily gains within infected birds (Table 6), water treatments ranked AS0.5>AS1=AS0, AS0.5>AS1=AS0, AS0>AS0.5=AS1 for days 0-7, 8- 14, 14-17, respectively. Only for the three last days, antisolvent supplementation had no effect on growth performance.

[00207] Overall, data shows that infection with Eimeria impaired growth, providing water with 0.5% AS helped alleviating the effect of infection, GA was not needed if AS was provided and the combination of AS1% and GA500 was deleterious to growth performance. [00208] No events of liver lesions, enlargement or discoloration were found. Some birds presented an enlarged or whitish spleen, without relation to infection or treatments. However, non-infected birds in the C_AS0%_GA0 had the least frequency of bloody spleen.

[00209] The infection was effective, as evidenced by lesions along the GIT (Figure 7). Overall, more lesions were found on day 17 than on day 14. The non-infected C_AS0%_GA0 birds had no lesions on day 14 and a very milk infection on day 17 and it was the least-affected group throughout. No lesions were found in this group on day 14 after infection but the number of lesion-afflicted birds increased from day 14 to 17 (Figure 8), evidence of oocyst recycling from infected to non-infected birds during the removal of fowls on d 14. Lesions were noted more frequently in the duodenum and jejunum, both in the serosa and mucosa, than in caeca. Failure to detect lesions in T_AS1%_GA500 birds is challenged by the oocysts count in their droppings on day 7 post-infection. For both the sum of lesions and number of organs affected, the groups ranked C_AS0%_GA0< C_AS1%_GA500= T_AS0.5%_GA500, the rest of groups showing intermediate values.

[00210] The results above demonstrate that (a) providing broilers with a water-dispersible AS that inhibits sporulation, with or without gallic acid, would attenuate coccidiosis damages in poultry; (b) AS in water did not affect water consumption; (c) infection was effective, as monitored by opg in droppings, and impaired growth, albeit lesion scores were low; and (d) providing water with 0.5% AS cancelled the deleterious effect of Eimeria infection on growth. Gallic acid was not needed if AS was provided and the combination of AS1% and GA500 was even deleterious to growth performance.
