“…Yim et al [38] also reported that A. vera extract can be used as a safe dietary supplement against coccidiosis. Some other studies had also reported the similar findings in broilers and rabbits [39][40][41] . Lesion score is the most common method for assessing intestinal condition during coccidiosis [42] .…”

This study reports the immunotherapeutic effects of Aloe (A.) vera polysaccharides against coccidiosis in broiler chicken. For the purpose, polysaccharides were recovered from A. vera and analyzed by using HPLC. Three different hexose sugars including maltose, glucose and mannose were detected in hydrolyzed solution of A. vera. The extracted polysaccharides (graded doses) were evaluated for immunotherapeutic activities against coccidiosis in chicken. Results revealed that percent protection and daily weight gains were significantly higher (P<0.05) in chicken administered with A. vera polysaccharides as compared to control group. On the other hand, oocyst counts and lesion scores were lower (P<0.05) in polysaccharides administered chickens as compared to control. Moreover, anti-coccidial indices were also higher in chickens administered with polysaccharides (159.75-239.63) as compared to control (36.57). Except spleen, the organ-body weight ratios of all lymphoid organs of experimental and control groups were statistically similar (P>0.05). Based upon findings of this study, it was concluded that A. vera derived polysaccharides had immunotherapeutic activity against coccidiosis in chickens and might be further explored for its commercial feasibility for effective use in poultry industry to control avian coccidiosis.

This experiment was conducted to investigate if usnic acid, a lichen metabolite, exerts therapeutic action against coccidiosis. A total of 160 one-day-old male Ross 308 broiler chicks were divided into 5 experimental groups (A-E), each replicated in 4 pens of 8 chicks. At 16 days of age Groups B-E were infected orally with a mixture of purified oocysts including 30 x 10 4 sporulated oocysts from field isolates of E. acervulina, E. brunetti, E. maxima, E. mitis, E. praecox and E. tenella, whereas Group A was remained uninfected. Seven days after the coccidiosis induction, infected birds were divided into 4 groups to receive orally with 20 mg usnic acid (Group C), 100 mg usnic acid (Group D) and 7 mg toltrazuril (Group E) per kg body weight. The birds in Group B were untreated and served as infected control. The experiment was terminated at 29 days of age. As a result of the study it was evaluated that infected birds had lower feed intake and body weight and worse feed conversion, higher intestinal lesion score, longer small intestine and cecum, and higher fecal oocyst count than healthy birds. The anticoccidial effect of usnic acid at 100 mg/kg application dose was comparable to toltrazuril as reflected by alleviations in performance and pathology findings. In conclusion, it is demonstrated that usnic acid possesses some anticoccidial effects, but not nearly as good as toltrazuril. Keywords: Lichen, Usnic acid, Toltrazuril, Broiler, Coccidiosis Usnik Asitin Broylerlerdeki Anticoccidial Etkinliği ÖzetBu çalışmada, bir liken metaboliti olan usnik asitin coccidiosise karşı terapötik etkinliğinin araştırılması amaçlanmıştır. Toplam 160 adet, 1 günlük yaştaki erkek Ross 308 civciv, her bir grup 4 tekerrürlü olacak şekilde 5 deneysel gruba (A-E) ayrılmıştır. Hayvanlar 16 günlük yaşa geldiğinde Grup B-E'dekiler E. acervulina, E. brunetti, E. maxima, E. mitis, E. praecox ve E. tenella'nın saha izolatlarından elde edilmiş inokulumdan 30 x 10 4 sporlanmış oocyst ile enfekte edilmiştir. Grup A'da yer alanlar civcivler ise enfekte edilmeden kontrol olarak bırakılmıştır. Hastalık oluşturulduktan 7 gün sonra, enfekte hayvanlara ağız yolu ile 20 mg/kg usnik asit (Grup C), 100 mg/kg usnik asit (Grup D) ve 7 mg/kg toltrazuril (Grup E) uygulanmış; B grubundaki enfekte hayvanlara tedavi uygulanmadan enfekte kontrol olarak bırakılmıştır. Broylerler 29 günlük olduğunda çalışma sona erdirilmiştir. Enfekte hayvanların sağlıklı hayvanlara kıyasla daha düşük yem tüketimi, vücut ağırlığı ve yemden yararlanma oranına; daha yüksek lezyon skoruna, daha uzun bağırsak uzunluğuna ve daha yüksek oocyst sayısına sahip olduğu tespit edilmiştir. Performans ve patolojik bulgulardaki değişimler göz önünde bulundurulduğunda 100 mg/kg dozda uygulanan usnik asitin toltrazuril ile karşılaştırılabilecek derecede anticoccidal etkinliğe sahip olduğu belirlenmiştir. Sonuç olarak; usnik asitin bazı anticoccidial etkinliklere sahip olduğu ancak bu etkilerin toltrazuril kadar güçlü olmadığı kanısına varılmıştır.

In this study, 4 different extracts of Thymus praecox subsp. grossheimii var. grossheimii (Ronniger) an endemic species of genus Thymus were investigated on gram positive and gram negative test bacteria for the antibacterial activity. The plant extracts were obtained via Soxhlet method, and the antibacterial activities were determined by macrodilution liquid (tube) method (MIC). Results indicated that 4 different extracts at different concentrations showed antibacterial activities on both gram positive and gram negative strains. The highest antibacterial activity was observed in acetone extract against Bacillus cereus, whereas the lowest activity was seen in methanol extract against Klebsiella pneumonia, Proteus mirabilis, Pseudomonas aeruginosa and Salmonella Enteritidis. In conclusion, it was determined that Thymus praecox subsp. grossheimii var. grossheimii (Ronniger) has an antibacterial activity against gram positive and gram negative test bacteria.
