Coccidiosis is a critical disease in the poultry industry worldwide. Producers apply different strategies to control and prevent this disease. Herbal drugs are suitable remedies for reducing losses associated with coccidiosis poultry. The present study aimed evaluate effectiveness of an herbal mixture preventing coccidiosis. A total 160 broiler chickens were divided into four treatment groups, ...

Background: Soil structure is mainly composed of sand, silt, clay, and organic materials. Organisms can live in the soil. The large number of stray cats in the cities of Iran is a major environmental and health problem. Toxoplasma oocysts are shed with the feces of cats, so soil is known as a potential source of transmission of toxoplasmosis. The aim of this study was to determine the soil cont...

To determine the minimum number of Cryptosporidium oocysts that can be detected in stool specimens by diagnostic procedures, stool samples seeded with known numbers of Cryptosporidium parvum oocysts were processed by the modified Formalin-ethyl acetate (FEA) stool concentration method. FEA concentrates were subsequently examined by both the modified cold Kinyoun acid-fast (AF) staining and fluo...

  Humoral immune response of vaccine-I (supermatent from sonicated sporulated oocyst), vaccine –II (sediment from sonicated sporulated oocyst) and vaccine –III (un-sonicated sporulated oocyst) against conccidiosis in chickens was determined by indirect haemagglutination (IHA) test. IHA antibody titre was significantly higher (p

purpose: the purpose of this study is to model cryptosporidiosis in laboratory animals. the parasites were inoculated into animalsand thenmultiplied. the process of proliferation was compared to controlcryptosporidiosis in humans. materials and methods: twenty-five laboratory mice (4-7 days of age) and twenty-five laboratory rats (5 days of age) were assigned to the category i while the categor...

Eight concentration and purification methods were evaluated to determine percentages of recovery of Cryptosporidium parvum oocysts from calf feces. The NaCl flotation method generally resulted in the highest percentages of recovery. Based on the percentages of recovery, the amounts of fecal debris in the final oocyst preparations, the relatively short processing time (<3 h), and the low expense...

Understanding the environmental pathways of Cryptosporidium is essential for effective management of human and animal cryptosporidiosis. In this paper we aim to quantify livestock Cryptosporidium spp. loads to land on a global scale using spatially explicit process-based modeling, and to explore the effect of manure storage and treatment on oocyst loads using scenario analysis. Our model GloWPa...
