Waterborne outbreaks of Toxoplasma gondii have focused attention on the importance of oocysts shed in the feces of infected cats. Cat feces deposited annually into the environment in the United States total approximately 1.2 million metric tons. The annual oocyst burden measured in community surveys is 3 to 434 oocysts per square foot and is greater in areas where cats selectively defecate. Bec...

McMaster (McM) method is one of the most widely used techniques for assessment faecal parasites shedding in veterinary practices because its simplicity. However, due to light sensitivity, recently, Mini-FLOTAC (MF) has been introduced as a possible alternative worm egg counts. This study aims compare diagnosis performance MF McM technique. Faecal samples from 40 animals randomly selected sheep,...

forty-one wild sheep (ovis ammon orintalis) from kabodan island of national park of urmialake (north-west of iran), were examined during a period of six months from october 2002 tomarch 2003, for helminthes and coccidian infection. the numbers of oocyst and eggs per gram offaeces (opg & epg) were determined by the centrifuge flotation technique using saturated sugarsolution. the rate of inf...

to compare the effect of coccidiostate drugs (salinomycin and maduramicin) on the oocyst sheding and performance of coccidi-infected broiler chicken, 180 ross 308 broiler chicken were randomly assigned to four treatments. each treatment contains 3 replacements of 15 chickens. treatment 1 and 2 fed diets supplemented with maduramicin and salinomycin until three days before experiment period, res...

The relationship between oocyst dose and lesion score was evaluated in trials involving five field isolates each of Eimeria acervulina, Eimeria maxima, and Eimeria tenella. Each trial included an uninfected, unmedicated treatment, and at least three treatments of unmedicated birds given different doses of oocysts from a single isolate. In four trials each with E. acervulina and E. tenella, and ...

the poultry industry has been outbreak with an intricate problem called coccidiosis from the beginning and undoubted coccidiosis is one of the most widespread poultry diseases especially among breeder herds and ancestor. so the interest in alternative methods for the control of coccidiosis has been dramatically increased in recent years, and it is necessary to look for methods which are adaptab...

During June 1996, water supplies of the city of San Pedro Sula, Honduras, were sampled to obtain an assessment of Cryptosporidium oocyst and Giardia cyst concentrations. Each sample was concentrated and stained with an indirect immunofluorescent antibody, and parasites were counted through microscopic analysis. In three surface water supplies, Cryptosporidium oocyst concentrations ranged from 5...

The aim of the present study was to investigate the efficacy of monensin sodium grain size on controlling coccidiosis in broiler chickens. Three hundred and fifty Cobb 700 chicks were infected experimentally with 8 × 10(4) sporulated oocysts of Eimeria spp. The birds were fed with diets supplemented with powdered (n = 150) or granulated (n = 150) monensin, with particle sizes of ≤ 100 µm and 45...

Response of Nigerian indigenous (local) and broiler chickens to experimental Eimeria infections was investigated by measures of clinical signs, packed cell volume (PCV), body weights (BW), feed consumption, faecal oocyst counts (oocyst per gram), and microscopic intestinal lesions. Three-week-old chickens of each breed received single pulse infections with 2500, 5000, and 100.000 sporulated Eim...

The viability and infectivity of Cryptosporidium parvum (C. parvum) oocysts, detected in water samples collected from river water in Hokkaido, were investigated using Severe Combined Immunodeficient (SCID) mice. The water samples collected from September 27 through October 10, 2001 by filtration using Cuno cartridge filters were purified and concentrated by the discontinuous centrifugal flotati...
