Escherichia coli O157 and Salmonella spp. are among the leading causes of food-borne illness in the United Sates and bacteria have been isolated from numerous ruminant animal sources. The objective of this study was to assess the incidence of E. coli O157 and Salmonella spp. in white-tailed deer (Odocoileus virginianus) and livestock simultaneously grazing the same rangeland. Escherichia coli O...

Pasteurella multocida is a gram-negative, opportunistic pathogen and the common inhabitant of the upper respiratory tract of domesticated and wild animal species. It is a causative agent of numerous economically important diseases worldwide, such as enzootic bronchopneumonia in ruminants and haemorrhagic septicemia in cattle and buffalo. The present study was undertaken to determine the prevale...

Ewe abortion and neonatal mortality are serious problems to sheep farmer. The objective of this paper was to report isolation of Erysipelothrix rhusiopathiae from aborted fetuses in a flock in Tehran, Iran. Abortion occurred in 10% of ewes in the flock. The fetuses were well developed and pinpoint, necrotic-like lesions were recorded on the placental cotyledons, whilst the inter -cotyledonary a...

prions are unprecedented infectious pathogens that cause a group of invariably fatal neurodegenerative disease by an entirely novel mechanism. the conformational change in prion proteins results in a change from a predominantly α-helical protein to a β-sheet form, which causes scrapie in sheep and goat. the present study was carried out to identify polymorphisms of the prion protein gene (prp) ...

b a ckground: anaplasmosis is an important issue for animal breeders in terms of economic losses as well as a health concern to human. ticks are considered as the main vector of this disease. lack of documented information about anap lasma species in iran was the scope of this study to determine the population of ticks and the presence of anap lasma in ticks, domestic ruminants and also human b...

BACKGROUND Some techniques of transvaginal ovarian drilling have been previously described. Nevertheless a monopolar transvaginal ovarian cauterization, that use the expertise and safety of transvaginal puncture for oocyte captation seems to be an easier and feasible approach. The aim of this study was to develop a minimally invasive ovarian cauterization technique under transvaginal ultrasound...

I T was recently shown that alkaline phosphatase of sheep serum occurs in three molecular forms, A, B and C, with descending rate of migration in starch gel electrophoresis ( R E N D ~ L and STORMONT 1964). The phosphatase variation is closely related to the blood groups within the R-0-i system. B phosphatase is almost invariably found in animals of blood group 0, while animals of blood group R...

Cystic echinococcosis, caused by Echinococcus granulosus, is an emerging disease in many parts of the world and, in particular, in eastern Europe and the former Soviet Union. This paper examines the abundance and prevalence of infection of E. granulosus in cattle and sheep in Kazakhstan. Observed data are fitted to a mathematical model in order to determine if the parasite population is partly ...

MAŠKOVÁ E., PAULÍČKOVÁ I. (2006): PCR-based detection of cow’s milk in goat and sheep cheeses marketed in the Czech Republic. Czech J. Food Sci., 24: 127–132. A method based on the polymerase chain reaction (PCR) principle was validated for detecting cow’s milk in goat and sheep cheeses. DNA was isolated from the cheeses using the isolation kit Invisorb Spin Food I by Invitek Co., designed for ...
