Neospora caninum is a protozoan parasite causing bovine abortion all over the world. The aim of this study was to investigate how common N. caninum infection is among dairy herds in the Czech Republic. Bulk milk samples were collected from 495 dairy herds and analysed for the presence of specific antibodies by a commercial N. caninum iscom ELISA. Five out of 495 dairy herds (1.01%) had percenta...

Objectives were to estimate percentages of seropositive herds with cows shedding Mycobacterium paratuberculosis in feces and milk, and to estimate sensitivity, specificity, and predictive value of an ELISA relative to fecal culture. Dairy cows (n = 712) were randomly selected from 61 herds previously identified by ELISA as positive for Johne's disease. Fecal and bulk tank milk samples (n = 52 o...

Forty-three individual human milk samples obtained 2 weeks to 17 months postpartum were divided into five large pools. Theseplus three large individual human milk samples obtained 2 and 5 months postpartum were tested for antiviral activity against Japanese B encephalitis virus, Friend leukemia virus, and Rauscher leukemia virus. All milk samples had a high degree of antiviral activity against ...

A series of experiments were performed to evaluate the performance of experimental detergents. Initial assessment of cleaning efficacy was done using a standardized milk soil (whole milk inoculated with bacteria) sprayed onto stainless steel test chips and allowed to incubate. These test chips were cleaned under controlled conditions in the laboratory. The residual milk soil was assessed using ...

: Bulk tank milk samples, collected from 347 herds throughout the Republic of Ireland using a sampling frame based on seven milk-recording organisations, were tested by ELISA for antibodies to Leptospira interrogans serovar hardjo. These herds, which had not been vaccinated against leptospirosis within the previous five years, were categorised according to their province, milk-recording organis...

Milk is a bulky product, expensive to transport, and very susceptible to contamination, which in a short time renders it unpalatable. In its natural state it contains al^out 87 per cent of water, which is a comparatively worthless constituent. ' Efforts to reduce the water content of milk, leaving the solids in ; a more concentrated form without destroying their food value, and at the same time...

listeria monocytogenes as one of the most important pathogen in public health concerns is transmitted through consumption of contaminated food. the pathogen has been considered as a potential source of contamination of raw milk and dairy products. this research was aimed to investigate prevalence of l. monocytogenes in raw milk in kerman region. in the summer of 2011, a total number of one hund...

Dairy cattle are a primary reservoir of Coxiella burnetii, which causes Q fever. However, no recent nationwide studies have assessed the prevalence and risks of Q fever in dairy cattle. We report >or=94% prevalence in samples of bulk tank milk from U.S. dairy herds tested during the past 3 years.

Abstract The chemical composition of goat milk, especially fatty acid profile is recently renewed due to the role monosaturated and polyunsaturated acids in human nutrition. These nutrients are important analysed connection with different breeds receiving same breeding feed. aim this study was analyse milk relation breeds. Specimens for analyses were collected from individual animals like Latvi...

INTRODUCTION Milk is considered to be a healthy, nutritious food product. Microbiological quality is an important aspect in evaluating the quality of milk. METHODOLOGY A total of 603 bulk tank milk samples from 221 farms distributed across ten different regions were collected for milk quality assessment. Quality was judged by total viable count, and the prevalence of two foodborne pathogens (...
