Abstract Purpose Staphylococcus aureus ( S. ) is the most important pathogen involved in bovine mastitis dairy production. produces a spectrum of extracellular protein toxins and virulence factors which are thought to contribute pathogenicity organism. The aim this work was isolate molecular characterize associated with subclinical central part Ethiopia. Methods A total 265 lactating cows from ...

The aim of the study was to analyse the variability of the leukocyte population and lymphocyte subpopulation in peripheral blood in ewes of different age and mammary gland health status and with different genotype in DBR1 (MHC II) gene. Blood samples were collected 3 times from 24 ewes of Polish Heath Sheep at the age of 6, 12 and 24 months. Milk samples were collected from ewes at the age of 2...

This study compared the different leucocyte populations in milk from udders infected with different mastitic pathogens and in different stages of infection. Milk samples were collected from quarters free of intramammary infection, acutely infected with Escherichia coli or Staphylococcus aureus and chronically infected with S. aureus, coagulase-negative staphylococci (CNS) or Streptococcus dysga...

The objectives of this experiment were to determine interrelationships among mastitis indicators and evaluate the subclinical mastitis detection ability of infrared thermography (IRT) in comparison with the California Mastitis Test (CMT). Somatic cell count (SCC), CMT, and udder skin surface temperature (USST) data were compiled from 62 Brown Swiss dairy cows (days in milk=117+/-51, milk yield=...

Mastitis is an important disease of dairy cows, and it causes huge economic losses to farm owners due a decrease in milk production, reduction quality, increase the cost cow treatment. A crosssectional study was conducted Southern Ethiopia’s Silte zone from October 2020 June 2021 aimed estimate mastitis prevalence, assess related risk factors, identify prevalent bacterial causes. Three hundred ...

BACKGROUND The Finnish dairy herd recording system maintains production and health records of cows and herds. Veterinarians and farmers register veterinary treatments in the system. Milk samples for microbiological analysis are routinely taken from mastitic cows. The laboratory of the largest dairy company in Finland, Valio Ltd., analyzes most samples using real-time PCR. This study addressed p...
