Mastitis Pathogens Isolated from Samples of Milk in Dairy Cows and Their Resistance against Antimicrobial Agents
The objective of this study was to evaluate the effectiveness of different antibiotics against mastitis causing microorganisms during first phase of lactation in herd of 320 Holstein cows in east of Slovakia. Milk samples from quarters were cultured and identified bacteria were subjected to antimicrobial susceptibility test by disc diffusion method to a large number of antibiotics. The results ...
متن کاملCharacterization of Aerococcus viridans isolated from milk samples from cows with mastitis and manure samples.
Thirty-eight Aerococcus viridans isolates were obtained from milk from 478 cows with clinical mastitis in a farm during the periods between November 2011 and February 2012, and between December 2012 and March 2013. Additional isolates were obtained from processed manure (a mixture of composted manure, straw and hydrated lime) and bedding materials. The processed manure was later used to cover t...
متن کاملDrug resistance in isolated bacteria from milk of sheep and goats with subclinical mastitis in Shahrekord district
Four-hundred milk samples from half udders of 20 flocks of native breed goats were asepticallycollected. The samples were examined by California mastitis test (CMT). Twenty-one (5.25%) of 400 wereCMT-positive. The CMT-positive samples were then cultured and the following bacteria were isolated:Staphylococcus aureus in 3 (14.28%), CNS (coagulase-negative staphylococci) in 14 (66.66%), streptococ...
متن کاملStudy on some characteristics of Staphylococci isolated from sheep sub clinical mastitis milk in Shahrekord, Iran
Introduction: Staphylococci release a large number of enzymes. Some of these, such as coagulase, beta lactamase, hemolysins and biofilms are considered indices of pathogenicity. The aim of the current study was based on the isolation and identification of Staphylococcus aureus and coagulase negative Staphylococci (CNS) strains from sheep sub clinical mastitis and examining their biofilm, beta l...
متن کاملBulk tank milk somatic cell count and sources of raw milk contamination with mastitis pathogens
The objective of this study was to probe the relationship between prevalence of selected principal mastitis pathogens and somatic cell counts in bulk tank milk samples. The sources of milk contamination were evaluated. The samples were collected from 298 dairy herds (with approximately 32 000 dairy cows). Only 48.3% of the bulk tank milk samples were free of contamination of pathogens of intere...
