Abstract

Reduction in long-term milk yields represents a notable share of the economic losses caused by bovine mastitis. Efficient, economic, and safe measures to prevent these losses require knowledge of the causal agent of the disease. The aim of this study was to investigate pathogen-specific impacts of...

AbstractFull Text

Background: Coagulase-negative staphylococci (CoNS) are the most common bovine mastitis causing bacteria in many countries. It is known that resistance for antimicrobials is in general more common in CoNS than in Staphylococcus aureus but little is known about the antimicrobial resistance of...

Abstract

The aim of this study was to determine risk factors for bovine intramammary infection (IMI) associated with the most common bacterial species in Finland. Large databases of the Finnish milk-recording system and results of microbiological analyses of mastitic milk samples from Valio Ltd. (Helsinki,...

Abstract

Real-time PCR techniques are increasingly used to detect udder pathogens from milk samples collected non-aseptically at routine milk recording. The objectives of this study were (1) to estimate the statistical associations between cycle threshold (Ct) values for Staphylococcus aureus in...

AbstractFull Text

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...

Abstract

Mastitis, inflammation of the mammary gland, is an important cause of disease, mortality, and production losses in dairy and meat sheep. Mastitis is commonly caused by intramammary infection with bacteria, which can be detected by bacterial culture or PCR. PathoProof (Thermo Fisher Scientific Ltd., ...

Abstract

Reliable identification of the aetiological agent is crucial in mastitis diagnostics. Real-time PCR is a fast, automated tool for detecting the most common udder pathogens directly from milk. In this study aseptically taken quarter milk samples were analysed with a real-time PCR assay (Thermo...

Abstract

A database containing pathogen-specific information on mastitis has been established in Finland. The data consist of the results from routine milk samples collected from clinical and subclinical mastitis and submitted to laboratories all over the country. In the database, bacteriological...

Abstract

Isolates of various species of coagulase-negative staphylococci (CNS) from extramammary swab samples were compared with isolates of bovine mastitis CNS species. Swab samples were taken from perineum skin and udder skin, teat apices and teat canals of lactating dairy cows of the research dairy herd...

Abstract

Mastitis caused by coagulase-negative staphylococci (CNS) has recently increased in Finland and in other countries. CNS-infection usually causes subclinical or mild clinical mastitis. Increased somatic cell count in milk results in loss of income for farmers. Milk production of the infected...
