Abstract

II. The first part of this article is concerned with the behaviour of the groups of mastitis and other streptococci from milk samples described earlier by the workers at Storrs, on the differential crystal violet-aesculin medium described by EDWARDS [V. B. 4. 803]. All of 92 cultures of Str....

Abstract

Forty-four cows were divided into 2 equal and comparable groups according to their serum titres of detectable inhibitors to staphylococcal hyaluronidase. The animals in one group were given 6 s/c vaccinations with 10-ml. amounts of formolized 18-hour broth cultures of Str. agalactiae Strain A 100...

Abstract

Group N streptococci with antibiotic activity were isolated from milk samples from an experimental herd. The streptococci inhibited cultures of coagulase-positive and coagulase-negative staphylococci and cultures of Str. agalactiae, Micrococcus flavus and Corynebacterium pyogenes[Arcanobacterium...

Abstract

Milk samples were examined bacteriologically from 490 quarters of 139 cows in 14 herds in the Taipei district. Str. agalactiae was isolated from 28% of the quarters, 46% of the cows, and 86% of the herds. Staph. aurous was isolated from 14% of the quarters, 32% of the cows, and 79% of the herds....

Abstract

In this paper, we analyzed a very large field data set on intramammary infections (IMI) and the associated somatic cell count (SCC) in dairy cows. The objective of the study was to analyze the impact of coagulase-negative staphylococci (CNS) IMI on cow SCC, both mean and variability, and on the...

Abstract

Accurate identification of mastitis pathogens is often compromised when using conventional culture-based methods. Here, we report a novel, rapid assay tested for speciation of bacterial mastitis pathogens using high-resolution melt analysis (HRMA) of 16S rDNA sequences. Real-time PCR amplification...

Abstract

For more than 30 yr, a control plan for Streptococcus agalactiae and Staphylococcus aureus has been carried out in more than 1,500 dairy herds of the province of Brescia (northern Italy). From 2010 to 2011, the apparent prevalence of Strep. agalactiae has been relatively stable around 10%, but the...

Abstract

Twenty-nine strains of mastitis pathogens were used to study the antibacterial activity of the cell-free supernatants (CFS) of 25 strains of Lactococcus lactis ssp. lactis. Out of the tested strains, only the CFS of L. lactis LL11 and SL153 were active, inhibiting and killing most of the pathogens. ...

Abstract

Three hundred subclinically infected quarters of 259 Holstein cows infected with gram-positive bacteria were selected via quota sampling based on the California Mastitis Test (CMT) result and were divided randomly and equally into treatment and test groups. Quarters of test group (n=150 in 128...
