ABST RACT In this study it was aimed to investigate the potential virulence genes (gelatinase [gelE]), adhesion-associated protein [EfaAfs], enterococcal surface protein [esp], cytolysins [cylA, cylM, cylB], sex pheromones [cpd, cob, ccf], aggregation substance [aggA], enhanced expression of pheromone [eep]) of Enterococcus faecalis strains isolated from mastitic bovine milk samples with polyme...

© 2002 Feedstuffs. Reprinted with permission from Vol. 74, No. 27, July 8, 2002 The practice of feeding pooled waste/ mastitic milk to young calves seems to have increased as dairies have grown larger, creating a larger pool and the means to segregate this milk from saleable milk. This was acknowledged by the authors of the 1996 National Animal Health Monitoring System (NAHMS) study (Feedstuffs...

The purposes of this study were to investigate the levels of lactoferrin in 180 normal and 132 mastitic camel milk samples and to elucidate the effect of age, lactation stage, presence of pathogens, and somatic cell counts (SCC) on the concentration of lactoferrin in camel milk using radial immunodiffusion test. The mean log concentration of lactoferrin from mastitic camels (3.8 ± 0.67) was sig...

A study carried out to compare the compositional quality of milk from healthy and mastitic buffaloes revealed mean ± S.E. content of sodium, potassium, chloride, protein, lactose and SNF in milk of healthy quarters as 40.00±1.19 mg/dl, 102.00±0.06 mg/dl, 0.126±0.006 per cent, 3.33±0.03 gm/dl, 5.92±0.01 gm/dl and 8.77±0.05 gm/dl, respectively. The milk from clinically infected quarters showed 85...

Inflammation and infection of bovine mammary glands, commonly known as mastitis, imposes significant losses each year in the dairy industry worldwide. While several different bacterial species have been identified as causative agents of mastitis, many clinical mastitis cases remain culture negative, even after enrichment for bacterial growth. To understand the basis for this increasingly common...

AIMS To determine the prevalence and molecular characteristics of Shiga toxin-producing Escherichia coli (STEC) isolates from bovine mastitic milk in Brazil. METHODS AND RESULTS A total of 2144 milk samples from dairy cattle showing mastitis were screened for the presence of E. coli. A total of 182 E. coli isolates were selected and examined. All were subjected to dot blot analysis using the ...

mastitis is one of the most important diseases of dairy cattle in the world. the identification and characterization of the constituent proteins in milk can be useful for studying the biochemistry and pathogenesis of mastitis. in this study, the electrophoretic patterns of milk from 10 healthy and 30 mastitic cows were studied. all of the latter milk samples were california mastitis test (cmt) ...

This study was undertaken to investigate the effectiveness of California mastitis test (CMT), white side test (WST), chlorine test and electrical conductivity (EC) in the diagnosis of subclinical mastitis in dairy cows in a comparison to somatic cell count (SCC) as a standard method for detection of subclinical mastitis. One hundred random samples of cow’s milk were collected from different dai...

In the microbiological investigation, made on samples of normal; (n=412) and mastitic (n=482) milk, proceeded from eight dairy cows farm, in Transilvania, it was signal the presence of the algae without chlorophyl belonging to Prototheca, forming together with bacteria and fungi the micro flora of the mammary gland. The alga content of normal milk was signaled only in two farms (2.27%, respecti...
