This review deals with the role of viruses in the aetiology of bovine mastitis. Bovine herpesvirus 1, bovine herpesvirus 4, foot-and-mouth disease virus, and parainfluenza 3 virus have been isolated from milk from cows with clinical mastitis. Intramammary inoculations of bovine herpesvirus 1 or parainfluenza 3 virus-induced clinical mastitis, while an intramammary inoculation of foot-and-mouth ...

the sip gene encoding for a conserved highly immunogenic surface protein of streptococcus agalactiae was amplified using polymerase chain reaction (pcr) and subcloned into prokaryotic expression vector pet32a (+) and expressed as a recombinant protein in e. coli bl21 (de3). an indirect enzyme linked immunosorbent assay (elisa) was developed using the purified sip protein as a coating antigen, w...

background: the aim of this study was identification of the epidemiology of prototheca zopfii species from the milk samples of dairy cattle in isfahan, central iran. methods: milk samples were obtained from 230 dairy cattle, 130 with and 100 without mastitis, in isfahan. the samples were cultured in prototheca isolation medium (pim) and sabouraud's dextrose agar. all p. zopfii isolates were ide...

Bovine mastitis is very common in cows of both developed and developing countries. The prevalence of clinical and subclinical mastitis (SCM) varies from region to region. Hence, the present study was carried out to determine the prevalence of mastitis using three diagnostic tests by considering different risk factors like age, lactation, breed, season, quarters, and herd. The results showed tha...

Staphylococcus aureus is one of the main etiological agents of mastitis in different mammalian species. At present, it is unknown whether strains isolated from human mastitis cases share phenotypic properties and genetic background with those obtained from animal mastitis cases. Therefore, the objective of this study was to characterize S. aureus strains isolated from women with lactational mas...

Streptococcus agalactiae is a major contagious pathogen causing bovine sub-clinical mastitis. The present investigation was carried out to determine some phenotypic characteristics of the S. agalactiae strains isolated from bovine mastitis cases in dairy cows of Shahrekord in the west-center of Iran. One hundred eighty California mastitis test (CMT) positive milk samples were ...

background and objectives:   staphylococcus aureus is one of the main causatives of bovine mastitis. resistance of some strains to methicillin, can complicate the treatment of its infections. on the other hand, enterotoxin production is also im- portant. therefore, the aim of our study was to investigate the methicillin resistance and enterotoxin production in s. aureus isolates caused bovine m...

results a number of 7-11 repeats in the spa gene xr region were determined. strains with 10 repeats were65%, therefore they had the highest percentage in isolates. seven repeats strains were 20% and each of the strains with 8, 9 and 11 repeats had the frequency of 5%. s. aureus strains antibiotic resistance was 35%, 5%, 45% and 40% for tetracycline, amoxicillin, gentamicin and erythromycin resp...

Staphylococcus aureus is a major etiological agent of mastitis in ruminants. We report here the genome sequence of bovine strain Newbould 305, isolated in the 1950s in a case of bovine mastitis and now used as a model strain able to reproducibly induce chronic mastitis in cows.

The indiscriminate and injudicious administration of antibiotics and irrational treatment of bovine mastitis with different antibiotics have invited serious complications like multiple drug resistance. The present paper reports the microbiological examination and reporting of a clinical case of mastitis in cow and its recommended therapeutic management with the selected broad spectrum antibioti...
