BACKGROUND S. aureus is one of the main pathogens involved in ruminant mastitis worldwide. The severity of staphylococcal infection is highly variable, ranging from subclinical to gangrenous mastitis. This work represents an in-depth characterization of S. aureus mastitis isolates to identify bacterial factors involved in severity of mastitis infection. METHODOLOGY/PRINCIPAL FINDINGS We emplo...

Mastitis control is based upon adoption of preventive control strategies including good milking hygiene, the use of properly functioning milking equipment, provision of clean and dry housing areas, sound nutritional programs and proper identification and treatment of cows that are infected with subclinical and clinical mastitis. Worldwide, many dairy farmers have adopted these procedures and pr...

Aim: Bovine mastitis is the most economically important disease affecting dairy cattle worldwide from an economic, diagnostic and public-health point of view. The present study aimed to isolate and identify of bacteria causes mastitis in dairy cows and to evaluate the antibacterial activities of some selected medicinal plants extracts comparing antibiotics used in the treatment of mastitis in E...

Background: In the present study two hundred milk samples were collected from cows and buffaloes with no history of clinical mastitis in ongoing lactation, Sirohi district Southern Rajasthan. Methods: The pooled sample (collected each quarter) examined for status subclinical by Modified California test Somatic cell count respectively. Positive further investigated isolation identification major...

BACKGROUND Mastitis is the most important and costly disease in dairy goat production. Subclinical mastitis is common in goats and is mainly caused by contagious bacteria. Several methods to diagnose subclinical mastitis are available. In this study indirect measurement of somatic cell count (SCC) by California Mastitis Test (CMT) and direct measurement of SCC using a portable deLaval cell coun...

The objective of the present study was to determine whether there was an association between the in vitroantimicrobial sensitivity test results of subclinical mastitis pathogensand bacteriological cure following intramammary treatment using a combination of nafcillin, penicillin, and streptomycin (NPS). Eighty-six intramammary pathogens from 43 cows were examined inthis study. Most intramammary...

Subclinical mastitis in cattle is a pathological condition that causes financial burden on the dairy industry. In addition, it puts public sector at risk when pathogens of animal origin are present unpasteurized milk and products may enter human food chain cause serious illnesses. Our study aimed to determine percentage pathogenic Escherichia coli causing subclinical cows Mosul city by confirmi...

The current study was planned to investigate the potential risk factors and their association with mastitis in Cholistani cattle. For this purpose milk samples were collected and examined for mastitis using California Mastitis Test. The results showed an overall 21.96% prevalence of subclinical mastitis. The analysis of variance did not show significant association of tail size, live body weigh...

BACKGROUND Gyr cows are well adapted to tropical conditions, resistant to some tropical diseases and have satisfactory milk production. However, Gyr dairy herds have a high prevalence of subclinical mastitis, which negatively affects their milk yield and composition. The objectives of this study were (i) to evaluate the effects of seasonality, mammary quarter location (rear x front), mastitis-c...

BACKGROUND Mycoplasma mastitis is increasingly posing significant impact on dairy industry. Although the effects of major conventional mastitis pathogens on milk components has been widely addressed in the literature, limited data on the effects of different Mycoplasma and Acholeplasma spp. on milk quality and quantity is available. The aim of this study was to determine the casual relationship...
