The present study was conducted to investigate the effect of subclinical mastitis on clinicopathological changes in Mastitic friesian. A total of 400 individual milk samples from clinically normal udder quarters of 100 diary friesians were examined microbiologically as well as by using California mastitis test (C.M.T.) for detection of subclinical mastitis and designing rapid diagnostic tests f...

Mastitis is one of the most important diseases affecting production and reproductive efficiency dairy cows. The objective this study was to estimate prevalence subclinical mastitis (SCMA) its effects on performance in postpartum In a cross-sectional survey, sample cows (n = 200) within their 10-40 days milk from smallholder farms 159) were selected tested for SCMA using California Test. They cl...

Bovine mastitis is a disease that concerns animals' welfare and increases the economic production losses. Bacterial agents such as Staphylococcus species are main causative agent of bovine mastitis. This bacterial expresses some inflammatory cytokines might enhance cell-mediated, which may promote pathogenesis The objective current study was to investigate innate immune response circulating lev...

AIM A cross-sectional study was conducted to estimate the prevalence and associated risk factors of mastitis in dairy cows. MATERIALS AND METHODS A total of 302 dairy cows were selected from all volunteer dairy farms in Ambo district of West Shewa Zone, Oromia region. Thorough clinical examination was made on all lactating cows for evidence of signs of clinical mastitis followed by collection...

Aim This study was conducted to determine the role of Staphylococcus in the formation of subclinical mastitis in cows and to isolate the phage against isolated Staphylococcus aureus strains. Materials and Methods In this study, 400 milk cows were screened by California Mastitis Test (CMT) for subclinical mastitis and 235 udders of 96 cows, which were determined to be positive, were evaluated ...

There is limited epidemiological knowledge on udder health in Kenyan dairy cattle that would aid in a pro-active approach towards mastitis prevention. The study objectives were: (1) to investigate the prevalence and distribution of clinical and subclinical mastitis in dairy cattle in Mukurwe-ini and Nakuru Districts, Kenya, and (2) to determine the antibacterial sensitivity of the organisms cau...

Among the bovine diseases, mastitis causes high economic losses in dairy production system. Nowadays, detection under field conditions is mainly performed by California Mastitis Test, which considered de facto standard. However, this method presents with problems of slowness and expensiveness chemical-reactive process, deeply dependent on an expert’s trained eye and, consequently, highly imprec...

The aim of this work was to identify and to characterise Staphylococcus aureus isolates associated with subclinical mastitis obtained from milk of lactating cows showing a California Mastitis Test (CMT) score result of traces, 1, 2 or 3. Coagulase, hemolysis, presence of capsule, slime formation, biofilm production, autoaggregation, hemagglutination and antibiotic susceptibility were assessed t...

Aim: To evaluate blood antioxidant profile and lipid peroxides in dairy cows with clinical mastitis. Materials and Methods: Twelve cases of clinical mastitis in cross-bred cows were selected based on physical examination of udder and milk, California Mastitis Test (CMT), Somatic Cell Count (SCC) and confirmation by bacteriological examination 5 of milk and requisite biochemical tests. Twelve la...

Screening tests for mastitis can play an important role in proactive mastitis control programs. The primary objective of this study was to compare the sensitivity and specificity of milk electrical conductivity (EC) to the California mastitis test (CMT) in commercial dairy cattle in South Africa using Bayesian methods without a perfect reference test. A total of 1848 quarter milk specimens were...
