Incidence and importance of subclinical mastitis in sheep.
The incidence of positive CMT, indicative of subclinical mastitis, was studied in a flock of purebred Targhee ewes from four selection lines. The incidence of positive CMT was found to be random at lambing with respect to age and line of ewe, number of lambs born and weaned and sex of lambs, but at docking (3 to 7 weeks after lambing) increased with increasing age of ewe and number of lambs bor...
متن کاملRelationship between in vitroantimicrobial sensitivity of bovine subclinical mastitis isolates and treatment outcome in lactating dairy cows
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...
متن کاملDrug resistance in isolated bacteria from milk of sheep and goats with subclinical mastitis in Shahrekord district
Four-hundred milk samples from half udders of 20 flocks of native breed goats were asepticallycollected. The samples were examined by California mastitis test (CMT). Twenty-one (5.25%) of 400 wereCMT-positive. The CMT-positive samples were then cultured and the following bacteria were isolated:Staphylococcus aureus in 3 (14.28%), CNS (coagulase-negative staphylococci) in 14 (66.66%), streptococ...
متن کاملPrevalence and molecular characterization of staphylococci isolated from sheep with subclinical mastitis in West-Azerbaijan province, Iran
This study was conducted to investigate the prevalence of subclinical mastitis caused by Staphylococcus spp. in ewes in West-Azerbaijan province of Iran. Molecular characterization of isolated Staphylococcus spp. from diseased ewes were performed using polymerase chain reaction (PCR) followed by restriction fragment length polymorphism (RFLP) and DNA sequencing of gly...
متن کاملChanges in milk composition as affected by subclinical mastitis in sheep and goats
The present study focused on gaining a better insight into how subclinical mastitis at the gland level in dairy sheep and goats affects milk yield and compositional changes in relation to curd yield. Animals chosen for the study had one udder half infected with identified coagulase-negative staphyloccocci (CNS) species and the contra-lateral gland was free of bacteria. Udder halves were tested ...
