Biofilm formation is associated with a reduced susceptibility to antibiotics,
resulting in chronic infections by pathogens. This study aimed to determine
the association between intramammary infection with biofilm-producing bacteria
and chronic clinical mastitis in dairy cows. Eighty milk samples from acute
and chronic clinical mastitis cases were collected from 52 farms in Chiang Mai
and Lamphun provinces in northern Thailand. Forty-eight bacterial isolates were
identified from the milk samples. The most prevalent isolated bacteria were
streptococci, followed by staphylococci and Escherichia coli. Among these
bacterial isolates, only 14 (29.17%) could produce a biofilm, 10 of these isolates
were from chronic cases and 4 were from acute cases. There was no statistically
significant association between intramammary infection with biofilm-producing
bacteria and chronic clinical mastitis. However, biofilm production in vivo
and its association with the severity of mastitis should be investigated in
future studies.]]>Aarestrup, F.M., H.D. Larsen and N.E. Jensen,1999 Staphylococcus simulans strains isolated from cases of bovine mastitis.]]>66165170Arciola, C.R., L. Baldassarri and L.
