The Antistreptococcal Property of Milk
The ability of lactenin to prevent the multiplication of group A streptococci when milk becomes contaminated with that organism accounts in part at least, for the infrequency of milk-borne streptococcal epidemics. From epidemiological studies it has been shown that most such epidemics arise from the consumption of raw milk in which streptococci occur as a result of bovine mastitis due to group ...
متن کاملRelationship between in vitro susceptibility of bovine subclinical mastitis isolates and bacteriological outcome of intramammary treatment with cefquinome
The objective of the present study was to determine whether there was an association between the in vitro antimicrobial susceptibility test results of subclinical mastitis pathogens and bacteriological outcomes of intramammary treatments using cefquinome. A total of 110 intramammary pathogens from 51 cows were assessed in this study. Most intramammary infections were due to coagulase-negative s...
متن کاملThe Significance of Human Double Zone Beta Hemolytic Streptococci in the Udder of the Cow
Human strains of double zone beta hemolytic streptococci produced mastitis in 11 quarters of 4 young cows. Following the acute phase of the infection, the streptococci were eliminated from 6 quarters at various intervals. However, sufficient positive infections were maintained throughout the period of observation to show that the human strains can produce the same degree of infection as bovine ...
متن کاملStudies in Bovine Mastitis
Aside from the streptococci, micrococci have been the next most frequent group of organisms isolated from inflamed udders. They produce various types of disease. Some give rise to only a mild catarrh of the larger milk ducts and cystern, while others produce more or less severe parenchymatous inflammation. On the whole, the prognosis is more favorable with micrococcic infection than with that a...
متن کاملIdentification and molecular characterization of serological group C streptococci isolated from diseased pigs and monkeys in Indonesia.
The present study was designed to comparatively investigate 34 beta-hemolytic streptococci isolated from infected pigs and monkeys from various islands in Indonesia. According to the serological and biochemical data, all 34 isolates were Lancefield's serological group C streptococci and could be identified as Streptococcus equi subsp. zooepidemicus. Of the 34 group C streptococci investigated, ...
