  • Coagulase Positive Staphylococcus intramammary infections in primiparous dairy cows
    Journal of Dairy Science, 1994
    Co-Authors: J R Roberson, Dale D Hancock, T E Besser
    Abstract:

    Objectives were to determine the prevalence of Coagulase-Positive staphylococcal IMI in primiparous cows at first parturition, to contrast the differences in Coagulase-Positive staphylococcal IMI in primiparous cows at parturition in herds with high and low prevalences of Coagulase-Positive staphylococcal IMI in the lactating herd, and to determine the percentage of primiparous cows having persistent Coagulase-Positive staphylococcal MI. Milk samples were collected aseptically from cows at the start and end of the study, at dry-off, and at parturition. Herds (n = 18) were split evenly into two categories: high (>10%) or low (<5%) prevalence of Coagulase-Positive staphylococcal IMI. At the start, the mean prevalence of Coagulase-Positive staphylococcal IMI in high prevalence herds was 30%, ranging from 13 to 65%, and in low prevalence herds was 2%, ranging from 0 to 5%. Overall the prevalence of Coagulase-Positive staphylococcal IMI in primiparous cows at parturition was 8.1% (67 of 828), ranging from 0 to 27%. Although primiparous cows from high prevalence herds had a higher prevalence of Coagulase-Positive staphylococcal IMI (9.2%; 40 of 436) at parturition than did primiparous cows from low herds (6.9%; 27 of 392), the difference was not significant. Of primiparous cows with Coagulase-Positive staphylococcal IMI at parturition, 43% had Coagulase-Positive staphylococcal IMI at least 2 mo after parturition. Primiparous cows with Coagulase-Positive staphylococcal IMI at parturition may represent significant reservoirs of infection to uninfected herdmates.

  • PHYSIOLOGY AND MANAGEMENT Coagulase-Positive Staphylococcus Intramammary Infections in Primiparous Dairy Cows1

    Objectives were to determine the prevalence of Coagulase-Positive staphy­ lococcal IMI in primiparous cows at first parturition, to contrast the differences in Coagulase-Positive staphylococcal IMI in primiparous cows at parturition in herds with high and low prevalences of Coagulase-Positive staphylococcal IMI in the lactating herd, and to determine the percentage of primiparous cows having persistent Coagulase-Positive staphylo­ coccal IMI.

  • Coagulase Positive Staphylococcus isolated from wildlife identification molecular characterization and evaluation of resistance profiles with focus on a methicillin resistant strain
    Comparative Immunology Microbiology and Infectious Diseases, 2016
    Co-Authors: Aneta Nowakiewicz, Grazyna Ziolkowska, Przemyslaw Zieba, Sebastian Gnat, Katarzyna Wojtanowiczmarkiewicz, Aleksandra Trościanczyk
    Abstract:

    Abstract The aim of the study was molecular analysis of Coagulase-Positive isolates of Staphylococcus bacteria obtained from wild animals and evaluation of their resistance to antimicrobial agents. A total of 76 rectal swabs were taken from wild animals. The species of the Staphylococcus isolates was determined by MALDI TOF MS, susceptibility to antimicrobials was evaluated by phenotypic and molecular methods, epidemiological analysis (ADSRRS-fingerprinting) was also carried out. MRSA isolate was typed by MLST and spa -typing. The animals tested, were carriers ( n  = 38) of Coagulase-Positive Staphylococcus ( S. aureus , S. pseudintermedius and S. delphini B). Analyzed isolates were resistant to 1 or 2 antimicrobials, which was confirmed by the presence of genes ( bla Z, erm A, erm B, msr A, tet K and tet M). A multi-drug resistant and methicillin-resistant isolate of S. aureus was obtained as well (MRSA, ST8, t1635, PVL-Positive and ACME-negative). The ADSRRS-fingerprinting method enabled interspecific and intraspecific differentiation of Coagulase-Positive Staphylococcus isolates, revealing a certain degree of correlation between the species of the isolate, and the degree of similarity between the isolates. The presence of resistance genes in 13% (5/38) of the isolates obtained from wild animals, including one methicillin-resistant isolate, is relatively small in comparison to the degree of colonization by resistant strains in humans, livestock or pets. Nevertheless, due to the possibility of contact between wild animals, domestic animals and humans, transmission of resistant strains is possible, as suggested by our isolation of a MRSA strain typed as ST8 and specific spa type t1635, which had previously been isolated exclusively from humans.
