“…Em estudo realizado por Schultz (2004), onde foram analisadas 202 bactérias, 78,0% eram Staphylococcus coagulase negativa e 44,0% destes foram resistentes a mais de um antibiótico. Destaca-se então a importância dos SCN na participação do processo infeccioso da glân-dula mamária, pois a resistência aos tratamentos causa persistência de casos crônicos no rebanho que podem atuar como fontes de infecção para outros animais do rebanho (Archer 1994).…”

Objetivou-se com este estudo avaliar a sensibilidade antimicrobiana in vitro de 291 isolados de Staphylococcus spp. recuperados de amostras de leite de vacas com mastite subclínica, em 15 propriedades rurais localizadas na Região Metropolitana do Recife (A), Agreste (B) e Zona da Mata (C) do estado de Pernambuco. Dos 291 isolados, 170(58,4%) foram classificados como Staphylococcus coagulase negativa (SCN), 84(28,9%) como Staphylococcus aureus e 37(12,7%) como Staphylococcus coagulase positiva (SCP). Para o estudo do perfil de sensibilidade a antimicrobianos empregou-se a técnica de difusão em discos, foram avaliadas 16 drogas antimicrobianas utilizadas no tratamento das mastites. O antibiótico que apresentou melhor eficácia in vitro foi a associação entre neomicina + bacitracina + tetraciclina com percentuais de 98,4%, 99,3%, 89,7% para as regiões A, B e C, respectivamente. O antibiótico menos eficaz foi a ampicilina que apresentou 56,5% de resistência para as amostras da região A, 72,8% para a região B e 71,8% na região C. Os resultados obtidos mostram a necessidade da realização periódica de testes de sensibilidade in vitro, pois existem variações no perfil de sensibilidade e resistência que podem comprometer o tratamento do animal bem como os programas de controle da mastite bovina causada pelo Staphylococcus spp.

“…A review on antimicrobial resistance in CNS (mainly S. epidermidis) from humans was published by Archer and Climo [6]. CNS are an increasing problem in nosocomial infections and it was stated that this may be due to the increase of multiresistant CNS isolates.…”

“…According to their resistance phenotypes, they are classified into another four groups, one of which consists of eight subgroups (= revised Bush scheme). Staphylococcal β-lactamases are usually assigned to molecular class A and Bush group 2a [35]; they have been found in S. aureus as well as in CNS [6,40,67]. In human staphylococci, the β-lactamase (blaZ) gene is inducibly expressed.…”

Antimicrobial resistance in staphylococci from animals with particular reference to bovine Staphylococcus aureus, porcine Staphylococcus hyicus, and canine Staphylococcus intermedius

-Besides their role as commensals on the skin and mucosal surfaces, staphylococci may be involved in a wide variety of diseases in animals. Staphylococcal infections in animals are mainly treated with antimicrobial agents and as a consequence, staphylococci from animal sources have developed and/or acquired resistance to the respective antimicrobial agents. Resistance statistics obtained from national monitoring programmes on staphylococci from cattle and pigs, but also from surveillance studies on staphylococci involved in diseases in dogs are reported and reviewed with regard to their comparability. This review mainly focusses on the genetic basis of antimicrobial resistance in staphylococci of animal origin. Particular attention is paid to resistance to those antimicrobial agents which are most frequently used in veterinary medicine, but also to antimicrobial agents, such as chloramphenicol and mupirocin, which are used in specific cases for the control of staphylococcal infections in pets and companion animals. In addition, plasmids and transposons associated with the respective resistance properties and their ways of spreading between members of the same or different staphylococcal species, but also between staphylococci and other gram-positive bacteria, are described.antimicrobial resistance / Staphylococcus / animal origin / epidemiology / horizontal gene transfer Vet.

“…The antimicrobial resistance profiles of CNS have been monitored. Archer & Climo (1994) indicated that the percentage of CNS resistant to meticillin, oxacillin and nafcillin amongst HAI strains increased from 20 to 60% between 1980 and 1989, according to The National Nosocomial Infection Survey, which included data collected from selected hospitals in the USA. An even larger increase was reported at university hospitals in the state of Iowa, where the frequency of bacteraemia caused by CNS increased from 5.2 to 42 cases per 10 000 admissions from 1984 to 1987 (Martin et al, 1989).…”
