ABSTRACT Two clonally unrelated Pseudomonas aeruginosa clinical strains, RON-1 and RON-2, were isolated in 1997 and 1998 from patients hospitalized in a suburb of Paris, France. Both isolates expressed the class B carbapenem-hydrolyzing β-lactamase VIM-2 previously identified in Marseilles in the French Riviera. In both isolates, thebla VIM-2 cassette was part of a class 1 integron that also encoded aminoglycoside-modifying enzymes. In one case, two novel aminoglycoside resistance gene cassettes,aacA29a and aacA29b, were located at the 5′ and 3′ end of the bla VIM-2 gene cassette, respectively. The aacA29a and aacA29b gene cassettes were fused upstream with a 101-bp part of the 5′ end of theqacE cassette. The deduced amino acid sequence AAC(6′)-29a protein shared 96% identity with AAC(6′)-29b but only 34% identity with the aacA7-encoded AAC(6′)-I1, the closest relative of the AAC(6′)-I family enzymes. These aminoglycoside acetyltransferases had amino acid sequences much shorter (131 amino acids) than the other AAC(6′)-I enzymes (144 to 153 amino acids). They conferred resistance to amikacin, isepamicin, kanamycin, and tobramycin but not to gentamicin, netilmicin, and sisomicin.

ABSTRACT Seven bla IMP-1-harboring Acinetobacter sp. isolates and one Pseudomonas putida clinical isolate were recovered from hospitalized patients. All isolates possessed a class 1 integron, named In86, carrying the same cassette array [bla IMP1, aac(6′)-31, and aadA1], which was plasmid located in five of the isolates. This report describes the ability of nonfermentative nosocomial pathogens to acquire and disseminate antimicrobial resistance determinants.

A resistência bacteriana é um mecanismo usado pelas bactérias para interferir na ação dos antibióticos e vem crescendo consideravelmente, se tornando um grande problema de saúde pública. O presente estudo avaliou o perfil de resistência de cepas de Staphylococcus aureus, Pseudomonas aeruginosa e Escherichia coli e a suscetibilidade das mesmas à alguns antimicrobianos. Para isso realizou-se uma pesquisa quantitativa utilizando os resultados de antibiogramas constantes nos livros de registro microbiologia do laboratório LAC - Santa Maria, situado em Colatina - ES. As amostras foram coletadas rotineiramente de pacientes internados em dois hospitais (Santa Maria e São José) e examinados pelo laboratório. No livro de registro obteve-se um total de 446 isolados microbianos identificados, dos quais 277 cepas foram identificadas como: S. aureus (36,5%), P. aeruginosa (32,5%) e E. coli (31%), os 169 restantes englobam os outros micro-organismos. Quanto ao perfil de resistência e sensibilidade, as cepas de P. aeruginosa foram mais sensíveis ao antibiótico sulbactam, E. Coli à ampicilina e ácido nalidíxico, e Staphylococcus à amicacina e ceftriaxone. Relaciona-se o maior isolamento de Stapylococcus, P. aeruginosa e E. coli provavelmente por serem micro-organismos encontrados colonizando ambientes hospitalares e a comunidade com grande potencial de disseminação. Quanto ao perfil de resistência se torna útil na seleção de drogas especificas para determinados micro-organismo. Palavras-chave: Resistência. Antibióticos. Micro-organismos.
