ABSTRACT Although antibiotic-resistant pathogens pose a significant threat to human health, the environmental reservoirs of the resistance determinants are still poorly understood. This study reports the detection of resistance genes (ermB, mecA, mupA, qnrA, qnrB and tetL) to antibiotics among certain culturable and unculturable bacteria associated with the marine sponge Petromica citrina. The antimicrobial activities elicited by P. citrina and its associated bacteria are also described. The results indicate that the marine environment could play an important role in the development of antibiotic resistance and the dissemination of resistance genes among bacteria.

ABSTRACT:  We compared the potential of routine techniques used for the identification of Staphylococcus species, aiming to evaluate their accuracy in the detection of 43 Staphylococcus chromogenes strains isolated from bovine mastitis that, despite being a coagulase-negative species, are able to clot plasma. These strains could be mistakenly suspected to be S. aureus and lead to an unappropriated treatment of the disease. MALDI-TOF, PCR-RFLP of the chaperonine gene groEL, and sequencing of the 16S rRNA and elongation factor Tu gene tuf were employed. Results from the four methods were coincident for only half of the strains because of the low accuracy of the groEL PCR-RFLP (51.2% accuracy). Even though all the sequencing results were identical, the high...
