Antimicrobial susceptibilities and clinical sources of Facklamia species.
نویسندگان
چکیده
Facklamia spp. are gram-positive cocci, arranged in short chains or diplos, and resemble viridans streptococci on 5% sheep blood agar. Eighteen strains representing four species of Facklamia were isolated from blood cultures, an abscess, bone, cerebrospinal fluid, gall bladder, vaginal swab, and one unknown source. Cultures were tested against 15 antimicrobial agents by using the broth microdilution MIC method. Reduced susceptibilities to the beta lactams, erythromycin, clindamycin, trimethoprim-sulfamethoxazole, and tetracycline were found. These results indicate that the susceptibilities of the Facklamia species are varied and that some strains have resistance patterns which may present difficulty in managing systemic infections in patients.

Antimicrobial susceptibilities of Aeromonas strains isolated from clinical and environmental sources to 26 antimicrobial agents.
We determined the susceptibilities of 144 clinical and 49 environmental Aeromonas strains representing 10 different species to 26 antimicrobial agents by the agar dilution method. No single species had a predominantly nonsusceptible phenotype. A multidrug nonsusceptible pattern was observed in three (2.1%) clinical strains and two (4.0%) strains recovered from diseased fish. Common clinical str...

Streptococcus agalactiae is a major contagious pathogen causing bovine sub-clinical mastitis. The present investigation was carried out to determine some phenotypic characteristics of the S. agalactiae strains isolated from bovine mastitis cases in dairy cows of Shahrekord in the west-center of Iran. One hundred eighty California mastitis test (CMT) positive milk samples were ...
متن کاملFacklamia ignava sp. nov., isolated from human clinical specimens.
Two strains of a hitherto-undescribed gram-positive, catalase-negative coccus isolated from human sources were characterized by phenotypic and molecular taxonomic methods. Comparative 16S rRNA gene sequencing studies demonstrated that the unknown strains are genealogically identical and constitute a new line close to, but distinct from, Facklamia hominis. The unknown bacterium was readily disti...
متن کاملFacklamia Species as an Underrecognized Pathogen
Facklamia species are a rarely reported etiology of clinical infection with few cases described in literature. However, the prevalence of infection may be underestimated due to challenges in species identification. We describe 3 cases of Facklamia species bacteremia and the unique microbiologic aspects inherent to this genus that make it particularly challenging to identify. In addition, given ...
متن کاملPrevalence and antimicrobial susceptibilities of coagulasenegative Staphylococci isolated from mammary secretions in pregnant Holstein heifers
Mammary secretions of 913 quarters from 229 pregnant Holstein heifers were obtained aseptically to determine the prevalence of coagulase-negative Staphylococci isolated during periparturient period. Quarter samples were collected 14 to 10 days before expected parturition. Analysis of culture data indicated that 78.5% (717/913) of samples were negative, 20.5% (187/913) contained coagulase-negati...
