urinae causes urinary tract infections; the other species, A. viridans, a gram-positive coccus considered a contaminant in cultures, has been associated with human infections that included bacteremia Complete Genome Sequences of Aerococcus christensenii CCUG 28831 T, Aerococcus sanguinicola CCUG 43001 T, Aerococcus urinae CCUG 36881 T, The genus Aerococcus encompasses eight species, which are Gram-positive cocci. For a long time, Aerococcus viridans (1953) was the only known species. Historically, A. urinae is considered to be an under recognized cause of human disease [4, 20, 21]. A. urinae is classically described on gram stain as being arranged in tetrads but also has been known to occur in clusters and irregular pairs.

The isolate was identified as Aerococcus species by phenotypic tests (colony morphology, Gram stain morphology, catalase, growth in 6.5% NaCl, pyrrolidonyl-arylamidase, leucine-aminopeptidase, β-glucuronidase, hippurate hydrolysis, and vancomycin susceptibility) and was confirmed to be Aerococcus urinae by sequence analysis of 16S rRNA DNA.

Adding Gram stain to the bacteria turned them violet, and therefore the bacteria were Gram-positive. This can be seen in microscopy in Image 2. The patient was treated with antibiotics. Aerococcus urinae Aerococcus urinae is a relatively new species of bacteria in clinical and microbiological practice, first reported in Figure 1 Gram stain of Aerococcus urinae.
Bacterial Isolate Type: Gram-Negative.
A. urinae is a gram-positive coccus occurring in tetrads or pairs, similar to the α-hemolytic Streptococci, which is commonly found in the urinary tract in children and elderly people. Se hela listan på hindawi.com A gram-stain-positive, facultatively anaerobic, non-spore-forming, catalase-negative, coccoid-shaped bacterial strain, designated BV2(T), was isolated from the vaginal mucosa of a beef cow in Japan. Phylogenetic analysis showed that the isolate shared high 16S rRNA gene sequence similarity (92.9 %) … Actinobaculum was isolated from urine only after prolonged incubation in 5% CO(2) after discrepancy between urine Gram stain and initial culture results was observed. Additional patients were diagnosed using this method.
