Scan to discover onlineBackground & Objective: This study was designed to determine the prevalence of serotypes, virulence-associated genes, and antimicrobial resistance of Streptococcus agalactiae in pregnant volunteers attending a major maternity hospital in Iran. Methods:The virulence determinants and antimicrobial resistance profiles of 270 Group B streptococcus (GBS) samples were assessed in the adult participants. The prevalence of GBS serotypes, virulence-associated genes, and antimicrobial resistance of the isolates was determined. Results:The GBS prevalence in the vaginal, rectal, and urinal carrier rates were 8.9%, 4.44%, and 4.44%, respectively, with no concomitant colonization. The serotypes Ia, Ib, and II were at a 1:2:1 ratio. The rectal isolates, harboring CylE, lmb, and bca genes, were of serotype Ia, susceptible to vancomycin. The serotype Ib from urine samples carrying three distinct virulence genes was susceptible to Ampicillin. In comparison, the same serotype with two virulence genes of CylE and lmb exhibited sensitivity to both Ampicillin and Ceftriaxone. The vaginal isolates belonged to serotype II with the CylE gene or serotype Ib with CylE and lmb genes. These isolates harboring the CylE gene were resistant to Cefotaxime. The overall antibiotic susceptibility range was 12.5-56.25%. Conclusion:The findings broaden our understanding of the pathogenicity of the prevailing GBS colonization and predict different clinical outcomes.

“…They are considered to be the source of many gram-positive and negative bacterial infections that can be transmitted especially through urine saliva, blood, wounds and breathing to humans. In particular, immunocompromised individuals and children are in the risk group (2). Citrobacter freundii is a species of facultative anaerobic Gram-negative bacteria of the family Enterobacteriaceae.…”

A 1-year-old Green iguana (Iguana iguana) was presented to the clinics with a complaint of a slowly growing mass on the left mandible, at the same time symptoms of weakness and loss of appetite for several weeks. In the clinical examination, it was noted that the mass was quite firm, invasive to the region, and had a necrotic appearance. It was removed by surgical operation and sent to the laboratory for investigation. In the microbiological evaluation, Citrobacter freundii was isolated and identified very intensely.
