We studied the correlation between genetic transfer of tetM determinant in Tn916 conjugative transposon by urogenital mycoplasmas (Mycoplasma hominis and Ureaplasma urealyticum) and changes in the bacterial repertoire during treatment with a tetracycline antibiotic. Basic conditions favoring the nonspecific transfer of tetM determinant into mollicute cells are determined and the allele polymorphism of tetM determinant in clinical strains of M. hominis and U. urealyticum is evaluated. The structure of tetM gene in clinical mycoplasma and ureaplasma strains is characterized by a peculiar mosaic pattern and differs from all previously described alleles of this gene. The results suggest that tetracycline resistance in mollicutes is determined by mechanisms alternative to genetic transfer of tetM determinant.

Group B Streptococcus (GBS) or Streptococcus agalactiae is a pathogen that causes infections during pregnancy. The aim of this study was to investigate the antibiotic sensitivity profiles, capsule genotypes and biofilm forming capabilities of GBS isolates obtained from pregnant women . The study included 252 pregnant women who applied to Adana Gynecology and Children's Hospital between 2018 and 2023.

Background: Group B Streptococcus (GBS) is a leading cause of neonatal meningitis and sepsis and an important cause of disease in adults. Capsular polysaccharide and protein-based GBS vaccines are currently under development.
Methods: Through national laboratory-based surveillance, invasive GBS isolates were collected from patients of all ages between 2019 and 2020.

() is a pathogen of significant concern in food due to its ability to survive and multiply under harsh environmental conditions, such as high osmotic pressure, low temperatures, and freezing. This bacterium can cause listeriosis, a severe infection particularly dangerous for high-risk groups including newborns, pregnant women, and immunocompromised patients, due to its high morbidity and mortality rates. This study aimed to investigate the molecular epidemiological characteristics of isolated in Chongqing, southwest China.

The genus Enterococcus is increasingly recognized for its involvement in various human infections, with several species known to be pathogenic. This study characterized Enterococcus sp. SMC-9, isolated from bile of a patient with cholangitis, and compared its characteristics with those of Enterococcus montenegrensis CoE-012-22T, recently isolated from dried beef sausage.
