Antimicrobial resistance among bacteria isolated from urinary tract infections in females in Namibia, 2016-2017

Erastus H. Haindongo et al.

Summary: This study aimed to describe the national antimicrobial resistance situation of major bacterial uropathogens in females within the 14 Namibian regions. High resistance to ampicillin, quinolones, and sulfamethoxazole-trimethoprim among E. coli was reported, with concerning rates of resistance to third-generation cephalosporins at 22%.

Streptococcus mitis infective endocarditis in a patient with ventricular septal defect and orthodontic appliances

Dimitrios Amorgianos et al.

Summary: This case study describes a girl in a remote rural area in Scotland who developed Streptococcus mitis infective endocarditis on the right side due to abrasion of oral mucosa from arch wire during its adjustment in a dental clinic. The study highlights that fitting and adjustment of orthodontic appliances are not considered high-risk dental procedures, and antibiotic prophylaxis is not recommended even for high-risk infective endocarditis patients.

Maternal septicemia caused by Streptococcus mitis: a possible link between intra-amniotic infection and periodontitis. Case report and literature review

Piya Chaemsaithong et al.

Summary: This case report demonstrates maternal septicemia and intra-amniotic infection caused by S. mitis which might be attributed to periodontitis in women presenting with preterm PROM. Oral cavity examination should be included in the prenatal care to ensure good dental hygiene.

Genomic relatedness and clinical significance of Streptococcus mitis strains isolated from the urogenital tract of sexual partners

Carine R. Mores et al.

Summary: Research found that vaginal intercourse shifts the lower urinary tract microbiota, particularly noting an increase in Streptococcus mitis abundance. Isolates of S. mitis from both partners were genetically similar, indicating potential transmission. This post-coitus bloom in S. mitis may provide a window of opportunity for uropathogens to colonize the urinary tract.
