Male infertility is related to urogenital tract bacterial infection. The significance of bacteriosperimia for male infertility has been paid attention in recent years. Asymptomatic bacteriosperm may play an important role. However, litter is known about the adverse influence of some uropathogenic bacteria on sperm function. The article reviewed some uropathogenic bacteria in male urogential tract and several pathomechanisms of effect bacteria on sperm function.

(Group A Streptococcus, GAS) is a human pathogen that causes local and systemic infections of the skin and mucous membranes. However, GAS is also found asymptomatically in the nasopharynx of infants. GAS infections, including pharyngitis and invasive pneumosepsis, pose significant public health concerns.

Hypervirulent Klebsiella pneumoniae (hvKP) poses an alarming threat in clinical settings and global public health owing to its high pathogenicity, epidemic success and rapid development of drug resistance, especially the emergence of carbapenem-resistant lineages (CR-hvKP). With the decline of the "last resort" antibiotic class and the decreasing efficacy of first-line antibiotics, innovative alternative therapeutics are urgently needed. Capsule, an essential virulence determinant, is a major cause of the enhanced pathogenicity of hvKP and represents an attractive drug target to prevent the devastating clinical outcomes caused by hvKP infection.

Importance: Doxycycline postexposure prophylaxis (doxyPEP) has been shown to decrease the incidence of bacterial sexually transmitted infections (STIs) among people assigned male sex at birth in clinical trials, but data from clinical practice are limited.
Objective: To describe early uptake of doxyPEP and evaluate changes in STI incidence following doxyPEP initiation.
Design, Setting, And Participants: This retrospective cohort study of adults (aged ≥18 years) dispensed HIV preexposure prophylaxis (PrEP) at Kaiser Permanente Northern California during November 1, 2022, to December 31, 2023, examined electronic health record data to compare HIV PrEP users dispensed and not dispensed doxyPEP and rates of bacterial STIs before and after starting doxyPEP.
Doxycycline Postexposure Prophylaxis and Sexually Transmitted Infection Trends.
JAMA Intern Med

San Francisco Department of Public Health, San Francisco, California.
Importance: Increasing rates of sexually transmitted infections (STIs) have been associated with rises in serious morbidity. While doxycycline postexposure prophylaxis (doxyPEP), a strategy in which individuals take doxycycline, 200 mg, after condomless sex to prevent bacterial STIs, has been shown to be efficacious in randomized clinical trials, doxyPEP's potential effect on population-level STI incidence is unknown.
Objective: To assess the association of citywide doxyPEP guideline release with reported chlamydia, gonorrhea, and early syphilis cases in men who have sex with men (MSM) and in transgender women in San Francisco, California.

This study tested whether combined ceftriaxone and adipose-derived mesenchymal stem cells (ADMSCs) would defend the spinal cord against acute spinal infection (ASI) in rodent. Adult-Male-SD rats were grouped into groups 1 (SC)/2 (ASI)/3 (ASI + ceftriaxone from days 2 to 28 after ASI induction)/4 (ASI + allogenic ADMSCs from day 2 for a total of 3 doses/3 consecutive intervals by intravenous injection)/5 (ASI + combined ceftriaxone and ADMSC) and spinal cord tissues were harvested by day 28. Circulatory levels of TNF-α/IL-6 at days 7 and 28, and these two parameters in spinal fluid at day 28 were lowest in group 1, highest in group 2, significantly lower in group 5 than in groups 3/4, and significantly lower in group 3 than in group 4 (all p < 0.
