Surgical face masks and downward dispersal of bacteria
Analysis of the number of bacterial colonies grown on each agar plate showed a statistically significant reduction in the median number of colonies cultured per plate when the mask was worn, suggesting that for procedures lasting less than 15 min, the operator should wear a face mask.
The effect of facial hair and sex on the dispersal of bacteria below a masked subject
To reduce the risks of contamination of the sterile field when face masks are worn females and bearded males should avoid wiggling the face mask.

All isolates of E. coli from patients with bacteraemia between October 1986 and the end of September 1988 were assessed for the presence of the O15 antigen and for the unusual pattern of resistance to six antimicrobial agents.
Nasopharyngeal flora in HIV seropositive men who have sex with men.
Oro-genital sex, usually without barrier protection, is common among HIV infected men who have sex with men and appears to be associated with increased meningococcal carriage but is autonomous to candida species isolation.

Sexual orientation and oro-genital contact influences both meningococcal and pharyngeal yeast isolation and should be considered when interpreting pharynGEal culture results.

In vitro activity of selected antimicrobial agents against penicillinase producing Neisseria gonorrhoeae (PPNG) and non-PPNG strains.
Results showed that all the cephalosporins used in this study had good in vitro activity against both PPNG and non-PPNG strains, and ceftriaxone had the lowest MICs.
