| prevalence of six sexually transmitted disease agents among pregnant inner-city adolescents and pregnancy outcome. | 115 pregnant girls aged 13-17 years were investigated during the third trimester for endocervical infection with six sexually transmissible microorganisms. specimens from 21 patients destroyed the tissue cell monolayers for propagation of chlamydia trachomatis, but 11 were no longer toxic when recultured after freezing or with additional antimicrobial agents; trichomonas vaginalis was present in 76% of the toxic specimens. c trachomatis was recovered from 37% of 105 specimens. t vaginalis was re ... | 1984 | 6146874 |
| field investigation of mycoplasma gallisepticum infections in house finches (carpodacus mexicanus) from maryland and georgia. | a field study investigating the occurrence of mycoplasma gallisepticum (mg) in house finches (carpodacus mexicanus) was conducted in maryland and georgia. eighty-eight finches were captured and examined grossly and microscopically for mg-related conjunctivitis. serum samples were obtained for serum plate agglutination (spa) and hemagglutination inhibition (hi) testing. swabs from conjunctiva, sinus, and choanal cleft were inoculated into two mycoplasma broth media for culture and polymerase chai ... | 1996 | 8790883 |

| prospective study of respiratory infections at the u.s. naval academy. | midshipmen at the u.s. naval academy have recently suffered epidemics of upper respiratory tract infections. seeking to determine cause, in june 1998 we enrolled 1,243 (99.5%) of 1,249 new midshipmen (plebes) and followed them during their first 11 months of training. eighty-five plebes sought medical attention for acute respiratory disease. using culture, serologic studies, and polymerase chain reaction, considerable evidence for respiratory pathogen infection was found among the ill subjects: ... | 2001 | 11569436 |
| prevalence of bartonella species, haemoplasma species, ehrlichia species, anaplasma phagocytophilum, and neorickettsia risticii dna in the blood of cats and their fleas in the united states. | ctenocephalides felis were killed and collected from 92 cats in alabama, maryland, and texas. the fleas and blood from the corresponding cat were digested and assessed in polymerase chain reaction assays that amplify dna of ehrlichia species, anaplasma phagocytophilum, neorickettsia risticii, mycoplasma haemofelis, 'candidatus m haemominutum' and bartonella species. dna consistent with b henselae, b clarridgeiae, m haemofelis, or 'candidatus m haemominutum' was commonly amplified from cats (60.9 ... | 2006 | 16290092 |
| effect of sexually transmitted disease (std) coinfections on performance of three commercially available immunosorbent assays used for detection of herpes simplex virus type 2-specific antibody in men attending baltimore, maryland, std clinics. | two hundred seventy-nine serum samples from men attending sexually transmitted disease (std) clinics in baltimore, maryland, were tested for herpes simplex virus type 2 (hsv-2)-specific antibody by three immunosorbent glycoprotein g-2-based assays (the kalon, focus, and biokit assays). the results for all samples with positive results were confirmed by western blotting (91/279; 32.6% hsv-2 seroprevalence). all patients were also tested for chlamydia trachomatis, neisseria gonorrhoeae, trichomona ... | 2007 | 17913866 |
| a survey of rodent-borne pathogens carried by wild-caught norway rats: a potential threat to laboratory rodent colonies. | unintentional infection of laboratory rodents can compromise scientific research as well as the health of the animals and animal handlers. the source of contamination often is unknown, but may be introduced by wild rats from surrounding environments. to determine whether rats in baltimore, maryland, usa carry infectious agents commonly found in laboratory rodent colonies, we live-trapped 162 rats during 2005 to 2006 and screened them for a panel of viruses, bacteria and parasites. antibodies aga ... | 2008 | 18348770 |
