| isolation of mycoplasma gallopavonis from free-ranging wild turkeys in coastal north carolina seropositive and culture-negative for mycoplasma gallisepticum. | serum samples and choanal cleft swabs were collected from livetrapped and hunter killed wild turkeys (meleagris gallopavo) from martin and bertie counties, north carolina (usa). sera were tested for antibodies to mycoplasma gallisepticum, mycoplasma synoviae and mycoplasma meleagridis by hemagglutination inhibition (hi). sera from 33% (five of 15) of livetrapped turkeys were positive for antibodies to m. gallisepticum by hi, and all were negative for antibodies to m. synoviae and m. meleagridis. ... | 1992 | 1548788 |
| the prevalence of mycoplasma pneumoniae in ambulatory patients with nonstreptococcal sore throat. | several studies have implicated mycoplasma pneumoniae as an important cause of nonstreptococcal pharyngitis in certain clinical settings. this study was performed to determine the prevalence of m. pneumoniae infection in family practice patients with sore throats and to identify patient characteristics predictive of this infection. m. pneumoniae throat cultures were obtained from 419 patients aged five years or older who were seen in one of four family practice offices with a complaint of sore t ... | 1991 | 1903744 |
| risk factors for haemobartonella felis infection in cats. | a seroepidemiologic survey for haemobartonella felis infection in cats of wake county, nc was undertaken. to help assess risk factors, cat owners completed a 10-item questionnaire. additionally, blood samples were obtained for determination of h felis presence, felv infection, and anemia. prevalence rates for h felis presence were as follows: all cats, 4.9% (6/123); healthy cats, 3.6% (3/83); and ill cats, 7.5% (3/40). the estimated relative risk for haemobartonellosis was also increased in cats ... | 1990 | 2295559 |

| clinical mycoplasma gallisepticum infection in multiplier breeder and meat turkeys caused by f strain: identification by sodium dodecyl sulfate-polyacrylamide gel electrophoresis, restriction endonuclease analysis, and the polymerase chain reaction. | in february 1991, a flock of north carolina multiplier breeder turkeys experienced respiratory signs, sinusitis, airsacculitis, and increased mortality. mycoplasma gallisepticum (mg) was isolated, and appropriate control measures were initiated. ultimately, this outbreak involved several breeder flocks of an integrated turkey production company before the last infected flock was identified in may 1991. during this time, mg was also isolated from a flock of commercial layer-type chickens raised a ... | 1993 | 8257382 |

| epidemic pneumonia in university students. | longitudinal surveillance of pneumonia in a university student health service was conducted from 1965-1971 and 1984-1987. of 104 pneumonia cases documented by chest x-ray, only six were presumed to have bacterial etiology; the remaining 98 were characteristic of atypical pneumonia syndrome. mycoplasma pneumoniae was the etiology in 51% of the pneumonias in the 1960s and 13% in 1984-1987. pneumonia incidence was highest in the fall semester in seven of 11 years studied. annual incidence followed ... | 1989 | 2514160 |
| an outbreak of mycoplasma synoviae infection in north carolina turkeys: comparison of isolates by sodium dodecyl sulfate-polyacrylamide gel electrophoresis and restriction endonuclease analysis. | mycoplasma synoviae (ms) isolates made in 1988-89 from turkey flocks in north carolina, missouri, and ontario, canada, were compared with each other and ms reference strains (wvu-1853, f10-2as, neb-3s, and k1968) by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (sds-page) of cell proteins and restriction endonuclease analysis (rea) of dna. sds-page and rea indicated considerable homology among ms reference strains and recent field isolates. however, sufficient differences were resolv ... | 1992 | 1329712 |
| respiratory infections due to mycoplasma pneumoniae in infants and children. | systematic monitoring of infants and children in a day-care center revealed infection with mycoplasma pneumoniae to be more common than expected. most of these infections were asymptomatic (74%) or associated with mild, nonspecific coryza and cough. infected children ranged in age from 2 months to 8 years. complement-fixing and growth-inhibiting antibodies in serum tended to wane rapidly and reinfection was detected in five children after one and one-half to 3 years. in vitro lymphocyte studies ... | 1975 | 1143973 |
| the etiologic and epidemiologic spectrum of bronchiolitis in pediatric practice. | to develop a broad understanding of the causes and patterns of occurrence of wheezing associated respiratory infections, we analyzed data from an 11-year study of acute lower respiratory illness in a pediatric practice. although half of the wari occurred in children less than 2 years of age, wheezing continued to be observed in 19% of children greater than 9 years of age who had lower respiratory illness. males experienced lri 1.25 times more often than did females; the relative risk of males fo ... | 1979 | 448557 |
| acute respiratory disease of university students with special reference to the etiologic role of herpesvirus hominis. | infections with herpesvirus hominis type 1 were associated with 11.5% of acute respiratory illnesses of university students who were admitted to the student infirmary over a 6-year period. over three-quarters of these infections were detected in students with pharyngitis or tonsillitis; 42% had ulcerated lesions on tonsils or posterior pharynx but only 11% had lesions in the anterior portion of the mouth or lips. almost all of the h. hominis infections were accompanied by significant rises in ne ... | 1975 | 164768 |
| mycoplasma genitalium detected by transcription-mediated amplification is associated with chlamydia trachomatis in adolescent women. | the clinical significance of mycoplasma genitalium (mg) infection in adolescent women is poorly understood. we compared the prevalence of mg with that of other sexually transmitted organisms such as chlamydia trachomatis (ct), neisseria gonorrhoeae (ng), and trichomonas vaginalis (tv) and assessed the associations of mg with sexual behaviors, genitourinary symptoms, physical and laboratory findings. | 2008 | 18490867 |

| fallout from the std epidemic: salpingitis, ectopic pregnancy, and infertility. | recent trends in sexually transmitted diseases (stds) in the u.s., and their bearing on pelvic inflammatory disease (pid) and infertility are evaluated. stds have increased 12-fold in the last decade, in comparison with a 200-fold rise in aids. while the total gonorrhea rate fell 10% last year, the incidence of gonorrhea resistant to penicillin or to all drugs is mounting. syphilis increased 25% last year, probably because resources for contact-tracing were devoted to hiv infection, be ... | 1989 | 12284994 |
| molecular epidemiologic investigations of mycoplasma gallisepticum conjunctivitis in songbirds by random amplified polymorphic dna analyses. | an ongoing outbreak of conjunctivitis in free-ranging house finches (carpodacus mexicanus) began in 1994 in the eastern united states. bacterial organisms identified as mycoplasma gallisepticum (mg) were isolated from lesions of infected birds. mg was also isolated from a blue jay (cyanocitta cristata) that contracted conjunctivitis after being housed in a cage previously occupied by house finches with conjunctivitis, and from free-ranging american goldfinches (carduelis tristis) in north caroli ... | 1997 | 9284386 |

| the epidemiology of tracheobronchitis in pediatric practice. | epidemiologic characteristics of childhood tracheobronchitis occurring over a 104-month period in chapel hill, nc, were ascertained and compared to those of other pediatric lower respiratory illness (lri) syndromes. tracheobronchitis accounted for 40% of all lri seen at the community's only pediatric practice. tracheobronchitis incidence was highest during the first two years of life, through the ratio of tracheobronchitis incidence to total lri incidence increased with age. a viral pathogen or ... | 1981 | 6797294 |
| an epornitic of mycoplasma gallisepticum in turkeys. | a major epornitic of mycoplasma gallisepticum occurred in the monroe, north carolina, area between january and june of 1983. the outbreak involved 304,000 turkeys of various ages, which were slaughtered in the eradication program at a cost of more than $550,000 to growers and poultry companies. an infected peafowl was the likely source of infection on the first farm. traffic between farms by growers and company personnel was theorized to be the means of further spread. | 1984 | 6487195 |
