| a longitudinal study of mycoplasma pneumoniae: infections in navy recruits by isolation and seroepidemiology. | a longitudinal serologic study of m. pneumoniae infections in two recruit training centers with grossly different climates showed that the frequency of this infection peaks in the late summer-early fall and to a lesser degree in the spring at both training centers. seroconversions (four-fold or greater increase in titer) were as high as 45-57% in some recruit companies during the late summer peak. m. pneumoniae isolations from men admitted to the dispensary or hospital with pneumonia during the ... | 1976 | 984030 |

| evaluation of diagnostic procedures to detect mycoplasma synoviae in commercial multiplier-breeder farms and commercial hatcheries in florida. | sera from 5325 chickens representing 71 commercial poultry flocks were tested for mycoplasma synoviae (ms) using standard national poultry improvement program (npip) testing guidelines. based on the npip guidelines, only sera (n = 195) from flocks that test positive by specific plate agglutination (spa) were submitted for additional confirmatory tests. flocks from three multihouse farms were identified as seropositive for ms and confirmed by culture and polymerase chain reaction (pcr). serum sam ... | 1996 | 8980809 |
| classification of new phytoplasmas associated with diseases of strawberry in florida, based on analysis of 16s rrna and ribosomal protein gene operon sequences. | strawberry plants exhibiting symptoms of stunting and abnormally small leaves were observed in production fields in central florida, usa. since the symptoms were suggestive of phytoplasma infection, plants were assayed for presence of phytoplasma by pcr amplification of 16s rdna and ribosomal protein (rp) gene sequences. amplification of phytoplasma-specific dna sequences by pcr indicated infection of the diseased strawberry plants by phytoplasmas. rflp analyses of amplified 16s rdna revealed th ... | 1998 | 9542097 |
| mycoplasma sturni from blue jays and northern mockingbirds with conjunctivitis in florida. | northern mockingbirds (mimus polyglottos) and blue jays (cyanocitta cristata) in a florida (usa) wildlife care facility developed clinical signs and gross lesions suggestive of the ongoing outbreak of mycoplasma gallisepticum (mg) conjunctivitis in house finches (carpodacus mexicanus) and american goldfinches (carduelis tristis). mycoplasmal organisms were cultured from conjunctival/corneal swabs of birds with sinusitis, conjunctivitis, and/or epiphora. all of the isolates tested were identified ... | 1998 | 9577796 |
| pathology of upper respiratory tract disease of gopher tortoises in florida. | between august 1993 and september 1995, 24 gopher tortoises (gopherus polyphemus) were received for pathological evaluations from various locations in florida (usa). all tortoises were examined for clinical signs of upper respiratory tract disease (urtd) including nasal and ocular discharge, palpebral edema, and conjunctivitis. of the 24 tortoises, 10 had current or previously observed clinical signs of urtd and 14 did not. a blood sample was drawn for detection of anti-mycoplasma antibodies by ... | 2000 | 10813609 |
| morbidity and mortality associated with a new mycoplasma species from captive american alligators (alligator mississippiensis). | nine of 74 american alligators (alligator mississippiensis) from a captive florida herd of 3-4-m-long, 200-350-kg, adult males greater than 30 yr of age died within a 10-day period during 1995. nonspecific clinical signs included anorexia, lethargy, muscle weakness, paraparesis, bilateral white ocular discharge, and various degrees of periocular, facial, cervical, and limb edema. pneumonia, pericarditis, and arthritis were found on postmortem evaluation of the spontaneously dead and euthanatized ... | 2000 | 11237136 |
| mycoplasma alligatoris sp. nov., from american alligators. | mycoplasmas were isolated from multiple tissues of diseased american alligators (alligator mississippiensis). this paper presents biochemical, serological and molecular genetic characterizations of a lethal pathogen of alligators for which the name mycoplasma alligatoris sp. nov. is proposed. the type strain is a21jp2t (atcc 700619t). | 2001 | 11321088 |
| prevalence of infectious diseases in feral cats in northern florida. | objectives of this study were to determine prevalence of infection in feral cats in northern florida with a select group of infectious organisms and to determine risk factors for infection. blood samples or sera from 553 cats were tested with a panel of antibody, antigen or pcr assays. male cats were at higher risk for fiv, mycoplasma haemofelis, and m. haemominutum. infection with either felv or fiv was associated with increased risk for coinfection with the other retrovirus, m. haemofelis, or ... | 2004 | 15363760 |
| pigeon paramyxovirus: association with common avian pathogens in chickens and serologic survey in wild birds. | pigeon paramyxovirus-1 (ppmv-1) was isolated from pigeons from east-central alabama and used in association with chicken anemia virus (cav), infectious bursal disease virus (ibdv), or finch mycoplasma gallisepticum (mg) in specific-pathogen-free chickens to assess dinical disease and pathology. ppmv-1 infection in all groups was conducted at day 10 of age via the ocular route. the low passage ppmv-1 isolate was inoculated into chickens in different groups at 10 days post-cav infection, 6 days po ... | 2005 | 15839419 |
| seroprevalence of mycoplasma alligatoris among free-ranging alligators (alligator mississippiensis) in florida--2003. | mycoplasma alligatoris causes acute lethal infection of alligators (alligator mississippiensis). the objective of this study was to assess the current seroprevalence of m. alligatoris among free-ranging, juvenile and subadult alligators in florida. thirty-two of 592 (5.4%) plasma samples from alligators at 12 of 20 sites (60%) in april and october 2003 were tested seropositive (titer 1: > or = 32) by enzyme-linked immunosorbent assay for anti-m. alligatoris antibodies. these results show that al ... | 2005 | 17323582 |
| mycoplasmosis in green iguanas (iguana iguana). | mycoplasma iguanae was the suspected etiology of spinal disease in feral iguanas (iguana iguana) from florida. in an experimental infection study, juvenile iguanas were inoculated with m. iguanae intravenously or by instillation into the nares. blood samples obtained at intervals postinoculation were all culture negative for mycoplasma. gross anatomic and histologic findings at necropsy 12 wk postinoculation were unremarkable. mycoplasmas were cultured in high numbers from the posterior choanae ... | 2007 | 17679524 |
| upper respiratory tract disease, force of infection, and effects on survival of gopher tortoises. | upper respiratory tract disease (urtd) caused by mycoplasma agassizii has been hypothesized to contribute to the decline of some wild populations of gopher tortoises (gopherus polyphemus). however, the force of infection (foi) and the effect of urtd on survival in free-ranging tortoise populations remain unknown. using four years (2003-2006) of mark-recapture and epidemiological data collected from 10 populations of gopher tortoises in central florida, usa, we estimated the foi (probability per ... | 2009 | 19425439 |
| social behavior drives the dynamics of respiratory disease in threatened tortoises. | since the early 1990s, morbidity and mortality in tortoise populations have been associated with a transmissible, mycoplasmal upper respiratory tract disease (urtd). although the etiology, transmission, and diagnosis of urtd have been extensively studied, little is known about the dynamics of disease transmission in free-ranging tortoise populations. to understand the transmission dynamics of mycoplasma agassizii, the primary etiological agent of urtd in wild tortoise populations, we studied 11 ... | 2010 | 20503858 |
| effects of mycoplasmal upper respiratory tract disease on morbidity and mortality of gopher tortoises in northern and central florida. | gopher tortoise (gopherus polyphemus) populations on four tracts of public lands in northern and central florida were studied from 1998 to 2001 to assess the effects of mycoplasmal upper respiratory tract disease (urtd). adult gopher tortoises (n=205) were marked for identification, serum and nasal flush samples were obtained for mycoplasmal diagnostic assays, and clinical signs of urtd (nasal discharge, ocular discharge, palpebral edema, and conjunctivitis) were evaluated. a subset of tortoises ... | 2010 | 20688675 |
