| an outbreak of psittacosis in a boys' boarding school. | in 1980, an outbreak of a mild illness involving twenty pupils and four adults in a boys' boarding school was identified serologically as psittacosis. intensive epidemiological investigations did not uncover the source. it is suggested either that sources of chlamydia other than avian exist, which may produce a milder illness than the avian type, or that human-to-human spread of a mild form of chlamydiosis occurs. | 1984 | 6736642 |
| chlamydia infection in ducks: preliminary communication. | chlamydia psittaci was isolated from cloacal swab pools from ducks in processing plants, and from cloacal and conjunctival swab pools from ducks on farms, in a small proportion of the samples examined. these isolates were difficult to passage. this difficulty was partly overcome by the use of emetine as the cell growth inhibitor. the direct complement fixation (cf) test was modified for testing duck sera by using complement at the los dose of 1.5 units. by this method, positive titres were demon ... | 1982 | 7069695 |
| prevalence of antichlamydial antibody in london blood donors. | the prevalence of type-specific antichlamydial antibody in a population of blood donors in london was studied using a microimmunofluorescence test. twenty-six (17%) of 150 women and 38 (26%) of 150 men had antichlamydial antibody (igg at greater than or equal to 1/16 or igm greater than or equal to 1/8 or both). of these, five (3%) women had one (0.75%) man had this antibody directed against chlamydia trachomatis serotypes d-k, responsible for genital infections, and one man had antibody to chla ... | 1980 | 7448582 |
| respiratory chlamydia: the management of an outbreak. | this investigation was undertaken in response to the occurrence of nine cases of respiratory chlamydial infection in 8 months within the district of dudley. all nine cases of respiratory chlamydia were due to chlamydia psittaci, not chlamydia pneumoniae. five cases had avian exposure, but no other aetiological factors were identified. faecal specimens were obtained from only two of the implicated birds and were negative. two local aviaries were identified as sources of implicated birds. the two ... | 1995 | 7597134 |
| chlamydial infection of the respiratory tract. | chlamydial infection of the human respiratory tract was first described over 100 years ago, when outbreaks of psittacosis were linked to imported pet birds. the causative organism was identified subsequently as chlamydia psittaci. however, c. pneumoniae, has also been recognised recently as an important cause of human respiratory tract infection. approximately 300 cases of human chlamydial respiratory tract infection are reported to cdsc each year, mainly in adults aged 15 to 44 years. a prospec ... | 1993 | 7693170 |
| antibodies to chlamydia species in patients attending a genitourinary clinic and the impact of antibodies to c. pneumoniae and c. psittaci on the sensitivity and the specificity of c. trachomatis serology tests. | in a retrospective study, the prevalence of antibodies to chlamydia trachomatis serovars d to k, c. pneumoniae, and c. psittaci in cases attending a genitourinary clinic was examined. blood samples were collected from 7,002 cases attending the clinic in doncaster, england between may 1983 and may 1990. sera from these samples were tested by a modified microimmunofluorescence test using panels of microdots of egg-grown, purified elementary bodies representing a pool of c. trachomatis d to k, a si ... | 1993 | 8503060 |
| epizootic bovine abortion in a dairy herd: characterization of a chlamydia psittaci isolate and antibody response. | a chlamydial agent was recovered from the placental cotyledons of an aborting cow from a 100-cow dairy herd in cumbria. immunoblotting analysis of purified elementary bodies of the isolate revealed a reactivity pattern typical of serotype i chlamydia psittaci strains. nucleotide sequencing of the major outer membrane protein (momp) gene further confirmed the isolate, ba1, as a serotype i strain. the sequence was identical to that of the type strain of ovine enzootic abortion, b577. in both the a ... | 1995 | 8605581 |
| isolation of faecal chlamydia from sheep in britain and their characterization by cultural properties. | faeces samples were taken per rectum from sheep on 26 farms in england and wales and examined for the presence of chlamydia by culture in mccoy cell monolayers. thirteen of the farms were known to have had abortion outbreaks associated with chlamydia psittaci (enzootic abortion) and 13 were free of this infection. the chlamydia isolated were characterized by cultural techniques. chlamydia were isolated from the faeces of lambs on all 26 farms and the prevalence of infection varied form 5-50% on ... | 1997 | 9232119 |
| zoonotic and viral infection in fetal loss after 12 weeks. | one hundred and thirty-six women from an urban, rural and farming community were recruited to a study of infectious causes of midtrimester miscarriage (n = 85), stillbirth (n = 32), or termination for developmental (n = 17) or chromosomal (n = 2) abnormalities. no woman had evidence of acute infection with toxoplasma, listeria, leptospira or chlamydia psittaci (ovine enzootic abortion). one woman had midtrimester miscarriage associated with primary cytomegolovirus infection and five women had ev ... | 1997 | 9255087 |
| an investigation into the role of chlamydophila spp. in bovine upper respiratory tract disease. | an outbreak of upper respiratory tract disease was investigated in a group of 17 housed home-bred calves on a mixed dairy, beef and sheep farm in devon. conjunctival swabs were collected and tested for chlamydophila spp. dna using a pcr test that detects chlamydophila abortus and chlamydophila psittaci. six of the calves tested gave a positive result. further epidemiological observations and laboratory testing indicated that the adult dairy cows, from which the affected calves originated, were t ... | 2006 | 16624729 |
| ten years of viral and non-bacterial serology in adults with cystic fibrosis. | viral infections are associated with pulmonary exacerbations in children with cystic fibrosis (cf), but few studies have addressed the frequency in adults. this paper investigates the frequency and impact of viral infections in adults with cf receiving intravenous antibiotics. pre- and post-treatment spirometry, inflammatory markers and antibody titres against influenza a, influenza b, adenovirus, respiratory syncytial virus, mycoplasma pneumoniae, chlamydia psittaci, and coxiella burnetti were ... | 2008 | 17352838 |
