A morphologic and molecular epidemiologic investigation was conducted on a captive African black-footed penguin (Spheniscus demersus) colony with a history of Plasmodium infections at La Palmyre Zoo (France). Each penguin received 12.5 mg of pyrimethamine twice a week as a prophylaxis every year from April to November. Although Plasmodium parasites were not(More)
Determinants of infertility were studied in 340 women in Eastern Gabon, an area situated in the "infertility belt" of Central Africa. Fallopian tube occlusion was diagnosed in 82.8% of cases, showing the importance of infection-related causes. Women with tubal occlusion did not differ significantly from women with normal tubes in obstetrical history or(More)
Prevalence of Chlamydia trachomatis antibodies was studied in infertile women with and without tubal obstruction, and in a control group of pregnant women in a Central-African country with a high infertility rate. In comparison with the control group, tubal infertility patients were significantly more likely to have serum antibodies of 1:64 or greater with(More)
Samples from 218 men with urethritis, 517 women with pelvic pain or pelvic pain and vaginal discharge, 218 women consulting for infertility, and 598 postpartal women were screened for Chlamydia trachomatis by culture and direct immunofluorescence. Chlamydiae were detected in 18% (39/218) of the men, 18% (45/252) of women with vaginal discharge, 14% (38/265)(More)
A questionnaire was sent to 39 European institutions holding greater kudus (Tragelaphus strepsiceros), in order to determine the causes of captive greater kudu mortality. All reported macroscopic lesions and histopathologic observations, as well as other information regarding individuals that died, were analyzed to determine the most affected body systems(More)
Of 35 women with acute salpingitis on laparoscopy, 86% had chlamydial antibodies at a titre of 1/16 or higher and 49% at a titre of 1/512 or higher. Geometric mean titres of chlamydial antibodies correlated significantly with a laparoscopic observation of chronic salpingitis (p less than 0.001), with a history of infertility (p less than 0.05), and with(More)
The objective of this study was to evaluate the effects of stress (as measured by total heterophil + eosinophil counts [THECs] and plasma corticosterone [PC] levels) on plasma protein electrophoresis (PPE) in two Anseriform species. Ten red-breasted geese ( Branta ruficollis ) and eight Hawaiian geese (Branta sandvicensis) were received into quarantine at(More)
Reproductive tract tumours, specifically leiomyoma, are commonly found in female rhinoceroses. Similar to humans, tumour growth in rhinoceroses is thought to be sex hormone dependent. Tumours can form and expand from the onset of ovarian activity at puberty until the cessation of sex-steroid influences at senescence. Extensive tumour growth results in(More)
The current report describes the temporary regression, due to intensive symptomatic treatment, of ulcerative skin lesions caused by squamous cell carcinoma in a white rhinoceros. A captive, 40-yr-old southern white rhinoceros (Ceratotherium simum simum) developed profound, ulcerative skin lesions on the pads of both hind feet. At the peak of the disease, at(More)
