To the Editor: In April 2009, a 47-year-old woman in Saint-Jeannet in southern France reported stomach aches, abdominal bloating, and occasional diarrhea. Blood analyses found an increased eosinophil level (8,800 cells/mm 3), which represented 52% of 16,900 leukocytes/mm 3. Parasitologic examinations for helminths were conducted with 6 fecal specimens obtained during June 9– July 2, 2009. Analy...

Soon after 12-week old suckling lambs reached a peak infestation of Nematodirus resistance developed, worm burdens falling by 43.1-97.5% in 18 week and 11-month old sheep respectively. Both Teladorsagia (syn. Ostertagia) and Trichostrongylus reached a peak geometric mean (G) of 18,099 and 3,278 worms on 02 December 1987 in weaners 5-6 months old. Within 6 weeks-6 months of sheep grazing on safe...

In order to characterize the epidemiology of sheep gastrointestinal nematodes in organic and conventional flocks in Canada, a longitudinal study was carried out from May 2006 to March 2008 on 32 purposively selected farms in Ontario (ON) and Quebec (QC): 8 certified organic (CO), 16 non-certified organic (NCO), and 8 conventional (C) farms. On each farm, 10 ewes and 10 female lambs were selecte...

All of the 111 baboons examined from the Loskop Dam, Suikerbosrand and Scrutton Nature Reserves and the Sabie-Tweefontein Forest Reserve were infested with helminths of the digestive tract. The helminths recovered were Bertiella studeri, Enterobius vermicularis, Oesophagostomum bifurcum, Physaloptera caucasica, Streptopharagus pigmentatus, Strongyloides fülleborni, Trichostrongylus falculatus, ...

background: the aim of this study was to verify the occurrence of intestinal parasitic infections in human immunodeficiency virus (hiv)/acquired immunodeficiency syndrome (aids) patients in iran in comparison with non-hiv individuals. methods: a total of hiv+/aids patients (group i) and 1220 clinically healthy individuals (group ii) were submitted to coproparasitological examination from 2003 t...

A pregnant female Cape giraffe (Giraffa camelopardalis giraffa) died from an unknown cause in the Aitana Zoo, Alicante, Spain. Neither clinical signs nor macroscopic lesions were observed at necropsy. The alimentary tract was removed and examined for parasites. A total of 2 724 nematodes were found, including Camelostrongylus mentulatus, Trichostrongylus axei, Ostertagia ostertagi, Teladorsagia...

A total of 145 scrub hares from three localities in the Kruger National Park were examined for helminths: 124 at Skukuza, 15 at Shingwedzi, and three each at Pretoriuskop and Pafuri. Trichostrongylus deflexus was the most prevalent and most abundant nematode, and was collected from hares from all four localities. Trichostrongylus falculatus was present in three localities. Trichostrongylus thom...

Two doses of infective larvae of 20 000 Trichostrongylus axei, dosed to Merino lambs at an interval of 14 days and subsequently challenged with Ostertagia circumcincta, caused a significant reduction (P less than 0.01) in the establishment of 5th and adult stages of the latter. T. axei was unable to protect Merino sheep against homologous challenge nor was Haemonchus contortus a successful vacc...
