| experimental transmission of gastro-intestinal nematodes between sheep (ovis aries) and thomson's gazelles (gazella thomsonii). | experimental cross-transmission of gastro-intestinal nematodes between merino sheep (ovis aries) and thomson's gazelles (gazella thomsonii) from similar but separate grazing habitats in kenya was studied. cross-transmission did occur with some species but the faecal egg counts of sheep were higher than the gazelles' following infection with larvae isolated from either sheep or gazelles. of the 11 gastro-intestinal nematodes which became established in gazelles following infection with larvae cul ... | 1979 | 501844 |
| nematodes parasitizing domestic ruminants in afghanistan. | a total of 12 nematode species were determined in the collection recovered from domestic ruminants in afghanistan. ten of them were found for the first time in this region: trichocephalus globulosus, trichostrongylus probolurus, cooperia bisonis, nematodirus spathiger, n. abnormalis, thelazia rhodesi, bunostomum phlebotomum, haemonchus contortus, dictyocaulus filaria and oesophagostomum radiatum. morphological and metrical characteristics of t. globulosus, t. skrjabini and c. bisonis, based on o ... | 1976 | 1034588 |
| seasonal fluctuations of gastrointestinal helminths of camels in kuwait. | over a period of 1 year, from may 1982 to april 1983, the gastrointestinal tracts of 240 camels were examined for the presence of parasitic helminths. the study quantifies the prevalence of gastrointestinal helminths and the seasonal fluctuations in intestinal worm burdens and faecal worm egg counts. among the three species of cestodes and eight species of nematodes which were recorded for the first time from kuwait, trichostrongylus probolurus (93.8%), t. colubriformis (34.2%) and stilesia vitt ... | 1988 | 3388739 |
| the ecology of animal parasitic nematodes in endemic areas of jos, nigeria. | a survey involving 3418 faecal samples collected from three areas of heavy human and animal activities in jos, nigeria showed that 2354 (68.9%) of the samples harboured various parasitic nematodes of man and animals. altogether, twelve species of parasitic nematodes were encountered. five of these, namely: ascaris lumbricoides, ancylostoma duodenale, necator americanus, trichuris trichiura and strongyloides stercoralis infect man while five others: trichostrongylus probolurus, t. colubriformis, ... | 1993 | 8334456 |
| common secondary structures for the second internal transcribed spacer pre-rrna of two subfamilies of trichostrongylid nematodes. | sequences of the second internal transcribed spacer ribosomal dna for the parasitic trichostrongylid nematodes trichostrongylus probolurus, trichostrongylus rugatus and camelostrongylus mentulatus were compared with previously published sequences for five other species within the genus trichostrongylus. the secondary structures of the second internal transcribed spacer pre-rrna for these nematodes were predicted using an energy minimisation method. the results indicate that a common secondary st ... | 1998 | 9846614 |
| abomasal and small intestinal nematodes from captive gazelles in spain. | the abomasal and small intestinal helminth fauna of three species of captive gazelles (gazella dama mhorr, g. cuvieri and g. dorcas neglecta) kept in captivity in almería (southeast spain) have been studied, and the following species were identified: nematodirus spathiger, n. filicollis, n. helvetianus, camelostrongylus mentulatus, trichostrongylus vitrinus, t. probolurus, t. colubriformis, ostertagia ostertagi, o. harrisi, teladorsagia (ostertagia) circumcincta, and t. (ostertagia) davtiani. ca ... | 2001 | 11818055 |
| epidemiological studies on gastrointestinal helminths of dromedary (camelus dromedarius) in semi-arid lands of eastern ethiopia. | a total of 752 dromedaries were examined and 75% were found to be harbouring nematode eggs. the mean epg was 1831 and the range was from 100 to 21,200. the prevalence rates in the four-age groups examined were 59.6% (3-7 years), 72.4% (8-12 years), 76.1% (13-17 years) and 83.9% (18-22 years). the prevalence rate for females and males were 77.6 and 64.8%, respectively and for long dry, short rainy, short dry and long rainy seasons were 66, 80, 69 and 82.6%, respectively. the mean epg of faeces wa ... | 2002 | 11900928 |
