gastrointestinal parasitism of iowa coyotes in relation to age.taenia sp., physaloptera sp., ancylostoma caninum, toxascaris leonina, and/or trichuris vulpis were recovered from gastrointestinal tracts of 141 and 144 (97.9%) coyotes ranging from 1/2 to 8 1/2 years of age. ancylostoma caninum exhibited a significant decline in both prevalence and mean number per coyote with increasing age of the host. taenia sp. appeared with consistently high prevalence in all age classes. physaloptera sp. and t. leonina showed general reductions in prevalence in all age cl ...1978641673
gastrointestinal helminths in dogs from a humane shelter in indiana.between january 1975 and august 1976, the alimentary tracts of 104 euthanatized dogs from a humane shelter in tippecanoe county, indiana, were examined to determine the prevalence of gastrointestinal helminths. the survey was restricted to dogs greater than 1 year old. their average age was estimated at approximately 2 years. parasitism was detected in 86.5% of the dogs examined. ancylostoma caninum was found most often (58.7%), followed by trichuris vulpis (51.9%), taenia sp (31.7%), toxocara c ...1978721684
visceral larva migrans and alveolar hydatid disease. dangers real or imagined.for both visceral larva migrans and alveolar hydatid diseases, it is the feces of companion animals that are the primary source of human infection. clearly, whatever is done to reduce this form of environmental contamination and the prevalence of the parasites' infective stages will help to protect the health of the human population in the united states and canada, particularly the children. very important are appropriate anthelmintic treatment programs, especially for t. canis, and proper contr ...1978356405
[research on intestinal parasitic diseases in dogs of the city of rome].a survey on the diffusion of intestinal parasites of dogs in the town of rome. the results of a survey on the diffusion of cestodes and nematodes in a hundred dogs in rome are reported. the dogs were subjected to fecal examinations --- using both the flottation method and the mcmaster method -- and to the post-mortem examination of the intestine. at post-mortem examination 25 dogs were found parasitized by one or more species of nematodes, 19 by one or more species of cestodes and 12 both by ces ...1977754133
toxocara infection in pigs. the use of indirect fluorescent antibody tests and an in vitro larval precipitate test for detecting specific antibodies.an in vitro larval precipitate test using second-stage toxocara canis larvae and an indirect fluorescent antibody (ifa) test employing cuticles of t. canis larvae as antigen were evaluated using antisera produced in pigs experimentally infected with t. canis, t. cati, ascaris suum, toxascaris leonina and parascaris equorum. the former test was both specific and sensitive and is suggested as a reliable and simple method of detecting toxocara antibodies in pigs. the latter test was considered unsu ...1977328560
a survey of patent nematode infestations in dogs.a survey of faecal samples taken from 1000 suburban dogs revealed an infestation of 7-2 per cent toxocara canis, 2-7 per cent toxascaris leonina, 1-3 per cent trichuris vulpis and 1-3 per cent uncinaria stenocephala. the faecal material examined was obtained per rectum from well cared-for pet dogs resident in an area of north-west suburban london. the age of the dogs examined, both male and female, ranged from three weeks to 18 years. the clinical picture of the dogs affected by ascariasis and i ...1977860384
coccidia and intestinal nematodes of east central illinois cats.in a fecal examination survey (1975-1976) of 217 cats from laboratory colonies, a humane society shelter, and homes in east central illinois, toxocara mystax eggs were found in 32%, toxascaris leonina eggs in 6%, ancylostoma eggs in 9%, capillaria eggs in 4%, isospora felis oocysts in 23%, isospora rivolta oocysts in 24%, and toxoplasma or besnoitia oocysts in 1%. the laboratory and humane shelter cats were the most heavily infected. isospora felis and i rivolta could not be transmitted to 2 pup ...1977873847
