effect of immunization of cats with isospora felis and bcg on immunity to reexcretion of toxoplasma gondii oocysts.the effect of pretreatment with isospora felis and bacillus calmette-guérin (bcg) on the reexcretion of toxoplasma gondii oocysts was studied in 16 coccidia-free cats. the following conclusions were drawn: (a) chronically t. gondii-infected cats reexcreted t. gondii oocysts after superinfection with i. felis, and this reexcretion was prevented in cats infected with i. felis before t. gondii infection. (b) administration of bcg before toxoplasma infection had no apparent effect on the outcome of ...1978364044

isolation of tissue cysts of toxoplasma, isospora, hammondia and sarcocystis from camel (camelus dromedarius) meat in saudi arabia.meat samples were collected from the oesophagus and tongue of 38 camels slaughtered at the main abattoir of al-ahsa city, saudi arabia. five cats and three dogs, conventionally reared and coccidia-free, were caged individually in steel cages. camel meat was pooled, minced and fed to four cats and two dogs. one cat and one dog were not fed meat and were kept as noninfected controls. faecal samples from infected and control animals were examined daily for a period of 2 months after feeding the mea ...19958533274

contamination of soil with parasite eggs in surabaya, indonesia.soil was examined for contamination by parasite eggs in surabaya indonesia. surveys were carried out on three occassion; july, 1993 (dry season), march, 1994 (rainy season), and august, 1994 (dry season). throughout the study, five species of nematode eggs (ascaris lumbricoides, toxocara cati, trichuris trichiura, physaloptera sp, capillaria sp), two species of cestode eggs (hymenolepis diminuta, spirometra erinacei), and one species of protozoa oocyst (isospora felis) were detected. the contami ...19959139385

enzyme-linked immunosorbent assay for the detection of cryptosporidium parvum igg in the serum of cats.the objective was to develop an enzyme-linked immunosorbent assay (elisa) for the detection of cryptosporidium parvum igg in the serum of cats. the elisa was an indirect elisa using soluble c. parvum oocyst antigens and a peroxidase-labeled anti-feline igg secondary antibody. sera from cats with toxocara felis, giardia spp., aelurostrongylus abstrusus, isospora felis, isospora rivolta, toxoplasma gondii, or taenia spp. infections were assayed in specificity studies. following optimization, the e ...19979379309

phylogenetic analysis of coccidia based on 18s rdna sequence comparison indicates that isospora is most closely related to toxoplasma and neospora.the phylogenetic relationships and taxonomic affinities of coccidia with isosporan-type oocysts have been unclear as overlapping characters, recently discovered life cycle features, and even recently discovered taxa, continue to be incorporated into biological classifications of the group. we determined the full or partial 18s ribosomal rna gene sequences of three mammalian isospora spp., isospora felis, isospora ohioensis and isospora suis, and a sarcocystis sp. of a rattlesnake, and used these ...19989561772

effects of sequence alignment and structural domains of ribosomal dna on phylogeny reconstruction for the protozoan family sarcocystidae.finding correct species relationships using phylogeny reconstruction based on molecular data is dependent on several empirical and technical factors. these include the choice of dna sequence from which phylogeny is to be inferred, the establishment of character homology within a sequence alignment, and the phylogeny algorithm used. nevertheless, sequencing and phylogeny tools provide a way of testing certain hypotheses regarding the relationship among the organisms for which phenotypic character ...200011110900
