acute Sarcocystis cruzi infection in calves (exper.), hematologic studies support claim that anemia is an extravascular hemolytic event, probably with immunologic basis; coagulation studies indicate that endothelial S. cruzi schizonts may cause endothelial damage, resulting in coagulation abnormalities that include disseminated intravascular coagulation

tick infestations did not cause suppressed immune responses to Anaplasma marginale vaccination in calves, anaplasmosis did not prevent calves from developing resistance to tick reinfestation which was accompanied by immediate hypersensitivity reactions against homologous tick extracts, Dermacentor albipictus did not seem to share common antigenic determinants with Boophilus microplus

helminths of naturally infected dogs and cats, effect of febantel/praziquantel paste

Ostertagia ostertagi, beef calves (exper.), levamisole gel formulation evaluated for efficacy, safety, and residues

Fasciola hepatica, natural infections of cattle surveyed by enzyme-linked immunosorbent assay (ELISA), results compared with those obtained by fecal examination, advantages and limitations of ELISA for diagnosis: Washington

Dirofilaria immitis, dogs, histopathological study of host response and fate of microfilariae after treatment with ivermectin

Baylisascaris procyonis, experimental infection of domestic pigs with eggs from raccoons, B. procyonis will undergo limited migration in swine and can produce typical white spots in the liver, larvae were killed by cellular reactions in the intestinal wall and liver, no somatic migration or CNS disease occurred after infection

equine feces containing 325 strongyle eggs/g of feces were buried at different depths below pasture surface in sandy clay loam soil, greatest distance of migration of infective larvae was 20 cm which occurred 31 days after feces were buried but number of larvae reaching herbage from this depth represented only 0.0004% of the eggs initially buried: Texas

evaluation of a Toxocara canis blastogenesis assay with peripheral mononuclear cells in Macaca fascicularis with induced T. canis infections and in humans with serologically confirmed visceral larva migrans (VLM), questionable sensitivity, difficulty, expense, and time associated with this technique do not make it suited for confirming a clinical diagnosis of VLM

Dirofilaria immitis, dogs, enzyme linked immunosorbent assay used in combination with radiographic examination, Knott test, blood cell counts, and fecal examinations to study seroepizootiology of canine heartworm infection and to investigate the influence of several host and environmental factors (age, sex, living conditions, breed, hair coat length) and chemoprophylaxis (diethylcarbamazine) on serological patterns in dogs; other nematodes also identified
