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

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

Ostertagia ostertagi, calves (nat. and exper.), type I ostertagiasis, assay of lymphocyte reactivity to O. ostertagi L3 antigen and phytohemagglutinin, possible lack of genus specificity to antigen shown by reaction using lymphocytes from Cooperia punctata-infected calves, kinetics of lymphocyte reactivity showed transient nonspecific suppression of cell-mediated immune responses during prepatent periods of type I ostertagiasis, immunosuppression phenomenon may have role in O. ostertagi pathogenesis and development of immunity

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

monoclonal antibodies derived from Trichinella spiralis-infected mice reacted with other swine parasites, one monoclonal antibody recognized antigenic determinant specific to T. spiralis, isolation of this antigen by monoclonal antibody-affinity chromatography, use of antigen in enzyme-linked immunosorbent assay eliminated false-positive reactions with serum of healthy swine and detected all pigs infected with T. spiralis

Eimeria spp., calves (exper.) treated with lasalocid (Bovatec) or decoquinate (Deccox) and premunized did not develop diarrhea, calves premunized but not treated were no more resistant to challenge than nonpremunized calves, premunization alone cannot be expected to prevent coccidiosis when animals are exposed to large numbers of oocysts
