| intestinal nematodes of white-tailed deer in southeastern united states. | the small intestine, large intestine, and cecum of 975 white-tailed deer (odocoileus virginianus) from 83 localities in 13 southeastern states were examined for nematodes. in order of prevalence, the following parasites were found: capillaria bovis, eucyathostomum webbi, monodontus louisianensis, nematodirus odocoilei, oesophagostomum venulosum, trichuris sp, cooperia punctata, trichostrongylus longispicularis, strongyloides sp, cooperia oncophora, cooperia spatulata, cooperia sp, and trichostro ... | 1976 | 977456 |
| efficacy of cydectin moxidectin 1% injectable against experimental infections of dictyocaulus viviparus and bunostomum phlebotomum superimposed on natural gastrointestinal infections in calves. | twenty male holstein calves averaging 105 kg in weight and naturally infected with gastrointestinal nematodes and small numbers of lungworm and hookworm, were given experimental infections with the two latter species to provide adult and larval stages for anthelmintic evaluation. following random allotment, one group of 10 calves was injected subcutaneously with moxidectin at a dosage of 0.2 mg kg-1 of body weight. a second group of 10 was injected subcutaneously with unmedicated blank vehicle a ... | 1992 | 1413460 |
| activity of doramectin against nematode endoparasites of cattle. | a series of 28 controlled anthelmintic studies, involving 634 cattle, was conducted throughout north america and europe to evaluate the efficacy of doramectin against a broad range of gastrointestinal parasitic nematode species and lungworms in naturally and experimentally infected animals. within each study, one or two groups were treated with doramectin at 200 micrograms kg-1 and another group received no drug treatment. worm burdens were estimated by standardised techniques, and efficacy asse ... | 1993 | 8236735 |
| efficacy of doramectin against field nematode infections of cattle in latin america. | two studies were conducted, one in argentina and one in brazil, to evaluate the therapeutic efficacy of doramectin administered subcutaneously at a dose rate of 200 micrograms kg-1 (1 ml per 50 kg) to cattle harboring mixed field infections of gastrointestinal nematodes. in each trial, 20 heifers were randomly allocated to a control or treated group of ten animals each, on the basis of fecal egg counts. animals in the treated and control groups received an injection of doramectin or saline in th ... | 1993 | 8236736 |
| endectocide activity of a new long-action formulation containing 2.25% ivermectin+1.25% abamectin in cattle. | the present work aimed to evaluate the endectocide activity of a new injectable long-action formulation, containing ivermectin (ivm) and abamectin (aba). in each one of the four experiments performed, the following groups were formed: group i: 2.25% ivm (450 microg/kg)+1.25% aba (250 microg/kg), group ii: 3.15% ivm (630 microg/kg) and group iii: control. eighteen bovine naturally infected by gastrointestinal nematoda were selected for anthelmintic evaluation and necropsied on posttreatment day ( ... | 2008 | 18562119 |
| anthelmintic efficacy of oral trichlorfon solution against ivermectin resistant nematode strains in cattle. | infected calves from two different rural estates in brazil were studied to assess the anthelmintic efficacy of oral trichlorfon against naturally occurring ivermectin resistant parasitic nematode strains. in experiment i, infected animals were from a region where ivermectin resistant populations of haemoncus placei, cooperia punctata, cooperia spatulata and trichuris discolor have recently been identified. six calves with natural gastrointestinal nematode infections were treated with 48.5mg/kg a ... | 2009 | 19709817 |
| evaluation of clinical safety and anthelmintic efficacy of aurixazole administed orally at 24 mg/kg in cattle. | the current study evaluated, in vivo, the clinical safety and the anthelmintic efficacy of 24% aurixazole (24 mg/kg), administered orally, in bovines. two experiments were conducted: the first one evaluating the clinical safety of 24% aurixazole (24 mg/kg) in cattle, and a second one evaluating the anthelmintic efficacy of aurixazole (24 mg/kg) against gastrointestinal nematodes on naturally infected cattle. based on the results of clinical safety, no alterations on clinical and haematological s ... | 2014 | 24656344 |
