In 1986, 5 commercial bean sites near Holyoke (Colorado, USA) were treated with 4 sprays of cupric hydroxide every 7 to 10 days beginning at least 2 wk. before flowering to (1) sample for the presence of Cu resistance in naturally-occurring epiphytic populations of Pseudomonas syringae pv. syring...

The use of medicinal plants for the prevention and treatment of gastro-intestinal parasitism has its origin in ethnoveterinary medicine. Although until recently the majority of the evidence on the antiparasitic activity of medicinal plants was anecdotal and lacked scientific validity, there is cu...

Rab genes encode a subgroup of small GTP-binding proteins within the ras super-family that regulate targeting and fusion of transport vesicles within the secretory and endocytic pathways. These genes are of particular interest in the protozoan phylum Apicomplexa, since a family of Rab GTPases has...

Five chicken lines were experimentally infected with a HPAI H7N1 virus, to examine the variation in susceptibility to infection. Three lines showed high susceptibility to the virus, while two showed some resistance, with 7 out of 20, and 11 out of 15 birds, respectively, remaining healthy and sur...

Currently, several PCR based diagnostic assays have been developed to improve the detection of pathogenic trypanosomes. These tests include use of species specific primers, single and nested PCRs' based on primers amplifying the Internal Transcribed Spacer (ITS) regions of ribosomal DNA. This stu...

Natural resistance to African trypanosomiasis in certain Bos taurus cattle in West Africa, called trypanotolerance, may hold solutions for control of this economically crippling disease. Comparison of immune responses between trypanotolerant and trypanosusceptible cattle have shown some differenc...

Investigations during 1984 and 1985 demonstrated that Pseudomonas syringae pv. phaseolicola (Psp) and Pseudomonas syringae pv. syringae (Pss) occur as epiphytes on dry beans in Colorado. Populations of syringae-type pseudomonads (STPs) were detected on volunteer bean plants throughout northeaster...

Tumor necrosis factor alpha (Tnf) plays a pleiotropic role in murine malaria. Some investigations have correlated Tnf with hypothermia, hyperlactatemia, hypoglycemia, and a suppression of the erythropoietic response, although others have not. In this study, we have evaluated parasitemia, survival...
The In vitro efficacy of the extracts of Peltophorum africanum Sond. (Fabaceae), was determined against Haemonchus contortus. Acetone extracts of the leaf, bark and root, at concentrations of 0.008 to 25 mg mL 1 were incubated at 23oC with the eggs and larval stage (L1) of the parasite for two an...
