| sero-prevalence of agglutinins to listeria monocytogenes in nigerian domestic animals. | a survey using tube agglutination test was conducted to determine the antibody prevalence to listeria monocytogenes serotypes 1/2a, 1/2b, 1/2c, 3a and 4b in 1,190 serum samples of 8 animals species from various sources in kano and kaduna states of nigeria. following absorption with staphylococcus aureus antigen to remove cross-reacting agglutinins, 52 (68.4 p. 100) of the horse samples were positive. twenty-six (36.1 p. 100) pig, 52 (20.8 p. 100) cattle, 50 (20.0 p. 100) goat, 20 (20.0 p. 100) d ... | 1989 | 2518470 |
| toxin-types of clostridium perfringens strains isolated from sheep, cattle and paddock soils in nigeria. | two-hundred and forty-five strains of clostridium perfringens isolated from the faeces of apparently healthy sheep and cattle and from their environments (paddock soils) in kano and kaduna states of nigeria were studied. the isolates were examined by the toxin-antitoxin neutralisation tests performed intradermally in depilated albino guinea-pigs. one-hundred and twenty-seven (53.1%) of the isolates were type a, 17 (7.1%) were type b, 14 (4.9%) were type c, 44 (18.4%) were type d and 19 (7.9%) we ... | 1986 | 2873674 |
