Isolation and antibiogram of pneumonic pasteurellosis causing microbes from nasopharynx of transport stressed Nigerian goats

This investigation reports the isolation and antibiogram of pneumonic pasteurellosis causing microbes, Mannheimia haemolytica (MH) and Pasturella multocida (PM) from the nasopharynx of transport stressed Nigerian goats. Nasal swabs were taken from 63 that were transport stressed (group A), 21 goats that were transport stressed followed by rest for two weeks (group B) and 21 resident goats which were not transported (group C). The characterisation, identification of the isolates was carried out using standard methods while the antibiotics sensitivity test was by disc diffusion technique. The rate of isolation and load of MH and PM from the nasal cavity was significantly higher in transport-stressed goats while there was no significance difference between groups B and C. The duration of journey did not significantly affect the isolation rate of the two organisms except the bacterial load of MH. Most isolates were susceptible to the quinolones (cefuroxime, ciprofloxacin and ofloxacin) and resistant to gentamycin, augmentin, nitrofurantoin, ceflazidime and ampicillin. Efforts should be geared towards improving state of Nigerian roads, animal transportation and the treatment plan that is commonly used for stabilising transport-stressed animals especially with the use of rest and appropriate antibiotics prophylaxis.
