An outbreak of swine pox on a pig farm in Ibadan, Nigeria is reported. Diagnosis was based on clinical and pathological signs and the observation of poxvirus particles in a serum sample. Neonatal deaths were common in the outbreak. Indigenous pigs did not show any sign of the disease even though mixed breeds were kept in the same pens. It is suggested that indigenous pigs were probably carriers of the swine pox virus.

Summary An investigation was carried out to study the haematology of steroid immunosuppressed horses experimentally infected with Babesia equi and Ehrlichia equi, separately or simultaneously. Horses infected with both pathogens showed less marked changes in their haematology than those inoculated with either pathogen separately. This appeared to result from early elimination of the more pathogenic Babesia as Ehrlichia spread through the granulocytes. The apparent suppression of Babesia by Ehrlichia is of field clinical importance and merits further investigation for its apparent useful potentials in the control of babesiosis in endemic areas.

SummaryA survey of gastro‐intestinal helminth parasites of grey‐breasted helmet guinea fowl (Numida meleagridis galeata Pallas) was carried out between April and September 1979. Faecal samples were collected and examined for helminth eggs and/or oocysts. Heterakis sp., Capillaria sp., Dispharynx (Acuria) sp., Prosto‐gonimus sp., Hymenolepsis sp. and oocysts of Eimeria sp. were identified from guinea fowl. Heterakis sp. were the most prevalent. Mixed infections occurred in 73.8% of the infected birds. A point prevalence rate of 67.4% was recorded with varying degrees of clinical infection. The potentials of the grey‐breasted helmet guinea fowl acting as a disseminator of these parasites to chickens or vice‐versa is highlighted and the need for pre‐market treatment as a means of improving the survival rate and market value of this game bird is recommended.RÉSUMEÉOn a entrepris entre avril et Septembre 1979 un contrǒle des helminthes gastrointestinaux parasites de la pintade commune (Numida meleagridis galeata, Pallas). Des échantillons de déjections furent collectés et examinés pour trouver des oeufs et/ou des oocystes. On a identifié chez la pintade: Heterakis sp., Capillaria sp., Dispharynx sp., Prostogonimus sp., Hymenolepsis sp., et des oocystes de Eimeria sp. I1 y a une nette prévalence de Heterakis sp. On a trouvé des infections mixtes chez 73.8% des oiseaux parasités. On a relevé un taux de prévalence de 67.4% associéà divers degrés d'infection clinique. Le rǒ1e potentiel de cette pintade comme vecteur de parasites vers les poussins et vice‐versa est mis en évidence; la nécessité d'un traitement des animaux avant de les mettre sur le marché est recommendé comme moyen d'améliorer leur survie et leur valeur marchande.
