The prevalence of Giardiasis in cattle slaughtered in the Sokoto metropolitan abattoir was investigated. Faeces and bile samples were collected and processed using formal-ether concentration technique. The essence of this study was to establish the prevalence of Giardiasis in Sokoto metropolitan abattoir. Gross lesions from 224 out of 1, 313 slaughtered cattle were randomly selected and examined. Out of the 224 cattle examined, 56 (25.00%) were infected. Out of the 95 male cattle examined, 20 (21.05%) were infected, out of 129 female cattle examined, 36 (27.91%) were infected. The infection withGiardia sppin the examined breed was also found to be 56 (25.00%) in relation to breed out of 100 Sokoto Gudali breed examined, 20 (20.00%) were infected, and out of 123 Red Bororo breed examined, 36 (29.27%) were infected. While 1 white Fulani breed was examined, and 0 (0.00%) was infected. The overall prevalence of infection with Giardia was 27.68% and there was a significant difference (p > 0.05) between the rate of infection in males and females and between breeds. Regular treatment of all animals and humans with an effective antiprotozoal drugs such as Metronidazole (Flagyl®), Tindamax®(Tinidazole), proper abattoir inspection, adequate and clean water supply to animals; payment of compensation by government, and public enlightenment about the disease by government non- governmental organizations (NGO's) on health implication inherent in unsafe disposal of human and animal faeces were suggested.This strategy will help to protect animals and the general public from Giardiasis in our country.

A survey of zoonotic gastrointestinal parasites in dogs (Canis familiaris) slaughtered at Zuru and Bedi dog markets in Zuru Local Government Area of Kebbi state was conducted between the May, 2007 to July, 2007. A total of 52 faecal samples (33 males and 19 females) were collected after the evisceration of the intestinal contents. The faecal samples were collected from the intestines immediately after evisceration. The faecal samples were analyzed using Zinc sulfate floatation technique. The study showed an overall prevalence of gastrointestinal parasites to be 41(78.85%), with all the parasites found to have zoonotic potential. The prevalence for the various helminth eggs observed were:Uncinaria stenocephala21(32.31%),Ancylostoma spp.10(15.38%),Toxocara canis7(10.77%),Isospora spp. 6(9.23%),Dipylidium caninum5(7.69%),Taenia spp. 5(7.69%),Strongyloides stercoralis5(7.69%),Alaria spp. 4(6.15%) andToxocara leonina2(3.07%). Parasites of zoonotic importance are highly prevalent in Nigerian dogs, as such public health enlightenment should target dog consumers, butchers, owners; and the prohibition of stray dogs through policy legislation and enforcement as possible control measures.

The study was carriedout to establish the prevalence of Yersinia enterocolitica and Yersiniapseudotuberculosis in pigs in Zuru Local Government of Kebbi State. Feacalsamples were collected from the randomly selected pigs and analysed usingstandard bacteriologic method of Yersinia isolation and identification. A totalof 377 samples were collected, out of which 76(20.2%) samples were positive forYersinia species. Yersinia enterocolitica was found in all the positive sampleswhile only 7(9.2%) were positive for Yersinia pseudotuberculosis. Thedistribution of isolates among various age groups shows higher percentage ofoccurrence of 59.2% in pigs above 24 months of age, while the low incidencerate (9.2%) was recorded in pigs of 1 to 12 months of age. There wasstatistical association between the rate of isolation and the age, as p valuesare less than 5%(p<0.05). This investigation has revealed the presence ofYersinia enterocolitica and Yersinia pseudotuberculosis among pigs in the studyarea. Therefore, there is need to educate the pig rearing communities andpublic on the need for hygienic practices.
