The prevalence of gastrointestinal helminth infections of dog in Enugu State, South Eastern Nigeria was studied retrospectively and prospectively. In the retrospective study, records of all diagnosed helminth infections of dogs brought to the University of Nigeria Veterinary Teaching Hospital, Nsukka from January, 2006 to September 2013 were collated and analyzed. The prospective study was carried out between October 2013 and July 2014 by examination of 263 faecal samples collected per rectum from dogs presented to a purposively selected Veterinary Clinics in Enugu metropolis and the Veterinary Teaching Hospital of the University of Nigeria, Nsukka. The results of the 8 year retrospective prevalence study gave an overall prevalence of 56.1% and Ancylostoma species as the most prevalent helminth in the study area (33.2%). Mixed infections with more than one helminth parasite species were recorded in 8.6% of the cases. Annual breakdown of the prevalence data showed that the highest prevalence was recorded in 2009. Breed and age of the dogs were found to significantly influence the prevalence. In the prospective study, an overall prevalence of 51.7% was obtained. Ancylostoma spp. was also found most often in the study area, with a prevalence rate of 33.6%. Mixed infections with more than one helminth parasite species were found in 16.3% of the cases. A strong association was obtained between prevalence and breed of the dogs and also between prevalence and season. Due to the zoonotic nature of most of the encountered parasites and the close association between children and dogs, routine deworming, proper management of dogs and adequate personal hygiene is therefore recommended.

The prevalence of gastrointestinal helminths of local chickens in Nsukka region of Southeastern Nigeria was studied using 125 free range local birds purchased from four communities in Nsukka zone namely, Obolloafor, Orba, Nsukka urban and Owerre Eze-orba. The birds were sacrificed humanely and their oesophagus, crop, proventriculus, gizzard, small intestine and caecum examined for the presence of gastrointestinal helminths. Worms when present were isolated and identified using standard parasitological procedures. The study identified four species of cestodes namely Raillietina echinobothridia, R. tetragona, R. cesticillus and Choanotaenia infundibulum and two species of nematodes namely, Ascaridia galli and Heterakis gallinarum. Results obtained showed 96.8 % prevalence of gastrointestinal helminth parasites in the birds with cestodes being the more prevalent class (70.4 %). Raillietina spp was the most prevalent cestode encountered and A. galli the most prevalent nematode. Prevalence rates of infections recorded 14.4 % for nematode species, 26.4 % for cestodes and 56 % for mixed infections of nematodes and cestodes. It was concluded that local chickens are common in the area and could serve as a potential source of helminth infections to intensively managed birds in the study area.

The blood glucose levels of rats were assessed following experimental Trypanosoma brucei infection and diminazene aceturate treatment. Ten adult female albino rats were randomly assigned into two groups of five rats each. Group A were infected with 10 6 trypanosomes while group B served as the uninfected control group. Group A rats were treated with 7 mg/kg Dinazene Ò (diminazene aceturate) at the peak of parasitaemia. Blood glucose level was assayed weekly while parasitaemia level was assessed daily. The blood glucose levels of the infected rats did not vary significantly (P [ 0.05) from that of control group except following relapse when the values became significantly (P \ 0.05) low. The implications of blood glucose reduction following relapse infection in rats is therefore highlighted and discussed.
