Aim:Coccidiosis is an important enteric parasitic disease of poultry associated with significant economic losses to poultry farmers worldwide. This survey was conducted from June 2014 through July 2015 with the main goal of investigating the prevalence and associated risk factors of coccidiosis among village and exotic breeds of chickens in Maiduguri, Northeastern Nigeria.Materials and Methods:A total of 600 fecal samples from live and slaughtered birds comprising 284 young, 141, growers and 175 adult birds; 379 male and 221 female birds; 450 exotic and 150 local breeds of birds were randomly collected either as bird’s fresh droppings or cutting open an eviscerated intestine of slaughtered birds, while noting their age, sex, and breeds. Samples were analyzed using standard parasitological methods and techniques.Results:An overall prevalence rate of 31.8% (95% confidence interval: 28.07-35.52) was obtained. Higher prevalence rates were recorded in growing birds 58.9% (50.78-67.02), female birds 35.3% (29.00-41.60), exotic birds 42.4% (37.83-46.97), and broiler birds 68.7% (61.28-76.12). Similarly, higher infection rates were also observed among birds sampled from Mairi ward 66.7% (56.03-77.37), intensive management system 46.5% (41.61-51.39), and constructed local cages 54.0% (46.02-61.98). The difference in prevalence of coccidiosis among age groups, breeds, among exotic breeds, sampling sites, husbandry management systems, and litter management systems was statistically significant (<0.0001). However, no significant difference (p>0.05) of infection rates was observed in sex.Conclusion:Coccidiosis is endemic in both commercial and backyard poultry farms in Maiduguri due to poor management practices encouraging Eimeria oocysts build-up. It is therefore, recommended that poultry farmers should practice strict biosecurity measures on their farms, creating awareness on the prevalence of coccidiosis, routine vaccination against coccidiosis and educating poultry farmers on the need for maintaining good hygienic standards and good flock health management.

Aim:To determine the seroepidemiological patterns of bovine brucellosis in three senatorial zones of Bauchi State, Nigeria.Materials and Methods:Blood samples were aseptically collected from the anterior jugular vein of 336 slaughtered cattle, between September 2013 and March 2014 in three senatorial zones of Bauchi State, Nigeria. The sera obtained were screened for brucellosis using rose Bengal plate test (RBPT) and serum agglutination test (SAT) in parallel. The data generated was subjected to Chi-square and Fishers exact test analysis to establish whether there is a relationship between the breeds, sex, and location of the animals sampled.Results:Of the 336 cattle screened, 18 (5.4%) and 13 (3.9%) were positive by RBPT and SAT, respectively. There was no statistically significant association (p>0.05) between the sex, age, and location of cattle with seropositivity of brucellosis in the state. It was concluded that brucellosis is prevalent in Bauchi State. Further study is recommended in other abattoirs and herds of cattle in Bauchi State for confirmation of the status of the disease among cattle slaughtered in the state.Conclusion:A high seroprevalence of brucellosis among the cattle in Bauchi state indicates that the disease is endemic and cattle are one of the animals that perpetuate and sustain the disease.

The present study was carried out between the months of October, 2014 to April, 2015 and aimed at determining the dry season prevalence of avian coccidia infection and their degree of severity among domesticated chickens (Gallus domesticus) in Jere Council, Borno State, Nigeria. A total of 430 fresh faecal and gut samples were collected from chickens of both exotic and local breeds. The samples were examined using floatation and intestinal impulsion smear techniques. The study was conducted among breeds (exotic vs. local), sexes (male vs. female), ages (young vs. adult), management systems (intensive vs. extensive) and housing (cage vs. deep litter). Out of the 430 faecal samples examined, 54 (12.60%) were positive for various Eimeria species. Infection was more in the exotic (7.90%) than the local breed (4.70%). Coccidia infection found in young (10.0%) was higher (P= 0.0001) than in adult chickens (2.60%), while female ones had higher (P= 0.03) number of coccidia than the males. Chickens reared under poor management system showed higher infection (10.20%) compared to the good management one (2.30%). Chickens reared under intensive deep litter housing has higher coccidial load (9.30%) than those reared under extensive system (3.30%). Eimeria necatrix had the highest degree (42.60%) of severity score (+4), followed by Eimeria acervulina (27.80%), Eimeria tenella (24.10%) and E. maxima (5.60%) with degrees of severity scores +3, +4 and (+3) respectively. In conclusion, there was presence of coccidia infection in Jere area of Borno State, Nigeria.
