  A cross-sectional study was conducted on the presence of Cryptosporidium oocysts and Balantidium coli cysts in fecal samples from semi-intensively managed pigs in Zuru Local Government Area of Kebbi State, Nigeria between November 2005 and July, 2006. A total of 632 households with human population of 5905 were identified in seven pig- rearing locations in the study area while 105(16.6%) of these households with human population of 1105(18.7%) reared a total number of 3895 pigs. Physical randomization was used to select 50% representative samples of pig-rearing households and pigs for this study. Out of the 402 pigs from 55 households, 207(51.5%) pigs were positive for Balantidium coli cysts, 56(13.9%) for Cryptosporidium oocysts while mixed infection was observed in 29(7.2%). There is significance difference in the distribution of the two parasites in the pigs surveyed (p< 0.05). Young pigs were most affected with infection rates of 33(58.9%) Cryptosporidium oocysts, 113(54.6%) Balantidium coli cysts and 17(58.6%) mix infection. Human fecal samples collected from 53 individuals revealed 3(5.7%) positive cases of Cryptosporidium oocysts all in young ones while a positive case of Balantidium coli cyst infection was found in an adult female. Water and soil samples from two areas were also found to contain both organisms. The semi-intensive system of pig rearing which allowed pigs to scavenge and defecate about, defective personal and environmental hygiene couple with the usage of untreated pig feaces as manure on vegetable farms in the study area can enhance the spread of these zoonotic diseases in human population.

  The present study was conducted to investigate the point prevalence of Cryptosporidium oocysts infection in calves grazing along the bank of Rima River Sokoto in October 2011. The river bank is a converging zone for domestic animals reared in different quarters of the town and the surrounding settlements. A total number of 2,959 cattle were enumerated out of which 147 (4.97%) were calves. Faecal samples were collected from 100 (68.02%) calves by convenient sampling technique. Formol-Ether sedimentation and modified Ziehl-Neelsen staining techniques were used to identify the Cryptosporidium oocysts in the faecal samples. Faecal consistency was also used to identify diarrhoeic and non-diarrhoeic calves. Cryptosporidium oocysts were identified in 33(33.0%) of the calves examined. The detection rate was higher among the male calves (38.46%) than females while the Rahaji breed had the highest prevalence of 62.5%. A total of 6 (18.18%) among the positive cases were diarrhoeic. The differences in prevalence based on sex, breeds and presence of diarrhoea were not statistically significant. Calves may become sources of Cryptosporidia infection to man and other animals in the study area through unrestricted movements and interactions with the environment.

  A survey for the prevalence of trypanosomes species and the anemic status of trade cattle presented for slaughtering at Sokoto main abattoir, Northwest Nigeria was conducted between January and June, 2008. Blood samples were collected at ante-mortem via jugular vein and examined by Standard Trypanosome Detection Methods (STDM). Anaemic status was determined by Packed Cell Volume (PCV) and FAMACHA® Anaemic Guide technique while Polymerase Chain Reaction (PCR) technique was used to detect the presence of Trypanosoma brucei group. Out of 500 samples analyzed by STDM, 9 (1.8%) were positive out of which 6 (66.7%) had Trypanosoma vivax. The PCR technique detected 22 (4.4%) positive cases of Trypanosoma brucei group while 45 (9.0%) cattle were anaemic using the PCV and FAMACHA® techniques, respectively and White Fulani breed had the highest infection rate with 5 (55.6%) cases. These findings are significant as the study area has earlier been declared as tsetse free zone, transhumant activities as practice largely by the cattle herders may be responsible for these detections. Presence of other mechanical vectors may lead to rapid spread of the infection which may have adverse effects on productivity of the animals with resultant economic losses. The detection of the T. brucei group in the examined trade cattle may also portend danger to public health as some ruminants and pigs have been incriminated as reservoir hosts of the Human African Trypanosomosis (HAT) agents in some parts of Africa. Statewide surveillance is therefore, needed to establish the true prevalence of the infection in all domesticated animals in the study area.
