Abstract
The prevalence of cryptosporidial infection among captive wild animals and birds in Sanda Kyarimi Park, Maiduguri, north-eastern Nigeria, was evaluated by faecal examination for oocysts using three different staining techniques: the modified Ziehl-Neelsen, Giemsa, and Safranin-methylene blue. A total of 66 captive wild animals and birds were examined based on age and sex differences. Fifteen (22.7%) of the animals examined were young and 51 (77.3%) were adults; 36 (54.5%) were males and 30 (45.5%) were females. Age and sex were found to have no significant effect on the prevalence of infection among the different age and sex groups. A total of 15 (22.7%) positive samples were recorded using the modified Ziehl-Neelsen stain, while Giemsa and Safranin-methylene blue stains recorded 12 (18.2%) and 8 (12.1%) positive cases, respectively. Captive wild animals and birds could play an important role in the epidemiology of cryptosporidiosis as a zoonotic infection.Kriptosporidioza u divljih sisavaca i ptica držanih u zatočeništvu u sušnom području u parku Sanda Kyarimi u Maiduguriju u sjeveroistočnoj Nigeriji određena je koprološkom pretragom dokazivanjem oocista različitim metodama bojenja. Rabljeno je preinačeno bojenje po Ziehl-Neelsenu, po Giemsi te bojenje safraninmetilenskim plavilom. Ukupno je pretraženo 66 divljih sisavaca i ptica. Za sve su životinje zabilježeni podatci o spolu i dobi. Pretraženo je 22,7% mladih te 77,3% starih životinja te 54,5% mužjaka i 45,5% ženki. Nije dokazano da dob i spol utječu na učestalost kriptosporidioze u pretraženih životinja. Preinačenim postupkom po Ziehl-Neelsenu dokazano je ukupno 15 (22,7%), bojenjem po Giemsi 12 (18,2%) te bojenjem safranin-plavilom 8 (12,1%) pozitivnih uzoraka. Istraživanje je pokazalo da različite divlje životinje i ptice mogu imati značajnu ulogu u epidemiologiji kriptosporidioze
