Prevalencija invazije vrstama roda Cryptosporidium u goveda na području Jugozapadne Nigerije

Abstract

This study investigates the prevalence of Cryptosporidium sp. infection in Oyo state, south western Nigeria. Fecal specimens from 406 cattle were randomly collected and examined for the presence of Cryptosporidium sp. oocysts using the formol ethyl ether concentration and the modified Kinyoun acid-fast staining method. The results showed that the overall prevalence of infection was 23.4% (95/406), with an infection rate of 27.4%, 28.1% and 19.9% in cattle less than 6 months, 7-12 months and over 12 months respectively. Although no significant difference (P>0.05) exists between the age groups, calves less than 6 months of age are more likely to be infected than adults (OR: 1.512; 95%CI: 0.849-2.709). A significant difference (P0,05) među skupinama različite dobi, smatra se da je telad mlađa od šest mjeseci primljivija na invaziju od odraslih. Značajna je razlika (P<0,0001) dokazana između prevalencije u goveda različitoga spola. U krava je dokazana dvostruko veća mogućnost invazije. Stopa invadiranosti iznosila je 84,2% (80/95) u goveda bez proljeva, a 15,8% (15/95) u goveda s proljevom. Nije ustanovljena povezanost između pojave proljeva i prisutnosti oocista kriptosporidija (P = 0,9468; OR: 0,979; 95%CI: 0,522-1,636). Rezultati pokazuju da je invazija protozoima Cryptosporidium sp. česta u Nigeriji, osobito u goveda koja ne pokazuju kliničke znakove bolesti, a mogu biti znatan izvor invazije za ljude
