Prevalencija oocista kriptosporidija u goveda u Južnoj Gani.

The prevalence of Cryptosporidium species oocysts in 241 cattle from two agroecological zones in Southern Ghana was investigated in this study. Cryptosporidium oocysts were demonstrated in fecal samples using sodium chloride centrifugal floatation, followed by the modified Ziehl-Neelsen acid-fast staining technique. Overall, 29.0% of the cattle were positive for Cryptosporidium oocysts. Prevalence was significantly higher (P0.05). Age group prevalence was 25.8%, 33.3% and 27.6% in calves (≤10 months old), young cattle (11 to 24 months old) and adults (>24 months old) respectively (p>0.05). Cryptosporidium oocysts were detected in 23.1% of 39 diarrheic and 30.2% of 202 non-diarrheic stools (P>0.05). The majority of infected cattle were asymptomatic. These findings suggest that cattle may play a role in the zoonotic transmission of Cryptosporidium oocysts to humans and other animals in Ghana.Istraživana je prevalencija oocista vrsta roda Cryptosporidium u 241 govedu na dvama agroekološkim područjima u Južnoj Gani. Oociste kriptosporidija bile su dokazane u uzorcima fecesa metodom flotacije u fiziološkoj otopini te naknadnim bojenjem po preinačenom Ziehl -Neelsenovom postupku acidorezistentnog bojenja. Oko 29,0% goveda bilo je pozitivno na oociste kriptosporidija. Prevalencija je bila značajno veća (P0,05) dokazane u mužjaka (28,4%) i ženki (31,8%). Prevalencija u teladi (u dobi ≤10 mjeseci) iznosila je 25,8%, u junadi (od 11 do 24 mjeseci) bila je 33,3%, a u odraslih (>24 mjeseci) 27,6% (P>0,05). Oociste kriptosporidija bile su dokazane u 23,1% od 39 uzoraka proljeva i 30,2% od 202 uzorka normalno formiranog fecesa (P>0,05). Većina zaraženih goveda nije pokazivala nikakve znakove bolesti. Ovi nalazi upućuju na zaključak da govedo može imati ulogu u zoonotskom prijenosu oocista kriptosporidija na čovjeka i neke vrste životinja u Gani
