    Investigation of waterborne parasites in drinking water sources of Ankara, Turkey
    (Microbiological Society Korea, 2003) Bakir, B; Tanyuksel, M; Saylam, F; Tanriverdi, S; Araz, RE; Hacim, AK; Hasde, M
    Waterborne parasite infections are considered a re-emerging threat. Most studies on the epidemiology of human cryptosporidiosis, giardiasis, and amebiasis have been carried out in developed countries, and there is little data on the occurrence of these infections in other areas. The objective of this study was to investigate the presence of waterborne parasites such as Cryptosporidium parvum, Giardia lamblia, and Entamoeba histolytica in various water samples in Ankara, Turkey. A total of 85 samples were examined, 43 from the municipal water supply, 34 from wells, 6 from the Ankara River, and 2 from two untreated dams; by conventional microscopy, immunologically and by polymerase chain reaction (PCR). Oocysts of C parvum and cysts of G. lamblia were detected by using an indirect fluorescence (antigen) assay, whereas an enzyme linked immunosorbent assay was used to detect the cysts of E. histolytica and E. dispar. In addition, PCR was used for E. histolytica, E. dispar, C. parvum and G. lamblia detection. G. lamblia was found in 2 of the 34 well water samples, and parasites were found in 3 of the 6 Ankara River samples. The 1(st) contained E. histolytica cysts and Strongyloides stercoralis larvae, the 2(nd) E. histolytica cysts, and Trichuris trichiura eggs, and the 3(rd) C. parvum oocysts only. No parasite was observed in the municipal water samples and untreated dam water samples. These results extend our knowledge on waterborne parasites, such occurrence information on waterborne pathogens assists the management and treatment of municipal water.

    Subclinical laminitis in dairy cattle: 205 selected cases
    (Tubitak Scientific & Technological Research Council Turkey, 2005) Belge, A; Bakir, B; Gönenci, R; Ormanci, S
    The economic importance of lameness in dairy cattle has newly been recognized in Turkey. Lameness incidence in Turkey has been reported to be between 13% and 58%, which is similar to that of other countries where 4% and 55% incidence rates have been reported. The objective of this study was to determine the prevalence of sole lesions associated with subclinical laminitis in the hooves of dairy cattle in Van, Turkey. The risk factors for subclinical laminitis are proposed and discussed. The soles 205 selected dairy cattle were examined. The lesions were determined as solar hemorrhage (61.4%), yellow waxy discoloration (58.5%), heel erosion (23.9%) and white line separation (19%). The sole lesions in cattle were widespread both before and after calving; causative factors must always have been operative. In conclusion, it is thought that husbandry and management are more influential than nutrition in the prevalence of subclinical laminitis in Turkey.
