    Trichostrongylosis in cattle from south Marmara Region of Turkey: Assessment of various factors related to faecal egg counts
    (Kafkas Univ, Veteriner Fakultesi Dergisi, 2010-01-01) Tınar, Recep; ŞENLİK, BAYRAM; ÇIRAK, VELİ YILGÖR; AKYOL, ÇETİN VOLKAN; Veteriner Fakültesi; Parasitemoloji Ana Bilim Dalı; 0000-0003-2964-2245; 0000-0003-0570-2514
    A cross-sectional study was carried out to determine faecal egg density in trichostrongyle infections in relation to animal age, animal breed, management system and farm type in cattle in South Marmara region of Turkey. Rectal faecal samples were collected from 513 cattle and coprological examination were conducted by a modified McMaster technique to determine faecal egg counts (FEC) per gram of faeces. Overall egg density was 81.4 +/- 6.8 EPG and it remained generally low. The mean faecal egg counts for adults was higher than those for the youngs. However, no statistically significant difference was found between the age groups for faecal egg counts. Although mean FEC were higher in Turkish Grey than in Holstein and Karacabey Bown, no statistically significant difference could be determined among the animal breeds. Management system was the factor that influenced number of trichostrongyle eggs and animals under semi-extensive system had more egg counts than those kept under intensive management system. Animals in the governmental farm have been found less affected with significant difference than their counterparts at small scale private farms.

    Studies on sheep lungworms in Bursa Province of Turkey: Determination of prevalence and relationships between larval output and parasite burden in the lungs
    (Zoological Soc Pakistan, 2008-01-01) Girişgin, Oya; ŞENLİK, BAYRAM; GİRİŞGİN, OYA; GİRİŞGİN, AHMET ONUR; Girisgin, Ahmet Onur; Akyol, Volkan; AKYOL, ÇETİN VOLKAN; Veteriner Fakültesi; Parasitoloji Ana Bilim Dalı; 0000-0003-2964-2245; 0000-0002-0020-2708; B-5286-2017; JRY-1676-2023
    This study was carried out to determine lungworm species and their prevalence, evaluate the effect of host age and breed oil the infections and the correlation between faecal larvae counts and adult lung worms counts in sheep in Bursa Province, Turkey. A total of 104 sheep of different age and breed were examined for the lungworm infection. prevalence of infection was 45.1% and 62.5% by coproscopy and necropsy, respectively. The faecal examination and postmortem showed Dictyocaulus filaria (23%; 31.7%), Cystyocaulus ocreatus (24%; 31.7%) and Protostrongylus rufescens (3.8%; 5.8%). Seven (6.7%) and six (5.7%) sheep had mixed infections with two nematode species in necropsy and faecal examinations, respectively. There was a significant difference (p<0.05) between >4 year old and <4 year old age groups. There was no significant difference in the prevalence of lungworm infections in different sheep breeds. Although there was a positive correlation between larval excretion in faeces and lung nematode counts, reliable regression equations could not be established. Therefore, the number of worms in the lungs Could not be deducted exactly from faecal lungworm larvae counts.
