Distribution of liver and lung helminthic infections among slaughtered animals in Kirkuk abattoir

Abstract

The aim of this study was to determined the distribution rate of some parasitic helminthes in liver and
lung among slaughtered ruminants and demonstrated seasonal factor effect on helminthic infections.
Across section study was conducted in domestic ruminant to determine the prevalence and risk factor of
helminthiasis, a total of 199738 domestic ruminants slaughtered in Kirkuk abattoirs during 2009-2011.
The study revealed that the overall prevalence of helminthiasis in domestic ruminant was 5048(2.5%), the
species level prevalence of helminthiasis was1379 (10.2%) and 25(6.3%) in cattle and buffaloes, in sheep
and goat 3138(2.3%) and306 (1.6%) respectively and lower rate of the infection in calve was 200(0.5%).
Hydatid cyst were the most prevalent parasite 3325(1.6%) followed by liver flukes 1242(0.6%) then lung
worms 481(0.2%). The highest rate of infection with hydatid cyst was in cattle and buffalo 744(5.5%),
9(2.2%) respectively followed in sheep and goat were 2174(1.6%) and 219(1.1%). liver flukes investigation
were higher in cattle and buffalo 436 (3.2%), 9(2.2%) respectively then in sheep, goat 718(0.5%) and
64(0.3%), while lung worms were higher infection in buffalo and cattle 7(1.7%) and199 (1.4%) followed by
sheep and goat 246(0.1%) and 23(0.1%) respectively. According to seasonal variation the inflectional rate
of helminthiasis in summer was indicated higher percentage of helminthes 1468(29%) and in autumn
1385(27.4%) followed by in winter 1254(24.8%) then in spring 943 (18.6%). Hydatid cyst showed highly
percentage in summer 1025(30.8%) and autumn889 (26.7%) then in winter 818(24.6%) and spring
was593 (17.8%). While infection rate of liver flukes were higher in autumn and summer 366(29.4%),
359(28.9%) respectively then in winter 289(23.2%) in spring 228(18.3%), another parasitic type lung
worms were higher in winter146 (30.3%) followed by infection in autumn 130(27%) and spring
122(25.3%) then in summer 84(17.4%).
