Bovine hypodermosis in North-Central Algeria: Prevalence, intensity of infection and risk factors

Büvelek sineği enfestasyonu (WFI) üzerine bir epidemiyolojik araştırma gerçekleştirmek üzere Ocak-Haziran 2009 döneminde Bejaia Bölgesinin (Kuzey-Orta Cezayir) en büyük hayvan pazarı ve beş sığır çiftliği ziyaret edildi. Pazar ve marketlerde sırası ile toplam 3.442 ve 226 sığır klinik olarak muayene edildi. Prevalansın çiftliklerde (%18.1) hayvan pazarına gore (%3.7) daha yüksek olduğu belirlendi. Fakat, enfeksiyonun şiddetinin pazarda (12.61±7.78 vs 7.5±4.15) en yüksek olarak gözlemlendi. Ekstansif yetiştiricilikte en yüksek yaygınlıklta olan WFI prevalansı üzerine yetiştirme sistemi önemli bir etki göstermektedir. Ancak, sığır yaş, cinsiyet ve ırk özelliklerinin WFI yaygınlığı üzerinde önemli bir etki göstermediği belirlendi. Enfeksiyon yoğunluğunu etkileyen tek faktor olarak ırk özelliği bulundu; melez ve yerli ırk ile karşılaştırıldığında Montbeliarde ırkının en ağır enfestasyona maruz kaldığı gözlemlendi.

Kuzey-Orta Cezayirde sığır hypodermosis: Yaygınlık, enfeksiyon yoğunluğu ve risk faktörleri

From January to June 2009 the biggest livestock market and five bovine farms of Bejaia department (Northcentral Algeria) were visited in order to undertake an epidemiological survey on warble fy infestation (WFI). A total of 3.442 and 226 bovines were clinically examined in both market and farms, respectively. The prevalence was higher in farms (18.1%) than in the animal market (3.7%). On the contrary, the intensity of infection was highest in the market (12.61±7.78 vs 7.5±4.15). The husbandry system exerts a significant efect on the prevalence of WFI, being the prevalence highest under extensive management. However, cattle age, sex and breed did not exert a significant efect on WFI prevalence. Breed was the only factor infuencing the intensity of infection; the Montbeliarde breed was the most heavily infested as compared to the crossbreed and the local breed.
