Asemptomatik köpeklerde görülen Giardia spp. enfeksiyonlarının zoonotik önemi

Öz

Giardia intestinalis (G. lamblia, G. duodenalis) tüm dünyada yaygın olarak görülen, insanlarda ve diğer memelilerde ishal, kusma, kilo kaybı, abdominal ağrı ve dehidrasyona neden olan bir protozoondur. Başlıca bulaşma direkt olarak feko-oral yolla veya indirekt olarak kontamine gıda ve su tüketimi ile gerçekleşir. G. duodenalis köpeklerde asemptomatik seyredebilmektedir. Köpekler Giardia’nın zoonotik genotiplerini herhangi bir klinik belirti göstermeksizin taşıyıp çevreye saçabilmektedir. İnsanlarla aynı ortamda yaşayan asemptomatik taşıyıcı köpekler ve bu köpeklerin dışkısıyla kontamine gıda ve su, insanlar için enfeksiyon kaynağı olabilmektedir. Bu derlemenin amacı köpeklerde görülen Giardia enfeksiyonlarının asemptomatik seyrinin vurgulanması ve asemptomatik taşıyıcılığın insan sağlığı ve çevre üzerine etkilerinin değerlendirilmesidir.

Zoonotic importance of Giardia spp. infections in asymptomatic dogs

Öz

Giardia intestinalis (G. lamblia, G. duodenalis) is a common protozoan in human and other mammals worldwide causing diarrhea, vomiting, abdominal pain, weight loss and dehydration. The major infection occurs via directly faecal-oral route or indirectly contaminated food and water consumption. Dogs can carry the zoonotic genotypes of Giardia without any clinical signs and contaminate the environment. Asymptomatic carrier dogs living in the same environment with humans, food and water contaminated with these dogs' faeces can be a source of infection for humans. The aim of this review is to emphasize the asymptomatic course of Giardia spp. infections in dogs and to evaluate the effects of asymptomatic carriage on human health and the environment.
