Acute infectious zoonotic disease known as campylobacteriosis is brought on by thermophilic campylobacters (C. jejum, C. coli, and C. lardis) [2]. It was long thought to be solely a veterinary issue, but within the last 20 years of the 20th century, sufficient evidence has been gathered to show that Campylobacter plays a significant role in the pathogenesis of acute gastrointestinal infections (AII) in people of all ages. The present broad incidence of campylobacteriosis, which is on the rise everywhere, makes research on the illness extremely important [4]. This could be because of the elevated levels of morbidity and significant socioeconomic harm caused by the infection, as well as the intense spread of infections among humans, animals, and the natural world around them. Acute enteritis in people and animals has consistently been primarily caused by campylobacteriosis. Campylobacter is still an underdiagnosed pathogen in canines, sometimes mislabeled or disregarded as an acute antibiotic response. In dogs, Campylobacter infections are either incorrectly identified, left untreated, or treated as a straightforward case of acute enterocolitis that responds to medication. Zoonotic bacteria called Campylobacter spp. are frequently detected in the digestive systems of a variety of animals, including cats, dogs, and avian species [1]. The aforementioned bacteria can be identified by methods involving PCR or straight culture on media designed specifically for Campylobacter [3]. No studies were performed on the prevalence of campylobacteriosis in canines all over Lebanon. Therefore, the aim of this study was to investigate the rate of Campylobacter spp. in dogs all over Lebanon.
