Campylobacter jejuni, a motile, curved or spiral-shaped, microaerophilic Gram-negative rod, is a common cause of human gastrointestinal infection (Garvis et al., 1996). Drinking water may be the common reservoir causing Campylobacter infection in humans and animals, including wild birds and poultry (Kapperud et al., 2003). Undercooked chicken appears to be linked to a large percentage of campylobacteriosis (Phillips et al., 1997). Poor hygienic conditions and the presence of animals in the home are also responsible for Campylobacter infection (Rao et al., 2001). The presence of waste in cooking areas and the lack of knowledge on the correct sanitary disposal of feces are the main risk factors for contracting this infection (Ghosh et al., 2013). Among other risk factors, red meat, unpasteurized milk, unwashed fruit and vegetables, wild bird feces, compost and sewage are also important (Whiley et al., 2013). Diarrhea is responsible for the death of one in nine children worldwide, making it the second leading cause of death in children under the age of five. The annual mortality rate due to diarrhea in children under five years of age is 10% worldwide (Liu et al., 2012). Among 139 low- and middle-income countries, including Pakistan, there were 1.9 billion cases of childhood diarrhea in 1990 and approximately 1.7 billion events in 2010 (Walker et al., 2012). The European Food Safety Authority and the European Center for Disease Prevention and Control examined the data provided by 27 Member States of the European Union on the occurrence of zoonoses and food-borne epidemics in 2011. According to which campylobact ...... halfway through the article ......) 8.3% incidence of campylobacter infection was detected in 442 children with diarrhea aged 0 to 72 months. Weinberger et al. (2013) studied the prevalence of Campylobacter spp. infection in Israeli children 1999-2010. The incidence of infection in children under two years of age was 356.12 cases/100,000 inhabitants. Mukherjee et al. (2013) studied the prevalence of campylobacter infection in children with diarrhea admitted to the Infectious Disease Hospital in Calcutta, India. From January 2008 to December 2010, 3,186 stool samples were examined. The isolation rate of C.jejuni in children younger than 5 years was significantly high, up to 10.0%. Lengerh et al. (2013) conducted a study in which 285 children with diarrhea under the age of 5 were included. Among 285 cultured stool samples, 44 (15.4%) of them tested positive for Campylobacter jejuni.
