“…Poultry are, nevertheless, recognized as asymptomatic carriers of several important human pathogens, including salmonella and campylobacter. Thermotolerant campylobacter bacteria (Campylobacterjejuni and Campylobacter coli) are among the most common causes of diarrhoeal illness in humans in the industrialized world [1,2]. The bacteria are isolated frequently from poultry as well as from poultry products [3,4], and epidemiological studies have incriminated consumption or handling of poultry products as major risk factors for campylobacter infection [5][6][7][8][9].…”

SUMMARYAn epidemiological investigation was conducted to identify risk factors related to hygiene and husbandry practices which determine the introduction of Campylobacter spp. into broiler chicken flocks. All 176 broiler farms in an area in southeastern Norway participated in the study. Each farm was represented by one flock selected at random during a one-year period. The flocks were examined for campylobacter colonization at slaughter, and the flock managers were subsequently interviewed about hygiene and husbandry practices. Campylobacter spp. were recovered from 32 (18%) of the flocks. The proportion of colonized flocks varied geographically and seasonally with a peak in the autumn. The following variables were found to be independently associated with an increased risk of campylobacter colonization using logistic regression analysis: (i) feeding the broilers undisinfected water (odds ratio (OR) = 3-42, P = 0045), (ii) tending other poultry prior to entering the broiler house (OR = 6-43, P = 0O007), (iii) tending pigs before entering the house (OR = 4-86, P = 0O037), (iv) geographic region (Hedmark versus 0stfold county) (OR = 2-91, P = 0-023, (v) season (autumn versus other seasons) (OR = 3*43, P = 0008). Presence of rats on the farm was associated with an increased risk, but this factor did not reach statistical significance (OR = 3-96, P = 0O083). Preventive measures should include disinfection of drinking water and strict hygienic routines when the farm workers enter the rearing room. The results indicate that disinfection of drinking water is the preventive measure most likely to have the greatest impact on the prevalence of campylobacter among broiler chicken flocks in the study area (population attributable fraction = 053).

“…During the last decade, campylobacter has been shown to be an important cause of diarrhoea worldwide, affecting persons of all ages, in both industrialized and developing nations [1,2]. For infants and young children of tropical developing countries, campylobacter-associated diarrhoea is a major health problem, contributing substantially to childhood morbidity and mortality.…”

Campylobacter diarrhoea and an association of recent disease with asymptomatic shedding in Egyptian children

et al. 1991

SUMMARYA hospital-based case-control diarrhoea survey was conducted in Cairo, Egypt to determine the age-specific frequency of campylobacter infection among diarrhoeic and non-diarrhoeic children aged new born to 5 years. Campylobacter was the most common bacterial enteropathogen isolated from diarrhoeic stools. The overall prevalence of campylobacter isolations was 25 9 % from stools of 143 diarrhoeic children compared to 152 % of 132 non-diarrhoeic control children (P = 0 028) during the 4-month period of study. Children less than 1 year of age were at greatest risk of campylobacter infection with 32-6 % of diarrhoeic patients culture positive, compared to 14-3 % of controls. Asymptomatic shedding in controls was positively associated with a recent diarrhoeal episode (P = 0 019) and may be an important source of new infections.

“…All of these findings suggest the potential implication of animals as a contaminating source for human infections. Other studies [2,3] have shown animal sources to be a major reservoir for strains infecting humans. So far 30 other phage types were exclusively observed in human infections (Tables 3 and 4), further emphasizing the necessity of examining a sufficiently large number of campylobacter strains from non-human sources.…”

SUMMARYThe extended phage-typing scheme described for Campylobacter jejuni and Campylobacter coli has established 46 different phage types using 19 typing phages. Altogether 754 campylobacter isolates, 672 C. jejuni and 82 C. coli, isolated from human and non-human sources received from 17 different countries were phagetyped. Overall, 80 6 % of the total isolates were typable. Among typable strains, 9 phage types (3, 5, 10, 11, 18, 19, 23, 26 and 44) represented 57-0 % of the strains, 21P3 % of the strains belonged to another 37 phage types and the remaining 2f3 % of isolates were designated atypical. The most common phage type 11 (140/754) was frequently observed among C. jejuni isolates from human (113/561) and nonhuman sources (18/ 111), whereas type 44 was frequent among C. coli isolates from human (22/59) and from non-human sources (8/23). A study of the animal hostassociations of common phage types showed that contaminated cattle and poultry appear to be the most common sources of human infection. The greatest variety of phage types was observed in Canada (24 phage types), followed by Portugal (17 types) and the UK (14 types), reflecting the larger sample sizes from these countries. Phage type 11 was encountered in 12 different countries and prevalence of other phage types varied from one country to another. The number of isolates typable with the scheme varied from 93-2 % (261/280) in Canada to 61 % (47/77) in Thailand. However, the number and diversity of phage types makes phage typing the method of ehoice in epidemiological studies of campylobacter infections.
