“…The serogroups found in sheep in this study were similar to those reported in domestic animals previously in Nigeria (Adegbola et al, 1990(Adegbola et al, , 1991 and in humans (Alabi et al, 1986;Coker and Adefoso, 1994).…”

“…Several epidemiological studies in developed countries have identi®ed sources of Campylobacter enteritis in man to include animals, food, water, and milk products (Khan, 1982;Skirrow, 1982). Although there are sporadic reports of Campylobacter enteritis in developing countries particularly Nigeria (Olusanyo et al, 1983;Alabi et al, 1986;Ani et al, 1988), very little is known concerning its mode of spread.…”

“…A proper understanding of the epidemiology of Campylobacter infections is necessary for the planning of effective prevention and control measures (Adegbola et al, 1990;Raji et al, 1997). Moreover, previous observations of the prevalent biotypes and serogroups of Campylobacter isolates from humans (Alabi et al, 1986), and animal sources, especially poultry and pigs (Olubunmi and Adeniran, 1986;Adegbola et al, 1990), have encouraged us to examine the role of sheep in human Campylobacter enteritis in Nigeria. This paper, therefore, document the isolation, biotyping and serotyping of Campylobacter species isolated from sheep in Nigeria.…”

Sheep Campylobacter isolates from Kaduna State were characterized into their species and bioserogrouped. A total of 1100 samples were collected from Kaduna abattoir and National Animal Production Research Institute (NAPRI), Shika. The samples were from 250 gallbladder, 250 intestinal contents, 100 fetal stomach contents all from Kaduna abattoir while 250 rectal swabs and 250 vaginal swabs were from the NAPRI Small Ruminant Programme. Of a total of 1100 samples, 39 (3.54%) yielded Campylobacter organisms. The highest isolation rate (6.8%) was from samples of intestinal contents followed by those from gall bladders (4.0%). Samples from the vaginal and fetuses had the lowest isolation rates (2.80%) and (0%), respectively. Of the 39 Campylobacter isolates from all the sources, (79%) were characterized as C. fetus subsp jejuni, C. coli (13%) and C. laridis (8.0%). while C. coli and C. laridis were isolated from gall bladder and intestinal contents only. Campylobacter fetus subsp jejuni biotype 1 accounted for 40.3% of the total isolates. C. laridis biotypes I and II were also isolated and accounted for 5% and 3% of the isolates, respectively. 5% of the isolates were not typeable. The serogroups 4 (13%), 36 (10%), 9 (10%), 84 (8%), 29 (5%) and 20 (8%) were the commonest serogroups identified in sheep at two locations surveyed. The isolation of Campylobacter organisms from rectum, vagina, gallbladder, and intestinal contents is a clear indication that sheep serves as a reservoir of this organisms in Nigeria. Similarities between documented human Campylobacter isolates in Nigeria and those in the present study raised the possibility of cross-transmission between sheep and man. It is concluded that biotyping and serotyping can be used for epidemiological study of campylobacteriosis due to Campylobacter jejuni in sheep in Kaduna State of Nigeria.

“…C'ampylobacter jejuni is an important case of acute diarrhoeal disease occurring in both sporadic and epidemic form (Blaser et al 1983;Svedhem & Kaijser, 1980;Skirrow, 1987;. Repeated enteric infection with this organism is particularly prevalent in children in developing countries where most of the cases occurring in children over 2 years old are asymptomatic (Glass et al 1983;Calva et al 1988;Mathan et al 1984; Georges-Courbot et Alabi et al 1986). It has been claimed that different strains appear in the repeated infections, but that a limited number of serotypes dominate (Blaser et al 1986;Karmali et al 1983).…”

The presence of different Campylobacter jejuni serotypes in Swedish patients with diarrhoea and in Mexican patients with or without diarrhoea was investigated with special reference to repeated isolations during the course of infection and to symptomatic and asymptomatic episodes. The study included 136 C. jejuni isolates from 62 Mexican children and 173 isolates from 68 Swedish patients. The bacteria were serotyped for heat-stable (HS) and heat-labile (HL) antigen. Swedish patients, all with symptoms, were in general only infected with one serotype and were rarely reinfected. Mexican patients on the other hand were in general infected with mixed serotypes and frequently reinfected without symptoms with new, different serotypes, a finding which is in concordance with a theory of an induced immunity to surface antigens.

“…In Canada, also, three of our leading serovars from patients were found among the top five (7, 4, 1, 36, 2) (Lior 1984a). Serovars 36 and 4 were by far the most predominant types found in cases of enteritis in hospitalized children in Nigeria (Alabi et al 1986), and serogroups 4 and 9 have been reported as the aetiological agents of an outbreak in the USA (Blaser & Patton 1985).…”

A total of 318 Campytobacter strains from sporadic cases of human enteritis (109 strains) and healthy slaughterhouse animals in northern Germany (209 strains) were bio-and serotyped according to the Lior typing schemes. Three hundred strains were typable (94.3%) and 38 serovars were identified. Among human strains 28 serovars were identified with 30% of them belonging to serovar 4. Strains from pigs were associated with 25 serovars, the most frequent being serovar 20 (21.2%). Fourteen serovars were identified in the ovine strains of which 31.1% were of serovar 49, and 22.2% of serovar 4. All of the strains from one chicken farm were of serovar 11, whereas in those from another serovar 1 was predominant (85.4%). Twenty-five of the 38 serovars identified were associated with at least two different biovars. Campylobacter jejuni biovar I was predominant in humans, sheep and chickens and Campylobacter coli biovar I in pigs. The results suggest that the combined use of bio-and serotyping according to the Lior typing schemes would be of use in studies on the epidemiology of human campylobacteriosis in Germany.
