“…Two of the study organisms were isolated earlier and reported to be biochemically atypical Y. enterocolitica (2). The remaining three were recently isolated by methods described earlier (1) from patients with gastrointestinal disturbances at the University of Lagos Teaching Hospital, Lagos. The isolates were lyophilized and stored at 4°C.…”

Five Yersinia strains, biochemically mimicking Yersinia intermedia, were isolated from patients with acute diarrheal diseases seen at the University of Lagos (Nigeria) Teaching Hospital between October 1979 and September 1982. The five isolates utilized citrate as their source of carbon and fermented sucrose, L-rhamnose, and a-methyl-D-glucoside, but unlike any other Y. intermedia biogroup, they failed to ferment D-melibiose or D-raffinose. They all belonged to serogroup 0:52,53. Four autoagglutinated and were calcium dependent for growth at 37°C. Three caused conjunctivitis in the guinea pig eye model, but none possessed the 42-megadalton virulence plasmid. Four of the isolates caused diarrhea in orally infected mice and rabbits but were nonlethal for these animals. These results suggest that these isolates represent yet another Yersinia species with disease-producing capabilities in humans.

“…Animals used in the pathogenicity test were New Zealand White rabbits weighing between 600 and 800 g, obtained from the breeding stock at the National Veterinary Research Institute. The animals were observed for 1 week to ensure the absence of diarrhea, and fecal cultures were prescreened to ensure the absence of Yersinia carriage.…”

“…Yersiniosis is the third most frequent bacterial disease causing human enteric infections in Europe (Eurosurveillance-Editorial-Team, 2015), but reports on this disease are extremely non frequent in developing countries. In West Africa, only few countries reported the isolation of Yersinia from clinical cases (Simpore et al, 2009;Agbonlahor et al, 1983;Okwori et al, 2009), most likely because an active search for these bacteria is not performed. A survey of the pig reservoir in Senegal (Chambron and Bourdin, 1971) and Burkina Faso (Hakalehto et al, 2014) did not identify any Yersinia strains.…”

Pork consumption was evaluated based on transversal and retrospective survey, coupled with direct observations in Abidjan District, Côte d'Ivoire. Methods of collecting data were face-to-face interviews using standardized questionnaires for both consumers or non-consumers. In addition, Yersinia enterocolitica strains from pork samples were characterized by using biotyping, and serotyping methods as well as virulence markers. The results of the survey showed that smoked pork was consumed more (51.9%) at home, followed by fresh pork (24.7%) and then fried pork (17.3%). Outside the home, consumers preferred baked pork (51.3%). Observation of pork vendors and consumers revealed that good hygiene practices were not observed. As a result, 39.5% of consumers surveyed evoked some infection cases. The most common digestive disorders evoked were diarrhea (46.0%), abdominal pain (21.3%) and vomiting (5.2%). Thus, among the 400 samples collected, three Y. enterocolitica 4/O:3 strains were isolated, including 2 from 200 tongues and 1 strain in 200 carcasses. Y. enterocolitica 4/O:3 showed antibiotic resistances and harbored virulence genes, indicating their pathogenicity. All these findings revealed that pork consumption and processing conditions would be a risk factor for Yersinia infections. Therefore, good hygiene practices campaign along the pork chain should be conducted in Côte d'Ivoire.
