“…5 Distribution of epidemiological groups of S. Choleraesuis strains according to their place of origin and III. In case of S. Choleraesuis, biochemical characterisation may also be used as tool for further phenotypical discrimination (Le Minor et al 1985). Not only the differentiation between the biovar Choleraesuis sensu stricto or variato Choleraesuis (H 2 S negative) and the biovar Kunzendorf (H 2 S positive) but also the differences in their fermentation patterns for sorbitol, melibiose and arabinose allowed an additional discrimination of the macrorestriction groups in altogether five epidemiological groups.…”

Salmonella enterica subspecies enterica serovar Choleraesuis in a wild boar population in Germany

Salmonella (S.) enterica subspecies enterica serovar Choleraesuis, the swine-adapted serovar is found rarely in Western European countries including Germany. However, the regional laboratory of the federal state Thuringia in Germany examined diseased wild boars routinely also for the occurrence of Salmonella organisms. Between 2006 and 2008, only the serovar S. Choleraesuis was islolated from 24 animals, three strains isolated from domestic pigs were included. In order to detect a possible epidemiological context, the strains of S. Choleraesuis were characterised by macrorestriction and plasmid analysis, repetitive sequence PCR, antimicrobial testing and determining the biochemical profile. A combination of all methods enabled the identification of five epidemiological groups. Two groups were detected in the same territory but three other discriminative groups were predominant in different regions. S. Choleraesuis strains of the different epidemiological groups circulate in wild boar populations in the corresponding regions. However, it could be concluded that both natural barriers like mountains and artificial barriers like arterial roads may cause the separation of wild boar populations and as a result also the respective S. Choleraesuis organisms. The occurrence of the identical epidemiological groups in wild boars and domestic pigs indicates the possible mutual exposure of the pathogen. To avoid risks for human and domestic pig health regular inspection of meat from wildlife by official veterinarians and advice of hunters and persons who prepare and consume wild boar meat should be enhanced.

Host adapted serotypes of Salmonella enterica

et al. 2000

Salmonella constitutes a genus of zoonotic bacteria of worldwide economic and health importance. The current view of salmonella taxonomy assigns the members of this genus to two species: S. enterica and S. bongori. S. enterica itself is divided into six subspecies, enterica, salamae, arizonae, diarizonae, indica, and houtenae, also known as subspecies I, II, IIIa, IIIb, IV, and VI, respectively [1]. Members of Salmonella enterica subspecies enterica are mainly associated with warm-blooded vertebrates and are usually transmitted by ingestion of food or water contaminated by infected faeces. The pathogenicity of most of the distinct serotypes remains undefined, and even within the most common serotypes, many questions remain to be answered regarding the interactions between the organism and the infected host.Salmonellosis manifests itself in three major forms: enteritis, septicaemia, and abortion, each of which may be present singly or in combination, depending on both the serotype and the host involved. Although currently over 2300 serovars of Salmonella are recognized, only about 50 serotypes are isolated in any significant numbers as human or animal pathogens [2, 3] and they all belong to subspecies enterica. Of these, most cause acute gastroenteritis characterized by a short incubation period and a severe systemic disease in man or animals, characterized by septicaemia, fever and/or abortion, and such serotypes are often associated with one or few host species [4–6].It is the intention of this review to present a summary of current knowledge of these host-adapted serotypes of S. enterica. The taxonomic relationships between the serotypes will be discussed together with a comparison of the pathology and pathogenesis of the disease that they cause in their natural host(s). Since much of our knowledge on salmonellosis is based on the results of work on Typhimurium, this serotype will often be used as the baseline in discussion. It is hoped that an appreciation of the differences that exist in the way these serotypes interact with the host will lead to a greater understanding of the complex host–parasite relationship that characterizes salmonella infections.

“…To test the possibility that they were H # S-negative Cs-Kunz we submitted them to the WHO Salmonella Research and Reference Laboratory, Institut Pasteur, Paris. These two strains gave the reactions with adsorbed anti-c sera characteristic of Cs-Kunz, not those of Cs-non K [4] (Dr M. Y. Popoff, personal communication). All 26 Cs-Kunz strains gave moderate to heavy growth after 1, or at most 2 days incubation of simple defined medium with a heavy streak inoculum.…”

Application of ribotyping and IS200 fingerprinting to distinguish the five Salmonella serotype O6,7[ratio ]c[ratio ]1,5 groups: Choleraesuis sensu stricto, Choleraesuis var. Kunzendorf, Choleraesuis var. Decatur, Paratyphi C, and Typhisuis

Sixty-seven strains of the five described Salmonella serotypes having antigens 6,7[ratio ]c[ratio ]1,5, that is S. enterica serotype Choleraesuis sensu stricto, Choleraesuis var. Kunzendorf, Choleraesuis var. Decatur, Paratyphi C, and Typhisuis, were examined for 16S rrn profile ribotype, presence of IS200 and phenotypic characters, including rate of change of flagellar-antigen phase and nutritional character. Choleraesuis sensu stricto and its Kunzendorf variant had related but distinct ribotypes. Therefore, ribotyping appears to be a suitable method for differentiating Choleraesuis non-Kunzendorf from Choleraesuis var. Kunzendorf. Some strains of Paratyphi C had 16S profiles that resembled that of Choleraesuis non-Kunzendorf, while others resembled that of Choleraesuis var. Kunzendorf. The Typhisuis profiles were like those of Choleraesuis non-Kunzendorf, while the Choleraesuis var. Decatur profiles were unlike those of any of the other four groups. Furthermore, IS200 fingerprinting discriminated between Choleraesuis var. Decatur and the other strains with antigenic formula O6,7[ratio ]c[ratio ]1,5, and comparison of IS200 patterns showed a high degree of genetic divergence within Choleraesuis var. Decatur. Our findings show that ribotyping and IS200 fingerprinting, combined with classical microbiological methods, distinguish the groups Choleraesuis non-Kunzendorf, Choleraesuis var. Kunzendorf, Choleraesuis var. Decatur, Paratyphi C and Typhisuis.
