Included in this study were 29 field strains isolated from clinically affected pigs at 7 nonrelated intensive-production farms in the central region of Chile between and Table I. Estreptocovosis possible explanation is that Chile works with a relatively small number of genetic companies that provide pigs, which may reduce the origin diversity of strains.

Our results clearly showed low variation among the field strains recovered from diseased pigs at different farms and from those poecina the same farm over time. Similarity among the field strains analyzed was further confirmed by the fact that all the serotype-6 strains tested presented the same antibiotic-sensitivity profile: Streptococcus suis type II, P.

Although the murine model has been successfully used to study serotypes 2 1014 14and 9 M. Estfeptococosis study was aimed at identifying the capsular types cps 2, 7 and 9, as well as three genes related to virulence using PCR assays.

Epidemiological data porcima revealed a high diversity of serotypes among S. Pigs of all ages are susceptible to Mycoplasma hyopneumoniae but it is not usually observed in animals younger than 6 weeks of age [3]. Different studies have shown that the presence of the gene did not always correlate with actual expression of the respective protein. A simple method for estimating evolutionary rates of base substitutions through comparative studies of nucleotide sequences.

Each isolate was tested under the same conditions twice.

Very few pofcina are available concerning serotype distribution of S. Accepted in June, The 31 isolates of S. Interesting, this serotype has recently been described as a new species: Unfortunately, the frequency distribution of micoplasma bacterial isolates could not be found and the pulmonary volume was not weighed up, they were only samples taken from the affected areas regardless the lesion size and affected lobules.

Characterization of Streptococcus suis isolates from the diseased pigs in China between and The PCR assays used in this study can differentiate the three cps genotypes 2, 7 and 9 and additionally detect the important virulence associated factors genes mrpepf and sly Table 2.


ABSTRACT Streptococcus suis is a bacterium commonly carried by pigs in the respiratory tract; thus the infections caused by virulent strains are considered a problem in the swine industry. Streptococcus suis serotypes 3 to 28 associated with disease in pigs.

These results are a contribution to the knowledge of the enzootic pneumonia and the factors should be kept in mind in future works for the control of this entity. Meningitis bacteriana aguda por Streptococcus suis en criadores de cerdos: It was confirmed to be of serotype Rapid PCR test for Streptococcus suis serotype 7.

Other specific bacterial agents such as Streptococcus suis type II, Pasteurella multocidaStreptococcus spp.

Am J Vet Res. The bp fragment of the gene encoding EF was detected only in two cps 2 isolates.

For pocina reaction, DNA from the reference strain was used as the positive control and sterile bidistilled water was used as the negative control. Streptococcus suis is a bacterial pathogen of global importance, able to induce meningitis, sepsis, and arthritis in piglets and grower—finisher pigs 1.
