Twenty bacterial strains isolated from the blood of patients with suspected Streptococcus suis infection based on clinical symptoms in northern Thailand between 2009 and 2010 were subjected to phenotypic and genotypic identification. Commercial identification kits and a PCR-based assay targeting the S. suis-specific 16S rDNA sequence correctly identified S. suis isolated from patients in northern Thailand; however, there was a risk of misidentifying S. gallolyticus as S. suis using a PCR assay targeting the S. suis-specific house keeping gene encoding glutamate dehydrogenase. This is the first paper to report S. gallolyticus infection in humans in Thailand.

    • "MLST has been successful in the characterization of several bacteria including other streptococcal species (Dingle et al., 2001; Enright & Spratt, 1998; King et al., 2002). For example, it has been reported that highly virulent clones of Streptococcus suis, a species very similar to S. gallolyticus (Tien et al., 2012) were revealed by MLST (King et al., 2002). "

    ABSTRACT: Streptococcus gallolyticus is often found as a member of the normal gut microflora in various animals. However, it has been reported to cause mastitis in cattle; septicemia in pigeons; and meningitis, septicemia, and endocarditis in humans. However, little is known about the epidemiology and crucial virulence factors of S. gallolyticus. To help address these issues, we developed a multilocus sequence typing (MLST) scheme for S. gallolyticus. Seven housekeeping gene fragments were sequenced from each of the 58 S. gallolyticus isolates collected from diverse origins and sources. The MLST scheme had good discriminatory ability. The 63 strains including the 5 whole sequenced strains examined resolved into 57 sequence types (STs), with 52 STs represented by only a single strain. With respect to the identification of S. gallolyticus subspecies (i.e., S. gallolyticus subsp. gallolyticus, S. gallolyticus subsp. pasteurianus, and S. gallolyticus subsp. macedonicus), the results of biochemical tests and DNA-DNA hybridization were in high concordance with those of the MLST scheme. The MLST scheme developed in this study may be a useful tool capable of replacing the conventional methods used for S. gallolyticus subspecies identification. The results of this study suggest that the biology and virulence of two pathogenic S. gallolyticus subspecies (i.e., S. gallolyticus subsp. gallolyticus and S. gallolyticus subsp. pasteurianus) are very different. The MLST scheme offers researchers a valuable typing tool that will promote further investigation of the epidemiology of S. gallolyticus.

    ABSTRACT: First International Workshop on Streptococcus suis, Beijing, China, 12-13 August 2013 The first international workshop on Streptococcus suis, which is an important swine pathogen and emerging zoonotic agent, took place in Beijing, jointly organized by the Faculty of Veterinary Medicine, University of Montreal, Canada and the National Institute for Communicable Disease Control and Prevention, China CDC. The aim of the meeting was to gather together, for the first time, more than 80 researchers working on S. suis, from countries including China, Canada, Japan, The Netherlands, Germany, Thailand, the UK and Vietnam. This article, the first of a two-part report on this First International Workshop, reviews current aspects of the epidemiology and population genomics of S. suis, covers public health concerns and discusses questions about S. suis serotyping and molecular diagnostics.

    ABSTRACT: Streptococcus suis is an important pathogen causing economic problems in the pig industry. Moreover, it is a zoonotic agent causing severe infections to people in close contact with infected pigs or pork-derived products. Although considered sporadic in the past, human S. suis infections have been reported during the last 45 years, with two large outbreaks recorded in China. In fact, the number of reported human cases has significantly increased in recent years. In this review, we present the worldwide distribution of serotypes and sequence types (STs), as determined by multilocus sequence typing, for pigs (between 2002 and 2013) and humans (between 1968 and 2013). The methods employed for S. suis identification and typing, the current epidemiological knowledge regarding serotypes and STs and the zoonotic potential of S. suis are discussed. Increased awareness of S. suis in both human and veterinary diagnostic laboratories and further establishment of typing methods will contribute to our knowledge of this pathogen, especially in regions where complete and/or recent data is lacking. More research is required to understand differences in virulence that occur among S. suis strains and if these differences can be associated with specific serotypes or STs.
