Prevalence and Susceptibility Pattern of Streptococcus suis at Maharat Nakhon Ratchasima Hospital
Streptococcus suis infection is a cause of meningitis, septicemia and hearing loss. Infected patients need to be treated as fast as possible to decrease the mortality rate, Previous report has shown a high prevalence of Streptococcus suis infection in northern Thailand. The incidence of this infection has been increasing in all regions of Thailand. This article aimed to study the prevalence and susceptibility pattern of Streptococcus suis at Maharat Nakhon Ratchasima Hospital. The retrospective descriptive study using a five year-data (January 2012
- December 2016) collected from Microbiology Laboratory was conducted. The number of
Streptococcus suis strains reported during the year 2012 to 2016 were 36 strains (0.60%), 26 strains (0.34%), 45 strains (0.63%), 60 strains (0.75%), and 73 strains (0.76%), respectively. Mostly, the strains of Streptococcus suis were isolated from blood (75%) and cerebrospinal fluid samples. Only four strains had been isolated from other secretory samples. The majority of Streptococcus suis infection was in male individuals (78%) with average age of 58 years while the average age of infection in female was 65 years. The antimicrobial susceptibility tests showed that Streptococcus suis was susceptible to penicillin, ceftriaxone and vancomycin, The decreasing trend of susceptibility pattern of penicillin was observed (from 95% to 88%). However, penicillin is still the most effective drug used to treat Streptococcus suis infection.
