Virulence and molecular epidemiological analysis of three human blood-borne <i>Streptococcus suis</i>.

ABSTRACT:

Objective

To understand the virulence genes and molecular epidemiological characteristics of human-infected strains of Streptococcus suis in Rui'an, Zhejiang Province, from 2021 to 2022, and to provide a scientific basis for diagnosis, treatment, prevention, and control.

Methods

Three blood-borne strains of Streptococcus suis were analysed by morphological observation, identification, and drug sensitivity tests. We performed polymerase chain reaction (PCR) amplification of their main seven virulence factors and housekeeping genes. This was followed by virulence analysis and multilocus sequence typing. We analysed their relationships with local pathogens from previous years.

Results

Three Streptococcus suis strains were isolated from the blood samp
