Department of Pathology, Singapore General Hospital.

Serogrouping of 506 Shigella strains isolated in Singapore from 1986 to 1990 showed that Shigella flexneri (60.3%) was the most common, followed by S. sonnei (33.6%), S. boydii (3.2%) and S. dysenteriae (3%). Of the 23 Shigella serotypes identified, the predominant ones were S. flexneri types 2a and 1b, S. boydii types 1 and 5, and S. dysenteriae types 1 and 3. More than 80% of the Shigella species were resistant to at least one antimicrobial drug, and the incidence of multiresistance was particularly high in S. flexneri strains. Due to the high incidence of antimicrobial resistance, the susceptibility pattern of Shigella strains should be determined for treatment purposes.

UI	MeSH Term	Description	Entries
D004352	Drug Resistance, Microbial	The ability of microorganisms, especially bacteria, to resist or to become tolerant to chemotherapeutic agents, antimicrobial agents, or antibiotics. This resistance may be acquired through gene mutation or foreign DNA in transmissible plasmids (R FACTORS).

D004405	Dysentery, Bacillary	DYSENTERY caused by gram-negative rod-shaped enteric bacteria (ENTEROBACTERIACEAE), most often by the genus SHIGELLA. Shigella dysentery, Shigellosis, is classified into subgroups according to syndrome severity and the infectious species. Group A: SHIGELLA DYSENTERIAE (severest); Group B: SHIGELLA FLEXNERI; Group C: SHIGELLA BOYDII; and Group D: SHIGELLA SONNEI (mildest).

D012703	Serotyping	Process of determining and distinguishing species of bacteria or viruses based on antigens they share.	Serotypings
D012761	Shigella boydii	One of the SHIGELLA species that produces bacillary dysentery (DYSENTERY, BACILLARY).
D012762	Shigella dysenteriae	A species of gram-negative, facultatively anaerobic, rod-shaped bacteria that is extremely pathogenic and causes severe dysentery.
