Identification of Capsular Serotypes K1 and K2 in Clinical Isolates of Klebsiella Pneumoniae in North of Iran
ABSTRACT Background and Objectives: Klebsiella pneumoniae is one of the most important nosocomial pathogens. Its capsular polysaccharide is considered as the first and most important virulence factor of this bacterium. This study aimed to investigate the presence of capsular serotypes K1 and K2 in K. pneumoniae isolates to examine the virulence ...
متن کاملClinical spectrum and molecular characteristics of Klebsiella pneumoniae causing community-acquired extrahepatic abscess.
BACKGROUND AND PURPOSE Klebsiella pneumoniae causes a wide spectrum of infections, including abscess and non-abscess formation. This study investigated the clinical spectrum and molecular characteristics of community-acquired Klebsiella infection with primary extrahepatic abscess. METHODS From April 2004 through March 2007, a total of 18 strains of K. pneumoniae, 11 from blood and 7 from foca...
متن کاملKlebsiella pneumoniae Bacteremia and Capsular Serotypes, Taiwan
Capsular serotypes of 225 Klebsiella pneumoniae isolates in Taiwan were identified by using PCR. Patients infected with K1 serotypes (41 isolates) had increased community-onset bacteremia, more nonfatal diseases and liver abscesses, lower Pittsburgh bacteremia scores and mortality rates, and fewer urinary tract infections than patients infected with non-K1/K2 serotypes (147 isolates).
متن کاملImpact of age on neutrophil phagocytic reaction with different capsular serotypes of Klebsiella pneumoniae.
BACKGROUND Although the prevalence of K pneumoniae liver abscess is higher in patients older than 55 years, the possible relationship of age with decreased phagocytic function of the patients with Klebsiella pneumoniae liver abscess has not been investigated. Our aim was to determine whether susceptibility to K pneumoniae infection depended on age-related impairment of phagocytic function. ME...
متن کاملThe function of wzy_K1 (magA), the serotype K1 polymerase gene in Klebsiella pneumoniae cps gene cluster.
In this issue of the Journal, Yeh et al [1] revisit the importance of magA in Kleb-siella pneumoniae causing pyogenic liver abscess, as well as its exact role in serotype K1 capsule formation. The mucoviscosity-associated gene A (magA) of K. pneumo-niae was originally discovered in 2002 by me and my colleagues [2, 3] in tissue-invasive K. pneumoniae strains causing primary liver abscess complic...
