Encapsulated Haemophilus influenzae type b produce nonencapsulated variants at high frequency (0.1-0.3%). Cosmid cloning was used to investigate the genetic mechanism responsible for this instability. Analysis of three independently derived cosmid clones showed that the b+ parental strain contains an 18-kilobase tandem duplication of genes involved in type b capsule expression. Loss of one comp...
Necrotizing fasciitis caused by Haemophilus influenzae type b is a rare infection of the skin and soft tissues. The only previously reported case involved a healthy infant. We report herein the case of an 81-year-old Japanese woman with diabetes mellitus who developed necrotizing fasciitis caused by H. influenzae type b.
In vitro, Haemophilus influenzae strains have two distinct patterns of susceptibility to trimethoprim-sulfamethoxazole (TMP/SMZ); strains with low minimum inhibitory concentration and high minimum bactericidal concentration (tolerant) and those with both low minimum inhibitory concentration and minimum bactericidal concentration (kill-sensitive). Tolerant H. influenzae strains were found to ela...
The Editorial by Lone and Puliyel contains several factual errors. It exhibits a time warp, citing old information but not its new details and a disregard for truth by arguments taken out of context. It contains statements that have been disproved. The idea of pentavalent vaccine has ‘technical’ elements – the epidemiological need to introduce hepatitis B (HB) vaccine and Haemophilus influenzae...
A retrospective database review showed that Haemophilus influenzae type b conjugate vaccine decreased the annual number of cases of H. influenzae type b meningitis in children in Blantyre, Malawi. Among young bacterial meningitis patients, HIV prevalence was high (36.7% during 1997-2009), and pneumococcus was the most common etiologic agent (57% in 2009).
Surveillance for Haemophilus influenzae meningitis cases was performed in Salvador, Brazil, before and after introduction of H. influenzae type b (Hib) immunization. The incidence of Hib meningitis decreased 69% during the 1-year period after initiation of Hib immunization (from 2.62 to 0.81 cases/100,000 person-years; P<.001). In contrast, the incidence for H. influenzae type a meningitis incr...
To identify adults who may be at risk for Haemophilus influenzae type b disease by virtue of low levels of antibody against the H. influenzae b capsule and who may thus benefit from receiving H. influenzae b vaccine, we correlated serum anticapsular antibody levels of 388 adult patients with 26 health-related variables, including 3 personal characteristics, 10 laboratory values, 4 drug use cate...
