Introduction : Haemophilus influenzae is a gram-negative bacterium causing a variety of respiratory infections in developing countries, especially in children. Nasopharynx carriers of H. influenzae are the prominent source and transitional vectors of invasive diseases. As very limited information on H. influenzae carriage rate in Iran was available, an evaluation on prevalence of this bacteri...

background: haemophilus influenzae type b (hib) has emerged as the predominant cause of meningitis in developing coun­tries wherever it has been studied using good microbiologic procedures, but data  regarding frequency, antimicrobial sus­ceptibility and preferable method for detection of haemophilus influenzae type b isolated from  iranian patients  were scarce. methods: one thousand and eight...

Introduction: Based on the World Health Organization reports, infections caused by ampicillin-resistant Haemophilus influenzae strains are a major threat to public health and need urgent therapy with new antibiotics. Given the lack of a previous comprehensive study on the prevalence of the antibiotic resistance of H. influenzae in Iran, this systematic review and meta-analysis was perform...

objective: bacterial meningitis is a dangerous and sometimes fatal infection that affects the central nervous system. because some antibiotics can prevent some types of these bacteria and supress them from spreading and infecting, therefore it is important to know what type of virus or bacterium is causing meningitis. haemophilus influenzae and neisseria meningitides are the two main pathogens...

Filter matings between E. coli K-12 strains carrying an F'::Tn5,Tn9 factor with H. influenzae Rd strains gave rise to kanamycin-chloramphenicol-resistant H. influenzae strains at a frequency of approximately 10(-6). Transfer of the F' factor to H. influenzae was verified by expression of unselected markers in H. influenzae (lac+ or cotransfer of the nonselected antibiotic resistance), physical ...

Thirty-eight clinical isolates of nontypeable Haemophilus influenzae were tested for the presence of hemagglutinating pili similar to those of H. influenzae type b (Hib) that mediate buccal epithelial cell adherence. Four endogenously hemagglutinating (HA+) strains were identified, and eight additional HA+ variants were obtained from HA- strains by erythrocyte enrichment. All 12 HA+ nontypeable...

such as sepsis and meningitis, has declined substantially since the introduction of the H. influenzae serotype b vaccine. However, the H. influenzae type b vaccine fails to protect against nontypeable H. influenzae strains, which have become increasingly frequent causes of invasive disease, especially among children and the elderly. We summarize recent literature supporting the emergence of inv...
