34 Haemophilus influenzae type b (Hib) strains isolated from cerebrospinal fluids (CSFs) of meningitis patients at National Hospital of Pediatrics, Hanoi, between 11/2002 and 12/2003 were biotyped, serotyped and analyzed by using PCR with specific primers, Pulsed field gel electrophoresis (PFGE) with Smal restriction enzyme. The results showed that 24 of 34 Hib strains (70.6%) belong to biotype II; 8 of 34 (23.5%) belong to biotype I. PCR patterns with capsular polysaccharide type b specified primers of the 34 Hib strains were identical. DNA restriction patterns generated by PFGE (so-called PFGE patterns) of the 34 Hib strains were mainly distributed into 2 PFGE patterns. DNA restriction patterns had close relationship to biotype. The presence of PFGE patterns of Hib strains was not related to season

Clinical characteristics and cerebrospinal fluid abnormalities in 100 cases of confirmed B type of H.influenzae (Hib) meningititis were analysed in comparing with 105 cases of meningitis caused by other bacterial pathogens. The basic criteria for early diagnosis of Hib meningitis in under five year old children were found out. Results showed that 48.8% of cases of meningititis were due to Hib; 96% of CSF samples due to Hib had physiological change in comparing with 72.4% in meningitis due to other bacterial pathogens, in 92% there were clinical manifestations and biochemical/cytological typical changes in CSF, in 100% of cases of Hib meningitis(+), there were typical changes; 51% of cases there were positive blood culture and 47% there were Hib positive CSF and blood culture concurrently

A survey conducted from 1-2/2000 in the 7 urban districts of Hanoi, Vietnam showed that overall use rate for Hib vaccine among children under 5 year of age was 3.2% and coverage for meningoccoal vaccine was 1.4%.

Haemophilus influenzae type b(Hib) is one of the most common cause of invasive bacterial disease in children. In Korea, However, the proportion occupied by Hib as a cause of pediatric pathogen is less compared to those of western countries. Natural immunity to Haemophilus influenzae type b was determined on 308 Korean children. The titration of antibody to capsular polysaccharide (PRP) was performed by the radioantigen binding assay. Forty percent of the total subjects and 31% of children under 5 years had an antibody level considered to be protective( 0.15 g/ml).Seropositivity was 13.6% in 12~17 month age group, and increased progressively to 19% in 5~10 year age group. In the age groups under 36 months of age, the geometric mean titers of anti-PRP antibody were below the protective level. These data indicate that a lot of Korean children under 5 years of age do not have antibody levels considered to be protective against H. influenzae type b, and do not explain the apparent low risk of Korean children to Hib Further studies including comparative antibody response to polysa-charide and protein antigens with other racial groups are needed.

The study was performed on 496 healthy children under five year- old age living in Hagiang and Quangninh province to discover of carrying of H.influenzae and S.pneumoniae. The results showed that: The carries with H.influenzae in Vixuyen (Hagiang) were 24% and 14.7% in Vandon (Quangninh). Ones with S.pneumoniae were 10.7% in Vixuyen (Hagiang) and 15% in Vandon (Quangninh). Antibiotic resistance level of H.influenzae in Hagiang: co-trimoxarol 34.6%, chloramphenicol 23.1%, ampicillin 7.7%; in Vandon (Quangninh): co-trimoxarol 15%, chloramphenicol 12.8%, ampixiclin 7.5%..; no one of these strains resisted to cefuroxim axetil and norfloxacin. Antibiotic resistance level of S.pneumoniae in Vixuyen (Hagiang): co-trimoxarol 17.5%, chloramphenicol 12.5%, ampixiclin 7.7%.., no one of these strains resisted to benzyn-penixiclin; In Vandon (Quangninh): co-trimoxarol 17.5%, chloramphenicol 12.5%, no one of these strains resisted to benzyn-penixiclin.

Haemophilus influenzae is one of the main pathogens of encephalitis in children less than 5 years old. The rate of ampicillin resistant strain is not high. No beta-lactamase-producing and ampicillin-resistant (BLNAR) isolates were found. The PFGE patterns of Hib isolates were highly divergent, but most could be classified into three groups (A, B and C). Hib isolates from the CSF of patients and from nasopharynges of household contacts showed the same PFGE patterns. This observation suggested that household contacts of patients are a possible reservoir of Hib.
