Introduction: Haemophilus influenza is a type of bacterium that non motile, gram negative and causes poisoning infection including pneumonia,bronchitis etc. In order to study the resistivity H.influenza protein, transcription regulator: HI0433, homology modeling an important step predict structure. Material methods: Bioinformatics such as CMR, BLAST, modeller Prcheck Prosa was carried out find ...

By a simple procedure, using a readily reproducible medium, most strains of H. influenzae can be stored for four weeks or more and can be sent through the post. Capsulate strains can be stored in this way without apparent change.

A chemically defined medium (MI(c)) is described in which cells of Haemophilus influenzae Rd grow rapidly (generation time, 35 +/- 5 min) and reach a stationary level of 10(10) cells/ml. Our strain of cells grown in this medium developed high levels of competence when transferred to another medium designed for that purpose. Conditions governing the total development of competence in this organi...

UV-irradiated plasmid pNov1 containing a cloned fragment of chromosomal DNA could be repaired by excision, but plasmid p2265 without homology to the chromosome could not. Establishment of pNov1 was more UV resistant in Rec(-) than in Rec(+) cells.

Pasteurella multocida appears to be a very rare cause of meningitis. The bacterium has morphological similarities with other causative organisms, particularly Haemophilus influenzae, and its apparent rarity may be due partly to misidentification. This case, only the fourth reported from the United Kingdom, could not be distinuished clinically from the meningitis, owing to other pyogenic bacteria.

A simple haemagglutination procedure is described which measures antibodies that react with capsular antigens of Haemophilus influenzae. Abnormally high antibody titres of appropriate type-specificity are common in the blood of human subjects who are known to have carried capsulate strains of H. influenzae. It is not yet clear whether all such antibodies are due to such carriage.

prospective sentinel surveillance for Haemophilus influenzae B (Hib) meningitis1. The National Technical Advisory Group on Immunization (NTAGI) in its meeting of August 26, 2010 recommended that pentavalent vaccine containing Hib be introduced in the States of Kerala and Tamil Nadu2. Since there was concern about its adverse effects (AEFI), this was to be monitored in the two States. Further ro...

We analyzed national Haemophilus influenzae (Hi) surveillance data from 1994 and 1995 to describe the epidemiology of Hi invasive disease among persons of all ages. Serotype data were available for 376 (56%) of 669 reported Hi cases among children aged 4 years or younger; 184 (49%) were H. influenzae type b (Hib). Among children aged 4 or younger, incidence (per 100,000) of all Hi invasive dise...

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...
