Haemophilus Influenzae B
یکی از شایع ترین مننژیت باکتریایی در شیرخواران، هموفیلوس آنفلوانزا از نوع B (HIB) می باشد. به منظور تهیه و عرضه واکسنی جهت حفظ کودکان در مقابل این بیماری به بازار جهانی، تحقیقاتی انجام و نوعی واکسن در بخش تحقیقاتی آکسفورد مورد آزمایش و ارزیابی قرار گرفت تا در صورت تمایل والدین و کارکنان بهداشتی، تجویز همزمان آن با واکسن سه گانه و فلج اطفال عملی گردد.
متن کاملImmunogenicity and Efficacy of Different Haemophilus influenzae type b Vaccines
Haemophilus influenzae, a major cause of meningitis in young children leading to death and other neurological sequelae. The disease leaves 15 to 35% of the survivors with permanent disabilities, such as, mental retardation or deafness. Despite the availability of new and more powerful antibiotics children with Hib meningitis still suffer from high mortality or morbidity. The emergence of multir...
متن کاملParticipation of complement in host defense against encapsulated Haemophilus influenzae types a, c, and d.
Each of the serotypes of Haemophilus influenzae (types a to f) may colonize the respiratory tract of humans, but only type b strains commonly cause invasive systemic infections. To investigate the role of complement in immunity to encapsulated non-type b strains, rats were depleted of C3 with cobra venom factor and challenged with representative serotypes of H. influenzae (type a, b, c, or d) b...
متن کاملTransformation of Haemophilus influenzae.
Conjugation: Although H. influenzae genes may be transferred by plasmid-mediated conjugation, this process is not discussed further below as it has received little attention and is rarely used for strain construction. Conjugative plasmids are common in H. influenzae as in other bacteria [1, 2, 3]. The F plasmid of Escherichia coli can conjugate into H. influenzae cells [4] (and into many other ...
متن کاملUptake of heterologous DNA by Haemophilus influenzae.
With the use of highly competent Haemophilus influenzae cells, it was possible to demonstrate the uptake of heterologous DNAs. However, these DNAs, as expected, were only 1% or less as effective when competing for uptake with Haemophilus DNA. Escherichia coli DNA was removed from solution by competent cells to the extent expected if all the E. coli DNA particles contained at least one uptake re...
