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 کاملAlteration of coenzyme specificity of malate dehydrogenase from Streptomyces coelicolor A3(2) by site-directed mutagenesis.
We describe here for the first time the alteration of coenzyme specificity of malate dehydrogenase (MDH) from Streptomyces coelicolor A3(2) (ScMDH). In the present study, we replaced four amino acid residues in the Rossmann fold (βB-αC) region of NADH-dependent ScMDH by site-directed mutagenesis with those of NADPH-dependent MDH (Glu42Gly, Ile43Ser, Pro45Arg, and Ala46Ser). The coenzyme specifi...

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...

Bacteriol. 92:956-959. 1966.-Periodate treatment of competent cells reduced the frequency of transformation to streptomycin resistance about 90% while reducing cell viability about 30% or less. Moreover, when perio...
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 ...
