Immunogenicity 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...

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 کاملDETECTION OF HAEMOPHILUS INFLUENZAE TYPE B IN CEREBROSPINAL FLUID OF SUSPECTED CHILDREN WITH MENINGITIS BYPCR
ABSTRACT Background: A polymerase chain reaction (PCR) assay with primers from "hpd" gene was compared with culture for the detection of Haemophilus influenzae type b (Hib) in CSF samples from children suspected of meningitis. Methods: 300 cerebrospinal fluid (CSF) samples from suspected meningitis cases were studied by culture (Leventhal & Chocolate Agar) and PCR. Results: The latter...
متن کاملExtraction and Purification of Haemophilus influenzae Type b Lipooligosaccharide by Modified Phenol Method
Introduction : Haemophilus influenzae type b (Hib) is a Gram negative bacterium and one of the causative agents of acute bacterial meningitis, especially in infants and children less than 5 years old. Lipooligosaccharide (LOS), one of the virulence factors which plays an important role in pathogenesis of Hib, has multiple applications in diagnosis and conjugate vaccines. In this study, LOS ex...
متن کاملHaemophilus influenzae Type b Meningitis
The age-related acquisition of serum anticapsular and bactericidal antibodies to Haemophilus influenzae type b observed in rats was similar to that of humans. The antigenic source for this "natural" immunity was not identified, since neither pharyngeal infection with H. influenzae b nor enteric colonization by cross-reacting bacteria was detected. Infant rats surviving H. influenzae b bacteremi...
