Changes in serotype distribution have been described after the switch from 13-valent pneumococcal conjugate vaccine (PCV13) to 10-valent (PCV10) Belgium. To describe serotype’s invasive disease potential and detailed evolution of antimicrobial susceptibility isolates (carriage IPD) children up 30 months age over a period during (2015–2018). S. pneumoniae strains isolated nasopharynx healthy att...
Thirty-one strains of Yersinia enterocolitica were isolated from food and surface water. During the period of January 1975 to June 1977, 157 strains from 143 human cases were also isolated. Among the different serotypes from nonhuman sources, serotypes 6,30 and 4,32 were the most common. Serotype 4,32 was present only in food and not in water. Serotype 3 was isolated only from humans. Among the...
Streptococcus pneumoniae isolates of serotypes 1, 4, 6B, 7F, 14, and 19F belonging to clonal types with known invasive disease potential in humans were used to infect C57BL/6 and BALB/c mice. Most isolates were able to colonize the nasopharynx for 7 days. One serotype 19F isolate of the clonal type ST162 had higher bacterial numbers than other isolates and clonal types of the same serotype. Ser...
BACKGROUND Serotype 19A invasive pneumococcal disease (IPD) increased annually in the United States after the introduction of the 7-valent conjugate vaccine (PCV7). To understand this increase, we characterized serotype 19A isolates recovered during 2005. METHODS IPD cases during 1998-2005 were identified through population-based surveillance. We performed susceptibility testing and multilocu...
Monoclonal antibodies (MAbs) to the lipopolysaccharide (LPS) O-antigens of Campylobacter fetus serotype A and B strains were produced. Eight MAbs specific for serotype A LPS were characterized on immunoblots of C. fetus serotype A LPS. Two immunoblot patterns were observed and were used to divide the eight MAbs into two groups. MAbs M1177 and M1194 were selected as representative of the two gro...
Rabies and rabies-related virus strains were studied by using a panel of monoclonal antibodies directed against either nucleocapsid proteins or cell surface antigens of Mokola virus (Mok-3). Each strain was used in parallel to infect cultured cells and mice. Then, the patterns of reactivity of the different monoclonal antibodies were determined by the immunofluorescent-antibody staining procedu...
Conjugate vaccines protect vaccinated individuals against both disease from and nasopharyngeal carriage of Streptococcus pneumoniae and Haemophilus influenzae. Protection is specific to the capsular serotype(s) included in the vaccine. This specificity has raised concern that vaccination against particular ("targeted") serotypes may cause an increase in carriage of (and diseases attributable to...
Shigella flexneri is the major cause of bacterial shigellosis in developing countries. S. flexneri is divided into at least 19 serotypes, the majority of which are modifications of the same basic O-antigen by glucosylation and/or O-acetylation of its sugar residues by phage encoded serotype-converting genes. Recently, a plasmid encoded phosphoethanolamine (PEtN) modification of the O-antigen ha...
background: identifying regional types and evaluating the frequency of pneumococcal strains has become increasingly important especially in vaccination. the purpose of this study was the identification and frequency determination of our regional serotype and evaluation of the performance of recent type specific multiplex pcr for the diagnosis of streptococcus pneumonia serotypes. methods: all i...
background and objectives: cholera is an endemic diarrheal disease in iran, caused by vibrio cholerae . the epidemiology, transmission route, environmental determinants and antimicrobial resistant pattern of cholera have been changed during recent years. in this study the epidemiology and antimicrobial resistance of cholera in iran during 2013 outbreak was investigated. materials and methods: a...
