Reassortment of bluetongue virus vaccine serotypes in cattle
… double stranded (ds) RNA genome and currently 27 serotypes have been identified worldwide. The virus is transmitted by Culicoide biting midges (Diptera: Ceratoponidae) and the occurrence of the disease depends on the presence and abundance of competent vectors. In South Africa most European ovine …

Aggregatibacter actinomycetemcomitans serotypes in gingival crevicular fluid of mothers delivering preterm.
… of Aggregatibacter actinomycetemcomitans (Aa) serotypes in gingival crevicular fluid (GCF) stored for more than ten years could be used as microbial biomarkers to predict preterm delivery. The study samples included 185 samples from “preterm birth” and “normal birth” mothers with pregnancy …

Chemical and spectroscopic studies of the capsular polysaccharides of some Klebsiella serotypes
… serotype K71 has been investigated, and that of serotypes K36 and K64 re-examined, by novel enzymic and spectroscopic methods. The cultivation and employment of bacteriophages which are capable of cleaving (by specific glycanase action) the isolated, cognate bacterial polysaccharide in vitro has …

Structural analysis of capsular polysaccharides produced by some emerging Klebsiella pneumoniae serotypes
… up to 77 known distinct K. pneumoniae K-antigen serotypes, that have been classified through serotyping. Furthermore, there are additional K-locus (KL) serotypes that have been recently identified using genotyping. This project involved the characterisation and structural elucidation of the CPS …

Force field comparison through computational analysis of capsular polysaccharides of Streptococcus pneumoniae serotypes 19A and F
… under five. While there are over 90 pneumococcal serotypes only a handful of these are responsible for disease. Immunisation with the conjugate vaccine PCV7, has markedly decreased invasive pneumoccocal disease. Following PCV7 immunisation, incidences of non-vaccine serotypes, especially …

Detection of Actinobacillus Pleuropneumoniae and Identification of Serotypes 1, 2, and 8 by Multiplex Polymerase Chain Reaction
… problematic due to cross- reactivity between serotypes, particularly serotypes 6 and 8. To avoid these serological cross-reactions, a multiplex PCR assay was developed to detect A. pleuropneumoniae and identify serotypes 1, 2, and 8. Primers specific to the conserved capsular polysaccharide …

Biochemical Studies of EA22, A Protein Involved in The Bacteriophage Lysogenic-Lytic Decision and the Virulence of Clinically Relevant Serotypes of E. Coli
Enterohemorrhagic Escherichia coli (EHEC) infections are associated with short term gastrointestinal problems, but in some cases, it can lead to more life-threatening conditions. The pathogenicity of EHEC Is supported by an endogenous, dormant bacteriophage that persists in the bacterium as a …

Characterization of the type VI protein secretion system encoded in the Salmonella pathogenicity island 19 and its role in the pathogenicity of serotypes Gallinarum and Enteritidis
El genero Salmonella comprende a mas 2,500 serotipos conocidos distribuidos en dos especies: enterica y bongori. Estos serotipos difieren mucho en términos de patogenicidad y especificidad hospedero. Dos serotipos de Salmonella entérica son de especial relevancia: los serotipos Gallinarum y …

Genetic Studies of the Effect of Serotype Switching in O1 Vibrio cholerae
… pathogenic bacteria presents as two main serotypes: Ogawa and Inaba. The serotypes differ in the methylation of a surface sugar that is mediated by the wbeT gene, with Ogawa having an active intact gene and Inaba having an inactive mutated gene, giving loss-of-function. The aim of this …

Trends in the Incidence of Culture-Confirmed Human Salmonellosis Reported in Virginia During 2012-2022
… trends nationally. Of the187 total Salmonella serotypes reported in Virginia during 2012-2022, 64% of culture-confirmed cases were attributable to six serotypes: Typhimurium/I 4,[5],12:i:- (20%), Enteritidis (18%), Newport (11%), and Javiana (8%), Bareilly (4%), and Braenderup (4%). The …

A pan-genome wide association study to identify genes associated with invasive Streptococcus pneumoniae
… samples). In-silico serotyping identified 56 serotypes in the cohort and statistical analysis showed that despite the vaccination, the prevalence of serotypes 1 and 12F increased amongst patients. Genomes were assembled, and a reference pan-genome for all strains was built. Short reads were …

CHARACTERISTICS OF CLINICAL NONTYPHOIDAL SALMONELLA ISOLATES FROM A HISTORICAL BIOBANK WITH A FOCUS ON THE INVASIVE SEROTYPE CHOLERAESUIS, LOMBARDY REGION (2001-2016)
… to invasive systemic disease. While typhoidal serotypes are well recognized as agents of enteric fever, a subset of nontyphoidal serotypes also displays an unusually high invasiveness index, posing a major challenge for surveillance and control. In this context, analyses of historical biobanks …

Modelling the ecology and epidemiology of Streptococcus pneumoniae and their impact on conjugate vaccination
… understanding of the ecology of the pneumococcal serotypes. Statistical models are employed to analyse the changes in post vaccination epidemiology in the UK in both carriage and invasive disease and to correct for possible ascertainment biases. Established mathematical models are analysed for …

Novel strategies to prevent and treat experimental pneumococcal disease
With over 90 different serotypes of Streptococcus pneumoniae unevenly distributed around the world, current vaccine formulations vary significantly in their ability to protect against invasive pneumococcal disease (IPD). The adult pneumococcal vaccine is composed of capsular polysaccharide from 23 …

An evaluation of DNA fingerprinting methods for subtyping Salmonella
… have generally been shared among different serotypes, whereas IS200 profiles have tended to be more serotype-specific. AP PCR and rep-PCR primers have been shown to discriminate Salmonella isolates, but fingerprints have been more difficult to reproduce and interpret than RFLP fingerprints. …

Evaluation of a Tetravalent DNA Vaccine against Dengue: Integrating Biochemical Studies on Dengue Virus Envelope Protein to a Domain-Based Antigen Design.
… folding of the E ectodomain from all four DENV serotypes and ZIKV in mammalian cells. Our data demonstrate that E domains II and III (DII and DIII) are important for proper E folding and stabilization of soluble dimers, respectively. In addition, we show that successful covalent stabilisation of …

Characterization and differentiation of a soluble lipopolysaccharide type antigen from Treponema hyodysenteriae.
Whole cells of T. hyodysenteriae serotypes 1-7, avirulent T. hyodysenteriae serotypes 1 and 2, and 5 strains of T. innocens were chemically extracted to selectively remove a lipopolysaccharide-like substance (LPSLS). The different LPSLS were analyzed electrophoretically, immunologically, and …
