Six new serovars of Leptospira interrogans were isolated from opossums (Didelphis marsupialis and Philander opossum) trapped in the Peruvian jungle. The proposed names, type strain designation, and serogroup of the serovars, respectively, were: huallaga, strain M-7, Djasiman serogroup; luis, strain M-6, Tarassovi serogroup; machiguenga, strain MMD-3, Icterohaemorrhagiae serogroup; rioja, strain...

Context Although cases of Neisseria meningitidis serogroup A (NmA) in the African meningitis belt have declined dramatically following the extensive roll-out of MenAfriVac, a monovalent serogroup A conjugate vaccine, outbreaks due to other meningococcal serogroups have continued.1 More than 25 000 suspected cases of meningitis across the meningitis belt have been reported in each of the past 3 ...

in recent years, the importance of shigella as an enteric pathogen with global impact has been increasingly recognized. in this study, serogroup distribution of shigella isolated from clinically diagnosed cases of gastroenteritis and acute diarrhea in tehran, capital of iran was investigated between december 2002 and november 2003. fecal specimens and rectal swabs were cultured for shigella spp...

background and objectives: rapid clinical manifestation/progression of the meningococcal meningitis and lacunae in conventional bacteriological test often encourages indiscriminate use of antibiotics much before the etiology is established. this study was planned to evaluate ctra pcr for rapid molecular detection. in addition, multiplex pcr and sequencing was done for serogroup prediction to pr...

Here, we report the first complete genome sequence of Anopheles A virus (ANAV) that was isolated from Colombia in 1940, and we include the first description of the medium and large segments. The ANAV medium and large segments share the highest identity with serogroup member Lukuni virus, which causes human infection.

BACKGROUND We investigated serological correlates of protection against Neisseria meningitidis serogroup A (NmA) in Burkina Faso before the introduction of NmA conjugate vaccine. METHODOLOGY/PRINCIPAL FINDINGS We collected blood from a representative sample (N = 1022) of Bobo-Dioulasso residents. Sera were evaluated for serum bactericidal antibody (SBA) activity against NmA strains of immunot...

Meningococcal serogroup-specific immunoglobulin G (IgG), IgG1, and IgG2 concentrations were assigned to three reference sera, CDC 1992, 89-SF, and 96/562, for meningococcal serogroups A, C, Y, and W135 via the method of cross standardization. The sum of the serogroup-specific IgG1 and IgG2 concentrations determined for the four meningococcal serogroups showed good agreement with the serogroup-s...

The data on serovar distributions of Chlamydia trachomatis - the most diagnosed sexually transmitted infection (STI) worldwide - are important for epidemiologic purposes and transmission studies but are completely lacking in Russia. The aim of the current study is to determine the serogroup and serovar distributions in Russian men and women and compare these data with Dutch serogroup and serova...

Invasive meningococcal disease (IMD) caused by Neisseria meningitidis serogroup Y has increased in Europe, especially in Scandinavia. In Sweden, serogroup Y is now the dominating serogroup, and in 2012, the serogroup Y disease incidence was 0.46/100,000 population. We previously showed that a strain type belonging to sequence type 23 was responsible for the increased prevalence of this serogrou...

Non-culture diagnosis and serogroup determination of meningococcal infection is important in contact management where vaccination may be possible. A serogroup B and C PCR ELISA assay for the non-culture diagnosis and serogroup determination has proved invaluable for enhanced epidemiological surveillance and contact management. A polymerase chain reaction assay, based on a restriction fragment l...
