Understanding the Detection of Shiga Toxin Producing Escherichia Coli: Virulence Factors, Pathogenicity Islands or Serotypes?
(Biomedical Research Network, 2018-03)
Shiga toxin-producing Escherichia coli (STEC) are important food borne pathogens that can cause severe disease in children by producingtwo toxins (Stx1 and Stx2). This bacteria harbor several additional virulence factorsand ...
Pneumococcal lineages associated with serotype replacement and antibiotic resistance in childhood invasive pneumococcal disease in the post-PCV13 era: an international whole-genome sequencing study
(Elsevier Science Inc, 2019-07)
Background: Invasive pneumococcal disease remains an important health priority owing to increasing disease incidence caused by pneumococci expressing non-vaccine serotypes. We previously defined 621 Global Pneumococcal ...
Prevalence, serotypes and virulence genes of streptococcus agalactiae isolated from pregnant women with 35–37 weeks of gestation
(BioMed Central, 2021-12-30)
Background: In pregnant women Streptococcus agalactiae (GBS) can be transmitted to newborn causing severe infections. It is classified into 10 serotypes (Ia, Ib, II-IX). The severity of neonatal disease is determined by ...
Population genetic structure, serotype distribution and antibiotic resistance of Streptococcus pneumoniae causing invasive disease in children in Argentina
(Microbiology Society, 2021-09)
Invasive disease caused by Streptococcus pneumoniae (IPD) is one of the leading causes of morbidity and mortality in young children worldwide. In Argentina, PCV13 was introduced into the childhood immunization programme ...
Detection and characterization of Salmonella Serotypes in the production chain of two pig farms in Buenos Aires Province, Argentina
(Frontiers Research Foundation, 2018-06)
The aim of the present study was to determine the prevalence of Salmonella in the pork production chain and to characterize Salmonella isolates. From 764 samples, 35 (4.6%) were positive for Salmonella spp., as determined ...
Differences in the virulence of two strains of Foot-and-Mouth Disease Virus Serotype A with the same spatiotemporal distribution
(Elsevier, 2010-01)
During the 2000–2001 epidemic of Foot-and-Mouth Disease Virus (FMDV) in Argentina, two FMDV serotype A viruses were identified among others. Since different pathogenic properties between these virus strains were noticed ...
Streptococcus suis serotype 2 strains isolated in Argentina (South America) are different from those recovered in North America and present a higher risk for humans
(2016-10)
Introduction: Streptococcus suis serotype 2 is an important swine pathogen and emerging zoonotic agent causing meningitis and septicemia/septic shock. Strains are usually virulent (Eurasia) or of intermediate/low virulence ...
Simple production of hydrophobin-fused domain III of dengue envelope protein and induction of neutralizing antibodies against the homotypic serotype of dengue virus
(Springer, 2019-12)
Hydrophobin-fused domain III of dengueenvelope proteins serotypes 1 and 2 were expressed inRachiplusia nu larvae and purified by aqueous twophasesystem. This biotechnological approach ofhydrophobin-fused proteins, which ...
Presencia de serotipos de Campylobacter jejuni O:19 en la cadena avícola Argentina = Campylobacter jejuni O:19 serotype in Argentine poultry meat supply chain
(2017-06)
Las especies termotolerantes de Campylobacter han tomado gran relevancia en los últimos años debido a que son los principales agentes zoonóticos causantes de enfermedades transmitidas por alimentos. Adicionalmente, ...
Dissemination of an erythromycin-resistant penicillin-nonsusceptible streptococcus pneumoniae Poland6B-20 clone in Argentina
(Mary Ann Liebert, 2011-03)
Prevalence of serotype 6B penicillin (PEN)-nonsusceptible Streptococcus pneumoniae significantly increased from 15.8% (1993-1997) to 67.3% (1998-2002) (p < 0.001) in Argentina. Serogroup 6 ranks fourth among different ...
