Fiji recently experienced a sharp increase in reported typhoid fever cases. To investigate geographic distribution and environmental risk factors associated with Salmonella enterica serovar Typhi infection, we conducted a cross-sectional cluster survey with associated serologic testing for Vi capsular antigen-specific antibodies (a marker for exposure to Salmonella Typhi in Fiji in 2013. Hotspo...
Salmonella enterica consists of over 2,000 serovars that are major causes of morbidity and mortality associated with contaminated food. Despite similarities among serovars of Salmonella enterica, many demonstrate unique host specificities, epidemiological characteristics, and clinical manifestations. One of the unique epidemiological characteristics of the serovar Enteritidis is that it is the ...
174 Emerging Infectious Diseases • www.cdc.gov/eid • Vol. 11, No. 1, January 2005 6. Giraud E, Brisabois A, Martel JL, ChaslusDancla E. Comparative studies of mutations in animal isolates and experimental in vitroand in vivoselected mutants of Salmonella spp. suggest a counterselection of highly fluororquinolone-resistant strains in the field. Antimicrob Agents Chemother. 1999;43:2131–7. 7. Hir...
Abstract Salmonella enterica serovar Typhi and Paratyphi have been imputed in the causation of enteric fever. Cardiovascular extraintestinal infections documented among immunocompromised individuals. Rarely these pathogens are ascribed immunocompetent hosts due to hematogenous seeding. We report a case anterior chest wall abscess with osteomyelitis an adult by paratyphi A without any prior pred...
The genus Salmonella consists of over 2,200 serovars that differ in their host range and ability to cause disease despite their close genetic relatedness. The genetic factors that influence each serovar's level of host adaptation, how they evolved or were acquired, their influence on the evolution of each serovar, and the phylogenic relationships between the serovars are of great interest as th...
Among enteric pathogens, Salmonella enterica serovar Typhi is responsible for the largest number of food-borne outbreaks and fatalities. The ability of the pathogen to cause systemic infection for extended durations leads to a high cost of disease control. Chronic carriers play important roles in the evolution of Salmonella Typhi; therefore, identification and in-depth characterization of isola...
Introduction: Latin American countries have public health problems that are aggravated by inadequate basic sanitary conditions. Inefficient vaccination coverage, as well the fact a significant portion of population is exposed to contaminated water and food, can lead an increase in incidence some diseases. Methodology: work reports case infection Salmonella enterica serovar Typhi (S. Typhi), who...
The tol-pal genes are essential for maintaining the outer membrane integrity and detergent resistance in various Gram-negative bacteria, including Salmonella. The role of TolA has been well established for the bile resistance of Salmonella enterica subsp. enterica serovar Typhimurium. We compared the bile resistance pattern between the S. enterica serovars Typhi and Typhimurium and observed tha...
Proteins exhibiting hyper-variable sequences within a bacterial pathogen may be associated with host adaptation. Several lineages of the monophyletic pathogen Salmonella enterica serovar Typhi (S. Typhi) have accumulated non-synonymous mutations in the putative two-component regulatory system yehUT. Consequently we evaluated the function of yehUT in S. Typhi BRD948 and S. Typhimurium ST4/74. Tr...
