blood culture isolates and antibiogram of salmonella: experience of a tertiary care hospital.enteric fevers contribute majorly to the burden of morbidity from infectious diseases in the developing world. due to growing antibiotic resistance seen in their management, salmonella and its various species are required to be periodically tested for sensitivity and resistance patterns, to guide the clinical management at the local level. this will also enable planning of antibiotic recycling wherever feasible.201627546970
case series of imported enteric fever at a referral center in tokyo, japan: antibiotic susceptibility and risk factors for relapse.owing to the increase in salmonella strains with decreased fluoroquinolone susceptibility in the endemic areas, we have been treating enteric fever with intravenous ceftriaxone empirically since 2007. in this study, we reevaluated our treatment protocol. this retrospective cohort study was conducted at a single institute in tokyo, japan, between january 2006 and december 2013. enteric fever was defined as isolation of salmonella typhi or salmonella paratyphi a, b, and c from the blood and/or sto ...201627162265
salmonella paratyphi b mycotic aneurysm of the abdominal aorta in an hiv-infected patient: a case report.an hiv-infected 49-year-old man was admitted with polyuria, fever, chills and a dull left lumbar pain. laboratory tests showed increased c-reactive protein while urine analysis and abdomen ultrasound scan were negative. blood cultures revealed a salmonella paratyphi b, identified through maldi-tof mass spectrometry. targeted antibiotic therapy with intravenous piperacillin/tazobactam was started and a multi-phase contrast-enhanced abdomen ct-scan was performed at 24 hours from admission showing ...201526110299
detection of tem-, shv- and ctx-m-type β-lactamase production among clinical isolates of salmonella species.enteric fever is a major public health problem in developing countries. due to the problem of resistance to first-line drugs and fluoroquinolone, cephalosporins are currently used for treatment of enteric fever. cephalosporin resistance in salmonella spp. is mainly due to production of extended-spectrum β-lactamases (esbls). the majority of esbls in salmonella are derivatives of the tem and shv β-lactamase families. the objectives of this study were to detect antibiotic susceptibility patterns, ...201424866367
the discrimination of d-tartrate positive and d-tartrate negative s. enterica subsp. enterica serovar paratyphi b isolated in malaysia by phenotypic and genotypic methods.serotyping is not sufficient to differentiate between salmonella species that cause paratyphoid fever from the strains that cause milder gastroenteritis as these organisms share the same serotype salmonella paratyphi b (s. paratyphi b). strains causing paratyphoid fever do not ferment d-tartrate and this key feature was used in this study to determine the prevalence of these strains among the collection of s. paratyphi b strains isolated from patients in malaysia. a total of 105 isolates of s. p ...201222870596
salmonella paratyphi b and salmonella litchfield outbreaks associated with pet turtle exposure in spain.salmonellosis is an important public health problem. turtles are increasingly involved in the role of transmitters of this infection to humans.201322795887
salmonella paratyphi b septicemia in a neonate.septicemia is a major cause of death in neonates especially in developing countries. we report a case of septicemia in a neonate due to salmonella paratyphi b. the baby responded well to therapy and recovered completely.201324049752
salmonella paratyphi b meningitis in an infant.we report a case of salmonella paratyphi b meningitis in a 90 day-old male infant who was admitted with complaints of fever, vomiting and one episode of vacant stare. clinically, the infant was found to be toxic and dull with a bulging anterior fontanelle. subsequently, blood and cerebrospinal fluid cultures demonstrated the presence of salmonella paratyphi b organism.201323940494
a case report of acute acalculous cholecystitis due to salmonella paratyphi b complicated by biliary peritonitis.non-typhoidal salmonella are a rare case of acute acalculouscholecystitis (aac). salmonella paratyphi b, which accounts for one of the less invasive nts serotypes, has rarely been reported to cause cholecystitis. we describe a case of 65-year old previously healthy man, who present with signs of acute abdomen, due to biliary peritonitis as a complication of acute acalculouscholecystitis caused by salmonella paratyphi b. our case illustrates the potential severity of infection with salmonella par ...201324839535
