A Turkish woman aged 44 years who presented with a 1 month history of abdominal pain, fatigue and weight loss of 10 kg was diagnosed as having acute tubulointerstitial nephritis. Opthalmological evaluation revealed unilateral uveitis and contralateral chorioretinal scarring. X-ray films of the pelvis revealed unilateral sacroileitis. An elevated erythrocyte sedimentation rate, C-reactive protein, tubular proteinuria and renal glucosuria returned to normal 2 weeks after treatment was started. It is important to be aware of tubulointerstitial nephritis and uveitis syndrome in order to achieve a quick diagnosis in patients with renal impairment and tubular dysfunction with minor symptoms so that appropriate management can be started early.
A total of 50 Salmonella enterica strains were isolated from clinical samples from 2009 to 2012 and analyzed for the presence of virulence genes found in SPI-1, SPI-2, and plasmids. The distribution and frequency of the antimicrobial resistance genes and plasmids were revealed, and pulsed-field gel electrophoresis (PFGE) patterns were investigated. Five genes were identified from the seven strains with resistance or intermediate resistance to ampicillin: blaSHV-1 (present in six strains), qnrS1 (present in five strains), blaTEM-1 (present in three strains), blaCTX-M-1 (present in one strain), and qnrB1 (present in one strain). One trimethoprim-sulfamethoxazole-resistant strain was positive for sulI but negative for sulII. In addition, we detected TEM-1 and qnrS1 in one strain; SHV-1 and qnrS1 in two strains; TEM-1, SHV-1, CTX-M-1, and qnrS1 in one strain; TEM-1, SHV-1, and qnrB1 in one strain; and SHV-1 and sulI genes in one strain together. Plasmid-based replicon typing assay revealed that all 50 strains carried FIIS, 13 carried I1, 1 carried I2, 4 carried P, 1 carried A/C, and 4 carried X1 replicon. PFGE was used to type 46 of the 50 strains and classify them into 22 major groups, 33 pulsotypes, and 8 major clusters. All strains carried all the virulence genes of interest on both Salmonella Pathogenicity Islands 1 and 2 and plasmids suggested high potential for pathogenicity. All antimicrobial-resistant strains contained at least one of the resistance genes of interest, confirming a phenotype-genotype association in antimicrobial resistance.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
