Infection with Lactobacillus is rare, and only a handful of species have been identified as being clinically significant: Lactobacillus casei, Lactobacillus rhamnosus, and Lactobacillus leichmannii. The literature contains one case report of bacteremia caused by Weissella confusa (basonym: Lactobacillus confusus), but the clinical significance of the infection was unclear. We describe a case of W. confusa bacteremia in a 46-year-old man with a history of abdominal aortic dissection and repair. This procedure was complicated by gut ischemia, which necessitated massive small bowel resection. He subsequently developed short-bowel syndrome, which required him to have total parenteral nutrition. He later developed an Enterococcus faecalis aortic valve endocarditis that required a coronary artery bypass graft and aortic root replacement with homograft and 6 weeks of intravenous ampicillin and gentamicin. Three months prior to his most recent admission, he was diagnosed with Klebsiella pneumoniae bacteremia and candidemia. At the present admission, he had fever (T max , 39.5°C) and chills of 2 days' duration and was admitted to the intensive care unit because of hemodynamic instability. Blood cultures grew K. pneumoniae and W. confusa in four of four blood culture bottles (both aerobe and anaerobe bottles).
Imaging studies failed to find any foci of infection. A transesophageal echocardiogram revealed no vegetations
The aim of this study was to evaluate the general characteristics of commercially available enzyme-linked immunosorbent assays (ELISAs) to detect antibody against classical swine fever (CSF), as well as to assess their potential use as accompanying marker tests able to differentiate infected from vaccinated animals (DIVA). The Chekit * CSF-Sero and the HerdChek * CSFV Ab, both of which detect antibodies against the E2 protein of classical swine fever virus (CSFV), had the highest sensitivity. Both tests were practicable and showed good reproducibility. Comparable sensitivity was shown by the Chekit * CSF-Marker, an E rns ELISA. However, this test does not allow differentiation between antibodies directed against ruminant pestiviruses and those against CSFV. Therefore, it is not suitable for use with the chimeric marker vaccines tested. The PrioCHECK ® CSFV E rns was the only ELISA suitable for use in DIVA with marker vaccines containing E rns proteins from ruminant pestiviruses. However, this test was less sensitive and selective than the E2-ELISAs and cannot be recommended.
Otitis externa and otitis media are commonly encountered in clinical practice. We report an unusual case of otitis externa, which was caused by Vibrio alginolyticus, several months after saltwater exposure. Clinicians need to be aware of this unusual pathogen, especially in refractory cases of ear infections.
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.
