Brain abscess caused by Cladophialophora bantiana is a rare disease associated with high mortality due to delay in diagnosis and absence of standardized therapy. We reviewed 124 culture proven C. bantiana brain abscess cases; 103 cases published in English literature during 1952 through 2014 and 21 unpublished cases from our reference center. The majority(More)
BACKGROUND Prompt and accurate diagnosis of extra-pulmonary tuberculosis (TB) is highly challenging. Current conventional techniques lack sensitivity and are time-consuming. Here, we report our experience with multiplex polymerase chain reaction (MPCR) using two targets namely IS6110 and protein antigen b in the diagnosis of extra-pulmonary TB. MATERIALS(More)
In recent years, the well-known plant pathogens of the Colletotrichum genus were increasingly reported to cause ophthalmic infections in humans. Among 66 species in the Colletotrichum genus, only a few are known to be pathogenic for humans. We report here five cases of ophthalmic infections due to Colletotrichum truncatum, a species never reported earlier(More)
The epidemiology of enteropathogenic Escherichia coli (EPEC) and the significance of isolation of atypical EPEC (aEPEC) in childhood diarrhoea have not been well studied in an Indian context. A comparative study was undertaken to investigate virulence determinants, antibiotic susceptibility patterns and serogrouping of typical EPEC (tEPEC) versus aEPEC(More)
Crimean Congo hemorrhagic fever (CCHF) is one of the deadly hemorrhagic fevers that are endemic in Africa, Asia, Eastern Europe, and the Middle East. It is a tick-borne zoonotic viral disease caused by CCHF virus of genus Nairovirus (family Bunyaviridae). CCHF not only forms an important public health threat but has a significant effect on the healthcare(More)
BACKGROUND Hemophagocytic syndrome (HPS) is a rare clinicopathological condition characterized by the activation of macrophages with prominent hemophagocytosis in bone marrow and other reticulo-endothelial systems. HPS can be familial or secondary to infections including viruses. AIM To study the viral markers in patients with HPS. MATERIALS AND METHODS(More)
This study has evaluated the clinical applicability of a single-tube multiplex RT-PCR as compared with a two-step nested RT-PCR for the diagnosis as well as serotyping of dengue virus in patient's samples. Seventy-six acute phase blood samples collected from clinically suspected dengue patients during the 2008 outbreak were subjected to two-step nested(More)
Shigellemia is a complication of shigellosis that occurs generally in malnourished children. In adults, shigellemia is usually seen in immunocompromised individuals. Here we report the first case of shigellemia in a renal transplant patient from India. The patient had history of diarrhea, which was treated symptomatically. Subsequently, the patient(More)
Resistance to third-generation cephalosporins in non-typhoidal Salmonella (NTS) is emerging worldwide. We report the occurrence of extended-spectrum beta-lactamase (ESBL) phenotypes in 53.4 % of NTS isolated over a period of nine years from gastroenteritis cases. ESBL and AmpC co-production was observed in 21 % of the isolates. Occurrence of blaCTX-M-15 and(More)
Humans are known to serve as the secondary intermediate host for some larval forms of canine or feline tapeworms. Sparganosis is caused by plerocercoid larva of Spirometra of which there are three main species; Spirometra mansoni (or Spirometra erinaceieuropaei), Spirometra mansonoides and Spirometra proliferum. A one-and-half-year-old patient presenting(More)
