Molecular characterization of O1 strains circulating in Assam: a north eastern state of India.

Background And Objectives: Information on the genetic epidemiology of cholera in Assam, a northeastern state of India is lacking despite cholera being a major public health problem. The study aimed to determine the virulence genes and genes encoding antibiotic resistance in isolates and to determine the prevalent genotypes based on the presence or absence of the virulence genes and genotype.

Materials And Methods: Twenty-five strains were subjected to conventional biotyping and serotyping followed by multiplex PCR to detect and and antibiotic resistance genes.

Prevalence of O1 serogroup in Assam, India: A hospital-based study.

Background & Objectives: Although cholera remains to be an important public health problem, studies on reliable population-based estimates of laboratory confirmed cholera in endemic areas are limited worldwide. The aim of this hospital-based study was to evaluate the prevalence of Vibrio cholerae serogroup in Assam, India, during 2003-2013.

Methods: Stool samples/rectal swabs were collected from acute watery diarrhoea (AWD) cases during 2003-2013 and processed by standard microbiological procedures.

Clinico-epidemiological study of tinea incognito with microbiological correlation.

Background: Tinea incognito is a dermatophytic infection with a clinical presentation that is modified due to previous treatment with topical or systemic steroids, as well as topical immunomodulators. It tends to mimic other dermatological conditions.

Aims: To evaluate the various clinical manifestations, sites, predisposing factors and causative agents of tinea incognito.

A serological study of cytomegalovirus infection in pregnant and non-pregnant women at Gauhati Medical College and Hospital.

Primary cytomegalovirus infection is the most common infection during pregnancy that may have long-term neurodevelopmental sequelae in children born to these mothers. It is also associated with many obstetric complications. So the aim of this study was to determine the seroprevalence of cytomegalovirus infection in local antenatal population with bad obstetric history and to see the effects, if any, of age, socio-economic status, presenting features and different gestational periods.

Chromoblastomycosis.

A case of a 45 years male patient with irregular warty growths over the right leg of 35 years duration is reported. The diagnosis was confirmed mycologically and histopathologically. Isolate was identified as Fonsecaea pedrosoi.
