Prevalence of ESBL in Isolates Among ICU Patients in a Tertiary Care Hospital.

Introduction: Resistance to common antibiotics is a matter of grave concern in treating infections in hospital settings especially in Intensive Care Units (ICUs). One of the most commonly used and effective group of antibiotics, cephalosporins, exhibit resistance due to production of Extended Spectrum Beta- Lactamases (ESBLs). The prevalence of ESBL producing () has increased throughout the world and is a major cause of treatment failure in ICUs.

Genomic characterization of Nipah virus, West Bengal, India.

An intrafamilial outbreak in West Bengal, India, involving 5 deaths and person-to-person transmission was attributed to Nipah virus. Full-genome sequence of Nipah virus (18,252 nt) amplified from lung tissue showed 99.2% nt and 99.

Estimation of the predictive role of plasma viral load on CD4 decline in HIV-1 subtype C-infected subjects in India.

Background: Plasma viral load has been shown to be a meaningful prognostic marker for disease progression in untreated, HIV-1 subtype B-infected subjects in United States and Western Europe and therefore used as a prognostic marker for disease progression. Because of high expenses of commercially available viral load assays, the role of viral load in disease progression has not been evaluated in HIV-1 subtype C-infected patients in India.

Methods: We developed an inexpensive real-time reverse transcriptase-polymerase chain reaction assay to quantify viral load in plasma of HIV-1 subtype C-infected subjects from India and used it in a longitudinal analysis of viral load and CD4 cell number in HIV-infected subjects from Calcutta, India.

Disordered structure and function of liver in HIV/AIDS--a study of thirty cases.

To study abnormalities in liver associated enzymes and histology in AIDS patients with common infections like hepatotrophic viruses and mycobacteria. 30 cases of HIV/AIDS were studied for any significant pattern emerging. The male:female ratio was 4.

No association between seropositivity for hepatitis C virus and lichen planus: a case control study.

Background: The epidemiological association of lichen planus (LP) with hepatitis C virus (HCV) infection has been recorded from some countries and HCV RNA3 has been isolated from lesional skin in patients with LP and chronic HCV infection. The observed geographical differences regarding HCV infection and LP could be immuno-genetically related.

Aim: To determine whether HCV has a causal relationship with LP.

Construction and characterization of an infectious molecular clone of HIV-1 subtype A of Indian origin.

India has the second highest number of HIV-1 infected people next to South Africa. The predominant proportion of HIV-1 circulating in India is of subtype C origin, with a small fraction made up of subtypes A and B. In this report, we describe the construction and characterization of the first full-length infectious molecular clone p1579A-1 HIV-1, from an HIV-1 subtype A infected person from India, using long PCR and successive ligation of the amplimers.

First report in India of HIV transmission through artificial insemination.

A case of HIV-1 transmission through artificial inseminations from infertility clinics in Kolkata, is reported.

High incidence and prevalence of HIV-1 infection in high risk population in Calcutta, India.

HIV-1 infection in India has been increasing steadily over the last decade. In the absence of potent antiviral therapy, estimates of HIV infection are needed to monitor the epidemic, institute prevention strategies in target populations and determine the suitable populations for vaccine studies. In this report we present the HIV-1 seroprevalence and annual estimates of seroincidence in a high risk population from Calcutta, the most populous city in the eastern part of India.
