and gene polymorphism-a possible association with drug-resistant tuberculosis in the north Indian population.

Objectives: The objective of this study is to analyze the association between and gene polymorphism with drug resistant tuberculosis (PTB, MDR-TB, and XDR-TB) in a population from Agra, Uttar Pradesh.

Methods: The present case-control study included 101 pulmonary TB patients, 104 multidrug-resistant TB patients, 48 extremely drug-resistant TB patients, and 130 healthy and unrelated controls residing in the same locality. The genotyping method for was carried out by allele-specific polymerase chain reaction (PCR), and gene polymorphism was performed by hybridization probe chemistry in Roche Real-Time PCR.

Identification and differential expression of serotransferrin and apolipoprotein A-I in the plasma of HIV-1 patients treated with first-line antiretroviral therapy.

Background: Plasma proteins are known to interfere the drug metabolism during therapy. As limited information is available regarding the role of plasma proteins in HIV drug resistance during ART in HIV/AIDS patients, the present study aimed to identify and characterize the differentially expressed plasma proteins in the drug resistant and drug respondent groups of HIV-1 infected patients with > 6 years of first line ART.

Methods: Four-drug resistant (treatment failure) and four-drug respondent (treatment responder) patients were selected for plasma proteomic analysis based on viral load and drug resistance associated mutations from a cohort study designed on the first line ART patients who were enrolled in the antiretroviral therapy center, Sarojini Naidu Medical College, Agra, India from December 2009 to November 2016.

Development, standardization and validation of molecular techniques for malaria vector species identification, trophic preferences, and detection of .

Background & Objectives: Knowledge on prevalence of malaria vector species of a certain area provides important information for implementation of appropriate control strategies. The present study describes a rapid method for screening of major Anopheline vector species and at the same time detection of Plasmodium falciparum sporozoite infection and blood meal preferences/trophic preferences.

Methods: The study was carried from February 2012 to March 2013 in three seasons, i.

Multiplex PCR for rapid detection of serotype A foot-and-mouth disease virus variants with amino acid deletion at position 59 of the capsid protein VP3.

In India, there has been co-circulation, extinction and emergence of genotypes/lineages within serotype A foot-and-mouth disease (FMD) virus. At present an antigenically heterogeneous, unique lineage within genotype VII dominates the field outbreaks. This genetic cluster has amino acid deletion at position 59 of VP3 (VP3(59)-deletion group), considered to be critical antigenically.

Comparative analysis of the large fragment of the 5' untranslated region (LF-5' UTR) of serotype A foot-and-mouth disease virus field isolates from India.

India is endemic for foot-and-mouth disease (FMD) and in recent years a unique group within serotype A, carrying a codon deletion at an antigenically critical site in capsid protein VP3 has emerged (VP3(59)-deletion group). This tempted us to analyze the noncoding region, which is an under represented area, though critically associated with virus biology and pathogenesis. Analysis of the large fragment of 5' untranslated region (LF-5' UTR) of type A FMD virus revealed discrepancy in the overall tree topology between LF-5' UTR and 1D region possibly due to independent evolution of coding and noncoding regions.
