In vitro evaluation of adherence and anti-infective property of probiotic Lactobacillus plantarum DM 69 against Salmonella enterica.

Gastrointestinal infections are a global health problem, and the potential use of probiotic Lactobacillus species to control such infections represents a promising approach. To exert the health benefits on the host, studying the colonization and adherence properties of probiotic bacteria in vitro is crucial. In this context, investigation was carried out to evaluate adhesion, aggregation and anti-infective effect of an indigenous probiotic Lactobacillus plantarum DM 69 against an enteric pathogen Salmonella enterica subsp.

Co-circulation of all four dengue virus serotypes: First report from Odisha.

The present report describes the detection of co-circulation of all the four dengue serotypes along with rarely detected dengue viruses (DENVs)-4 for the first time in Odisha. One hundred and forty-eight blood samples were tested for dengue NS1 antigen ELISA and IgM antibody (Ab), and twenty early samples were subjected for type-specific multiplex reverse transcription-polymerase chain reaction (RT-PCR). Twenty-three samples found positive for dengue NS1 and/or IgM Ab; five were positive by RT-PCR.

Revisiting the global problem of cryptosporidiosis and recommendations.

Cryptosporidiosis is a gastrointestinal illness caused by the protozoan parasite species, which is a leading cause of diarrhea in a variety of vertebrate hosts. The primary mode of transmission is through oral routes; infections spread with the ingestion of oocysts by susceptible animals or humans. In humans, infections are commonly found in children and immunocompromised individuals.

In silico identification and validation of a novel hypothetical protein in Cryptosporidium hominis and virtual screening of inhibitors as therapeutics.

Computational approaches to predict structure/function and other biological characteristics of proteins are becoming more common in comparison to the traditional methods in drug discovery. Cryptosporidiosis is a major zoonotic diarrheal disease particularly in children, which is caused primarily by Cryptosporidium hominis and Cryptosporidium parvum. Currently, there are no vaccines for cryptosporidiosis and recommended drugs are ineffective.

Etiology, seasonality, and clinical characteristics of respiratory viruses in children with respiratory tract infections in Eastern India (Bhubaneswar, Odisha).

Acute respiratory tract infections (ARTIs) are a leading cause of morbidity and mortality in young children in low and middle income countries. To analyse the overall burden of respiratory viruses responsible for ARTIs in paediatrics population in eastern India, this study was performed. Clinical information, demographic information and nasal/oral swabs were collected from 332 paediatric patients (aged from 1 month to 12 years old) with the symptoms of ARTI, enrolled from the outpatient department from Nov 2012 to Oct 2014.

Comparison of bluetongue virus detection and quantitation methods in south India.

Introduction: Bluetongue (BT), a vector-borne viral disease, primarily affects sheep. Of the 26 serotypes of BTV identified so far, 22 are reported to be circulating in India. Due to an increase in vector population and delays in disease diagnosis, the BT control program heavily relies on rapid and confirmatory diagnosis.

Human metapneumovirus: review of an important respiratory pathogen.

Human metapneumovirus (hMPV), discovered in 2001, most commonly causes upper and lower respiratory tract infections in young children, but is also a concern for elderly subjects and immune-compromised patients. hMPV is the major etiological agent responsible for about 5% to 10% of hospitalizations of children suffering from acute respiratory tract infections. hMPV infection can cause severe bronchiolitis and pneumonia in children, and its symptoms are indistinguishable from those caused by human respiratory syncytial virus.

Hepatitis E virus: the current scenario.

Hepatitis E infection, caused by the hepatitis E virus (HEV), is a common cause of acute hepatitis in developing countries with poor sanitation and hygiene. The virus is classified into four genotypes (1-4) with one serotype. Genotypes 1 and 2 exclusively infect humans, whereas genotypes 3 and 4 also infect other animals, particularly pigs.

Molecular detection and sequence analysis of hepatitis E virus in patients with viral hepatitis from North India.

Viral hepatitis is a major cause of mortality and morbidity in developing countries. Hepatitis E virus (HEV) is responsible for both sporadic and epidemic outbreaks of viral hepatitis in India. Here a total of 843 samples were collected: 685 from patients with acute viral hepatitis (AVH), 70 from patients with fulminant hepatic failure (FHF), 53 from patients with chronic liver disease (CLD), 11 from patients with antituberculosis therapy (ATT)-induced jaundice, and 24 from pregnant women.
