Rapid and visual detection of Shiga-toxigenic Escherichia coli (STEC) in carabeef meat harnessing loop-mediated isothermal amplification (LAMP).

Shiga toxigenic E. coli are important foodborne zoonotic pathogens. The present study was envisaged to standardize loop-mediated isothermal amplification assays targeting stx1 and stx2 genes for rapid and visual detection of STEC and compare its sensitivity with PCR.

Kisspeptin stimulates oestradiol biosynthesis by upregulating steroidogenic transcripts and proliferation markers in the bubaline granulosa cells in vitro.

Kisspeptin (Kp), an upstream regulator of GnRH release, is essential for the development and function of reproductive axis. Previously, we demonstrated the localization of Kp and its receptor (Kiss1r) in the active follicle in the bubaline ovary. Present study aimed to determine the effect of Kp on granulosa cell (GCs) functions, especially oestradiol (E ) and progesterone (P ) production, and differential expression of genes regulating the proliferation, apoptosis and steroidogenesis in the buffalo.

Serum concentrations of secretory leukocyte protease inhibitor and IL6 can predict the onset of sepsis in pyometra bitches.

As onset of sepsis adversely affects the prognosis of canine pyometra, finding biomarkers that would distinguish sepsis status would be useful in the clinical management. Accordingly, we hypothesized that differential expression of endometrial transcripts and circulating concentration of certain inflammatory mediators would discriminate pyometra-led sepsis (P-sepsis+) from those of pyometra without sepsis (P-sepsis-). Bitches with pyometra (n = 52) were classified into P-sepsis+ (n = 28) and P-sepsis- (n = 24) based on vital clinical score and total leukocyte count.

Analysis of bluetongue disease epizootics in sheep of Andhra Pradesh, India using spatial and temporal autocorrelation.

Bluetongue (BT) disease poses a constant risk to the livestock population around the world. A better understanding of the risk factors will enable a more accurate prediction of the place and time of high-risk events. Mapping the disease epizootics over a period in a particular geographic area will identify the spatial distribution of disease occurrence.

Responses to COVID-19 in South Asian Association for Regional Cooperation (SAARC) countries in 2020, a data analysis during a world of crises.

Coronavirus disease (COVID-19) caused by SARS-CoV-2 was notified from Wuhan city, Hubei province, China in the mid of December 2019. The disease is showing dynamic change in the pattern of confirmed cases and death toll in these low and middle-income countries (LMICs). In this study, exponential growth (EG) method was used to calculate the real-time reproductive number (R) for initial and later stage of epidemic in South Asian Association for Regional Cooperation (SAARC) member countries (April 2020 - December 2020).

Molecular characterization of porcine rotavirus A from India revealing zooanthroponotic transmission.

Rotaviruses A (RVA) are leading causes of diarrhea and dehydration in piglets and imply great economic loss to the pig farming community. In this study, the porcine RVA genotypes circulating in western and northern parts of India were determined by screening 214 fecal samples from diarrheic ( = 144) and non-diarrheic ( = 70) pigs. Subsequently, the structural (VP4 and VP7) and nonstructural (NSP3, and NSP4) genes were amplified, sequenced, and genetically characterized.

Seasonal pattern in occurrence of rotavirus infection (RV) in diarrheic children, calves and piglets from Bareilly, India.

Rapid and reliable diagnosis for diarrhoeal disease is critically important for the differentiation of etiological agents and subsequent suitable treatment modalities. The objective of the study is to reveal the seasonal pattern in the occurrence of rotavirus in diarrheic children, calves and piglets from Bareilly, Uttar Pradesh, India. A total of 115 diarrhoeal samples were collected, out of which 51 were collected during post-monsoon/autumn (September 2018-November 2018) and 64 during the winter season (December 2018-February 2019).

Japanese encephalitis virus-induced neuropathology in mouse model infected through the conjunctival route.

Background & Objectives: Mouse is a preferred animal model for studying pathogenesis of Japanese encephalitis virus (JEV) infections, and different routes of inoculation have been tried. Some neurotropic viruses can reach the brain following infection through ocular route. This study was undertaken to establish JEV-induced clinical disease in mouse model through conjunctival route and document the neuropathological effects.

Virulent methicillin resistant (MRSA) in street vended foods.

Street foods are one of the important sources of foodborne infections and is an important infectious agent transmitted through various sources including street foods. The methicillin-resistant (MRSA) are of public health significance, hence the study was taken to assess the street foods as a source of MRSA, for which 430 street vended foods of animal origin (meat, milk, eggs and their products) and associated environmental samples were processed for isolation and characterization. A total of 52 (12.

Antimicrobial resistance and typing of isolated from street vended foods and associated environment.

The present study was carried out to find out the occurrence and types of present in street vended foods and associated environment, and their resistance pattern against various antibiotics. About 1075 street vended food and associated environment samples were processed for isolation and confirmation of different spp. by targeting gene specific A gene and serotype specific I, and genes by PCR.

Human brucellosis among pyrexia of unknown origin cases and occupationally exposed individuals in Goa Region, India.

Background: Brucellosis is a widespread zoonotic infection. This disease is endemic in many parts of Asia, including India. Brucellosis is a major cause of pyrexia of unknown origin (PUO).

Evaluation of recombinant outer membrane protein based vaccine against Salmonella Typhimurium in birds.

Food-borne diseases caused by Salmonella enterica from poultry sources represent an important public health problem and no reliable control by vaccination has proved effective despite research. The aim of the present study was to evaluate the use of recombinant OmpC protein for immunization of birds to elucidate its protection against virulent Salmonella Typhimurium. The recombinant OmpC protein was prepared after cloning and expressing ompC gene and was characterized by SDS-PAGE and Western blot analyses.

Prevalence and genotypic (G and P) determination of porcine group A rotaviruses from different regions of India.

Group A rotaviruses can infect both humans and animals and have been recognized as an important cause of diarrhea in porcine. In this study, we report the prevalence and molecular epidemiology of rotaviruses detected in piglets in different regions of India. A total 275 fecal samples (180 diarrheal and 95 non-diarrheal) from piglets were collected from the western (135), southern (60), northern (20), and North-Eastern Hill (NEH) (60) regions of India and tested for rotaviruses.
