Genetic evaluation of growth and reproductive performances of crossbred pigs reared under intensive system in tropical humid coastal climate.

Pig farming is one of the most economically viable options for the rural backward and resource-poor farmers in Asian countries. Growth rate and litter size are the most important traits based on which the crossbreeding programs are typically planned in commercial pig farming. The modern system of farming with high yielding improved pig germplasm helps in economic growth in piggery enterprises.

Luteolin-Fabricated ZnO Nanostructures Showed PLK-1 Mediated Anti-Breast Cancer Activity.

The present work describes a facile and convenient procedure for synthesizing zinc oxide nanoparticles using luteolin isolated from plant (L-ZnONPs) at room temperature. The formation of as-grown L-ZnONPs was confirmed by X-ray diffraction analysis (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), high-resolution transmission electron microscopy (HR-TEM), and selected area electron diffraction (SAED). The Wurtzite structure of ZnO was observed by its hexagonal phases in diffraction patterns.

Reviewing the ecological evidence base for management of emerging tropical zoonoses: Kyasanur Forest Disease in India as a case study.

Zoonoses disproportionately affect tropical communities and are associated with human modification and use of ecosystems. Effective management is hampered by poor ecological understanding of disease transmission and often focuses on human vaccination or treatment. Better ecological understanding of multi-vector and multi-host transmission, social and environmental factors altering human exposure, might enable a broader suite of management options.

Seroprevalence of in cattle and analysis of associated climatic risk factors in Mizoram, India.

Surra, a haemoprotozoan parasitic disease even in subclinical form poses a challenge in terms of diagnosis and management to animal health practitioners and policy makers as well; eventually imparting financial loss to the livestock holders. A systematic study was designed to assess the seroprevalence of surra in cattle and associated climatic risk factors, by collecting 480 serum samples across the eight districts of Mizoram during 2017-2019. The apparent and true seroprevalence detected by card agglutination test was 37.

Foot and Mouth Disease (FMD) incidence in cattle and buffaloes and its associated farm-level economic costs in endemic India.

The study investigated the important epidemiological parameters and farm-level economic costs of FMD incidence in cattle and buffaloes during 2013-14 to 2015-16 in various states of India. Multistage random sampling procedure was adopted for the primary survey and data was collected through face-to-face personal interview from 18,609 cattle and buffalo rearing farm households from 123 districts across twelve states and one Union Territory. Besides epidemiological parameters, different farm-level direct and indirect loss associated with FMD was assessed at disaggregated level (states) by employing deterministic mathematical models.

'None of my ancestors ever discussed this disease before!' How disease information shapes adaptive capacity of marginalised rural populations in India.

Smallholder farmer and tribal communities are often characterised as marginalised and highly vulnerable to emerging zoonotic diseases due to their relatively poor access to healthcare, worse-off health outcomes, proximity to sources of disease risks, and their social and livelihood organisation. Yet, access to relevant and timely disease information that could strengthen their adaptive capacity remain challenging and poorly characterised in the empirical literature. This paper addresses this gap by exploring the role of disease information in shaping the adaptive capacity of smallholder farmer and tribal groups to Kyasanur Forest Disease (KFD), a tick-borne viral haemorrhagic fever.

Evaluation of the diagnostic potential of recombinant leptospiral OMP A-like protein (Loa22) and transmembrane (OmpL37) protein in latex agglutination test for serodiagnosis of leptospirosis in animals.

Leptospirosis is a re-emerging zoonotic disease of animals and humans caused by pathogenic Leptospira, which has major public health concerns. The study is aimed to express the recombinant outer membrane protein (OMP) A-like protein (rLoa22) and transmembrane (rOmpL37) protein of Leptospira interrogans serovar Hardjo in the Escherichia coli and their evaluation as a diagnostic antigen in the latex agglutination test (LAT) to detect anti-leptospiral antibodies in the sera of animals. The Loa22 and OmpL37 genes lacking signal peptide coding sequences were individually amplified (522 and 963 bp), by polymerase chain reaction, and directionally cloned into a pETite N-His Kan vector for expression.

Bluetongue is an insect borne (Culicoides) viral disease of small ruminants. The virus blankets the globe with a wide serotypic variation, numbered from 1 to 28. In India 21 different serotypes have been reported to be circulating across the various agro-climatic zones of the country.

Evaluation of recombinant BgSA3 protein based indirect-ELISA for sero-diagnosis and sero-surveillance of Babesia gibsoni in dogs.

Canine babesiosis, a tick-borne haemoprotozoan disease of dogs, is of significance globally due to its rapid spread. A precise confirmatory diagnosis is required to curtail the rapid spread of infection. Our study described the evaluation of recombinant BgSA3 protein based indirect ELISA for sero-diagnosis and sero-surveillance of Babesia gibsoni infection in dogs.

Monoclonal antibodies against foot-and-mouth disease virus RNA polymerase for detection of virus infection.

Foot-and-mouth disease (FMD) is a major viral disease in farm animals. In the present study, seven monoclonal antibodies (mAbs) were produced against the FMD virus (FMDV)-encoded RNA-dependent RNA polymerase (3D protein) and characterized. Screening of mAb reactivity against three overlapping fragments of the 3D protein expressed in Escherichia coli revealed that the binding sites of all the mAbs were confined to the N-terminal one-third of the 3D protein.

Detection of coinfection of a divergent subgroup of genotype I Japanese encephalitis virus in multiple classical swine fever virus outbreaks in pigs of Assam, India.

A retrospective investigation of pig tissue samples from different classical swine fever virus (CSFV) outbreaks was undertaken employing RT-PCR for possible coinfection with other swine viruses. Four samples from three different outbreaks were found to be coinfected with Japanese encephalitis virus (JEV). Phylogenetic analysis was done based on complete E gene sequenced from all four coinfected samples.

Variability in biofilm production and antimicrobial sensitivity pattern among strains.

Biofilm production, hitherto an uncharacterized feature among circulating strains, was studied along with the antibiotic susceptibility pattern. On the basis of biofilm formation ability, all the strains were categorized into four groups under six different culture conditions: strong biofilm-forming (22%), moderate (19%), weak (51%), and non-adherent (7%). Strains from serogroups A and B formed significant biofilms in at least one culture condition whereas strains from serogroup D were unable to form biofilms.

Comparative genetic diversity analysis based on virulence and repetitive genes profiling of circulating Pasteurella multocida isolates from animal hosts.

Virulence associated and/or housekeeping/repetitive genes either in single or multiple copies are being extensively targeted for bacterial pathogen detection and differentiation in epidemiological studies. In the present study, isolation of Pasteurella multocida from different animals and their genetic profiling based on the capsular types, virulence and repetitive elements (ERIC/REP) were carried out. A total 345 clinical samples from apparently healthy and diseased (pneumonic, septicaemia) animals (sheep, goat, pig, cattle, buffalo and rabbits) from different geographical regions of Karnataka, Uttar Pradesh, Mizoram and Assam states of India were screened.

Risk factors for spp. and infection among small ruminants in Eastern India.

Small ruminants are the main reservoirs for brucellosis and coxiellosis, two zoonotic diseases affecting livestock production, and posing a public health threat in India. Understanding disease prevalence and risk factors associated with small ruminant infection can help mitigate disease transmission. We report a cross-sectional survey in the states of Assam and Odisha in Eastern India.

Evaluation of the immune responses against reduced doses of Brucella abortus S19 (calfhood) vaccine in water buffaloes (Bubalus bubalis), India.

Background: Brucella abortus S19 is the most widely used vaccine for the prevention of bovine brucellosis which remains the reference vaccine to which many other vaccine/s are compared. Considering the larger vaccination coverage by reduced dose of vaccine, the study aimed to compare reduced graded doses (1/10th, 1/20th and 1/100th) with standard dose of S19 vaccine (40 × 10CFU /dose) to determine the effective immunizing dose in water buffaloes.

Methods: A total of 25 female buffalo calves (Bubalus bubalis) in the age group of 4-5 months were equally grouped into five animals each in four test and one control groups and given with specified vaccine dose.

In silico Functional Annotation and Characterization of Hypothetical Proteins from FGI94.

, rod-shaped Gram-negative bacteria is classified as an opportunistic pathogen in the family Enterobacteriaceae. It causes a wide variety of infections in humans, including urinary, respiratory, ocular lens and ear infections, osteomyelitis, endocarditis, meningitis and septicemia. Unfortunately, over the past decade, antibiotic resistance has become a serious health care issue; the effective means to control and dissemination of resistance is the need of hour.

Molecular phylogeny of Capripoxviruses based on major immunodominant protein (P32) reveals circulation of host specific sheeppox and goatpox viruses in small ruminants of India.

Sheeppox and goatpox are highly contagious viral diseases of small ruminants causing severe economic losses to the livestock farmers. The disease is enzootic in Asia including India, Middle East and African countries. In the present study, a total of 28 isolates from twenty five sheeppox and goatpox disease outbreaks were phylogenetically analyzed based on P32 gene/protein along with homology modeling and docking using heparan sulfate and UDP-glucose.

Bovine babesiosis: An insight into the global perspective on the disease distribution by systematic review and meta-analysis.

Bovine babesiosis is continuing as a great threat to the livestock sector causing havoc production losses with significant morbidity and mortality. Being a tick-borne disease, the great complexity in the agent-host- vector relationship has severely hampered the sincere efforts towards the development of an effective vaccine against bovine babesiosis. In these circumstances, assessing the global scenario of disease prevalence is a prerequisite to strategize the available control measures.

Predicting disease risk areas through co-production of spatial models: The example of Kyasanur Forest Disease in India's forest landscapes.

Zoonotic diseases affect resource-poor tropical communities disproportionately, and are linked to human use and modification of ecosystems. Disentangling the socio-ecological mechanisms by which ecosystem change precipitates impacts of pathogens is critical for predicting disease risk and designing effective intervention strategies. Despite the global "One Health" initiative, predictive models for tropical zoonotic diseases often focus on narrow ranges of risk factors and are rarely scaled to intervention programs and ecosystem use.

Pulmonary inflammatory response to influenza virus infection in pigs is regulated by DAP12 and macrophage M1 and M2 phenotypes.

We delineated the expression of DAP12 (DNAX-Activating Protein) and its associated receptors, TREM-1, TREM-2 and MDL-1 in pig alveolar monocyte/macrophages (AMM) that have attained M1 or M2 phenotypes. Pig AMM stimulated in vitro with IFN-γ and IL-4 induced the expression of M1 (TNFα and iNOS) and M2 (ARG1 and no MMR) phenotypic markers, respectively. In influenza virus infected pigs at seven days post-infection, in addition to substantial modulations in the M1 and M2 markers expression, DAP12, TREM-1 and MDL-1 were downregulated in AMM.
