Unlabelled: , a zoonotic pathogen causing enteric diseases in different animals and humans. A comprehensive study on the presence of toxin genes and antimicrobial resistance genes based on genome data of in animals is scanty. In the present study, a total of 15 isolates were recovered from dogs and isolates with toxin genes (D1, CD15 and CD26) along with two other non-toxigenic strains (CD28, CD32) were used for whole genome sequencing and comparative genomics.

Article Synopsis
  • * Researchers isolated and sequenced genomes from 9 animal samples (4 cattle, 4 deer, and 1 buffalo) that died from tuberculosis and compared them to existing data, revealing a closed pangenome structure and a unique SNP in a virulence gene as a potential identification marker.
  • * The findings indicate that this specific MTBC member is prevalent in South Asian animals, highlighting its zoonotic potential and the need for further evaluation of its impact on animal and human health.

Several Pasteurella like organisms isolated from various avian species were recently reclassified into new genus based on whole genome sequence analysis. One such Pasteurella like organism, Bisgaard taxon 14 was classified as Spirabiliibacterium mucosae. In the present study, a Gram-negative organism was isolated from ailing pigeons with respiratory infection from a farm in Tamil Nadu, India and the organism was misidentified as Burkholderia mallei by Vitek 2 compact system based on biochemical characterization.

Brucellosis poses a significant burden to human and animal health worldwide. Robust and harmonized molecular epidemiological approaches and population studies that include routine disease screening are needed to efficiently track the origin and spread of Brucella strains. Core genome multilocus sequence typing (cgMLST) is a powerful genotyping system commonly used to delineate pathogen transmission routes for disease surveillance and control.

Trained immunity is a renewed concept of innate immune memory that facilitates the innate immune system to have the capacity to remember and train cells via metabolic and transcriptional events to enable them to provide nonspecific defense against the subsequent encounters with a range of pathogens and acquire a quicker and more robust immune response, but different from the adaptive immune memory. Reversing the epigenetic changes or targeting the immunological pathways may be considered potential therapeutic approaches to counteract the hyper-responsive or hypo-responsive state of trained immunity. The efficient regulation of immune homeostasis and promotion or inhibition of immune responses is required for a balanced response.

Article Synopsis
  • The study focuses on a dangerous Gram-positive bacterium responsible for gas gangrene, which is often fatal in both humans and animals.
  • Researchers sequenced and analyzed the complete genome of a specific strain alongside five others to understand genetic diversity and structures better.
  • Findings revealed a stable genetic group with variations in accessory genes and a range of potential virulence factors, highlighting insights into the pathogen's relatedness and virulence mechanisms.

causes small ruminant brucellosis and a zoonotic pathogen prevalent worldwide. Whole genome phylogeny of all available genomes ( = 355) revealed that all Indian isolates ( = 16) clustered in the East Mediterranean lineage except the ADMAS-GI strain. Pangenome analysis indicated the presence of limited accessory genomes with few clades showing specific gene presence/absence pattern.

Avian chlamydiosis is one of the important neglected diseases with critical zoonotic potential. Chlamydia psittaci, the causative agent, affects most categories of birds, livestock, companion animals, and humans. It has many obscured characters and epidemiological dimensions, which makes it unique among other bacterial agents.

Interaction of SARS-CoV-2 spike glycoprotein with the ACE2 cell receptor is very crucial for virus attachment to human cells. Selected mutations in SARS-CoV-2 S-protein are reported to strengthen its binding affinity to mammalian ACE2. The N501T mutation in SARS-CoV-2-CTD furnishes better support to hotspot 353 in comparison with SARS-CoV and shows higher affinity for receptor binding.
