Sequencing of the genomes of Mycobacterium tuberculosis and Mycobacterium bovis provides a unique opportunity to study the biology of these pathogens on the genomic level. The computational detection of anomalous gene clusters such as those encompassed by pathogenicity islands allows for a narrowing of the study into well-defined groups of genes. Pathogenicity islands of M. tuberculosis (strains H37Rv and CDC1551) as well as M. bovis genomes comprise a group of genes encoding proteins that have been shown to be of immunological importance. The cross-genomic comparison (M. tuberculosis vs M. bovis) resulted in the elucidation of unique proteins in M. tuberculosis. These proteins may play a significant role in the host recognition process.

Bats are reservoir hosts for numerous well-known zoonotic viruses, but their broader virus-hosting capacities remain understudied. are an order of enteric viruses known to cause disease across a wide range of mammalian hosts, including Hepatitis A in humans and foot-and-mouth disease in ungulates. Host-switching and recombination drive the diversification of worldwide.

Background: Gene methylation in cells is an important factor in tumorigenesis, and radiotherapy can change DNA methylation in cells. In this study, complete genome methylation sequencing (BS-Seq) technology was used to analyze the genome-wide methylation of patients with cervical cancer before and after radiotherapy.
Methods: Three pairs of cervical squamous cell carcinoma samples were collected from patients before and after radiotherapy in July 2020.

DNA methylation (DNAm) regulates gene expression and genomic imprinting. This study aimed to investigate the effect of gastrointestinal (GI) nematode infection on host DNAm. Helminth-free Holstein steers were either infected with (the brown stomach worm) or given tap water only as a control.

Analyzing genetic variability and inbreeding trends is essential for effective breed management in animal populations. To this, the characterization of runs of homozygosity (ROH) provides a good genomic approach to study the phenomena. The Polo Argentino (PA) breed, globally recognized as the best adapted to playing polo, is known for its strong influence of Thoroughbreds, intense selective breeding, and extensive use of reproductive biotechnologies.
