This study evaluated the possibility to use six phages specific to the Mycobacterium tuberculosis lipoarabinomannan (LAM) as tools for tubercular serodiagnosis. We analysed sera samples from 30 subjects with active tuberculosis (TB+), 30 with latent tubercular infection (LTBI) and 60 healthy subjects as controls (K). Our data indicated a good antibody response of the TB+ and LTBI patients against the phage Ri(7)17; the optical density (OD) values obtained from sera patients was statistically significant when compared to the control samples. Our results confirm that phage display technology might be useful to develop new tools for diagnosis of tuberculosis.

Cyanobacterial distributions are shaped by abiotic factors including temperature, light and nutrient availability as well as biotic factors such as grazing and viral infection. In this study, we investigated the abundances of T4-like and T7-like cyanophages and the extent of picocyanobacterial infection in the cold, high-nutrient-low-chlorophyll, sub-Antarctic waters of the southwest Pacific Ocean during austral spring. Synechococcus was the dominant picocyanobacterium, ranging from 4.

Foodborne viruses are significant contributors to global food safety incidents, posing a serious burden on human health and food safety. In this study, a multiplex reverse transcription-droplet digital PCR (RT-ddPCR) assay based on the MS2 phage as a process control virus (PCV) was developed to achieve the simultaneous detection of hepatitis A virus (HAV) and hepatitis E virus (HEV) in bivalve shellfish. By optimizing the reaction system and procedures, the best reaction conditions were selected, and the specificity, sensitivity, and reproducibility of the method were assessed.

Recently, we developed a spatial phage-assisted continuous evolution (SPACE) system. This system utilizes chemotaxis coupled with the growth of motile bacteria during their spatial range expansion in soft agar to provide fresh host cells for iterative phage infection and selection pressure for preserving evolved genes of interest carried by phage mutants. Controllable mutagenesis activated only in a subpopulation of the migrating cells is essential in this system to efficiently generate mutated progeny phages from which desired individuals are selected during the directed evolution process.

Archaeal peptidoglycan, a crucial component of the cell walls of Methanobacteria and Methanopyri, enhances the tightness of methanogenic cells and their resistance to known lytic enzymes and antibiotics. Although archaeal peptidoglycan endoisopeptidases (Pei) can reportedly degrade archaeal peptidoglycan, their biochemistry is still largely unknown. In this study, we investigated the activity and catalytic properties of the endoisopeptidases PeiW and PeiP using synthesized isopeptides identical to natural substrates.

Influenza remains a persistent global health challenge, largely due to the virus' continuous antigenic drift and occasional shift, which impede the development of a universal vaccine. To address this, the identification of broadly neutralizing antibodies and their epitopes is crucial. Nanobodies, with their unique characteristics and binding capacity, offer a promising avenue to identify such epitopes.
