ABSTRACT Cystic fibrosis (CF) and inflammatory bowel disease (IBD) represent distinct pathologies with unique genetic underpinnings; yet, they share remarkable similarities in gut microbiota dysbiosis and intestinal phys...

ABSTRACT The Com_YlbF domain-containing proteins inhibit sporulation, competition, and biofilm formation by affecting the activity of ribonuclease RNase-Y in Bacillus subtilis. Similar Com_YlbF proteins are found in Stap...

ABSTRACT Antimicrobial recalcitrance is a growing problem in today’s world. Not only are bacteria developing resistance at an alarming pace but the antibiotic discovery pipeline has gone dry, making antimicrobial stewa...

ABSTRACT Mycoplasma bovis is a highly infectious pathogenic microorganism that causes various clinical signs in cattle, including pneumonia, arthritis, and mastitis, often resulting in significant economic losses. The ad...

ABSTRACT Transcriptional regulation of metabolic operons is important for optimal carbohydrate use and for mitigating the accumulation of toxic intermediates. Here, we characterize SL1344_3500, encoding a putative IclR-l...

ABSTRACT Many bacteria produce flagella to swim and navigate through environments. Depending on the species, flagella are beneficial for other activities such as sensing surfaces to initiate biofilm development, secretio...

ABSTRACT Leprosy is a chronic infectious disease caused by Mycobacterium leprae and M. lepromatosis. Brazil consistently ranks among the countries with the highest number of leprosy cases. Data from our group showed that...

ABSTRACT Carbapenem resistance mediated by blaNDM-encoded metallo-beta-lactamases is often linked to ISAba125, an insertion sequence from the IS30 family, which is widely distributed among critical and high-priority bact...

ABSTRACT Increased susceptibility of elderly populations to infection is a major concern, as recently experienced by the coronavirus pandemic. Therefore, the treatment of infected elderly individuals is of immediate inte...

Bone infection is a severe disease caused by microbial invasion of bone tissue, characterized by inflammatory responses, bone destruction, and impaired repair. Its high recurrence rate and refractory nature have posed si...

ABSTRACT Protein trafficking from the cytosol to specific sites of action is a fundamental process for bacterial survival and growth. In the monoderm gram-positive bacteria, this process involves traversing the cytoplasm...

ABSTRACT In Bacillota, quorum sensing can be mediated by RRNPP regulators that are activated by autoinducing peptides (AIPs). In this study, we derived a hidden Markov model profile from a 3D-informed alignment to establ...

ABSTRACT The bacterial flagellar filament acts as a propeller to drive most bacterial swimming. The filament is made of flagellin, known as FliC in Escherichia coli. FliC consists of four domains, the highly conserved co...

ABSTRACT Staphylococcus aureus is a common upper respiratory tract (URT) pathobiont with high carriage rates in the upper airway disease chronic rhinosinusitis (CRS). CRS is associated with increased prevalence and abund...

ABSTRACT Staphylococcus epidermidis, a ubiquitous inhabitant of human skin, has been known for decades for its capacity to form biofilm-associated infections on indwelling medical devices and has developed into a leading...

ABSTRACT Phthalates such as isophthalate, phthalate, and terephthalate are widespread environmental pollutants with significant health and ecological impacts. Comamonas testosteroni KF1 initiates isophthalate degradation...

ABSTRACT Chlamydia trachomatis has a DNA topoisomerase I with a unique C-terminal domain (CTD) homologous to eukaryotic SWIB domains. This study focused on determining the function of the SWIB domain-containing TopA from...

ABSTRACT Bacteria can change morphology in response to stressors and changes in their environment, including infection of a host. We previously identified the bacterial species, Bordetella atropi, which uses nutrient-ind...

ABSTRACT The Hna phage defense system is one of many systems that protect bacteria against bacterial viruses (phages). Hna was first discovered in the nitrogen-fixing alphaproteobacterium Sinorhizobium meliloti, which fo...

Antimicrobial resistance represents a major global health challenge, particularly in the context of multidrug-resistant bacteria. Although conventional antibiotics and antimicrobial peptides (AMPs) both exert selective p...

A set of oligonucleotide primers capable of initiating enzymatic amplification (polymerase chain reaction) on a phylogenetically and taxonomically wide range of bacteria is described along with methods for their use and ...

La infección urinaria (IU) y su manifestación clínica, la descarga vulvar (DV) es considerada una de las causas de descarte y muerte de hembras porcinas. En la República Argentina la información referente a IU y DV ...
