Awareness on the spread of carbapenem-resistant Enterobacterales in animals as One Health.

One Health is a multisectoral cooperative and collaborative approach aimed at achieving integrated health by recognizing the interconnectedness of people, animals, plants, and the environment. In the modern world, the One Health approach is considered an essential perspective for overcoming various emerging diseases, including antimicrobial resistance (AMR). One of the top priority AMR infections is caused by carbapenem-resistant Enterobacterales (CRE), which are bacterial strains not susceptible to carbapenems, the last-resort antibiotics for clinical Gram-negative bacterial infections.

Subclinical infection in cattle can be detected using serum MAP antibody enzyme-linked immunosorbent assay (ELISA) and fecal polymerase chain reaction (PCR) tests.

Objectives: To investigate the differences in blood parameters, according to the detection of MAP using serum antibody ELISA and fecal PCR tests.

Effects of synthetic peptide RP557 and its origin, LL-37, on carbapenem-resistant .

is a common bacterium in nosocomial infection. The biofilm-forming ability and antimicrobial resistance make biofilm infection refractory to patients requiring hospitalization, especially patients in the intensive care unit. Therefore, many alternative compounds have been developed.

Safety and Protective Efficacy of a Candidate Vector-Based Vaccine for Bovine Tuberculosis.

This study presents the results of a survey of the safety and protective efficacy of a candidate vector-based vaccine for bovine tuberculosis, using an influenza vector with the NS1 mutation and expressing M. bovis protective antigens ESAT-6 and TB10.4.

Lumpy skin disease as an emerging infectious disease.

Lumpy skin disease (LSD) is one of the most important emerging transboundary diseases. Recently, LSD has emerged in many countries in the northern hemisphere. The LSD virus has a huge genome and is highly resistant to environmental conditions.

Immunopathological mechanisms in the early stage of Mycobacterium avium subsp. paratuberculosis infection via different administration routes in a murine model.

Mycobacterium avium subspecies paratuberculosis (MAP) is the causative agent of Johne's disease, a chronic emaciating disease of ruminants that causes enormous economic losses to the bovine industry, globally. However, there are still remaining clues to be solved in the pathogenesis and diagnosis of the disease. Therefore, an in vivo murine experimental model was tried to understand responses in early stage of MAP infection by oral and intraperitoneal (IP) routes.

A Machine Learning Approach Reveals a Microbiota Signature for Infection with Mycobacterium avium subsp. in Cattle.

Although Mycobacterium avium subsp. (MAP) has threatened public health and the livestock industry, the current diagnostic tools (e.g.

Delineating transcriptional crosstalk between Mycobacterium avium subsp. paratuberculosis and human THP-1 cells at the early stage of infection via dual RNA-seq analysis.

Mycobacterium avium subsp. paratuberculosis (MAP) is the causative agent of Johne's disease, a chronic debilitating disease in ruminants. To control this disease, it is crucial to understand immune evasion and the mechanism of persistence by analyzing the early phase interplays of the intracellular pathogens and their hosts.

Mycobacterium intracellulare induces a Th17 immune response via M1-like macrophage polarization in canine peripheral blood mononuclear cells.

Mycobacterium avium-intracellulare complex (MAC) is one of the most prevalent pathogenic nontuberculous mycobacteria that cause chronic pulmonary disease. The prevalence of MAC infection has been rising globally in a wide range of hosts, including companion animals. MAC infection has been reported in dogs; however, little is known about interaction between MAC and dogs, especially in immune response.

Fetuin as a potential serum biomarker to detect subclinical shedder of bovine paratuberculosis.

Paratuberculosis (PTB) is a chronic contagious granulomatous enteritis of wild and domestic ruminants caused by Mycobacterium avium subsp. paratuberculosis (MAP). PTB causes considerable economic losses to the dairy industry through decreased milk production and premature culling.

Efficacy of bivalent vaccines of porcine circovirus type 2 and in specific pathogen-free pigs challenged with porcine circovirus type 2d.

Background: Porcine circovirus type 2 (PCV2) and (MHP) are economically significant pathogens in the pig industry. The use of combined vaccines against PCV2 and MHP is one of the most effective ways of protecting pigs from both diseases, and it has become a part of general management.

Objectives: This study evaluated the efficacy of two new bivalent vaccines of PCV2 and MHP (Myco-X and Myco-XD) in SPF pigs.

Comparative genomic analysis of plasmids encoding metallo-β-lactamase NDM-5 in Enterobacterales Korean isolates from companion dogs.

Carbapenems are broad-spectrum antibiotics widely used for the treatment of human infections caused by multidrug-resistant (MDR) Gram-negative bacteria. However, emerging carbapenemase-producing Enterobacterales (CPE) are rising as a public threat to human and animal health. We screened clinical bacterial isolates from 241 dogs and 18 cats hospitalized at Veterinary Medical Teaching Hospital, Seoul National University, from 2018 to 2020 for carbapenemase production.

MicroRNA profiling in bovine serum according to the stage of Mycobacterium avium subsp. paratuberculosis infection.

Mycobacterium avium subsp. paratuberculosis (MAP) is the causative agent of Johne's disease (JD), and it causes diarrhea and weakness in cattle. During a long subclinical stage, infected animals without clinical signs shed pathogens through feces.
