Development of a Real-Time Recombinase Polymerase Amplification Assay for the Rapid Detection of African Swine Fever Virus Genotype I and II.

African swine fever (ASF) is a contagious viral disease in pigs and wild boars which poses a major threat to the pig industry. Rapid and accurate diagnosis is necessary to control ASF. Hence, we developed a rapid diagnostic method using a recombinase polymerase amplification (RPA) assay targeting the conserved sequences of CP204L (p30) thatcan rapidly detect ASF virus (ASFV) genotype strains I and II.

Shedding and extensive and prolonged environmental contamination of goat farms of Q fever patients by Coxiella burnetii.

Background: A majority (>70%) of Q fever patients in South Korea do not have a history of animal contact. Therefore, unconscious environmental exposure is suspected. The aim of this study was to investigate exposure of Q fever patients to environmental contamination and animal shedding.

Molecular and genomic features of strain 1595 isolated from Korean cattle.

The aim of this study was to investigate the molecular characteristics and to conduct a comparative genomic analysis of strain 1595 isolated from a native Korean cow. Molecular typing showed that 1595 has spoligotype SB0140 with mycobacterial interspersed repetitive units-variable number of tandem repeats typing of 4-2-5-3-2-7-5-5-4-3-4-3-4-3, representing the most common type of in Korea. The complete genome sequence of strain 1595 was determined by single-molecule real-time technology, which showed a genome of 4351712 bp in size with a 65.

Seroprevalence of tuberculosis in domesticated elk (Cervus canadensis) in Korea.

Tuberculosis is a contagious disease in animals, primarily cattle, although it also affects wild animals and humans. There are few data on the state of tuberculosis in domesticated elk (Cervus canadensis) in Korea. In order to investigate tuberculosis in elk, the effectiveness of an enzyme linked immunosorbent assay (ELISA) using MPB70 and MPB83 antigens was compared with the tuberculin skin test (TST), and seroprevalence was measured with this assay using serum samples collected from domesticated elk herds in Korea.

Complete Genome Sequence of Mycobacterium bovis Clinical Strain 1595, Isolated from the Laryngopharyngeal Lymph Node of South Korean Cattle.

Mycobacterium bovis strain 1595 was isolated from the lymph node of South Korean native cattle. The complete genome sequence of strain 1595 was determined in 2 contigs and was found to be 4,351,712 bp in size, with a 65.64% G+C content and 4,358 predicted protein-coding genes.

Performance of the SD Bioline TB Ag MPT64 Rapid test for quick confirmation of Mycobacterium bovis isolates from animals.

Mycobacterium (M.) bovis, a bacterium in the M. tuberculosis complex, is a causative agent of bovine tuberculosis, a contagious disease of animals.
