AI Article Synopsis

  • Genotyping of infected animals in South Korea using multispacer sequence typing (MST) and multiple locus variable number tandem repeat analysis (MLVA) was successfully performed for the first time.
  • The results indicated that all strains had the same MLVA genotype of 6-13-2-7-9-10 and MST genotype group 61, which match those previously found in Poland.
  • The detection of this MLVA type in humans in France raises concerns about the potential for the Korean strain to cause Q fever in humans, highlighting the importance of MST and MLVA in tracking epidemiological relationships across regions.

Article Abstract

Genotyping of using multispacer sequence typing (MST) and multiple locus variable number tandem repeat analysis (MLVA) was conducted from infected animals for the first time in the Republic of Korea. was detected by real-time PCR, and followed by MST and MLVA genotyping. The result showed that detected all had the same MLVA genotype, 6-13-2-7-9-10 for markers MS23-MS24-MS27-MS28-MS33-MS34, respectively, and genotype group 61 for MST. The same genotypes were previously identified in Poland. Importantly, this MLVA type was detected in humans in France, suggesting that the Korean strain can also potentially cause Q fever in humans. MST and MLVA were very useful tools for analyzing the molecular epidemiology of and helpful for interpreting the epidemiological relationship between isolates from domestic and international resources.

Background: Leptospirosis is a widespread zoonosis caused by bacteria in the genus Leptospira. Basic epidemiological information is crucial to mitigating disease risk but is lacking for leptospirosis; notably, the hosts responsible for maintaining Leptospira remain largely unknown. Frequently observed near human habitations, hedgehogs (Erinaceus europaeus) are taken to wildlife rescue centres when found sick or injured.

Article Synopsis
  • * The main diagnostic method is serological testing using immunofluorescence assay (IFA), while PCR tests can also detect bacterial DNA if timed correctly.
  • * The study reports the isolation of a novel strain of Q fever bacteria from a valve specimen using Vero cells, revealing it as a local strain previously unknown in Israel, related to genotype MST6 with the QpRS plasmid.

Genome sequence of KZQ2 isolated from a clinical strain in the Republic of Korea.

Microbiol Resour Announc

September 2023

Department of Bacterial Disease Research, Center for Infectious Disease Research, National Institute of Infectious Disease, Korea National Institute of Health, Korea Disease Control and Prevention Agency , Cheongju-si, Republic of Korea.

The genome of KZQ2, isolated from clinical patients in Korea, is 2.04 MB long. Multispacer types were ST77, and phylogenetic tree analysis showed that KZQ2 is closely related to the CbuK_Q154 chronic strain isolated from human endocarditis patients in the USA.

Article Synopsis
  • Trypanosomes are blood parasites found in various mammals, including rats, which can increase the risk of transmission to humans in areas where these rodents are present.
  • The study aimed to detect Trypanosoma in rats from Nakhon Si Thammarat, Thailand, using both microscopic and molecular methods, collecting 99 blood samples and identifying infections through various techniques, including PCR.
  • Approximately 18% of the rats tested positive for Trypanosoma, specifically T. lewisi, with new genetic sequences documented, highlighting a need for further research on the biology and transmission of this parasite.

, also known as the causal agent of Q fever, is a zoonotic pathogen infecting humans and several animal species. Here, we investigated the epidemiological context of from an area in the Hérault department in southern France, using the One Health paradigm. In total, 13 human cases of Q fever were diagnosed over the last three years in an area comprising four villages.
