    A new finding is reported of multiple mutations in the rpoB gene of 9 Mycobacterium leprae strains from leprosy patients in Thailand, who did not respond to therapy even when rifampicin, the main drug in multi-drug therapy was used. By means... of sequence analysis of 9 Thai M. leprae strains, various mutations in 289 bps of the rpoB gene revealed forms of mutation never before described, such as multiple mutations (ie, mutation at two, three, six, seven, eight and nine positions in the rpoB gene

    sand flies were then identified to species level using molecular techniques. Subsequent analyses included the detection of pathogens and the identification of pyrethroid resistance mutations within the voltage-sensitive sodium channel (Vgsc) domain IIS6..., or F1020S mutations were detected in Vgsc gene. Conclusions: The results of this study provide valuable information on sand fly species and the continuous circulation of Leishmania spp. and Trypanosoma spp. in Songkhla, southern Thailand. Moreover

    Comparative Genomic Analysis and a Novel Set of Missense Mutation of the Leptospira weilii Serogroup Mini From the Urine of Asymptomatic Dogs in Thailand
    (2021-10-18) Alongkorn Kurilung; Vincent Perreten; Nuvee Prapasarakul; Siriraj Hospital; Chulalongkorn University; University of Bern
    Leptospira weilii belongs to the pathogenic Leptospira group and is a causal agent of human and animal leptospirosis in many world regions. L. weilii can produce varied clinical presentations from asymptomatic through acute to chronic infections... into the missense mutations, focusing on the known pathogenesis-related genes. Whole genome sequences revealed that the CUDO6 and CUD13 strains each contained two chromosomes and one plasmid, with average genome size and G+C content of 4.37 Mbp and 40

Several human patients with mutations in XRCC4 were reported to exhibit microcephaly and growth defects, but unexpectedly showed normal immune function. Here, to evaluate the functionality...Non-homologous end joining is one of the main pathways for DNA double-strand break (DSB) repair and is also implicated in V(D)J recombination in immune system. Therefore, mutations in non-homologous end-joining (NHEJ) proteins were found

    Transferable plasmid-mediated resistance to linezolid due to cfr in a human clinical isolate of Enterococcus faecalis
    (2012-07-01) Lorena Diaz; Pattarachai Kiratisin; Rodrigo E. Mendes; Diana Panesso; Kavindra V. Singh; Cesar A. Arias; University of Texas Medical School at Houston; Universidad El Bosque; Mahidol University; JMI Laboratories Incorporated
    Nonmutational resistance to linezolid is due to the presence of cfr, which encodes a methyltransferase responsible for methylation of A2503 in the 23S rRNA. The cfr gene was first described in animal isolates of staphylococci, and more recently..., it has been identified in Staphylococcus aureus from human clinical infections, including in an outbreak of methicillin-resistant S. aureus. In enterococci, cfr has been described in an animal isolate of Enterococcus faecalis from China. Here, we report

    drugs that we do have available. Although in experimental animals combinations have been shown unequivocally to delay the onset of resistance, this has not yet been proved formally in human malaria. Yet formal proof is extremely difficult to obtain... antimalarial drugs. Those drugs with a particularly vulnerable profile, in which a single or double point mutation confers high level resistance, should not be deployed alone and should always be combined with an artemisinin derivative.

    Activation of GABA transmission by clonazepam reverses the autistic-like phenotypes of the Cav3.2 knockout mice

    , animal and molecular studies investigating the underlying mechanism in ASD patients with CACNA1H mutations are lacking. In this study, we performed a series of behavioral assays to phenotype the Cav3.2 systemic knockout (Cav3.2KO) mice. The Cav3.2KO mice.... To date, there are no disease-modifying, mechanism-targeted treatments approved for core ASD symptoms. In human studies, loss-of-function mutations in the CACNA1H gene, which encodes the T type Cav3.2 calcium channel, have been associated with ASD. However
