BACKGROUND Single-nucleotide polymorphism (SNP) analysis is a powerful strategy for large-scale molecular population studies examining phylogenetic relationships among bacterial strains. Mycobacterial interspersed repetitive units-variable number of tandem repeats (MIRU-VNTR) can be easily digitized to share data among laboratories. This study applied SNP and MIRU-VNTR analyses for molecular st...

Fusarium head blight (FHB) is one of the most economically important and destructive fungal diseases of wheat (Triticum aestivum L.). Golestan province, one of the most important zones of wheat cultivation in Iran, is also known for its high rate of digestive tract cancer, which has been attributed to many biotic factors such as fungal toxins. In order to investigate the distribution of toxicog...

ABSTRACT Fusarium species can cause severe root disease and damping-off in conifer nurseries. Fusarium inoculum is commonly found in most container and bareroot nurseries on healthy and diseased seedlings, in nursery soils, and on conifer seeds. Isolates of Fusarium spp. can differ in virulence; however, virulence and colony morphology are not correlated. Forty-one isolates of Fusarium spp., mo...

Carbapenem-resistant Acinetobacter baumannii (CR-AB) represents a major health-care problem, causing high rates of morbidity and mortality. This study investigated the clonality of CR-AB isolated from diabetic patients from different regions in Saudi Arabia, as well as the relatedness of the β-lactamase genes. A total of 64 non-repetitive CR-AB clinical isolates were collected from 16 different...

background: fasciola species are parasitic trematode with world wide distribution that infects wild and domesticated herbivores, particularly ruminants. the aim of the present study was to investigate the intra species variations of f. gigantica, from goats and buffalos isolates in two common geographic climates of iran. methods: fasciola species were collected from goat, buffalo, sheep, and ca...

ObjectivesWe described the prevalence of clofazimine (CFZ) resistance in a multidrug-resistant tuberculosis (MDR-TB) cohort China. We also aimed to identify dynamic changes CFZ susceptibility and its molecular mechanism after exposure bedaquiline (BDQ) and/or CFZ.MethodsThe experimental settings were conducted based on our MDR-TB receiving BDQ-containing regimens. Sequential isolates obtained f...

We investigated the resistance determinant of 13 clinical isolates of carbapenem-resistant Acinetobacter baumannii collected from a regional hospital in the north of Thailand. All isolates were multidrug resistant and produced the OXA-23 carbapenemase. The bla(OXA-23) gene was found adjacent to ISAba1. Furthermore, two isolates carried the metallo beta-lactamase gene, bla(IMP). The bla(OXA-23) ...

Thirty-two isolates of Fusarium from Hawaiian Acacia koa exhibiting wilt/dieback disease symptoms were compared for their pathogenic potential on young Douglas-fir germinants in controlled laboratory tests. Only three isolates (one each of F. oxysporum, F. solani, and F. subglutinans) exhibited low virulence. All others, including isolates of F. semitectum and F. equiseti, were non-pathogenic. ...

An alarming increase in the resistance rates of tigecycline and colistin among carbapenemase-producing Acinetobacter baumannii recovered from a Greek hospital over a 3-year period (2011-2013) was investigated. The antimicrobial resistance profiles and carbapenemase gene content were determined for a collection of colistin- and/or tigecycline-resistant carbapenemase-producing A. baumannii isolat...
