Fusarium verticillioides, F. proliferatum, and F. meridionale were identified as the predominant fungi among 116 Fusarium isolates causing maize ear and kernel rot, a destructive disease in Chongqing areas, China. The toxigenic capability and genotype were determined by molecular amplification and toxin assay. The results showed that the key toxigenic gene FUM1 was detected in 47 F. verticillio...

BACKGROUND/PURPOSE To investigate the characterization of bla(OxA-23) gene regions in isolates of Acinetobacter baumannii from Taizhou Municipal Hospital. METHODS Fifty-nine non-repetitive, multiresistant (including imipenem-resistant) isolates of A. baumannii were recovered from clinical infections in hospitalized patients from January 2010 to August 2011 in Taizhou Municipal Hospital (affil...

Fusariosis is an emerging opportunistic mycosis against which currently used antifungals have limited activity. Here, we investigated the in vitro activities of pentamidine (PNT) against 10 clinical isolates of Fusarium species (five Fusarium solani isolates and five non-F. solani isolates) by using the National Committee for Clinical Laboratory Standards microdilution method in three different...

Mycobacterium avium subsp. hominissuis (MAH) causes disease in both humans and swine; however, the genetic variations in MAH isolates are unclear. The aim of this study was to elucidate the genetic variations in MAH isolates from humans and swine in Japan. We analysed the 16S-23S rDNA internal transcribed spacer (ITS) sequence and variable number of tandem repeats (VNTRs) using the Mycobacteriu...

Some members of the familyClavicipitaceae are endophytic and have mutualistic relationship with the plant family Poaceae. Their relationship is beneficial for both host and fungus. In the present investigation, endophytic fungi were isolated from seed and leaf sheath of hosts Festuca arundinacea, F. ovina, F. pratensis, Bromus tomentellus, Melica persica and Lolium prenne. Morphological charact...

Nosocomial isolates of Pseudomonas aeruginosa and Acinetobacter spp. exhibit high rates of resistance to antibiotics and are often multidrug resistant. In a previous study (D. Milatovic, A. Fluit, S. Brisse, J. Verhoef, and F. J. Schmitz, Antimicrob. Agents Chemother. 44:1102-1107, 2000), isolates of these species that were resistant to sitafloxacin, a new advanced-generation fluoroquinolone wi...

15 Production of OXA-23 carbapenemase is the most common reason for the increasing 16 carbapenem resistance in Acinetobacter spp. This study was conducted to reveal the genetic 17 basis of the blaOXA-23 dissemination in Acinetobacter spp. in China. A total of sixty-three 18 carbapenem-resistant OXA-23-producing Acinetobacter spp. isolates, representing different 19 backgrounds, were selected fr...

Fusarium solain is the most important pathogen of huge range of plant hosts, especially potato in the word, which causes tuber rot in storage and root rot of potato plants in fields. Fifty four isolates from potato, bean, chickpea and cucurbit (melon, watermelon and cucumber) was subjected in a study through analysis of vegetative compatibility groups (VCGs) and rep-PCR DNA fingerprinting. Nit ...

Five Fusarium graminearum and 12 F. culmorum isolates, primarily pathogenic species of Fusarium head blight, were obtained from naturally infected wheat from various agro-ecological regions of Turkey. Genotyping of the isolates was carried out using random-amplified polymorphic DNA (RAPD). Sixty-five 10-mer oligonucleotide primers were used to amplify the RAPD markers. Among them, 50 primers pr...

The pectic enzymes produced in vitro by 8 isolates (5 Highly virulent and 3 Weakly virulent) of Fusarium oxysporum , were detected by spectrophotometry, and characterized by polyacrylamide gel electrophoresis with substrate-containing gels (zymogram). Analysis of the polygalacturonase (PG) isozyme banding patterns (zymogram) identified two distinct phenotypes among the isolates from chickpea (C...
