In addition to intrinsic resistance in Acinetobacter baumannii, many different types of acquired resistance mechanisms have been reported, including the presence of VIM and IMP metallo β-lactamases and also of blaOXA-23-like and blaOXA-58-like enzymes. In the Kurdistan region of Iraq, the multiresistant A. baumannii-calcoaceticus complex is prevalent. We characterized the different mechanisms o...
background: identification and quantification of mycotoxins produced by fusarium species are important in controlling fungal diseases. objectives: potential of zearalenone, butenolide and fusarin c production was investigated in five fusarium graminearum and five f. culmorum isolates at molecular level. materials and methods: presence of pks13, fg08079.1 and pks10 genes, associated with product...
BACKGROUND: Colibacillosis is one of the most prevalentdiseases in the world that causes multimillion-dollar annuallosses. OBJECTIVES: In order to evaluate molecular epidemiologyof some virulence associated factors in Escherichia coli,isolated from poultry, the presence of iut A, iss, hly F, omp T, iroN, afa, sfa (S)and pap G (II) were investigated by multiplex PCRassay. METHODS: Two hundred th...
Crown disease (CD) is infecting oil palm in the early stages of the crop development. Previous studies showed that Fusarium species were commonly associated with CD. However, the identity of the species has not been resolved. This study was carried out to identify and characterize through morphological approaches and to determine the genetic diversity of the Fusarium species. 51 isolates (39%) ...
Understanding genetic structure and status of genetic variation of Fasciola hepatica isolates from different hosts, has important implications on epidemiology and effective control of fasciolosis. Random amplified polymorphic DNA (RAPD-PCR) was used to study the genetic variation of F. hepatica in sheep and cattle. DNA was extracted from adult helminthes removed from livers of each infected ani...
despite routine vaccination programs against newcastle disease (nd), sporadic cases have occasionally occurred that remain a constant threat to commercial poultry. ten isolates of newcastle disease viruses (ndv) from infected broiler chicken cases were obtained from various locations in fars province during 2009-2011 and genetically analyzed using reverse transcription polymerase chain reaction...
16 Routine application of antimicrobials is the current treatment of choice for rainbow trout 17 fry syndrome (RTFS) or bacterial coldwater disease (BCWD) caused by Flavobacterium 18 psychrophilum. In this study, the antimicrobial susceptibilities of 133 F. psychrophilum 19 isolates, 118 of which were from the UK, were evaluated by broth microdilution and disc 20 diffusion methods following VET...
