Mycobacterium avium subsp. paratuberculosis is the etiologic agent of Johne's disease and is endemic to the national cattle herds of many countries. Because of the very low level of genetic heterogeneity of this organism, it is difficult to select a workable procedure for strain differentiation at a resolution sufficient to investigate epidemiological links between herds or different ruminant s...
Abstract: The non-tuberculous mycobacteria (NTM) are ‘atypical mycobacteria’ belonging to species other than those classified in the Mycobacterium tuberculosis complex. NTM have been reported cause cross-reactive immune responses that interfere with diagnosis of both livestock and wildlife considered as potential pathogens for animals humans. present study was conducted detection non- tuberculo...
BACKGROUND Due to the differences in the oncogenic activity of human papillomaviruses (HPV), it is clinically important to accurately identify HPV types in a simple and time effective manner. OBJECTIVES We aimed at developing a straightforward and cost-effective assay to individually identify all mucosal HPVs, based on the amplification of L1 gene using MY09/11 primers, and subsequent restric...
In the present investigation, 49 Aspergillus fumigatus isolates obtained from four nosocomial outbreaks were typed by Afut1 restriction fragment length polymorphism (RFLP) analysis and three PCR-based molecular typing methods: random amplified polymorphic DNA (RAPD) analysis, sequence-specific DNA primer (SSDP) analysis, and polymorphic microsatellite markers (PMM) analysis. The typing methods ...
background: fusarium species are capable of causing a wide range of crop plants infections as well as uncommon human infections. many species of the genus produce mycotoxins, which are responsible for acute or chronic diseases in animals and humans. identification of fusaria to the species level is necessary for biological, epidemiological, pathological, and toxicological purposes. in this s...
background: fusobacterium necrophorum as a non-spore-forming gram-negative anaerobic bacillus is an important human and animal pathogen. it may cause severe systemic infections (lemierre's syndrome) and some other infections. the aim of this study was to subtype fusobacterium necrophorum by using pcr methods. materials and methods: twenty five strains of fusobacterium necrophorum subspecies fun...
Staphylococcus aureus is a major pathogen in the transmission of diseases from animals to humans and vice-versa.Various infections, such as mastitis in cattle, sheep and goats, as well as gastroenteritis due to food poisoning in humans are the most frequent problems caused by S. aureus. The bacteria also lead to severe economic losses in dairy industry. A major virulence facto...
conclusions the outcome of this study indicates a higher discriminatory power of the rflp analysis based on the spa gene compared to the coa gene. moreover, the results of our study reveal that the resistance rate of s. aureus to some antimicrobial agents including linezolid is a growing concern. background antibiotic resistant staphylococcus aureus is a serious public health problem worldwide....
