شناسایی گونه‌های مالاسزیای جداشده از بیماران مبتلا به پیتیریازیس ورسیکالر با استفاده از روش PCR-RFLP
Background and Aim: Malassezia is a lipophilic and dimorphic fungus which has different species. Some of them can be found as natural flora on skin and in some conditions may cause pityriasis versicolor. The aim of this study was to identify Malassezia species associated with pityriasis versicolor in Iranian patients, using PCR-RFLP.Methods: In this study out of 65 patients with pityriasis vers...
گوشت طیور یکی از مهمترین عوامل انتقال عفونت سالمونلایی در انسان می باشد. کشت و جداسازی سالمونلا از نمونه ماده غذایی از طریق کشت باکتریولوزیک و سنتی مستلزم صرف 4-6 روز می باشد. روش pcr به علت دقت و سرعت بالای آن یک روش جایگزین مناسب برای تشخیص های میکروبیولوژیکی شناخته شده است. در این مطالعه مقدماتی میزان آلودگی لاشه طیور گوشتی به باکتری جنس سالمونلا و گونه انتریتیدیس مورد ارزیابی قرار گرفت. تعد...
Objective(s):blaCTX-Mand blaPER are two genes that encode class A extended-spectrum β-lactamases (ESBLs) and can be responsible for therapeutic problems. This study was carried out to evaluate the molecular properties of these genes in clinical isolates of Enterobacteriaceae by polymerase chain reaction (PCR), restriction digestion and sequencing. Materials and Methods: During six months, start...
A multiplex PCR designed to differentiate Mycobacterium tuberculosis complex organisms from M. avium and M. intracellulare was used to test 105 isolates identified by DNA probe methods as M. avium, M. intracellulare, or M. avium complex type X. The multiple PCR correctly identified 33 of 34 isolates identified by commercial probe methods as M. avium and all 51 isolates identified as M. intracel...
BACKGROUND & OBJECTIVE Mycoplasma pneumoniae is known to be a major cause of lower respiratory tract infections in children. A specific diagnosis is important to institute the appropriate treatment. Information on diagnostic methods used for M. pneumoniae in Indian paediatric population is scarce. The study was thus conducted to compare polymerase chain reaction (PCR), culture and serology for ...
Macrophage colony stimulating factor (M-CSF) has previously been shown to affect the differentiation of cells of the mono-nuclear phagocytic line. More recent studies indicate that M-CSF may have a role in pregnancy. In the present study, the expression of M-CSF in the human placenta was demonstrated. Placental mRNA was isolated and used as template for synthesis of complementary DNA (cDNA). Th...
Ichthyozoonotic Mycobacterium spp. poses health risks both to fish and humans. In this study, the presence of ichthyozoonotic Mycobacterium spp. was investigated in red mullet (Mullus barbatus barbatus) and surmullet (Mullus surmuletus), widely caught species in the Mediterranean and the Aegean Sea. A total of 208 fish samples, provided from fishermen of Mersin province (Turkey) were studied. U...
Although Mycoplasma equigenitalium has been implicated in equine reproductive problems, its prevalence is largely unexplored due to the lack of specific diagnostic tests. To address this limitation, the authors developed and optimized species-specific primer pairs that target M. eguigenitalium rpoB (RNA polymerase B subunit) gene sequences. The specificity of the PCR assay developed in this stu...
