Routine detection of equine arteritis virus (EAV) can be achieved by virus isolation (VI) in cell culture, or by the amplification of viral genome by molecular methods. To simplify molecular diagnosis, a number of different Reverse Transcriptase Polymerase Chain Reaction (RT-PCR) and RT-nested PCR (RT-nPCR) assays were compared, and a one-tube method was developed and optimised utilizing a fluo...
background: giardia lamblia is one of the most prevalent intestinal flagellate protozoa that infects a wide range of vertebrate hosts causing severe intestinal disorder in children.this study was performed to determine subspecies of g.lamblia by the pcrrflp method, targeting the glutamate dehydrogenase (gdh) locus, in hospitalized children at urmia mutahhari hospital, west azerbaijan province,i...
Background & Aims : Giardia lamblia is one of the most prevalent intestinal flagellate protozoan that infects a wide range of vertebrate hosts . Giardia is one of the most common intestinal pathogens in children causing sever intestinal disorder and growth retardation. This study was performed to determine subspecies of Giardia lamblia by the PCR-RFLP method, targeting the glutamate dehydro...
introduction acetic acid bacteria are large group of obligate aerobic gram negative bacteria with the ability to oxidize ethanol to acetic acid (1). they are widely distributed in natural habitats and classified in family acetobacteraceae. members of this family are useful in industrial production of vinegar(2). acetic acid bacteria (aab) can use substrates as glucose, ethanol, lactate or glyc...
Background: White spot syndrome virus (wssv) is the causing agent for white spot disease in shrimp and many crustaceans. This disease is highly contagious and can cause death within 3–10 days under normal culture conditions. Therefore, early diagnosis of the virus is a necessity. Materials and Methods: Primers were designed for three regions of the virus genome and one region of the shrimp geno...
Nowadays, non-albicans Candida are common in human pathogens, and some of these cases were found in milk in the present study. Thanks to its various minerals and vitamins, milk is a good food source for humans and an ideal environment for the growth of microorganisms, including bacteria and fungi. Also, it is an important product in the agricultural sector. Materials and Methods: In the presen...
AIMS Clonality analysis using polymerase chain reaction (PCR) amplification of the immunoglobulin heavy chain (IgH) gene is an important aid to the diagnosis of B cell lymphoproliferative diseases. However, the method has a relatively high false negative rate. In an attempt to improve detection rates simple PCR strategies for clonality analysis of B cell populations using amplification of Ig li...
background and aims: the aim of present study was to investigate the molecular characteristic of staphylococcus aureus to detect mec a gene and to type sccmec in strain isolated from healthy worker at larestan hospital. material and methods: this study was carried out from the 250 nasal swab healthy worker at larestan hospital. multiplex polymerase chain reaction for meca gene was performed in...
BACKGROUND The Polymerase Chain Reaction (PCR) technique has been frequently used in the molecular diagnosis of leprosy. OBJECTIVES To compare the results of PCR with four pairs of Mycobacterium leprae specific primers as well as to compare these results to multibacillary (MB) and paucibacillary (PB) leprosy according to the WHO operational classification. METHOD 28 DNA samples, collected f...
A survey was conducted to ascertain the distribution and virulence of Aeromonas spp. (species) in carabeef and mutton samples in Greater Hyderabad Municipal Corporation, India. Conventional method using Aeromonas isolation medium and Ampicillin Dextrin agar, PCR targeting 16S rRNA were used to identify Aeromonas spp. in meat samples. Conventional cultural method revealed 28% and 40% positives i...
