One-hundred eight Mycobacterium avium isolates from pigs, humans, birds, and bovines were typed by the IS1245-based restriction fragment length polymorphism (RFLP) method and PCR-restriction enzyme analysis (PRA) of hsp65. Nine clusters of isolates showing more than 80% similarity in their RFLP profiles were detected. The largest cluster (cluster B) included 32 of 79 pig isolates (40.5%), 3 of ...

biochemical polymorphism study is a method of determination of genetic variation. this variability could be a basis for selection and subsequent genetic improvement in farm animals. the polymorphism in the intron 1 of chicken growth hormone (cgh) gene was investigated in the iranian native fowls by using polymerase chain reaction (pcr)-restriction fragment length polymorphism (rflp) method. the...

Background & Aims: To investigate the association of CFI p.Gly119Arg polymorphism with Age-related macular degeneration (AMD). Materials & Methods: In this case-control study, the association of p.Gly119Arg polymorphism in CFI gene was investigated in 65 patients suffering from AMD and150 healthy age, sex and ethnicity matched unrelated people as control group. Both of the case and cont...

Molecular typing of twenty-five Pasteurella multocida isolates has been assessed by restriction fragmentlength polymorphism (RFLP) of a species-specific PCR assay. Amplification was based on the gene ompH, encoding a major outer memberane protein. RFLP analysis of the 1.2 kb ompH-amplification usingEcoRI, HindIII and CfoI endonucleases produced 7 different patterns for the twenty fi...

Background: Androgens have an anti-proliferative effect on endometrial cells. Human androgen receptor (AR) gene contains two polymorphic short tandem repeats of GGC and CAG, and a single-nucleotide polymorphism on exon 1 that is recognized by the restriction enzyme, StuI. Prior studies have shown that the lengths of the CAG and GGC repeats are inversely and linearly related to AR activity and a...

Neovascular Age-related Macular Degeneration (nAMD) is one of the major factors for blindness and impaired visual acuity in elderly people. The aim this study was CFH gene screening Age-Related patients Indonesia. This performed 106 AMD 104 controls genomic markers Complement Factor H ( ). diagnosis carried out by retinal specialists based on color fundus photography optical coherence tomograph...

the genetic variation and population structure of narrow-clawed crayfish (astacus leptodactylus) was examined by means of polymerase chain reaction (pcr) restriction fragment length polymorphism (rflp) analysis of the cytochrome oxidase subunit i (coi) of mitochondrial dna. a total of 194 adult specimens were collected from seven sample sites including, two in the south caspian sea and one each...

The geographical distribution of the Brazilian endemic stingless bee Melipona quadrifasciata quadrifasciata Lepeletier ranges from Rio Grande do Sul to Minas Gerais states. The objective of the present study was to verify mtDNA polymorphisms among samples of M. q. quadrifasciata collected in southern Brazil. Twenty nine colonies from three localities (Blumenau and Mafra/SC and Prudentópolis/ PR...
