Abstract Background The prevalence of gastrointestinal (GI) neoplastic polyps in Jack Russell terriers (JRTs) has increased Japan since the late 2000s. Recently, we demonstrated that JRTs with GI harbor identical germline variant APC gene (c.[462_463delinsTT]) heterozygous state. Thus, this disease is an autosomal dominant hereditary disorder. Although affected have distinct features, such as d...

Abstract. The purpose of the research Was to study genetic diversity bovine leukemia virus isolates obtained in Belgorod Region using restriction fragment length polymorphism method (RFLP). Scientific novelty. Bovine leukosis is one most common chronic infectious diseases cattle many countries world, which causes significant economic losses livestock industry. typing (BLV), its structure, evalu...

background and objectives : in iran, anaplasmosis is normally diagnosed with traditional giemsa staining method. this is not applicable for identification of the carrier animals. the aim of this study was to compare the detection of anaplasma marginale in two different numbers of microscopic fields (50 and 100) using conventional giemsa staining method compared with the pcr-rflp technique. mate...

BACKGROUND The intergeneric hybrids between Ascocenda John De Biase 'Blue' and Phalaenopsis Chih Shang's Stripes have been generated to introduce the blue color into the Phalaenopsis germplasm in prior study. In order to confirm the inheritance in hybrid progenies, genomic in situ hybridization (GISH) and restriction fragment length polymorphism (RFLP) analysis were conducted to confirm the int...

A cross-sectional study was carried out in the Ghibe valley from August to October 2010. 411 head of cattle were sampled in eight villages for buffy coat examination (BCE) and blood spots were collected from each animal for trypanosomose diagnosis by 18S-PCR-RFLP and diminazene aceturate (DA) resistance by Ade2-PCR-RFLP. Three villages were selected in a zone where trypanosomosis control operat...

This work includes, identification eight species of Aphids (Homoptera: Aphididae) which collected from the leaves different plants in many localities Erbil governorate Kurdistan region-Iraq period May till July 2022, these are: Chaitophorus salijaponicus, Aphis fabae, Macrosiphum rosae, Capitophorus carduinus, Myzus persicae, ruborum, punca, and gossypii. The mitochondrial cytochrome C Oxidase ...

in this study, substitution at codon ser315 of katg gene, a reliable marker for isoniazid (inh) resistance was analyzed and compared by three molecular methods such as dna sequencing, polymerase chain reaction restriction fragment length polymorphism (pcr-rflp) and pcr-single strand conformation polymorphism (pcr-sscp) in 105 phenotypically resistant isolates obtained from various parts of indi...

AIM To look for a rapid low-cost technique for the detection of HBV variants. METHODS Two patients who underwent orthotopic liver transplantation (OLT) for HBV infection were treated with lamivudine (100 mg daily) and HBV infection recurred in the grafted livers. The patients were monitored intensively for liver enzymes, hepatitis B surface antigen (HBsAg) and HBV DNA in serum. Liver biopsy w...
