Expression Assessment of Some Immunity-related Genes in Buffalo Infected with Endometritis

Othman E. Othman, Dalia A. Taha, Nagwa A. Hassan & Eman R. Mahfouz · Biotechnology Journal International · 2022

Background and Aim: Despite the economic importance of buffalo as a main source of milk and meat, only little attention has been directed to its immune and reproductive performance. The early diagnosis of subclinical endometritis may reduce the economic loss of buffalo’s producti...

Open access Research Article 10.9734/bji/2022/v26i130161

A Study on the Transcriptional Profile of NOS2 and IFN-γ Genes in River Buffalo with Endometritis

Othman E. Othman, Noha M. Osman, Nadia A. Abo El-Maaty & Eman R. Mahfouz · Biotechnology Journal International · 2021

Background and Aim: Uterine lumen contamination with bacteria is ubiquitous in buffalo after parturition. Nearly one-third of these infected animals develop endometritis which leads to reduced fertility. The present study aimed to evaluate the expressions of IFN-γ and NOS2 genes...

Open access Research Article 10.9734/bji/2021/v25i430146

Study on Genetic Polymorphism of IGFBP-3 Gene in Egyptian Buffalo

Othman E. Othman, Ahmed Abou-Eisha & Adel E. El-Din · Annual Research & Review in Biology · 2018

Aim: The present work was carried out to study the genetic characteristics of the IGFBP-3 gene in buffaloes reared in Egypt, where it is considered as one of the important molecular markers for productivity traits like growth and immunity in livestock species. One-hundred animals...

Genetic Structure and Nucleotide Sequences of Three Productivity Trait Genes, in Egyptian Buffalo

Othman E. Othman, Ahmed Abou-Eisha, Adel E. El-Din & Nadia A. Abo El-Maaty · Annual Research & Review in Biology · 2018

One of the main sources of meat and milk in Egypt is buffalo, of river type. The marker assisted selection-depending on the promised genetic markers is considered to be the effective way for improvement of buffalo productivity. This work aimed to study the genetic structure and n...

Open access Research Article 10.9734/ARRB/2018/39001

Cytochrome b Diversity and Phylogeny of Six Egyptian Sheep Breeds

Othman E. Othman, Agnès Germot, Muhammad G. Khodary, Daniel Petit & Abderrahman Maftah · Annual Research & Review in Biology · 2018

Aim: Cytochrome b (Cyt-b) regions of mtDNA have received more attention due to their role in the genetic diversity and phylogenetic studies in different livestock. By using Cytochrome b sequencing, we aimed to clarify the genetic affinities and phylogeny of six Egyptian sheep bre...

Genotyping and Nucleotide Sequences of Growth Hormone Releasing Hormone and Its Receptor Genes in Egyptian Buffalo

Othman E. Othman, Mohamed F. Abdel-Samad, Nadia A. Abo El-Maaty & Karima M. Sewify · Biotechnology Journal International · 2014

Genotyping and Nucleotide Sequences of Growth Hormone Releasing Hormone and Its Receptor Genes in Egyptian Buffalo Aim: The hypothalamic hormone, growth hormone-releasing hormone, is the principal stimulator of pituitary growth hormone (GH) synthesis and secretion. GHRH and its r...

Open access Research Article 10.9734/BBJ/2015/11619

Genetic Characterization of Insulin Growth Factor-1 and Its Receptor Genes in Egyptian Buffalo (Bubalus bubalis L.)

Othman E. Othman, Mohamed F. Abdel-Samad, Nadia A. Abo El Maaty & Karima M. Sewify · Biotechnology Journal International · 2013

Aim: The somatotropic axis (SA) comprises genes associated with economically important quantitative traits in livestock like mammary and muscle growth as well as carcass traits. Insulin growth factor-1 (IGF-1) and its receptor (IGF-1R) are two important genes belonging to the SA....

Polymorphism Evaluation of TLR2 Gene Associated with Endometritis Infection in Buffalo Reared in Egypt

Ahlam A. Abou Mossallam, Noha M. Osman, Othman E. Othman & Eman R. Mahfouz · Biotechnology Journal International · 2022

Background and Aim: Toll-like receptors (TLRs) are important for the recognition of pathogen-associated molecular patterns. Single nucleotide polymorphisms (SNPs) within TLRs have a potential impact on the alteration of susceptibility or resistance to inflammatory diseases. This...
