Mycoplasma gallisepticum is an economically important pathogen of poultry worldwide. Yet the characteri­ sation of M. gallisepticum field strains present in southern Africa has not previously been reported. We characterised various M. gallisepticum genotypes within the region and highlight the unique differences between two genotypes found in South Africa and Zimbabwe. PCR targeting a partial r...

In this study, we report the development and validation of a real-time polymerase chain reaction (PCR) assay using a Taqman-labeled probe for the detection of Mycoplasma gallisepticum (MGLP assay). The MGLP assay was highly specific with a detection limit of 25 template copies per reaction and a quantification limit of 100 template copies per reaction. Validation of the assay was completed with...

Mycoplasma gallisepticum, the most pathogenic mycoplasma in poultry, is able to glide over solid surfaces. Although this gliding motility was first observed in 1968, no specific protein has yet been shown to be involved in gliding. We examined M. gallisepticum strains and clonal variants for motility and found that the cytadherence proteins GapA and CrmA were required for gliding. Loss of GapA ...

Mycoplasma gallisepticum (MG) and Mycoplasma synoviae (MS) are the most pathogenic and economically important mycoplasma pathogens that infect chickens. The development of rapid and innovative molecular diagnostic techniques is of pivotal importance for their effective control. The aim of the present study was to develop a novel duplex TaqMan real-time PCR assay for the simultaneous detection o...

Mycoplasmas are very small bacteria lacking cell walls that belong to various genera within the class Mollicutes, and also the smallest organisms that can live independently. They are able to cause serious and chronic disease because of some unique characteristics. Mycoplasma gallisepticum (MG) is an important avian pathogen causing significant economical losses within the poultry industry. The...

Carbon-based compounds exhibit unexpected structures and electronic behavior at high pressure arising from various bonding features of carbon (e.g., sp, sp(2) and sp(3) C-C bonds). Here we report evolution of crystal structures of MgC2 in a wide pressure range of 0-200 GPa as predicted through ab-initio calculations in combination with an unbiased swarm structure search. Three pressure-induced ...

Poultry red mite (PRM, Dermanyssus gallinae) is a blood-sucking ectoparasite as well as a possible vector of several avian pathogens. In this study, to define the role of PRM in the prevalence of avian infectious agents, we used polymerase chain reaction (PCR) to check for the presence of seven pathogens: Avipox virus (APV), Fowl Adenovirus (FAdV), Marek's disease virus (MDV), Erysipelothrix rh...

Mycoplasma gallisepticum (MG) is economically important pathogen of poultry causes airsacculitis and frequently infraorbital sinusitis in turkeys. Infections may remain without clinical signs, but they can make birds susceptible to secondary infections. This study was carried out for molecular detection and phylogenetic analysis of MG infections in commercial and backyard turkey flocks in some ...

Antifriction self-lubricating glass composite coatings of the Sic-Ni-Cu-Al-Si-C type additionally contain an aluminoborosilicate phase and structurally free MgC2, which forms α-graphite during thermolysis, synergistic effect causes modification friction surface due to formation antifriction layer. The influence structural components coating on their contribution properties is considered. It was...

Abstract The poultry sector in Pakistan is contributing mainly bridging gap between demand and supply for protein. Mycoplasma gallisepticum an emerging bacterium causing serious problems industry of Pakistan. A cross-sectional study was conducted to evaluate the M. load populated regions Total 600 serum swab samples were collected, 200 from each broiler, layers breeders Rawalpindi Abbottabad di...
