Diffusion tensor imaging tractography in the one-humped camel () brain.

Introduction: Tractography is a technique used to trace the pathways of the brain using noninvasive diffusion tensor imaging (DTI) data. It is becoming increasingly popular for investigating the brains of domestic mammals and other animals with myelinated fibers but the principle of DTI can also apply for those with unmyelinated fibers. In the case of camels, DTI tractography is a promising method for enhancing current knowledge of the brain's structural connectivity and identifying white-matter tract changes potentially linked to neurodegenerative pathologies.

First molecular detection of Neospora caninum from naturally infected slaughtered camels in Tunisia.

Background: Neospora caninum has been documented to infect most domestic wildlife but is known to primarily infect dogs and cattle and is considered an important cause of abortion in camels.

Objective: The aim of this study was to estimate the molecular detection of Neospora caninum in tissues of naturally infected camelids.

Methods: Brain, tongue (bottom and tip) and masseter muscles from 35 slaughtered camelids from Tataouine and Médenine regions were collected (n = 140 samples).

Newly detected mutations in the Meq oncogene and molecular pathotyping of very virulent Marek's disease herpesvirus in Tunisia.

Marek's disease (MD) is a contagious avian viral disease that is responsible for large economic losses to farmers. The disease is caused by Marek's disease virus (species Gallid alphaherpesvirus 2), which causes neurological lesions, immune suppression, and tumor proliferation of lymphoid cells that invade a large number of organs and tissues. Despite widespread vaccination, Marek's disease virus (MDV), has shown a continuous increase in its virulence and has acquired the ability to overcome immune responses induced by vaccines.

Preliminary safety assessment of Yarrowia lipolytica extracellular lipase: results of acute and 28-day repeated dose oral toxicity studies in rats.

Interest in extracellular lipase sourced from the non conventional yeast Yarrowia lipolytica has increased over the last decade. The enzyme was recently suggested as a good candidate for pancreatic exocrine insufficiency treatment. However, there is still a lack of oral safety evaluation data.
