Article Synopsis
  • The study focused on analyzing the molecular and genetic profiles of Theileria annulata, a parasite causing tropical theileriosis in cattle, and its tick vector Hyalomma scupense in Algeria.
  • Researchers collected 40 H. scupense ticks in Medea, finding 5 that tested positive for Theileria spp., which were then further analyzed for genetic variations.
  • The findings included the discovery of two new haplotypes for the tick's 12S rRNA and one new haplotype for COX1, along with a previously identified T. annulata haplotype, enhancing our understanding of the genetic diversity of both the parasite and its vector in the region.

COVID-19 caused an increase in the demand for medications, which led to an increase in pharmaceutical waste and there is no doubt that this contributes to environmental pollution. Hence, it became necessary to search for how to protect and improve the environment by encouraging the behavior of medication waste reduction. Accordingly, this study aims to investigate the factors affecting intentions to reduce medication waste.

Antibiotic susceptibility of Staphylococci isolated from bovine mastitis in Algeria.

J Adv Vet Anim Res

June 2019

Institute of Veterinary Sciences, Laboratory of Biotechnology Related to Animal Breeding, University Saad Dahleb, Blida, Algeria.

Objective: This work aimed to determine the resistance and/or the susceptibility to antibiotics of staphylococci isolated from cattle with mastitis in the North of Algeria.

Materials And Methods: The disk diffusion method was carried out to reveal the antibiotic resistance in accordance to the National Committee for Clinical Laboratory Standards guidelines in the Mueller-Hinton agar.

Results: Coagulase-negative (CNS) isolates showed more resistance to Cefoxitin, Amoxicillin + Clavulanic Acid, Vancomycin, Trimethoprime Sulfamethoxazole, Clindamycine, Neomycin, and Erythromycin than Coagulase-positive (CPS).

Seroprevalence of anti- antibodies in cows of North-Eastern Algeria.

Vet World

June 2019

Veterinary Institute, University Saad Dahleb, Route de Soumaa, BP 270, Blida 9000, Algeria.

Aim: The present cross-sectional study aimed at assessing the seroprevalence of infection both at herd and within herd and at determining risk factors that are associated with its seropositivity.

Materials And Methods: A total of 90 cows distributed over seven herds located in two North-Eastern Algerian provinces were blood sampled in order to be tested for the presence of antibodies against using a commercially available enzyme-linked immunosorbent assay kit.

Results: The individual seroprevalence of was found to be 12.

This paper aims to outline a proposed knowledge base system (KBS) for the assessment of corrosive damage on metallic pipe conduits. KBS is developed by using two information sources available for assessing the corrosive damage of pipes which are mainly: expert knowledge and field data. In our knowledge, it's a new method that assists the engineer in his task for assessing the degree of damage on metallic pipes, yielding therefore to a rational evaluation of the corrosive damage (hence the ECOR system) on metallic structures of pipeline, and permits to assign the damage degree on the structure qualitatively while using a ladder of indications representing the severity of each damage type (pitting, crater, weight loss and crack), regarding the priority of either repairing or replacing the metal piece.

The latest studies in Algeria show that the frequency of type 1 diabetes (T1D) without complications is lower than that with complications and represents a significant burden in terms of cost and treatment. For this reason, we are interested in uncomplicated type1 diabetes and risk factors that are related to polymorphisms of antioxidant enzymes in order to prevent its complications. A total of 260 blood samples of young Algerian adults were examined.

February 2014

Laboratory of Chemistry of Natural Substances (EA 1069), University of Limoges, 123, avenue Albert-Thomas, 87060 Limoges cedex, France. Electronic address:

Aphis spiraecola and Aphis gossypii cause harmful damages on clementine tree orchards. Weekly surveys measured the abundance of aphids (larvae, winged and wingless adults) as well as of auxiliary insects and parameters of energy metabolism. Correlatively, soluble carbohydrates, total free amino acids, free proline and condensed tannins were quantified in control and infested leaves.

The aim of this work is to study the characteristics of the dromedary nervous lobe and determine how the seasons condition its organization. To this end, electron microscopy was performed and examined quantitatively on animals from winter and summer periods. The results show a higher number of cells in the nervous lobe in summer than in winter.
