No case of autochthonous malaria has been detected in Morocco since 2004. This achievement is due to a national strategy to combat the disease by appropriate and well-organized disease detection and treatment, as well as control of the mosquito vector of the disease, the female Anopheles mosquito. Nonetheless, imported malaria cases have been increasing (75 in 2007), due to the rise in international travel and migration from countries where the disease is endemic.

Article Synopsis
  • The study analyzed 219 Mycobacterium tuberculosis complex (MTBC) isolates from TB patients in Morocco using spoligotyping and 12-loci MIRU-VNTR methods to identify dominant genotypes.
  • Spoligotyping revealed 39 unique patterns, with SIT42 being the most common, while 12-Loci MIRU typing identified 25 clusters and noted a recent transmission rate of 22.3%.
  • Findings illustrate that TB transmission in Morocco is primarily through modern MTBC lineages, indicating a diverse bacterial population and emphasizing the effectiveness of these genetic typing methods for identifying mixed infections.

Introduction: Both monocyte chemoattractant protein-1 (MCP-1), also designated officially as chemokine (C-C motif) ligand 2 (CCL2), and interleukin-12 p40 (IL-12 p40) molecules, encoded by polymorphic genes, are central components of the immune response to infection by Mycobacterium tuberculosis (Mtb). Their genetic diversity has previously been associated with the outcome of tuberculosis (TB) infection. We investigated whether the MCP-1 -2518 A/G and the IL-12B (p40) +1188 A/C polymorphisms influence susceptibility to or resistance against pulmonary tuberculosis (PTB) in a Moroccan population group.

Molsidomine, a long-acting vasodilator mainly used as an antianginal agent, was reported to decrease the portohepatic venous pressure gradient in patients with alcoholic cirrhosis. This study investigated the effects of linsidomine, the active metabolite of molsidomine, on systemic and splanchnic hemodynamics in rats with CCl4-induced cirrhosis using the microsphere technique. Compared with placebo-treated rats, linsidomine-treated animals were found to have a significant decrease in portal venous pressure (-18%, p less than 0.
