Published: May 2014

Different strains of one genetic model species after another are turning out to have limited abilities to interbreed, as if they were on the way to becoming different species. Are model organisms aberrations, or are the first steps in speciation easier than they seem?

Background: Prolonged natural selection and artificial breeding have contributed to increased uniformity within the Tibetan sheep population, resulting in a reduction in genetic diversity and the establishment of selective signatures in the genome. This process has led to a loss of heterozygosity in specific genomic regions and the formation of Runs of Homozygosity (ROH). Current research on ROH predominantly focuses on inbreeding and the signals of selection; however, there is a paucity of investigation into the genetic load and selective pressures associated with ROH, both within these regions and beyond.

Ceftazidime-avibactam (CZA) is currently one of the last resorts used to treat infections caused by carbapenem-resistant Enterobacteriaceae and Pseudomonas aeruginosa. However, KPC variants have become the main mechanism mediating CZA resistance in KPC-producing gram-negative bacteria after increasing the application of CZA. Our previous study revealed that CZA-resistant KPC-33 had emerged in carbapenem-resistant P.

Foot-and-mouth disease virus (FMDV) is a highly contagious, economically important disease of livestock and wildlife species. Active monitoring and understanding the epidemiology of FMDV underpin the foundations of control programmes. In many endemic areas, however, veterinary resources are limited, resulting in a requirement for simple sampling techniques to increase and supplement surveillance efforts.

Background And Aim: Megaloblastic anemia (MA) is a rare pathology in childhood due, in the majority of cases, to a deficiency of folic acid and/or vitamin B12 (cobalamin). This study aims to determine the epidemiological, clinical, and paraclinical profiles of MA in children and to specify its etiologies, therapeutic modalities, and treatment responses.

Methods: This is a retrospective descriptive study of MA cases in children carried out in the General Pediatrics Department of the Hedi Chaker University Hospital of Sfax over a period of 42 years, from January 1979 to December 2021.
