Effects of Pollen Deprivation in Groups of Tellian (Apis mellifera intermissa) and Saharan (Apis mellifera sahariensis) Honey Bees under Controlled Conditions.

Worldwide, honey bees are increasingly faced with periods of pollen scarcity, which can lead to nutritional deficiencies, especially of proteins and amino acids. These are essential for the proper functioning of the single organism and the colony. To understand how bees react to protein deficiency, under controlled conditions, we studied the effect of pollen deficiency on the main physiological parameters in two subspecies endemic of Algeria, Apis mellifera intermissa and Apismellifera sahariensis. Emerging workers of both subspecies were reared with two diets: one was pollen-fed, whereas the …

Preferential damaging effects of limited magnesium bioavailability on photosystem I in Sulla carnosa plants.

Magnesium deficiency preferentially inhibits photosystem I rather than photosystem II in Sulla carnosa plants. The effects of magnesium (Mg(2+)) deficiency on growth, photosynthetic performance, pigment and polypeptide composition of chloroplast membranes were studied in the halophyte Sulla carnosa (Desf.), an annual legume endemic to Tunisia and Algeria. The results demonstrate a gradual decrease in biomass production with decreasing Mg(2+) availability in the growth medium. The increase of Mg(2+) deficiency was also associated with a decline of the net CO2 assimilation (Pn) in fully expanded…

Identifying Areas Suitable for the Occurrence of Rift Valley Fever in North Africa: Implications for Surveillance.

Rift Valley fever (RVF) is a vector-borne zoonotic disease that has caused widespread outbreaks throughout Africa and the Arabian Peninsula, with serious consequences for livestock-based economies and public health. Although there have never been any reports of RVF in Morocco, Algeria, Tunisia and Libya, it is a priority disease in the Maghreb, due to the threat of introduction of the virus through transboundary livestock movements or infected mosquito vectors. However, the implementation of surveillance activities and early warning contingency plans requires better knowledge of the epidemiolo…

Circulation of a Meaban-like virus in yellow-legged gulls and seabird ticks in the western Mediterranean basin.

In recent years, a number of zoonotic flaviviruses have emerged worldwide, and wild birds serve as their major reservoirs. Epidemiological surveys of bird populations at various geographical scales can clarify key aspects of the eco-epidemiology of these viruses. In this study, we aimed at exploring the presence of flaviviruses in the western Mediterranean by sampling breeding populations of the yellow-legged gull (Larus michahellis), a widely distributed, anthropophilic, and abundant seabird species. For 3 years, we sampled eggs from 19 breeding colonies in Spain, France, Algeria, and Tunisia…

[Treatment of homozygote beta thalassemia in Algiers. A 5-year follow-up of 66 patients].

During the years 1982-1987, 66 patients with homozygous beta-thalassaemia were treated at the blood transfusion centre of Algiers. The patients, aged from 1 to 23 years in 1982, came from 48 families, 30 of which were issued from consanguinous unions. The patients fell into three groups according to the early institution and quality of treatment (blood transfusions, antibiotic therapy, desferrioxamine given when available). The beneficial clinical effects observed (satisfactory growth and development, reduction of splenomegaly and hypersplenism, attenuation of craniofacial malformations, perfo

Immunological surveys of diphtheric antitoxic antibodies in some African and Asian countries.

Immunological surveys of diphtheric antitoxic antibodies confirmed the existence of a high circulation of Corynebacterium diphtheriae in some African and Asian countries. The high immunity level in early childhood confirms the well known fact that other forms of diphtheria, in particular the cutaneous forms, participate in the formation of antitoxic antibodies. Immunological surveys can determine relatively exactly the extent of risk of infection in the separate age groups and thus delimit the range of the planned vaccination campaigns. Exact determination of the age groups eligible for vaccin
