The wilayets concerned are those of Mascara, Relizane, Tiaret and Tissemsilt. The techniques of the buffered antigen test (EAT), the complement fixation (CF) and indirect enzyme immunoassay (i-ELISA) are used. A number 744 of dairy cows is affected by these different tests. In the wilaya of Mascara, a total of 418 cows, only two cases were positive by using the EAT and 99 test cases using ELISA. At Tiaret, the total number of dairy cows monitored is 156. Only one case is held by EAT positive, but the use of immunoassay test showed 14. A similar observation was made for the 170 cows tested in Relizane province. In this region, eight cases were positive using ELISA. The other tests were negative. About five cows on Tissemsilet, controlled only one positive case is obtained by ELISA. The results obtained using the three tests show the performance of the immunoassay has identified many cases of brucellosis found negative in the test use of the buffered antigen test and the fixing of supplement. The ELISA has better sensitivity because among the 744 sera tested only 03 sera were found positive using tests of the EAT and FC, but 112 cases were detected positive by ELISA. The animals that reacted positively to the ELISA have not done any testing EAT while all animals tested positively are for the ELISA. This zoonosis exists in western Algeria with a prevalence of 15.05% revealed by use of ELISA test with sensitivity and performances are recognized.

Abstract Brucellosis, the most common bacterial zoonosis in both human and animals, has a widespread geographic distribution. To prevent this disease in cattle (in the western region of Algeria) and to preserve the quality of the milk and other derivatives, we screened for detecting the presence of serum antibodies (against Brucella) by different immunochemical tests. The wilayets (state) concerned were from Mascara, Relizane, Tiaret and Tissemsilt. The study involved the involvement of techniques such as the buffered antigen test (EAT), indirect enzyme immunoassay (i-ELISA) and the complement fixation (CF).

The International Committee in Algeria
INTERNATIONAL COMMITTEE OF THE RED CROSS THE INTERNATIONAL COMMITTEE IN ALGERIA Work in the medical field The ICRC actively developed its relief operation in Algeria in June. Acute medical and sanitary problems are facing its delegates, especially in Oran. As reported earlier the ICRC has sent a medical team of three to the Moslem city of Oran, where medicines, surgical instruments and equipment, and dietetic milk for new-born children, are most urgently needed. Following urgent requests by its dele- gates on the spot the ICRC immediately despatched by air two tons of dietetic powdered milk: Two further shipments were also sent by the French Red Cross, one of eight crates of sugared concen- trated milk, the other of one and a half tons of standardised milk. Dr. J.-L. de Chastonay, medical adviser of the ICRC delegation in Algeria, sent a first shipment of medicines to Oran. This was shortly followed by a large quantity of medicines sent from Paris on June 5th by the French Red Cross including antibiotics, ophtal- mic ointment and special medicines. Others shipments are now on their way to Oran. On June 14th, a special plane took off from Geneva for Algiers with a cargo of medicines and medical equipment valued at 40,000 Swiss Francs. From Geneva, the ICRC has now sent to Algiers four different shipments of medicines, vaccines and equipment for blood trans- fusion, totalling 1,400 kilograms (about 3,000 lb.) and valued at 45,000 Swiss francs. It will be recalled that four doctors and a male nurse are now engaged in the ICRC relief action in Algeria : they are Dr.

Genetic Resources of Carob Tree (Ceratonia Siliqua L.) in Algeria: Insight from Pod and Seed Morphology

Laboratoire de production, amélioration et protection des végétaux et des denrées alimentaires, Department of Agronomic Sciences, Faculty of Biological and Agronomic Sciences, Mouloud MAMMERI University, Tizi-Ouzou, 15000, Algeria Reçu le 08/07/2019, Révisé le 14/12/2019, Accepté le 23/12/2019 Abstract Description of the subject. In Algeria, the carob tree extends over a large area from East to West. Yet data on the pattern of morphological variation of its pods and seeds across such area are lacking, despite the usefulness of a good understanding of intraspecific variation of such traits for domestication, conservation and sustainable management purposes. Objective: The present study aims at describing morphological variation in pod and seed traits of such populations and addresses the following questions: (a) what is the level of variation within and between wild carob populations; (b) and how is such variation spatially distributed? Methods: 07 wild carob populations of northern Algeria were investigated for pod and seed morphology. Results: Significant differences between provenances were observed for all quantitative traits. Slight differences between trees were also observed. Pod shape and seed surface were the most uniform traits among provenances. Within-provenance, the proportion of polymorphic trees for a given qualitative trait was variable.

Land Suitability Evaluation for Winter Wheat in Tiaret Region (Algeria)

Abstract A landresources analysis was canied out in theTiaret Region, one of themost important cereal growing areas (especially durum wheat) of Algeria. The principal ahn of the work wasthe assessment of land suitabilityfor rainfed winter wheat. The primary source of information was Laldsat TM imagery, which was utilized to obtain a Land Unit map (scale 1:200,000). After preliminary image interpretation. the whole area was surveyed in a multidisciplinary and integrated way, following a holistic approach to the analysis of land. AU data were processed integrating different hardware/software resources. The land suitability assessment has been conducted according tothe Guidelines for Land Evaluation for Rainfed Agriculture (FAO,1983). Most land units showed physical limitations, in terms of climate, soil, topography and erosion risks. Only about2% of the entire study areawas evaluated "vely suitable", mainly in the northem and central alluvial plains, while56% was evaluated 'hot suitable", because of climate and/or mo1phology. Résumé Cet article va présenter une étude intégrée des ressources naturelles réalisée dans la région de Tiaret qui est l'une zone des plus importantes pourla culture des céréales (blé dur en particulier) en Algérie. L'objet principalde ce travail était l'évaluation de l'aptitude des terres pourla culture du blé dur sans irrigation. La première source d'information était constituée par des images LandsatTM qui ont été utilisées pour obtenir une cartedes Unités de Terres(échelle 1/200 000).
