Biologie Résumé :
This work represents a first study of the biodiversity of the actinomycetes inhabitants three Sebkhas protected by the Ramsar-Algeria convention. The physicochemical analyzes of the soil samples revealed extremely high salinities, basic or very basic pH, low percentages of moisture, moderate or very high percentages of organic matter. These results also showed that samples of sebkha Annk Djemel belong to the ""clay"" and ""Clay loam"" classes, samples of sebkha Guellif belong to the ""clay loam"" and ""sandy-clay loam"" classes and samples of sebkha Et Taref belong to the ""clay"" class. An isolation of actinomycetes from the soil has been achieved by the use of conventional methods and / or Culturomics. The enumeration results revealed that the number of actinomycetes could reach to
2.105 CFU/g of soil. Based on the enumeration results, a statistical analysis, carried out by the application of non-parametric tests of Kruskal-Wallis and Mann-Whitney, revealed that culture media relatively poor in nutrients and the concentration 5% of NaCl are the most favorable in the isolation of actinomycetes. The competitive effect of bacterial and fungal flora has also been highlighted. Following the isolation protocols adopted, we were able to purify and store a total of 204 isolates, all Gram (+), of which 108 isolates were derived from conventional isolation techniques and 96 isolates were obtained by the Culturomics method. Identification by the MALDITOF MS and sequencing of the 16S rDNA methods allowed us to identify a new species that we named Streptomyces massilialgeriensis sp. nov. and to assign certain other isolates to the genera Streptomyces, Nocardiopsis and Actinomyces. Other isolates have been identified as Bacillus, Virgibacillus, Gracilibacillus, Staphylococcus, Flavonifactor and Halobacillus. The activity test, carried out by the agar plug diffusion method, of 13 selected isolates belonging to the genera Streptomyces and Nocardiopsis against multidrug-resistant bacteria reveal interesting zones of inhibition of the isolate S20 against K. pneumoniae CSUR P1596 (coli R), E. coli CSUR P4969 (coli R, HLP), E. coli CSUR P5139 (carba R) and P. mirabilis CSUR P2049 (oxa-48), and isolate S112
against S. aureus CSUR P1943 (MRSA, KTG, inducible MLSB), E. coli CSUR P4969 (coli R, HLP) and P. mirabilis CSUR P2049 (oxa-48).

BiologieTags : Biologie Animale:Biodiversité et Ecologie des Arthropodes Biodiversité faunistique Collemboles Nord-Est algérien Biodiversity Faunistic Springtails North-eastern Algeria التنوع الحيوي الحيوانية شمال شرق الجزائر Index. décimale : 570 Sciences de la vie. Biologie Résumé :
The prospection of eight (08) localities of the North-East of Algeria belonging to three bioclimatic stages allows us to carry out a series of samplings in the edaphic environments. Samples analyzed at the laboratory of Biosystematics and arthropods ecology.The fauna encountered is composed of 89 species belonging to the four orders of known Collembola, to 17 families and 51 genera. The predominance of the Poduromorpha order with 43 species constitutes a remarkable character of this fauna. 24 species are reported here for the first time in Algeria including Isotomurus sp., Proisotoma sp. and Pseudosinella sp. 1, all three harvested at Collo, are new to Science and are being described.
Among the eight localities surveyed, it is from the Collo forest that most of the species harvested and identified are found, ie 72 species. The richness of the Neanuridae massif is much greater than that of most other Mediterranean regions (excluding Corsica) sampled significantly. Diversity indices indicate that Oued Z'hor is the richest station among the four stations surveyed at Collo. Another major interest of this faunistic study is the discovery of biogeographically unexpected taxa, in particular Sensillanura austriaca with its unusual ""Collo - Northern Alps"" disjunction model. A common species in our samples that can be new has been described and drawn. This description revealed that the species may be related to the species Heteromurus tetrophthalmus Börner, 1903 of Sicily, insufficiently described and considered for more than 30 years as a synonym of H. nitidus Templeton, 1836. Today, this work makes the Collo Massif one of the richest sites in Algeria for the
diversity of its fauna. It also illustrates the extent of geographical gaps in the knowledge of this Algerian fauna.

,Index. décimale : 570 Sciences de la vie. Biologie Résumé : With an aim of improving our knowledge on the biodiversity of the phlebotomine sandflies and of culicidae, we carried out a series of sampling, in various biotopes and larval lodgings in the area of Skikda. Different technicals were employed: luminous traps adhesive and traps for the capture of the phlebotomine sandfies, the method of «Dipping" blow of ladle for the taking away of the culicidae. During one period of study going May until May at September 2005, the faunistic inventory of the species of phlebotomine sandfies and their distribution at various altitudes in 8 sites of trappings led to the census of 5 species appears on the level of 2 kinds Phlebotomus and Sergentomyia this last primarily represented by the species Sergentomyia minuta which dominates very largely in the whole of the captures. In parallel we have constitutes, laying one 10 months period (December 2004 to September 2005), an inventory of Culicidae fauna in 10 larval lodgings distributed between three stations, which is completed by the determination of 30 species of Culicidae pertaining to 4 kinds, Culex, Aedes, Anopheles and Culiseta. The Culex kind is represented best by far particularly with the species Culex pipiens, it is followed Aedes kind that the presence is in relation to the type of prospected lodging. In order to examine the relationship between the structure of the biotopes and the larval lodgings and the organization of the studied populations, several ecological in dications of structures and compositions as well as a statistical survey composed of an analysis of the variance and an analysis in main components have been used.
