Background: Monoclonal antibodies have been employed extensively for the identification of Leishmania species, development of diagnostic tests and in the characterization of defined leishmanial antigens. Objectives: Identification and characterization of  Leishmania spp. directly from cutaneous lesions of infected individuals. Methods: An immunoperoxidase test (Avidin-Biotin technique) using mo...

Objectives – After lab you will be able to • describe the relationship between food availability and single-species population density (carrying capacity) • explain how competition influences the carrying capacity of individual species where they cooccur and compete • explain why predation is important for maintaining species diversity • realize the difficulty of predicting ecological outcomes ...

Winter wheat is a suitable crop to be ensiled for animal feed and China has the largest planting area of this crop in the world. During the ensiling process, lactic acid bacteria (LAB) play the most important role in the fermentation. We investigated the natural population of LAB in whole-crop wheat (WCW) and examined the quality of whole-crop wheat silage (WCWS) with and without LAB inoculants...

in this paper, the metazoan parasite community system of capoeta damascina in the tigris basin (mesopotamian region) in the middle-east is presented. overall, 54 species have been identified. between 2005 and 2008, iranian surveys of capoeta damascina found a total of 47 metazoan parasites species, most identified to species level. in addition, 6 parasite species from iraq and 1 species from oc...

A total of eight from thirty LAB isolated from fruits samples showed clear zone on modified de Man, Rogosa and Sharp (MRS)-CaCO3 agar, catalase negative and Gram positive were considered as LAB. From six out of eight isolates was observed good proteolytic activity when tested on skim milk agar. The isolates were identified with species of morphology and biochemical analysis using API 50 CHL kit...

Lactic acid bacteria (LAB) exert antagonistic activities against diverse microorganisms, including pathogens. In this work, we aimed to investigate the ability of LAB strains isolated from food produce biofilms and inhibit growth surface colonization Enterohaemorrhagic Escherichia coli (EHEC) O157:H7 at 10°C. The 100 EHEC NCTC12900 was evaluated in agar diffusion assays. Thirty-seven showed str...

Background: Identification of the dominant lactic acid bacteria involved in the production of traditional cheese in Semnan could be the initiative to protect national genetic resources and produce industrial cheese with desirable texture and organoleptic characteristics similar to traditional cheeses. The present study aimed to determine the biochemical, physiological, and phenotypic properties...
