Genotypic interactions among competing strains and species of Drosophila.
VIDENCE is accumulating to support the observation that the fitness of a E particular genotype in a given environment may be improved or impaired by the presence in that same environment of conspecific carriers of other genotypes. This has been shown in Drosophila pseudoobscura by LEVENE, PAVLOVSKY and DOBZ,HANSKY (1954), and BEARDMORE (1963) ; in D. melanogaster by LEWONTIN (1955) ; in D. busc...
متن کاملEnterotoxigenicity of Salmonella Gallinarum strains isolated from poultry
Twenty Salmonella Gallinarum strains isolated from poultry were tested for Enterotoxigenicity activity using rabbit and chicken ligated intestine loop technique and the rabbit vascular permeability factor activity test. One ml of cell-free filtrate (CFF) of each isolate was injected into chicken ligated loops and rabbit ligated loops, one ml of whole cell culture(WCC) of each isolate was inject...
متن کاملGenotypic and phenotypic heterogeneity in familial microcoria.
AIMS To describe the clinical features and genetic findings in two families presenting with microcoria inherited as an autosomal dominant trait. METHODS Both affected and unaffected members of two families displaying familial microcoria were examined. Flash photography or infrared pupillography were used to assess pupils, and a full ophthalmic examination including visual acuity and field tes...
متن کاملGenotypic and phenotypic heterogeneity among Mycobacterium tuberculosis isolates from pulmonary tuberculosis patients.
Although the heterogeneity of Mycobacterium tuberculosis populations and the existence of mixed infections are now generally accepted, systematic studies on their relative importance are rare. In the present study, 10 individual colonies of each M. tuberculosis isolate (primary isolate) from 97 tuberculosis patients in a primarily human immunodeficiency virus-negative population were screened f...
متن کاملPhenotypic and genotypic heterogeneity among cultivable pathogen-related oral spirochetes and Treponema vincentii.
Recent findings challenge the assumption that pathogen-related oral spirochetes (PROS) are related to Treponema pallidum. Treponema vincentii, grown in OMIZ-Pat media, cross-reacted with monoclonal antibody H9-2 against T. pallidum, and cultivable PROS had 16S rRNA gene sequences similar to those of T. vincentii (C.-B. Choi, C. Wyss, and U. B. Göbel. J. Clin. Microbiol. 34:1922-1925, 1996). Aim...
