Linkage and segregation of a mating type specific phage and resistance characters in nocardial recombinants.
ECOMBINATION of auxotrophic and inhibitor resistant characters from crosses of Nocardia canicruria and Nocardia erythropolis have been previously reported (ADAMS and BRADLEY 1963; ADAMS 1964; BROWNELL and ADAMS 1967). Substrains derived from N . canicruria were observed to mate only with substrains derived from N . erythropolis while substrains of homologous origin were incompatible. From these...
متن کاملThe Nature and Inheritance of Mating Types in Euplotes Patella.
N A previous paper (KIMBALL 1939b), the occurrence of six mating I types in the ciliate protozoan Euplotes patella was reported. These have since been designated by the Roman numerals I to VI. Considerable information which has now been gained about the inheritance and nature of the action of the mating types in this organism will be set forth in the present paper. The investigations presented ...
متن کاملDetermination and inheritance of mating type in Paramecium caudatum.
M A T I N G type determination and inheritance in Paramecium caudatum has been reported only for syngen 12 (HIWATASHI 1958). Inheritance was usually synclonal, i.e. the two clones derived from the two members of a conjugating pair are identical in mating type expression, indicating direct genic control of mating type. However the breeding analysis was incomplete and some of the observations, as...
متن کاملEndobronchial nocardial infection.
The rare presentation of nocardial infection as an endobronchial "tumour" is reported. Haematogenous dissemination occurred after fibreoptic bronchoscopy and biopsy, a phenomenon not previously described in nocardial infections. This case highlights the difficulties in diagnosing pulmonary nocardial infection and the potential for invasive procedures to disseminate the disease.
متن کاملNocardial brain abscess in an immunocompetent host.
Nocardial infection of the central nervous system is rare and usually manifests as brain abscess. Here we describe an elderly gentleman who presented with signs and symptoms of an intracranial mass lesion localising to the frontal lobe. Clinical examination and CT scan suggested neoplasia as the probable diagnosis. A biloculated abscess was seen at surgery. Aspiration of the contents and examin...
