    Aspects of the ontogenesis of the avian columella auris

    Observations on embryological material from Spheniscus demersus, Acridotheres tristis, Geopelia cuneata and Gallus domesticus strongly suggest that the avian stapes represents part of an infrapharyngohyal while the rest of the pharyngohyal material (supra- plus infrapharyngohyal) together with the epihyal and a secondary laterohyal component form the extracolumella. The latter structure bears three so-called processes: the supracolumellar arcade or process (de Beer's lateral prong) whose inner limb is derived from the suprapharyngohyal and the outer limb (comprising at least part of the intercalary) from the laterohyal blasteme; the tympanic process (extracolumellar process) also derived from laterohyal blasteme; and the infracolumellar process (formed by the distal tip of the epihyal and a composite interhyal) which is continuous with the ceratohyal in most birds. Our investigation suggests that the supposed great variation in the development of the columella among birds is a fallacy.Waarnemings op embriologiese preparate van Spheniscus demersus, Acridotheres tristis, Geopelia cuneata en Gallus domesticus dui sterk daarop dat die stapes by voSIs deel van 'n infrafaringohiale verteenwoordig terwyl die res van die faringohiale materiaal (supra- plus infrafaringohiale) saam met die epihihiale en 'n sekonddre laterohiale komponent die ekstrakolumella vorm. Laasgenoemde struktuur dra drie sogenaamde uitsteeksels: die suprakolumellaar-uitsteeksel of -arkade (‘lateral prong’ van de Beer) waarvan die ‘binnebeen’ van die suprafaringohiale afkomstig is en die ‘buitebeen’ (wat minstens 'n deel van die interkalare insluit) deur die laterohiale blasteem bygedra word; die timpaniese uitsteeksel of ekstrakolumellaar-uitsteeksel wat ook van die laterohiale blasteem afkomstig is; en die infrakolumellaar-uitsteeksel (gevorm deur die distale punt van die epihiale enn saamgestelde interhiale) wat by meeste vo荤is aaneenlopend met die keratohiale voorkom. Ons ondersoek dui daarop dat die vermeende groot variasie wat ten opsigte van die ontwikkeling van die kolumella by vofils sou bestaan, 'n dwaling is

    The morphogenesis of the avian Columella auris with special reference to Struthio camelus

    Get PDF
    The columella auris of the ostrich is derived as in the crocodile from three sources; the two upper segments of the hyoid arch (pharyngohyal and epihyal) and a laterohyal component. The latter contributes the homologue of the crocodilian suprastapedial (or lacertilian intercalary) as well as the tympanic process and the material of the lateral limb (which is not lacking as stated in the literature) of the lateral prong (supracolumellar arcade). Conditions in Struthio camelus confirm the views expressed by the authors in their paper on Crocodilus niloticus regarding the homologies of the columellar processes. The avian infracolumellar process represents the crocodilian infrastapedial plus the interhyal which in addition to primary arch material, includes a secondary subepidermal part. The ceratohyal (usually called stylohyal in the literature) remains attached to the columella through the infracolumellar process

    The Recent Cholera Outbreak in the South Mrican Gold Mining Industry

    Get PDF
    A large-scale cholera surveillance programme was introduced in South Africa in November 1973 as a result of the progressive southward spread of cholera in Africa. Moore's technique for the isolation of Salmonella paratyphi was modified for cholera detection. The method proved to be very sensitive and it was possible to detect Vibrio cholerae in main sewer lines after its casual and transient introduction by an unidentified carrier. Transmission occurred in the acc!im<:tisation centre, probably through the drinking of water contaminated after it had been drawn from the tap. Faecal contamination of the environment was demonstrated, and V. cho/erae was isolated from the floor, onto which it had been disseminated from the perianal region by means of profuse perspiration. Perpetuation of cholera was probably aided by a faecally contaminated air-humidifying water reservoir, the water of which experimentally allows survival and multiplication of V. cholerae for a week and longer. Prophylactic treatment of selected high-risk groups of people was administered in the form of doxycycline, which appeared to result in rapid termination of the epidemic. Mass vaccination of all mine personnel (20 000) was carried out to reduce the incidence of clinical cholera and the bacterial load
