Scanning electron and light microscopy of selected avian strains of Mycoplasma iowae. 1983

J E Gallagher, and K R Rhoades

The morphology of six strains of Mycoplasma iowae was studied at various stages of growth by scanning electron and light microscopy. The six strains, which formerly represented avian mycoplasmal serotypes I, J, K, N, Q, and R, produced filaments and branching filaments, sometimes with centrally or terminally located bulbous swellings. During cell division, the filaments appeared to develop into chains of coccal, coccobacillary, and elongated cells. Mycoplasmas that appeared as chains of cocci under light microscopy were often observed as coccobacillary or fusiform when viewed with scanning electron microscopy. The morphology of single or paired cells of all strains included cocci, rods, coccobacilli, and pleomorphic forms. Fusiform and teardrop-shaped cells with bleb-like structures were also observed. Some cells of all strains deteriorated by the latter growth stages, forming clumps of flattened irregular-shaped cells, sometimes intertwined with fragmented filaments. The formation of filaments, branching filaments, and the other cell morphology indicated that the six strains of M. iowae were similar in morphology and growth characteristics.

UI	MeSH Term	Description	Entries
D008855	Microscopy, Electron, Scanning	Microscopy in which the object is examined directly by an electron beam scanning the specimen point-by-point. The image is constructed by detecting the products of specimen interactions that are projected above the plane of the sample, such as backscattered electrons. Although SCANNING TRANSMISSION ELECTRON MICROSCOPY also scans the specimen point by point with the electron beam, the image is constructed by detecting the electrons, or their interaction products that are transmitted through the sample plane, so that is a form of TRANSMISSION ELECTRON MICROSCOPY.

D009174	Mycoplasma	A genus of gram-negative, mostly facultatively anaerobic bacteria in the family MYCOPLASMATACEAE. The cells are bounded by a PLASMA MEMBRANE and lack a true CELL WALL. Its organisms are pathogens found on the MUCOUS MEMBRANES of humans, ANIMALS, and BIRDS.

D002645	Chickens	Common name for the species Gallus gallus, the domestic fowl, in the family Phasianidae, order GALLIFORMES. It is descended from the red jungle fowl of SOUTHEAST ASIA.	Gallus gallus,Gallus domesticus,Gallus gallus domesticus,Chicken
D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D013045	Species Specificity	The restriction of a characteristic behavior, anatomical structure or physical system, such as immune response; metabolic response, or gene or gene variant to the members of one species. It refers to that property which differentiates one species from another but it is also used for phylogenetic levels higher or lower than the species.

D014422	Turkeys	Large woodland game BIRDS in the subfamily Meleagridinae, family Phasianidae, order GALLIFORMES. Formerly they were considered a distinct family, Melegrididae.	Meleagridinae,Meleagrididae
