Two main threads in the history of bacteriology: 1) the natural history of bacteria and 2) the contagious nature of infectious diseases, were united in the latter half of the 19th century. During that period many of the bacteria that cause human disease were identified and characterized. 2. Individual bacteria were first observed microscopically by Antony van Leeuwenhoek at the end of the 17th
Cultural Characteristics: ADVERTISEMENTS: The growth requirement and the appearance of colonies on media to the naked eye are further criteria to assist the identification of bacteria.
Characteristics of the organism that classifies its kingdom: cell type, body form, cell wall composi-tion, mode of nutrition, nervous system, and lo- comotion. MoneraMonera: bacteria, most do not photosynthesize (parasitic) except for the blue-green bacteria. ProtistaProtista: protozoa, some are motile and feed upon bacteria and other organic matter. Algae are part of this kingdom. Algae

SUMMARY Methods were described for cultural counts and the isolation and determina- tion of some characteristics of some of the more numerous groups of bacteria in the rumen of cows. Samples of tureen contents were diluted in an anaerobic dilution solution, mixed in a Waring blendor to disperse the bacteria, and cultured in an anaerobic agar culture medium containing minerals, rumen fluid
bacteria can produce very different colonies. In the accompanying picture of a mixed culture, an agar plate that has been exposed to the air and many different colony morphologies can be identified.
MEA does not produce colonies with differential characteristics. Colonies of V. choleraeon NEA are 2 to 4 mm in diameter after overnight incubation and are smooth, opaque, and cream colored. When viewed with oblique light with 10X to 20X magnification, colonies may appear finely granular and iridescent with a greenish bronze sheen. The oxidase test, string test and screening with antisera may
Cultural characteristics of actinobacteria refer to the growth characteristics and morphology in various kinds of culture media. Pure culture should be taken before morphological observation. The pure culture of actinobacteria can be obtained through the use of spread plates, streak plates, or pour plates and are required for the careful study of an individual microbial species

A colony’s characteristics (shape, size, pigmentation, etc.) are termed the colony morphology. Colony morphology is the way scientists identify bacteria. In fact, a book called Bergey’s Manual of Determinative Bacteriology (commonly termed Bergey’s Manual) describes most bacterial species identified by scientists so far. This manual provides descriptions for the colony morphologies of

THE IDENTIFICATION OF BACTERIAL ISOLATES WHAT IS MEANT BY IDENTIFICATION? The taxonomy of bacteria (or of any other group of organisms) consists of three interrelated areas. The task of arranging organisms into related groups is called classification. Nomenclature refers to the assignment of names to these groups, guided by a set of rules. Identification is the process of determining to …
The morphological characteristics of the intestinal symbiotic microflora of pike include the formation of the capsule, pseudovacuoles, and spheroplastic forms of cells. The bacteria that were found can produce hydrolytic enzymes and possess persistence properties. The morphophysiological features that were found contribute to the adaptation of bacteria to environmental conditions and indicate
