How to use Bacteriology in a sentence
The bacteriology of the infective diseases (with bibliography) is fully given in the System of Medicine, edited by Clifford Allbutt, (2nd ed., London, 1907).
Pharmacology is a branch of biology; it is also closely connected with pathology and bacteriology, for certain drugs produce structural as well as functional changes in the tissues, and in germ diseases the peculiar symptoms are caused by foreign substances (toxins) formed by the infective organisms present in the body.
Of this method the rise and wonderful extension of the science of bacteriology also furnished no inconsiderable part.
As to such reforms in our conceptions of disease the advances of bacteriology profoundly contributed, so under the stress of consequent discoveries, almost prodigious in their extent and revolutionary effect, the conceptions of the etiology of disease underwent no less a transformation than the conceptions of disease itself.
A knowledge of the bacteriology of scrofulous affections of bone and joints, such as caries and gelatinous degeneration, has shown that they also are tubercular diseases - that is to say, diseases due to the presence locally of the tubercle bacillus.Advertisement
The ghastly roll of infantile mortality was quickly purged of its darkest features (Ballard and others); aided by bacteriology, sanitary measures attained some considerable degree of exactness; public medicine gained such an ascendancy that special training and diplomas were offered at universities; and in 1875 a consolidated act was passed for the United Kingdom establishing medical officers of health, and responsible lay sanitary authorities, with no inconsiderable powers of enforcing the means of public health in rural, urban, port and other jurisdictions, with summary methods of procedure.
This form of relationship is now known in other groups of plants (see Bacteriology and Fungi), but it was first discovered in the lichens.
With the Cyanophyceae must be included, as their nearest allies, the Bacteriaceae (see Bacteriology).
Toxins are also injected in order to stimulate the blood plasma to form antitoxins (see Bacteriology).
The discoveries made in pathological bacteriology, indeed, must be held to be among the most brilliant of the age.Advertisement
Again, besides giving us the clue to the nature of many diseases and to the continuity of many morbid series, by bacteriology certain diseases, such as actinomycosis, have been recognized for the first time.
As regards infections, it is not to be supposed that our knowledge of these maladies has been advanced by pathology and bacteriology only.
All these terms, including the usual one of bacteria, are unsatisfactory; for " bacterium," " bacillus " and " micrococcus " have narrow technical meanings, and the other terms are too vague to be scientific. The most satisfactory designation is that proposed by Nageli in 1857, namely " schizomycetes," and it is by this term that they are usually known among botanists; the less exact term, however, is also used and is retained in this article since the science is commonly known as " bacteriology."
Indeed, nothing marks the attitude of modern bacteriology more clearly than the increasing attention which is being paid to useful fermentations.
A branch of bacteriology which offers numerous problems of importance is that which deals with the organisms so common in milk, butter and cheese.Advertisement
These facts, and the further knowledge that many bacteria never observed as parasites, or as pathogenic forms, produce toxins or poisons as the result of their decompositions and fermentations of organic substances, have led to important results in the applications of bacteriology to medicine.
Research was also carried on and included bacteriology, histopathology, and, later, biochemistry.
The III incorporates multiple research groups with expertise in molecular bacteriology, virology, chemical biology, immunology and cancer immunity.
Trengove A. (1996) ' qualitative bacteriology and leg ulcer healing ' .
The report will be of interest to managers and staff in clinical bacteriology and serology laboratories.Advertisement
Investigations can be carried out by the bacteriology section of transfusion microbiology.
The phenomenon of nitrification (see BACTERIOLOGY, AGRICULTURE and MANURE), i.e.
For the growth of bacteria there must be a certain food supply, moisture, in most cases oxygen, and a certain minimum temperature (see Bacteriology).
Bacteria (see BACTERIOLOGY) and Cyanophyceae (see ALGAE), which are often grouped together as Schizophyta, are from points of view of both structure and reproduction extremely simple organisms, and stand apart from the remaining groups, which are presumed to have originated directly or indirectly from the Flagellatae, a group of unicellular aquatic organisms combining animal and plant characteristics which may be regarded as the starting-point of unicellular Thallophytes on the one hand and of the Protozoa on the other.
Ordinary soils will almost always provide the necessary chemical ingredients if of proper physical texture, depth, &c. (see FUNGI and BACTERIOLOGY).Advertisement
There is, in addition, a series of bacteria which decompose sulphureous compounds and utilize the element thus liberated in their protoplasm (see Bacteriology).
Experimental pathology has benefited by the use of antiseptic surgery in operations upon animals, and by the adoption of exact methods of recording; while the employment of solid culture media in bacteriology - the product of Koch's fertile genius - is responsible for a great part of the extraordinary development which has taken place in this department of pathological research.
The Royal Institute for experimental therapeutics (Konigl.Institut fiir experimentelle Therapie), moved to Frankfort in 1899, attracts numerous foreign students, and is especially concerned with the study of bacteriology and serums.
But whatever merits they had as clarifiers of turbid water, the advent of bacteriology, and the recognition of the fact that the bacteria of certain diseases may be water-borne, introduced a new criterion of effectiveness, and it was perceived that the removal of solid particles, or even of organic impurities (which were realized to be important not so much because they are dangerous to health per se as because their presence affords grounds for suspecting that the water in which they occur has been exposed to circumstances permitting contamination with infective disease), was not sufficient; the filter must also prevent the passage of pathogenic organisms, and so render the water sterile bacteriologically.
Though the causal relationship of a bacterium to a disease may be completely established by the methods given, another very important part of bacteriology is concerned with the poisons or toxins formed by bacteria.
