The saprophytic bacteria are the bacteria of decay, putrefaction, and fermentation.
The ground bacteria are divided into two groups--saprophytic and pathogenic.
The great majority of bacteria of interest in dairying belong to the saprophytic class; only those species capable of infecting milk through the development of disease in the animal are parasites in the strict sense of the term.
In a number of cases[18] such experiments have been made with various saprophytic forms, such as B.
Most disease-producing species, as diphtheria or typhoid fever, while parasitic in man lead a saprophytic method of life so far as their relation to milk is concerned.
In the second group, the bacterial species lives a saprophytic existence, growing in milk, if it happens to find its way therein.
It will require accurate knowledge of soil bacteria generally to be able to say which saprophytic germs, if any, have no definite function beyond their own existence.
Thus they become contaminated with saprophytic and pathogenic germs contained in the sewage.
Saprophytic bacteria of various kinds are normally present on exposed surfaces of skin or mucous membrane.
In the polishing-room of a well-known hat firm, in which the air appeared to the naked eye to be pure, and in which there was ample ventilation, there were found four or five species of saprophytic bacteria.
Bordoni-Uffreduzzi maintains that the parasitic existence of the Bacillus lepræ may alternate with a saprophytic stage.
Hence we should expect to find in uncooked or stale food an ample supply of saprophytic bacteria.
This group will be referred to under "Saprophytic Bacteria.
The Common Saprophytic Bacteria, whose function is at present but imperfectly known.
The saprophyticorganisms are, generally speaking, those which contribute most to the benefit of man, and the parasitic the reverse, though this statement is only approximately true.
These were probably common species of saprophytic bacteria, which increase readily at a comparatively low temperature.
If saprophytic bacteria are present with pathogenic, there is a struggle for the survival of the latter.
Notwithstanding the absence of chlorophyll, and the consequent parasitic or saprophytic habit, Bacteriaceae agree in so many morphological features with Cyanophyceae that the affinity can hardly be doubted.
Certain species, such as Gymnodinium spirale, are colourless and therefore saprophytic in their method of nutrition.
Dependent plants comprise all fungi and many flowering plants of a parasitic or saprophytic nature.
Defn: A genus of parasitic or saprophytic plants including the Indian pipe and pine sap.
Defn: A large, important class of parasitic or saprophytic fungi, the algal or algalike fungi.
Bacteria may be conveniently grouped under two heads: those that live upon dead organic matter, known as the saprophytic forms, and those that are found in living plants or animals, the true parasites.
Dependent plants comprise all fungi and many flowering plants of a parasitic or saprophytic nature.
A genus of parasitic or saprophytic plants including the Indian pipe and pine sap.
The much more rapid spread of the hyphae up into the parts thus killed sufficiently indicates the fundamentally saprophytic character of such fungi.
The necrosis which results may affect all the tissues, or only the cortex and cambium, and the frequent accompaniment of all kinds of saprophytic Ascomycetes and moulds or other fungi is in no way causal to the phenomenon.
If it can do neither it must either content itself with a saprophytic existence or fail, so far as that particular host-plant is concerned.
Bacteria may further be divided into those which are saprophytic or which find favorable conditions for life outside of the body, and the parasitic.
Thus, such bacteria as tubercle bacilli and the influenza bacillus can be cultivated, but they certainly would not find natural conditions which would make saprophytic growth possible.
Saprophytic and parasitic organisms, wild plants in the household, are studied in their relations to mankind, both as destroyers of food, property and life and as man's invaluable friends.
How molds and other saprophytic fungi do harm to man.
He published papers which added much to our knowledge of the Saprolegnieae a group of fungi of aquatic habit, partly saprophytic and partly parasitic.
He shows that its production would determine the passage from a merely saprophytic to a parasitic habit, and makes the suggestion that an organism might be educated to pass from one to the other.
Nearly all bacteria, owing to the absence of chlorophyll, are saprophytic or parasitic forms.
It is easy to understand the relation of the saprophytic and the holophytic Flagellates to true plants.
These can no more be attacked during their saprophytic existence than those just mentioned.
Organisms like the bacterium of anthrax and the bacillus of black-leg from their local occurrence seem to be distributed from animals infected, though capable of a saprophytic existence outside the body for years.
Most saprophytic organisms and many parasitic ones grow within a wide range of H ion concentration so that titration with phenolphthalein gives sufficient accuracy for media for such organisms.
Though some few kinds cause disease in man and animals, if it were not for the saprophytic bacteria above outlined, there could be no animals and higher plants to acquire these diseases.
Von Fodor (1885) showed that saprophytic bacteria injected into the blood are rapidly destroyed.
In sapremia the blood contains the toxins and dead saprophytic organisms.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "saprophytic" in a variety of sentences. We hope that you will now be able to make sentences using this word.
