Many varieties of pyogenic bacteria have now been differentiated, the best known being the staphylococcus aureus, the streptococcus, and the bacillus coli communis. [Illustration: FIG.
Bacteria are commonly given a generic name based upon their microscopic appearance. There are only a few of these names. Micrococcus, Streptococcus, Staphylococcus, Sarcina, Bacterium, Bacillus, Spirillum, are all the names in common use applying to the ordinary bacteria. There are a few others less commonly used.
In the result, despite everything that I could do for him, the boy died though the girl recovered. Both had been vaccinated from the same tube of lymph. In the end I was able to force the authorities to have the contents of tubes obtained from the same source examined microscopically and subjected to the culture test. They were proved to contain the streptococcus or germ of erysipelas.
Infection with the staphylococcus albus, the streptococcus, or the pneumococcus also causes a mild form of osteomyelitis which may go on to suppuration. It occurs in adults, being met with up to the age of fifty or sixty, and is characterised by the insidious development of a swelling which involves a considerable extent of a long bone.
There are a number of "suspects" against which a great deal of circumstantial evidence exists: a streptococcus in scarlet fever, a bacillus in whooping-cough, and a protozoan in measles; but none of these have been definitely convicted.
Now, if you can think of any possible chink through which a wandering streptococcus can, by any possibility, sneak into that wound, please suggest it, and it shall be closed immediately! The intruders against whom all these preparations are made are two in number: Streptococcus pyogenes and Staphylococcus pyogenes cousins, as you see, by their names.
This is the way the streptococcus and staphylococcus behave in an open wound, or sore; but they have two other methods of operating which are somewhat special and peculiar. One of these is where the germ digs and burrows, as it were, underground, in a limited space, resulting in that charming product known as a boil, or a carbuncle.
Cellulitis is an acute affection resulting from the introduction of some organism commonly the streptococcus pyogenes into the cellular connective tissue of the integument, intermuscular septa, tendon sheaths, or other structures.
Suppuration, or the formation of pus, is one of the results of the action of bacteria on the tissues. The invading organism is usually one of the staphylococci, less frequently a streptococcus, and still less frequently one of the other bacteria capable of producing pus, such as the bacillus coli communis, the gonococcus, the pneumococcus, or the typhoid bacillus.
The Streptococcus viridans is one of the most dangerous of these bacteria. Mild endocarditis is rarely a primary affection, and is almost invariably secondary to one of the diseases named above. Nearly 75 percent of secondary endocarditis occurs as a complication of acute articular rheumatism and chorea, or subsequently.
