“RIFE MICROSCOPE-FILTERABLE BACTERIA”
IS A NEW FIELD OF BACTERIOLOGIC SCIENCE ABOUT TO BE OPENED?
California and Western Medicine
December 4, 1931 Issue
In this issue of CALIFORNIA AND WESTERN , MEDICINE is printed an article having as its co-authors Arthur Isaac Kendall, Ph. D., of the department of research in bacteriology in Northwestern University Medical School, and Royal Raymond Rife, Ph.D., of San Diego, California. The caption of tile article is "Observations on Bacillus Typhosus-In Its Filterable State." The article is commended to the readers of CALIFORNIA AND WESTERN MEDICINE because it is a preliminary communication calling the attention of the world to a new type of microscope, which, if it fulfills its apparent advantages over any microscopes thus far developed, bids fair to lay the basis for revolutionary discoveries in bacteriology and the allied sciences. Whereas our present microscopes magnify from one to two thousand diameters, in this new microscope we have an instrument for which a magnification as high as seventeen thousand diameters is claimed. This is certainly a long stride from the initial efforts of Van Leuwenhoek, whose simple instrument may be said to have laid the foundation for the science of bacteriology which later came into being; and by means of which science much of the world's progress in man's conquest of the infective and other diseases has been made possible.
It is a source of gratification to know that the development of this new instrument which offers so much for medical research in the future took place in good part in California. The paper presented in this issue by Doctors Kendall and Rife was presented at a meeting of Los Angeles and Pasadena colleagues held at the home of Dr. Milbank Johnson of Pasadena, who induced Doctor Kendall of Northwestern to come West to make some special investigations and tests. The meeting was held on November 20, just as this December number of CALIFORNIA AND WESTERN MEDICINE was going to press. The matter seemed so important to the editor that special efforts were made to have the paper appear in this December number. It is hoped to have other communications in future issues.
OBSERVATIONS ON BACILLUS TYPHOSU IN ITS FILTERABLE STATE*
By Arthur Isaac Kendall, Ph. D.
Royal Raymond Rife, Ph. D.
San Diego, California
It seems improbable that viable bacteria in the filterable state have ever been unequivocably seen. Nevertheless, the theoretical and practical importance of filterable forms of bacteria in theoretical and applied biology cannot be denied.
Recently, through the simultaneous availability of the Rife microscope, an instrument combining very high magnification with coordinated resolving power, and a simple procedure for inducing the filterable state in bacteria at will, the possibility of actually demonstrating organisms in this hitherto illusive condition very obviously presented itself.
Two features of the Rife microscope, full details of which will be presented elsewhere, must be specifically mentioned here. First, the entire optical system, including not only the lenses but also the illuminating unit, is made of quartz. In addition, a double wedge quartz prism is mounted between the illuminating unit and the quartz Abbe condenser. The latter can be rotated, with vernier control, through 360 degrees, thereby affording readily controllable polarized light at any required angle. The import of this polarization unit will be discussed later. Inasmuch as this microscope magnifies from 5,000 to 17,000 diameters, it is obviously very necessary to have it mounted upon an immovable foundation.
The organism selected for these experiments was the well known Rawlings strain of .B. typhosus. The immediate history of the culture used is as follows:
October 29, 1931. An agar slant was made of a thrice-plated culture of B. typhosus, Rawlings strain. (Editor's Note: This agar slant was, made in the Laboratory of Research Bacteriology, Northwestern University Medical School, Chicago, Illinois.)
November 2, 4 p. m. Inoculated six cubic centimeters of K (protein) Medium from the agar slant culture.
November 3, 10 a. m. Filtered this culture in 'K Medium of November 2, through a Berkefeld "N" filter. (The culture was diluted with four volumes of sterile physiological saline solution; the vacuum used was less than four inches of water; the total time of filtration was less than ten minutes.)
November 3. One drop of filtrate, representing one-fifth drop of the original culture was introduced into six cubic centimeters of K Medium. Incubated at 37 degrees centigrade. The filtrate was also tested for purity as follows: (1) cultural reactions; (2) sugar fermentation reactions; (3) agglutination with specific typhoid serum. All were typical.
November 5. The forty-eight-hour culture of November 3 in K Medium was filtered, as above, through a Berkefeld "N" filter. One drop of the filtrate was added to six cubic centimeters of K Medium and incubated at 37 degrees centigrade.
November 6. The twenty-four-hour culture of November 5, which grew well, was again filtered. This time the finest Berkefeld filter, "W," was used. As before, a drop of this filtrate was added to six cubic centimeters of K Medium and incubated at 37 degrees centigrade. Growth was abundant November 7.
November 9. The culture was again transferred to K Medium.
November 12. Still another culture was made, in every instance using three loops of culture for the inoculum.
It is worthy of note that this thrice filtered culture of B. typhosus grew quite readily in K Medium as above outlined: after the second filtration it failed to grow in peptone broth. In other words, the organism having become filterable and accustomed to protein media (proteophilic) lost its ability to grow in ordinary peptone containing nutrient broth.
The cultures of November 9 and November 12 were examined under the microscope and there were no discernible bacilli, although the cultures were markedly turbid. Darkfield illumination revealed very small, actively motile granules, and direct observation of these with the oil emersion lens confirmed the presence of these motile granules, without, however, affording any indication of their structure. Therefore, these granules for obvious reasons could not be unequivocably diagnosed as the filterable form of the bacillus.
In this viable, filtered state the culture was taken to Pasadena, California, and, through the instrumentality of Dr. Milbank Johnson, the cooperation of Dr. Alvin G. Foord, and the courtesy of the Pasadena Hospital, the necessary space and equipment for mounting the microscope and continuing the cultures were made available. The subsequent developments, which are the immediate subject of this discussion, are as follows:
November 16. The cultures of November 12, made in Chicago, were transferred to fresh K Medium and incubated at 37 degrees centigrade overnight.
November 17. The Rife microscope was installed and the first cultures, those inoculated November 16, were examined. The preliminary observations of these cultures were made with a polarizing microscope with a spectroscopic attachment. It should be borne in mind that the entire optical system of this micropolarimeter was of quartz. A one-eighteenth-inch apochromatic oil immersion lens was used, with a 20x quartz ocular.
When a culture of B. typhosus in the filterable state, grown as above indicated in K Medium, was examined with this micropolarimeter, it was observed that the plane of polarization of, the light passing through the culture was deviated plus 4.8 degrees, with the simultaneous appearance of a definite blue spectrum. With this observation in mind, the culture was next studied with the Rife microscope at 5000 diameters.
The double wedge quartz prism referred to above was set by means of the vernier to minus 4.8 degrees.* Examined in this polarized light, (*The reason tor setting the quartz wedge In the reverse direction will be discussed in another place) this thrice filtered culture of B. typhosus cultivated in K (protein) Medium showed small, oval granules, many of them quite actively motile. These motile granules when in true focus appeared as bright turquoise-blue bodies, which contrast strikingly, both in color and in their active motion, with the noncolored, nonmotile debris of the medium.
These observations were repeated eight times, using, in each instance growth of the filterable organisms in K Medium. The cultures examined were both twenty-four and forty-eight hours old. The qualitative results were always the same, namely, the occurrence of small, oval, actively motile, turquoise-blue bodies in the cultures and the absence of these small, oval, actively motile, turquoise-blue bodies in the uninoculated control K. Media.
From the two facts thus far arrived at, namely, that the small, oval, turquoise-blue bodies were actively motile and also that they were cultivable from K Medium to K Medium, it is surmised that these small, oval, motile, turquoise-blue bodies are indeed the filterable forms of the B. typhosus.
There is another even more direct procedure for establishing the identity of these small, oval, motile, turquoise-blue bodies. It has been shown in previous communications that agar cultures, or better, broth cultures of B. typhosus inoculated into K Medium, become filterable within eighteen hours' growth at 37 degrees centigrade. It should follow, inasmuch as not all of the bacilli appear to become filterable under these conditions, that at least some of the bacilli should have similar turquoise-blue granules within their substance if they are indeed passing to the filterable state. Also the free swimming filterable forms, the small, oval, motile, turquoise-blue bodies described above, should be simultaneously present.
Darkfield examination of such a culture eighteen hours old revealed unchanged, actively motile bacilli, bacilli with granules within their substance, and free swimming, actively motile granules. This culture examined in the Rife microscope with the quartz prism set at minus 4.8 degrees and with 5000 diameters magnification, showed, very clearly the three types of organisms just descibed, namely:
First, unchanged bacilli: These were relatively long, actively motile, and almost devoid of color.
Second, long, actively motile bacilli, each with a rather prominent granule at one end. The granule in such an organism was turquoise blue, reminiscent in size, shape, and color of the small, oval, actively motile, turquoise-blue granules found in the protein medium (K Medium) where it will be recalled, no formed (rod shaped) bacteria could be demonstrated. These bacilli having the turquoise-blue granules were colored only at the granule end, the remainder of the rod being nearly colorless, in this respect corresponding to the unchanged (nonfilterable) bacilli just mentioned.
Third, free swimming, small, oval, actively motile, turquoise-blue granules, precisely similar, apparently, in size, shape, and color to those seen in the granulated bacilli just describe.
From the fact that these small, oval, turquoise-blue bodies could be seen both in the parent rod and free swimming in the medium, it is assumed that these small, oval, actively motile, turquoise-blue bodies are indeed the filterable form of B. typhosus.
