Definitions
- the box of fig. 3 is round in shape and contains a compartment which occupies about a quarter of the surface. From the place where the two partitions which delimit it join, leaves a partition which divides the remaining part of the box into two parts of equal surfaces.
- the compartments can be separated by simple partitions, or doubled in accordance with Figures i or 2.
- the design of the box in fig ._____ is identical except that the box is square in shape with the small compartment located in one of the four corners.
- 5 is a round box divided by a partition from edge to edge located in one axis and a partition perpendicularly
- the box thus comprises a large compartment occupying approximately half the surface, and two small compartments each occupying approximately a quarter of the surface.
- the partitions can be simple, or lined in accordance with figures l or ______ _ The figure
- the partitions can also be located in the diagonals.
- the partitions have a " height which is preferably five millimeters, thus exceeding by one millimeter the level of the surface of the culture media contained in the compartments, which preferably have a thickness of four millimeters.
- the following examples describe, without limitation, how it is possible to separate the germs present in the inoculum into several distinct categories by a judiciously chosen combination of elective culture media: first example: in oto-rhino cultures laryngological, gynecological, urological and certain pus, in particular of surgical origin, it is advantageous, taking into account the multiplicity of germs present in the inocu ⁇ lum, to be able to separate from the beginning the gram positive germs from gram negative germs and to obtain isolated Neisseria and pathogenic yeasts, given their particular interest.
- the first compartment contains a blood agar, prepared from the medium known as Colurnbia agar base, and en ⁇ rich with 4 to 6 percent defibrinated blood.
- nystatin at the rate of 2 units per milliliter to prevent the growth of yeasts, and colimycin in the form of colistin methane sulfonate at the rate of 20 international units, or 1.7 micrograms per milliliter.
- the second compartment is intended to receive a medium which not only electively promotes the growth of gram-negative germs, but which also makes it possible to identify the Haemophilus species and Neisseria species pathogens. Since there is no medium which meets these requirements, we have invented an ad hoc medium which contains approximately 12 grams of agar, 4 grams of sodium chloride, 10 grams of peptone, 2 grams for one liter. of meat extract, 2 gram of yeast extract, 10 gram of sucrose, 2 international units of nystatin and 15 ml of a 0.25 percent neutral red solution.
- the common species of Neisseria and Haemophilus form red colonies due to the transformation of sucrose and possibly lactose into acid. Not having the ability to attack one or the other of these two sugars, the pathogenic Neisseria develop colorless, translucent and curved colonies, while the different biotypes of Haemophilus influenzae form colorless colonies, translucent and flat.
- enterobacteria and gram negative rods, oxidase positive develop significantly larger and opaque colonies which are white or red depending on whether or not acid is formed.
- the third compartment contains a medium generally called "chocolate agar", prepared from the basic agar medium according to Thayer-Marti at a rate of 40 grams for one liter. After sterilization, lysed defibrinated blood is added to it at a rate of 4 to 6 percent, then the medium is reheated to 80 ° C. for 30 minutes, with regular agitation of the bottle.
- chocolate agar prepared from the basic agar medium according to Thayer-Marti at a rate of 40 grams for one liter. After sterilization, lysed defibrinated blood is added to it at a rate of 4 to 6 percent, then the medium is reheated to 80 ° C. for 30 minutes, with regular agitation of the bottle.
- this medium only allows: growth of Neisseria meningitidis, Neisseria Gonorrhoeae, Candida and Saccharomyces species, Campylobacter species and Bacillus species, in particular Bacillus fusiformis, according to the composition of the culture atmosphere during incubation.
- colimycin Streptococcus agalacteae blood agar can be identified directly. whitish, beta-hemolytic colonies, Streptococcus faecalis, curved, gray, non-hemolytic colonies, Gardnerella vaginalis, small flat colonies, translucent, hemolytic or not, depending on the human or ovine origin of the blood incorporated into the medium, the Corynebacterium species , including Listeria monocytogenes, white or grayish colonies, generally more or less clearly hemolytic when it comes to pathogenic species, the pathogenic Neisseria, curved colonies, trans ⁇ lucid, and Staphylococcus species, especially Staphy-- lococcus aureus, fairly large beta-hemolytic colonies, flat and gray, or curved and yellowish, while the Lactobaci1lus species and Proprionibacterium species appear in the form of small colonies generally alpha-hemolytic, and the Proteus species,
- the germs sought are thus distributed over the three environments in distinct categories and, by the aspects that their colonies present on the particular environment, are directly identifiable there.
- colimycin can be replaced in blood agar by polymyxin B at the rate of 2,500 international units per liter, in serum agar clindamycin by Hncomycin at the rate of 1 milligram by liter, or by a milliliter per liter of a 0.1 percent solution of crystal-violet, and in the chocolate-VCT medium trimethoprim with neomycin at a rate of 2 mg per liter.
- lactose Since the acidification or not of the colonies by the degradation of the lactose alone, highlighted by the transfer of the indicator, is a generally accepted criterion, it suffices to incorporate only lactose at a rate of 10 grams per liter and to abstain from sucrose.
- 1 gram of iron citrate and 6 grams of sodium thiosulphate per liter can be added, and the pH adjusted to 7.2.
- the nystatin is not removed and the serum is only added if the medium must also serve to demonstrate the yeasts and Candida species, and Neisseria gonorrhoeae, respectively.
- the advantage of clindamycin compared to methylviolet is that the former does not hinder the growth of said germs in any way.
- This medium is then poured into the large compartment of a box comprising a large and two small compartments.
- One of the two small compartments receives either the so-called mannitol-salt agar medium intended to highlight the Staphylococcus species, or the coli ⁇ mycin blood agar of the first example, with nalidixic acid and nystatin or amphotericin-B, in order to highlight not only the Staphylococcus species, but also the Streptococcus species, including beta-hemolytics and enterococci, as well as the Neisseria pathogens.
- the second compartment receives the medium according to Slanetz and Bartley, which makes it possible to selectively highlight the enterococci.
- the second small compartment is filled with a medium for the isolation of yeasts and of Candida species, the medium of Sabouraud for example, or the medium of chocolate- VCT of the first example.
- the germs responsible for digestive tract disorders are among the negative gram rods, negative oxidase, namely salmonella, shigella, Yersinia enterocolitica, Yersinia pseudotuberculosis, and the enterotoxic and enteropathogenic strains of Escherichia coli, gram sticks negative, positive oxidase, namely Aeromonas hydrophila, Pleisiomonas shigel loides, Pseudo ⁇ monas aeruginosa, Vibrio choiera and Vibrio parahaemolyticus, several Candida species, notably Candida al-bicans, several species of mold, as well as species of staphylococci alpha toxin.
- negative oxidase namely salmonella, shigella, Yersinia enterocolitica, Yersinia pseudotuberculosis
- enterotoxic and enteropathogenic strains of Escherichia coli gram sticks negative
- our medium therefore contains, in addition to clindamycin or Hnco ⁇ mycin, lactose, 1 erythromycin or rovamy- " cine, and a ferric salt, the latter so that the salmonella colonies stand out for their blackening due to the interaction between iron and sulfur hydroxide formed by the majority of salmonella species.
- This medium is poured into the large compartment of the petri dish divided into a large and two small compartments.
- the two small receive respectively the mannitol-salt agar, for the demonstration of positive mannitol staphylo ⁇ shells, and the medium according to Sabouraud, this latter made elective with respect to mycoses, Candida included, by adding one or more products with antibacterial action, thus providing a set of media which makes it possible to isolate and identify the germs responsible for disorders of the digestive tract.
- the examples given are not limiting: the elements which constitute this invention lend themselves to variants, such as the number of large and small sectors of the supports for culture media, which can be greater than mentioned, for example following Figures 7 and 8.
- the shape of the petri dishes which can be rectangular, rather than square or round, the design of the double partitions, which is applicable to all supports for culture media having at least two sectors, combinations of media elective and selective, which can be chosen differently depending on the nature of the inoculum, as well as the volume and the concentration of their constituents, which can vary according to the origin of the products, the degree of electivity and the reaction intensity that one wishes to obtain.
- blue china is more suitable for color blind people as an indicator of acidity.
