velopment of the infection with serious universal poisoning is accomanied by a
vehement proliferation of the microbPs at the site of their intrusion and by their

of the antimicrobic UNIM factor in the mechanism of immunity against the Clostri.
dium perfringenso and about the appropriateness of including microbic components in
an antigen predestined for active immunisation against gas gangrene caused by the
perfringeite bacIllus
The litPrature is not very large on this question WEINBERG and other eo in a
series of investigations( 2927. 1929) had obtained the reinforcement of anti,infeccp
tious substances of the antipprfringens serums after the inclusion of microbic bodie
of the Type A Clostridium perfringens in the antigen meant for immunization
ar results were obtained by LAKHIERI(1938) and VINOENT(1939)0
The cited works do not determineohowevero the role of the antibacterial factor
in the mechanism of the passive antiperfringens immunity (1)05) since the different
effectiveness of the obtained sera could be conditioned not only by the presence
or the absence of the antibacterial factor? but also by their different contents
in antitoxino which has been also later convincingly shown by 0,I0LETKOVICH(1945)
LEVICOVICE proved that the effectiveness of the antiperfringens sera which were pre.,?
pared by means of introducing various antigens(of microbic bodiesf, of toxin and
anatoxin) had depeneed only upon the level of the obtained antitoxic titre.

perfringens bacillus. The infection was done intramuscularly into the rear paw,with
the spores of B.nerfringens, activated with 0.1 ml of a 50% solution of Ca0120
The conducted studies permitted to draw the following conclusions
1) The Immunization of the rabbits with the concentrated sorbed perfringene
anatoxin causes in the organism of the animals the formation of a considerable
amount of antitoxin which fully protects them from experimentil gas gangrene caused
by the perfringens bacillus The addition of various microbic fractions to the ana
toxin provokes the formation of bacterial antibodiespbut it does not help the in..
crease of the antitoxin production.
2). The immunieation of the rabbits with anatoxic protein fractions of the
microbic cells of the perfringens bacillus will provoke in the immunired animals
the formation of agglutinin-,..-precipitins0 of complement.binding antibodies and,
evidently? it imparts a slightly marked anti-soinfectional immunity to lait separate
animals,

to the immunity against B.perfringensotoo. ZELEVINSKAYA0 VOLKOVA and BULATOVL es.
tablished that the purification and concentration of the perfringens anatoxins with
the aid of-ammontum sulfate or with the salt of heavy metal(Cd) permits the ob=
taming of considerably stronger antigens than with tie native anatoxins, The pos. /
sibility has been also found that immunity can be experimentally produced against
tetanus and gas gangrene due to the perfringens bacillus and to the edematlens ba,
cillus by the use of a composite preparation for the immunization.
As it can be seen from the available literature? the slight efficiency of re=
search in relation to the specific prevention from gas gangrene is connected with
the difficulties of getting preventive preparations( anatoxins) which would have
sufficient antigenicity and immunogenicity,? However? ADAMS(1947)0 TAITL & LOGAN
(1947)0 thanks to the bivalent immunization and the revaccination of volunteers with
perfringens plus edematiens anatoxinso have detected perfringens antitoxin In

the other hand? according to the data of ADAMS(1947)0 TAITL & LOW(1948), and
BERNHEIMMR(1947)0 the use of precipitated and concentrated anatoxins allowed to get
positive results under the condition of a compulsory performance of revaccination
in a period of 6 to 12 months after the immunization. This has been also pointed
out by MAUS() who thought that a stimulating dose is required some time after
the initial injection for a high level of immunity.

The modern status of lenowledge about the antigens cnd the. broad development Of
immunochemicale research makes it possible to considerably strengthen the range of
action of the preventive preparations by employing purified and concentrated preper
arations simultaneously against several infectioni, This circumstance has a pro.
found importance for the active immanizationft against wound infections?
What kind of coneiitions are then required and which are satisfactory for the
development of this really new stage in the field of practical immunology?
The production of immunogenic complex preparations for active immunization
against wound infections is tied up with 1) the investigation and study of new
nutrient media which are best for the formation of toxins, and the production of
the toxins; with 2) a study of the process of detoxication of the toxins which are
obtained on the above indicated media, for the purpose of getting anatoxins; with
3) the elaboration of the methods of purification and concentration of the toxins
and anatoxine whichoin the presence of a Small amount of the preparation, will per.
mit to reach the maximum immunological effect as a result of the active immuniza=
tion with 4) the study of the process of sorption of the anatoxins for the purpose
of strengthening their antigenic and immunogenic properties.
Considerable interest is concentrated on the results of the elaboration of a
new method for getting anaerobic toxins by means of the breeding of a culture of
anaerobe germs in cellophane bags; the method had ben undertaken by S,A,ZELEITINS,
KATA, E,A,GIL2GUT, N0S,XASHIYTETVA, I,B"LANOVALE4V,VIAS0VA and GFRMCKINA?

ins, at the addition of 0.3 Q. 0.4% formalin0 will change into enatoxins in a short.
er period of time than the ordinary toxins. The anatoxins obtained from the "dia.
lyzed" toxins possess higher antigenic and immunogenic reoperties. Their immunolog.
ical effectiveness is several times higher than of tt ordinary anatoxins. A. seri.
ons shortcoming of the elaborated method has been the difficulty of creating the
conditions which are reouired for getting "dialyzed" toxins in large volume for the
purpose of wholesale production.
The native preparations.even those of considerable antigenic power.which are
prepared on meat media of hardly definable and of changing chemical composition0
are sufficiently effective in themselves( for instance. the native tetanus anatoxin)
Yet.they do not satisfy the basic requirements that can be claimed for the compon.
ents of the complex preparations.which reeuirements consists above all in high pu.
? rity and high concentration so that in a small volume the highest possible amount
? of fullevalue antigens should be included.
In connection with the study of the indicated questious, the collective team
of the Department of Wound Infections of the N,F0GAMALEI Institute of Voidemiology
and Microbiology of the Medical Science Academy of the U.Sb.S.R.0 with the jointly

reached 5 AcI%, the titre of the botulinus A reached 4 AAr,,, and the titre of the
nerfringens was 1 AOIL In this way, it could be successfully shown that, with suffi
cient dosage(of the antigen) the introduction of the botulinus A and B anitoxins
into the composition of the pentaaanatoxin assures a considerable increase in the
titres of the botulinus antitoxins and it does net opnress the formation of the
ether antitoxins called for by the other components of the penta.anatoxinO
The obtained data permitted for us to develop the researches for the study of
the immunogenicity ef the tril and pesta.anatoxins in combined preparation ? with

injection of the new combined preventive preparations against wound infection, the
reaction to the trianatoxin and to the penta.anatoxin which were worked out in the
N,F0GAMALEI Institute, is of interest from both a practical and a theoretical paint
of view.
The illumination of this question has an important meaning for the judgment
en the reactogenicity of the preparation and for the study of the processes which
occur in the lymphatic nodules at the time of iamunogenesis.
By the investigations of VYGoDCHIKOV,VOLKOVA,ZELEVrFSKAYA,KASPINTSEVAJLASOCA
and GIL0GUT(1957) the high immanogenic.propertiee of tha trianatoxin and of the
tetraanatoxin have been proved, and their practical lack of reactogenicity was
shown in experiments on animals and at imiranization of vo1unter The obtained
rPsults allowed the use of the trianatoxin for the immunization of people with 'nos,
itive findings(PONOMAREV0BRYZGALOVA01956; KONDEAMV0.956),
From the large number of published works,it is known that the formation of the
antibodies(antitoxins) happens basically in the lymphatic aode s which are regional

and in the spleen,? MCMASTER and HUD,
ACK(1925)0and thereafter EHRION and HARRIS(1942) have already established that the

Later on, many investigators corroborated these findings by utilizing various
methods;their confirmations were direct or indirect(cf0 the review articles 'OESY.

In recent times it has been established that the synthesis of the protein sub.
stances which are required for the [-rowth and for the division of the cells as well
as the secretion of the protein gubstances by the cells are achieved with the par-
ticipation of ribonucleic acid. For the synthesis of the proteins a preliminary

From the data quotPd in this work it is evident that the introduntion of the

the cells of the lymph nodes? EHRIOH,DRABKIN and FORMAN(1949) as well as HARRIS
and HARRIS(1949)0 by using biochemical and histochemical methods, have established
that, after the immunisation with different antigens, the amount of the ribonucleic
acid will increase in the regional lymph nodes.

that the ribonucleic acid which was newly formed after the immunization took part
in at least two processesee in the hyperplastic process(multiplication of the eel..

theria anatoxin.
The conducted experiments did not rermit to notice a marked comretition of
the anatoxins which were put into the combined prevaration.
This problem? in regard to the PDT and the A:ODT was left open by us since it
requires serious elaboration which could not be done during the preliminery ex.
nerimentse It should be remarked that the competition will be necessarily visible
and noticeable if the'quantitative ratios of the antigens will not matCh. To cor.
rectly balance the antigens in the combined samples Is not an easy matter; how.
ever we endeavour to do this in our further work.
CONCLUSTONS
1) the rertussieediphtheria.tetanus vaccine(PDT) can be produced from native
and purified anatoxinsowith the additon of the pertussis vaccine, The adsorbed
(p090)pertussis.diphtheria.tetanus vaccine(APDT) Is produced from purified sorbed
anatoxins with the subsequent tr'elition to it of the pertussis vaccine.
2) The harmleesness of the PDT and of the APDToin regard to the pertussis
componento is checked on white mice in compliance with the Instruction for the
testing of the harmlessness of the vertussis veccine. The harmlessness of the PDT
and of the APDToin regard to the tetanus and the diphtheria components? is checked
on guinea pigs by means of inoculation of 3 mi, of the vaccine under the skIn
04`
ee
the flank( in two times eArth with 1.5 ml)o
3)0In comparison with the PDT? the APDT possesses a great immunogenic effec=
tiveness in regard to the tetanus and the diphtheria components?
4) The immunogenicity of the pertursis component in the PDT and in the APDT
has been the same which is also in the initial series of the vertu sis vaccine.

From these data it follows that,with the evaluation in units of extivity,
the dialyzed anatoxins have contained 4=6 times leemballast proteins thim the reg.
ular anatoxins.
The immunogenic properties of the three series of dialyzed anatoxins incon
parison with the first series of ordinary anatoxin r were determined in exnerime,ts
on guinea pigs. The animals(12 guindea pigs in each group) were immunized with onl
shot of one ml of anatoxin precipitated by 0.51, potassium alum. Moreover, 20 guinev,
pigs( 5 in each group) were immunized with one ml of native anatorin0 both dialyzo.
and ordinary.
The anatoxin content was determined 10.20,and 30 days after the immunization.
The results of the experiments are given in the illustration.
The exneriments proved that the immunizing effect of the native dialyzed ana.
toxin is smaller than that of the ordinary one notwithstanding the large content
of antigenic units within it. The immunogenic properties of the precipitated dia.
lyzed anatoxins proved to be somewhat better than those of the ordinary ones, More.

CONCLUSIONS*
1) At the cultivation of glostridium edemntiens cultures in cellophane bags
which are immersed in nutrient media, o toxins were obtained which were 20 to 50
times superior to those of the cultivation with the ordinary method and which con.
tamed 10 000 to 100 000 Dlm/ml,
2) HowevPr, notwithstanding the great power? the dialyzed toxins are trans.
formed into anatoxins with the addition of O44 of formalin,and with keeping them
in the thrrmostat at 3700 for the same length of time as the ordinary toxins(48 h,).
3) The dialysed anatoxins contained UX46 times less ballast proteinpand 4.10
times/ less total nitrogen per unit of effectiveness of the preparttion.
4) In the work, data were introduced about the study of the antigenic and im
* ? r ?
munogenic properties of the dialyzed anatoxins.

As it is known, the native gangrene anatoxins have small effectiveness; in
the Cl.oedematiensolt makes 5 =5O/ Bounits0 Moreover? they contain a large amount
of ballast protein pigment substances? and other remnants of the nutrient media.
These prnperties of the native anatoxins hinder their utilization for the pure
pose of immunization against infection? and they force us to submit them to puri.

The methods of purification and concentration of the Clooedematiens anatoxins

The rabbits of three groups0wighing each 2.0 to 2.3 Kg(three rabits in each

animals was done two months later The content of edematiens antitoxin was exam=

the usual statistical treatment(see above). Its results are given in the Pigure.
After the first immanization0the preparrAions which contained 5.0 and 10,96
mg of Al(OH) revealed definite immunological superiority over the antigen with
0,56 mg of aluminum hydroxide. Between the first two preparations, no notice We
differences could be found in the immunogenic capecity. After revaccination, the
effectiveness of all three antigens was roughly identical. In this manner, the
results of the first immunization of the rabbits indicated that the increase In th
amount of A1(OR)3 in the preparation over the amount whiCh was required for the
full sorption of the antigen(frem 0.56 to 5.0 mg) has increased the immunogenicIty

increase in the concentration of the aluminum hydroxide(up.to 10.96 mg) proved
to be ineffective.
In Connection with thie?we suggest that,at the Choice of the dose of the ad.

concentration of the adsorbent which gives a full sorption of the antigen, It is
necessary to bring to light the optimum dose of the adsorbent which assures the

Among the equine productors of therapeutic sera0sometimes cases of gas gangrene
are observed? Thus0ZANNOLLI and CATIWO(1925) describe a few cases of gas gangrene
in equine productors of various sera, In the majority of the cases0 these authors
have distinguished Clohistolyticum as well as other anaerobes(O10septicum0C10per.
fringens, Clpoedematiens). These anaerobes were sometimes isolated in association
with each other as well as with other aerobes not identified by the authors0 knaeroc
bie microbes were also isolated from abscesses at the site of the inoculation of an
antigen. In a number of cases? upon the inoculation of 01.histolyticumea specific
serum was used which showed a therapeutic effectiveness.
In the native literature0we were unable to detect data about the gas gangrene
in equine Droductors of therapeutic sera. One of the

From 1951 to 19550 among the equine productors of the antitetenus serum two
cases of gas gangrene were observed? In both instances0 a highly toxigenic culture

of Epidemiology and Microbiology( BLAGOVESHOHMSXII and others 1956). The produced
preparations contained 600 . 1500 B U. Per mlo depending upon the quality of the
initial preparation and upon the degree of concentration.
The antigenic and immunoFenic properties of the native and of the concentrated
preparations were examined on small laboratory animals( VLASOVAMILEVIIMVIA0VOL.

produced preparations. All the above discussed data permitted us to take the indica.

the purpose of producing powerful toxins of the tetanus bacillus, we have
also employed the cellonhane bags.
At the growing of a culture in cellophane bags we used various utensils which
we modified into corresponding suitable Shapes. Into a 5.1iter flAstkowith 3,5 ii.,
tere of nutrient medium in it, we let down a doubly everted bag one end of which
we tied tightly and fastened to the neck of the flask0 and the other end we put on
the neck of the flask, Then, we poured physiological solution into the cellophane
bagoup to the level of the nutrient mediump and we inserted a siphon into it0 with
a cotton plu, For taking a sample from the nutrient medium, we also inserted a tu.
bule into the flask; the tubule was placed between the cellophane bag and the neck
of the flask,
We have arranged the fourth (flask) slightly differently0 Into the fourth
we poured two liters of nutrient medium0 and we inserted a siphon Into it to which
we tightly fastened a doubly everted cellophane bag, and we filled it with phyaol

As it can be seen, the amount of antitoxin in the two following grotrps as
almost identical.
It is evident that in case of a two.shot injection it is not necessary to
strive for large doses of antigen. It is likely that there esists some kind cf
limit in this respect; it can be also thought that the amount of antitoxin dues
not accumulate in proportion with the Increase in the antigen? which is almady

In our exaeriments with the concentrated and purified anatoxino as it has been
already indicatedoin the exnerimental animals we' had a small amount of antitoxin
which finally0 in such an acute experiment and in the presence of such a massive dose
of the infection could not protect them from tetanus. Thereforeoin the present case,
it is impossible to talk of a change in the structure of the anatoxin in consecuence
to its purification. At the same timeo the 7arifie1 adsorbed anatoxin has imparted
a high immunity to the animalsowhich immunity nermitted to protect them from /205 -

the following experiment was staged for the purpose of a comparative study of the
Immunising activity and effectiveness of the native sorbed and of the purified or

The native sorbed tetanus anatoxin was used for the reason because the effect.

native antigenso which was found by us in the preceding work.
For the comparative study of the antigens an experiment of single.shot and two.
