Reservoirs of Brucellosis in Poland
In our country, cattle are the brucellosis reservoir and, in the light of
our observations and research, arc practically the sole ^,ource of humnn infec-
tion. Despite extensive research in various sections of the country, we have
not, up to notir, been able to deruonstrate the existence of brucellosis among
sheen, goats, or swine. It may be that in cur country, these aniLUSls do not
play a very great role us reservoirs of brucellosis. This matter, however, re-
quires i'urtlrer verification. Only sporadic cases of brucellosis anion;; horses
have been reported by .lnczu'rowski and Sznflarski. tdeither our investigations
of many herds in which mares have aborted, nor mass investigations of horses
on FGRs(Pansttirowe Gospodnrstwa Rolne, State Farms) where there xere cattle
suffering from brucellosis, have revealed the infection among horses. Brucel-
losis anion;; fowl, dogs, rodents, rabbits, and other animals has rurrly been
confirmed. Investigations of rodents Y,illed on FGRs where cattle were in-
fected with brucellosis tLive yielded very few positive serological :?esults.
rr^urther research on rodents (rats, house mice, field mice, and forast mice)
is required. Initial research on arthropcds parasitizing cattle infected rrith
brucellosis have not yielded positive results. This research will be continued.
The Brucellosis t?iicroor,ranism
The forme.? statistical division of Br?ucellae into separate, individual
species, i. e., Br. aUortus bovis, Br. melitensis, and Dr. suis, no loner pre-
vails. :it present, we distinguish the folloti:in!; variants of the species Brucel-
lae: bovis, suis, and melitensis. extensive research has confirmed the correct-
ness cf the L?hesis that these variants are not stuUle i:nd that in response t-o en-
vironmeutal changes, they are able to transfer from one host to another and can
under?o transfornwtions. r. correlation can be established between the ecological
characteristics o_" a ;,eo~raphic area and the appearance of a certain variant. Br.
melitensis appear^, mainly in the Idediterranean basin, in the southeastern areas
of the USSR, in southern France, etc. Br. bovis is distributed throughout Europe,
Asia, and Ilorth ;unerica in r,rees corresponding to our latitude. Br. suis appears
in the US, Dertrrark, and the U(iSR. This principle, however, can not be considered
stntistically invariable. Sheep transported from the south to the north of the
USSR carry Dr. melitensis with them, and these or;anisms are able both to adapt
to the chan;;ed ecoloLical conditions and to preserve their vitality, virulence,
and infectiveness for humans and animals. Thus, the theory concerning the so-
called mild virulence and infectiveness of Br. bovis can no longer be maintained.
an increase in the virulence of Br. bovis has been observed. Brucell~:c isolated
from hiun:-ns ; s a variant of Br. bovis can not be distin~;t~ished fron the vir?.rlent
melitenuic variant.
llhich variant do ve encounter in Foland'(
Only tine cattle v:xrinnt was reported before the war. S.t that time, our
collection of B:?ucella strains cordpriscd about lu0 native strains and the st~nd-
ard variants: bovis, melitensis, and suis. ;1e shall attempt t-o describe the var-
iants found in our country. Up to now, our invests?aticns have disclosed only
cattle variants.

The mutability of Brucellae is very ~?reat. They appear, in S, R, SR, ht, I,
and other forms. The R form is the most important one for the selection of vac-
cine strains, for serological purification, for the production of allergen, and
for the production of vaccines. The others are not suitable for dia?nostic pur-
poses or for the production of vaccines. ~^s a basis for many experiments, we
found Brown's method of thermoag~lutination and Daszkiewicz's method of acrifla-
vine agglutination to be the most advantageous for laboratory work.
