REZIME

Elanovi roda Aeromonas su koloformne, fakultativno anaerobne i oksidaza pozitivne bakterije.
Zbog nedostatka pripadnosti izmeĊu patogenih i genotipskih karakteristika vrste, elanove roda
Aeromonas teško je karakterisati kao patogene ili genotipske bakterije. Mogu se pronadi u raznim
vodenim sredinama (podzemne vode, površinske vode, vode estuara i marina, pijada voda, otpadne
vode...) i u hrani. Zbog njihovog stalnog prisustva u vodi mogu prouzrokovati razna oboljenja riba, a
samim tim i eoveka. Da bismo dokazali njihovu prisutnost u vodi dva puta smo ispitivali vodu Dunava gde
se ispušta otpadna voda iz kolektora vodovoda Banovci-Dunav. Prvi put smo ispitivali uzorak vode pre
ispuštanja otpadne vode iz kolektora, drugi put uzorak vode posle ispštanja otpadne vode iz kolektora. U
ispitivanju uzoraka vode, vršene su tri vrste ispitivanja : mikrobiološka ispitivanja vode, fizieko-hemijska
ispitivanja vode i ispitivanje metala iz vode. Ispitivanja su vršena 11.12.2014. u 12:00 sati metodama koje
koristi JKP VODOVOD I KANALIZACIJA jp-STARA PAZOVA. Na osnovu dobijenih rezultata analize,
dokazano je da postoji 1100 cfu/100ml koloformnih bakterija pre izlivanja otpadne vode iz kolektora u
Dunav i 1000 cfu/100ml koliformnih bakterija posle izlivanja otpadne vode izkolektora u Dunav.

Ključne reči: Aeromonas, patogene bakterije, kolektor, koliformne bakterije.

SUMMARY

Members of the genus Aeromonas are coliform, facultative anaerobic and oxidase positive
bacteria. Due to the lack of affiliation between pathogenic and genotypic characteristics of the species,
members of the genus Aeromonas is hard to characterize as pathogenic or genotypic bacteria. They can
be found in various aquatic environments (groundwater, surface water, estuary water and marina,
drinking water, waste water ...) and in food. Because of their constant presence in water they can cause
various diseases of fish, that can also effect a man through a food chain. To prove their presence in
water, we examined the water of the Danube twice, where the water drains from sewer water supply
Banovci-Danube. The first time we tested a sample of water before discharging out of a collector, the
second time a water sample was taken after discharging out of collectors. In testing of water samples
there were carried out three types of tests: microbiological testing of water, physical and chemical
testing of water and testing of metals from water. Tests were conducted 11/12/2014. at 12:00. Tests
were carried out on the basis of the methods used by “JKP VODOVOD I KANALIZACIJA jp-STARA
PAZOVA”. Based on the test results, it has been proven that in both samples are 1100 cfu / 100ml
coliform bacteria before pouring waste water from the collector to the Danube and 1000 cfu / 100ml
coliform bacteria after pouring waste water out of collector in to the Danube.
