Title Pojavnost P. aeruginosa u moru za kupanje na području grada Rijeke Title (english) Occurrence of P. aeruginosa in the coastal water in the area of the city of Rijeka Author Andrea Huskić Mentor Darija Vukić Lušić (mentor)Committee member Marin Glad (predsjednik povjerenstva)Committee member Arijana Cenov (član povjerenstva)Committee member Dražen Lušić (član povjerenstva)Granter University of Rijeka Defense date and country 2023-09-20, Croatia Scientific / art field, BIOMEDICINE AND HEALTHCARE Abstract Monitoring kakvoće mora za kupanje provodi se prema Uredbi o kakvoći mora za kupanje (NN 73/08) a rutinski mikrobiološki parametri su indikatori fekalnog onečišćenja (E. coli i crijevni enterokoki). Fekalno onečišćenje nastaje kada u vodi dospiju mikroorganizmi koji uzrokuju bolesti, a čiji izvor su ljudski i životinjski izmet te izlučevine. Uz rutinske pokazatelje fekalne kontaminacije, prema preporuci Svjetske zdravstvene organizacije mogu se ispitivati i dodatni mikrobiološki pokazatelji, kao Pseudomonas aeruginosa. To je bakterija sveprisutna u okolišu, koja uzrokuje kožne osipe te infekcije oka i uha nakon izloženosti kontaminiranoj vodi ili moru. Cilj ovog istraživanja bio je ispitivanje pojavnosti i koncentracije P. aeruginosa u moru za kupanje na području urbanih plaža zapadnog dijela grada Rijeke (Kantrida), u različitim okolišnim uvjetima. Uzorkovanje se provodilo na četiri plaže, i šest lokacija: 3. Maj, Kantrida istok i zapad, nogometno igralište, Ploče istok i zapad. Tijekom istraživanja provedena su dva uzorkovanja u razdoblju od 2.2.2023. do 27.02.2023. Prvo uzrokovanje bilo je tijekom sušnog razdoblja, a drugo tijekom kišnog. Dodatno, obrađeni su i podaci dodatnog intenzivnog istraživanja koje se provodilo u razdoblju od 2012. do 2014., godine na istim lokacijama. Za ispitivanje P. aeruginosa u uzorcima morske vode primijenjena je ISO norma HRN EN ISO 16266:2008. Rezultati istraživanja su pokazali da na pojavnost P. aeruginosa značajno utječu oborine i dotoci slatke vode, a da je more za kupanje na području grada Rijeke slabo je do srednje opterećeno s P. aeruginosa. Utvrđena je pozitivna korelacija između P. aeruginosa i ostalih fekalnih i ne-fekalnih mikrobioloških pokazatelja. Monitoring rutinskih pokazatelja (E. coli i enterokoki) ne isključuje u potpunosti mogućnost kontakta i zaraze kupača sa bakterijama vrste P. aeruginosa. Javno zdravstveni rizik od infekcije P. aeruginosa raste, uslijed višestruka otpornost na lijekove ove bakterije te slabljenja imunološkog odgovora populacije.
Abstract (english) Monitoring of the quality of the bathing sea is carried out according to the Regulation on the quality of the bathing sea (NN 73/08), and routine microbiological parameters are indicators of fecal pollution (E. coli and intestinal enterococci). Fecal pollution occurs when microorganisms that cause diseases reach the water, and the source of which are human and animal feces and excreta. In addition to routine indicators of fecal contamination, additional microbiological contamination, additional microbiological indicators, such as Pseudomonas aeruginosa, can be tested according to the recommendation of the World Health Organization. Iti s a bacterium ubiquitous in the environment, which causes skin rashes and eye and ear infections after exposure to contaminated water or the sea. The aim of this research was to examine the occurrence and concentration of P. aeruginosa in the bathing sea in the area of urban beaches in the western part of the city of Rijeka (Kantrida), under different environmental conditions. Sampling was carried out on four beaches and six locations: 3. Maj, Kantrida east and west, Nogometno igralište, Ploče east and west. During the research, two samplings were carried out in the period from February 2, 2023. until 27.02.2023. The first occurrence was during the dry season, and the second during the rainy season. In addition, the dana of the additional intensive research conducted in the period from 2012 to 2014, in the same locations, were also processed. The ISO norm HRN EN ISO 16266:2008 was applied for testing P. aeruginosa in seawater sampples. The results of the research showed that the occurrence of P. aeruginosa is significantly influenced by precipitation and freshwater inflows, and that the bathing sea in the area of the city of Rijeka is slightly to moderately loaded with P. aeruginosa. Positive correlation was established between P. aeruginosa and other fecal and non-fecal microbiological indicators. Monitoring of routine indicators (E. coli and enterococci) does not completely exclude the possibility of contact and infection of bathers with P. aeruginosa bacteria. The public health risk of P. aeruginosa infection is increasing, due to the multiple drug resistance of this bacterium and the weakening of the populations immune response.
