Abstract

Respiratorne infekcije imaju izrazito visoku pojavu medu gradskom populacijom, poglavito u osoba izlofonim lošim mikroklimatskim uvjetima i među pojedincima s povećanim brojem izolacija Staphylococcus aureus iz nazofariksa, te u osoba koje duže borave u zatvorenom prostoru gdje boravi velik broj ljudi. Istraživano je inhibitorno djelovanje eteričnih ulja lavande, lovora, čempresa, kadulje, čajevca, ružmarina, melise, eukaliptusa, timijana i cedra na koagulaza pozitivne i negativne stafilokoke,... More te penicilin osjetljive i rezistentne soj eve izolirane iz nosne sluznice stanovnika uieg sredista Zagreba. Sva testirana ulja pokazala su manju ili veću antimikrobnu aktivnost.
Koagulaza pozitivne sojeve stafilokoka vise inhibiraju ulja lavande, lovora, čempresa, kadulje i ružmarina, a koagulaza negativne, eterična ulja timijana i matičnjaka. Na penicilin rezistentne stafilokoke najjače inhibitorno djelovanje pokazuju eterična ulja timijana, lavande i melise. Oboljeli od respiratorne infekcije koji su redovito primjenjivali inhalaciju eteričnim uljima propisanim prema aroma-antibiogramu, te primijenili odoriranje radnog i stambenog prostora terakota tikvicama ili mirisnim svjetiljkama uz evaporaciju eteričnih ulja smanjili su učestalost opetovanih respiratornih infekcija u periodu od dvije godine.

Abstract (english)

The incidence of respiratory infections is particularly high among the city population, possibly persons exposed to bad microclimatic conditions (microbial and other agents), and individual with the increasing number of Staphylococcus aureus isolates from nasopharynx and among the persons crowded on the closed areas. The inhibitory activity of essential oils of lavander, laurel, cypress, sage, tea tree, rosemary, melissa, eucalyptus, thyme and cedar was tested on coagulase positive and... More negative staphylococci, penicillin-sensitive and penicillin-resistant staphylococci, isolated from the nasal mucous membranes of residents in the very heart of Zagreb. All tested oils exhibited the significant antimicrobial activity. Coagulase positive staphylococci were more inhibited by essential oils from lavander, laurel, cypress, sage and rosemary, while the essential oils from thyme and melissa were more effective on coagulase negative staphylococci . The strongest antimicrobial activity of essential oils on penicillin¬ resistant staphylococci exhibited thyme, lavander and melissa. The incidence of the repeated respiratory infections in the two years period was significantly decreased among the persons who were treated with essential oils inhalations¬ according to aroma-antibiograme, and continued to smell and refresh the air in their working room and apartments with clay pots and aromatic oil-lights that evaporated essential oils.

Abstract (german)

Die Inzidenz von respiratorischen Infekten ist in der Stadbevölkerung besonders hoch, hauptsächtlich bei Menschen, die ungüstige mikroklimatische Bedingungen ausgesetzt sind, auch bei Personen denen Staphylokokkus aureus aus Nasopharynx isoliert geworden wurde, sowie bei denen die sich die längere Zeit in engem geschlossenen Raum behalten. In dieser Arbeit wurden die inhibitorischen Effekte von ätherischen Ölen aus Lavendel, Lorbeer, Zypresse, Salbei, Teebaum, Rosmarin, Melisse,... More Eukalyptus, Thymian und Zeder auf das Wachstum von Koagulase-negativen und Koagulase-positiven Staphylokokken, sowie penicillinempfindlichen und penicillinresistenten Staphylokokken getestet , die aus Nasenabstrichen von Bewohnern der Stadt Zagreb isoliert wurden. Alle untersuchten Öle zeigten eine mehr oder weniger starke antimikrobielle Aktivität. Koagulase-positive Staphylokokken wurden durch die ätherischen Öle aus Lavendel, Lorbeer, Zypressen, Salbei und Rosmarin am stärksten gehemmt, während die ätherischen Öle aus Thymian und Melissa auf Koagulase-negative Staphylokokken bessere Wirkung zeigten. Die stärkste antimikrobielle Aktivität gegenüber penicillinresistenten Stphylokokken war bei Thymian, Melissa und Lavendel zu beobachten. Patienten, die regelmäßig gemäß dem Aroma-Antibiogram verschriebene ätherische Öle inhalierten, und die sie mit Duftlampen und Teracotta-Fläschchen auch in Wohn-und Arbeiträumen anwendeten, reduzierten die Häufigkeit wiederkehrender respiratorischer Infektionen in der Beobachtungsperiode von zwei Jahren durch die Verbesserung der mikroklimatischen Bedingungen in ihrem Lebensraum.
