W pracy przedstawiono postępowanie diagnostyczne i profilaktyczne w związku ze zgłoszeniem rozpoznania choroby zakaźnej z początkowym podejrzeniem biegunki podróżnych u pacjenta powracającego z Włoch w sierpniu 2018 roku. Na podstawie badań lekarskich, laboratoryjnych oraz danych uzyskanych z wywiadu epidemiologicznego ustalono, że czynnikami wywołującymi zachorowanie były gatunki bakterii Vibrio alginolyticus oraz Aeromonas hydrophila należące do rodzaju Vibrio. Prawdopodobnie wzrost temperatury mórz jako konsekwencja globalnego ocieplenia klimatu skutkuje częstszymi infekcjami wywoływanymi przez V. alginolyticus i A. hydrophila u ludzi, co jeszcze nie jest uwzględniane w tradycyjnej diagnostyce mikrobiologicznej.

The paper presents the diagnostic and prophylactic procedure in connection with a case of on infectious disease initially diagnosed as travelers' diarrhoea in a patient returning from Italy in August 2018. Based on medical examination and laboratory tests as well as data obtained from the epidemiological inquiry, the species of bacteria Vibrio alginolyticus and Aeromonas hydrophila of the Vibrio genus were determined as the cause of the disease. Probably the increase in the sea temperature, as a consequence of global warming, results in more frequent infections in humans caused by V. alginolyticus and A. hydrophila, which has not been taken into account in traditional microbiological diagnostics so far.

The aluminium contaminated soil is currently being a concern due to the use of aluminium waste as a material for building roads and river dams in Jombang District, Jawa Timur Province, Indonesia. This application was debated because aluminium waste is categorized as hazardous waste. One widely known method for treating the metal contaminated soil is bioremediation. One potential indigenous bacterial species to remove aluminium, Vibrio alginolyticus was isolated from contaminated soil. A toxicity test to V. alginolyticus showed that this bacterium could grow in aluminium contaminated soil until 100 mg/L equal to 48 mg/kg concentration. The removal of aluminium from soil was conducted by using 50 and 100 mg/L concentration. The result showed that the addition of 2% v/v of V. alginolyticus can remove 5.48% aluminium from 100mg/L contaminated soil initial concentration after 12 days of test period. The addition of V. alginolyticus did not significantly influence the removal of aluminium from contaminated soil (p>0.05).

East coast of Algeria suffers from several types of pollution, mainly hydrocarbons. The hydrocarbon-based bacteria of the littoral were investigated. 53 indigenous strains were isolated, identified according to morphological and biochemical nature. Dietzia sp. CNJ898 PLO4 and Vibrio alginolyticus PB-WC 11099 were selected for growth tests in the presence of monoaromatic hydrocarbons as a sole source of carbon and energy and total hydrocarbons at the end of growth. The results showed that both strains used monoaromatics to grow. The total hydrocarbons determined after growth showed that all monoaromatics were biodegraded with different rates. The maximum rate was obtained with Dietzia sp. in the presence of xylene with 4.33 mg C/dm3 at the end of the process, followed by toluene with a level of 5.07 mg C/dm3 nd 5.60 mg C/dm3 in the presence of Vibrio alginolyticus. The lowest degradation rate was obtained in the presence of benzene with Dietzia sp. with 15 mg C/dm3 compared to the control, which was 27 mg C/dm3 at the beginning of growth. The results obtained showed that both selected strains assimilated the monoaromatics tested and could be used for the bioremediation of the polluted littoral.

Aluminium recycling is one of currently growing industries in Indonesia. Abundant amounts of aluminium waste leads to the emergence of new industries. The waste produced from this kind of industry is not well processed yet. Bioremediation using isolated indigenous bacteria is one of the best options from treating the aluminium recycling wastewater. Since biological processes are closely related to the bacterial growth conditions, it is important to understand the effect of pH and aluminium exposure to bacteria. Six potential bacteria strains were obtained from isolation. Vibrio alginolyticus and Brochothrix thermosphacta were shown to be resistant to the aluminium exposure, as well as the acidic conditions. Both types of bacteria were able to survive on acid medium with pH 5. The higher the concentration of aluminium, the slower bacterial growth rate achieved. The MIC value of aluminium for Vibrio alginolyticus was 425 mg/l, Brochothrix thermosphacta was 325 mg/l and Pseudomonas aeruginosa was 200 mg/l.
