This study aimed to determine the bacterial species colonizing the nasal and oropharyngeal mucosa of fuel workers in Central Riyadh, Saudi Arabia on a microbiological and molecular level.
Throat and nasal swab samples were obtained from 29 fuel station attendants in the period of time extending from March to May 2014 in Riyadh, Saudi Arabia.
Microbiological identification techniques were utilized to identify the bacterial species isolated.
Antibiotic sensitivity was assessed for each of the bacterial isolates.
Molecular identification techniques based on PCR analysis of specific genomic sequences was conducted and was the basis on which phylogeny representation was done for 10 randomly selected samples of the isolates.
Blood was drawn and a complete blood count was conducted to note the hematological indices for each of the study participants.
Nineteen bacterial species were isolated from both the nasal cavity and the oropharynx including Streptococcus thoraltensis, alpha-hemolytic streptococci, Staphylococcus hominis, coagulase-negative staphylococci, Leuconostoc mesenteroides, Erysipelothrix rhusiopathiae and several others.
We found 100 % sensitivity of the isolates to ciprofloxacin, cefuroxime and gentamicin.
Whereas cefotaxime and azithromycin posted sensitivities of 85.7 % and 91.4 %, respectively.
Low sensitivities (<60 % sensitivity) to the antibiotics ampicillin, erythromycin, clarithromycin and norfloxacin were observed.
Ninety-seven percent similarity to the microbial bank species was noted when the isolates were compared to it.
Most hematological indices recorded were within the normal range.
In conclusion, exposure to toxic fumes and compounds within fuel products may be a contributing factor to bacterial colonization of the respiratory tract in fuel workers.
