“…The isolated Coliform bacteria and the isolated non-hemolytic Streptococci showed mono-resistance to ceftriaxone and ampicillin, respectively. These findings accord with those published elsewhere, showing high rates of antibiotic resistance to airborne Staphylococci species and Gram-negative bacilli [ 17 , 27 ]. The study in indoor sites of a university in Ghana also found high rates of antibiotic resistance in airborne bacteria that included both Gram-positive cocci and Gram-negative bacilli [ 10 ].…”

“…We also did not collect and analyze ambient air samples at different seasons of the year. Other studies have found seasonal variation in the bacterial count and antibiotic resistance profiles [17,19,20]. We had planned to do sample collection at different times from 2020 onwards and in different seasons.…”

“…For example, a study in an urban area of Pakistan found antibiotic-resistant airborne bacteria in a number of roadside sites in both industrial and residential areas. [ 17 ]. Gao et al (2016) found a strong positive relationship between airborne bacterial concentrations and population density, human activity and road traffic movement, all of which characterize roadside sites [ 18 ].…”

Bacteria and Their Antibiotic Resistance Profiles in Ambient Air in Accra, Ghana, February 2020: A Cross-Sectional Study

Inappropriate use of antibiotics has led to the presence of antibiotic-resistant bacteria in ambient air. There is no published information about the presence and resistance profiles of bacteria in ambient air in Ghana. We evaluated the presence and antibiotic resistance profiles of selected bacterial, environmental and meteorological characteristics and airborne bacterial counts in 12 active air quality monitoring sites (seven roadside, two industrial and three residential) in Accra in February 2020. Roadside sites had the highest median temperature, relative humidity, wind speed and PM10 concentrations, and median airborne bacterial counts in roadside sites (115,000 CFU/m3) were higher compared with industrial (35,150 CFU/m3) and residential sites (1210 CFU/m3). Bacillus species were isolated in all samples and none were antibiotic resistant. There were, however, Pseudomonas aeruginosa, Escherichia coli, Pseudomonas species, non-hemolytic Streptococci, Coliforms and Staphylococci species, of which six (50%) showed mono-resistance or multidrug resistance to four antibiotics (penicillin, ampicillin, ciprofloxacin and ceftriaxone). There was a positive correlation between PM10 concentrations and airborne bacterial counts (rs = 0.72), but no correlations were found between PM10 concentrations and the pathogenic bacteria nor their antibiotic resistance. We call for the expansion of surveillance of ambient air to other cities of Ghana to obtain nationally representative information.

“…Although there are significantly fewer atmospheric microorganisms than there are in the oceans and in the soil, there is still a large enough number of bacteria, fungi, viruses, toxins, endotoxins, pollens, metabolites, or any other biological materials that can affect the atmosphere (1). In urban areas, the vehicular intensity adds to dust suspension with the subsequent addition of bioaerosols which varies greatly at different sites due to different point sources.…”

The emergence of multiple antibiotic resistant strains in the environment, particularly in a densely populated market is a problem to the infection management. The prevalence of antibiotic- resistant airborne bacteria was examined in five different outdoor markets in Ado Ekiti, Ekiti State, Nigeria. The sample collection was taken between 3-5pm when activities at the market place were at the peak. The bacteria isolates were identified and their antibiotic susceptibility to fourteen different antibiotics was carried out. Six genera of bacteria were recovered, Staphylococcus (16.7%), Escherichia (18.6%), Pseudomonas (21.6%), Enterococcus (19.6%), Salmonella (10.8 %) and Klebsiella (12.7%). The airborne isolates showed the highest resistance to Pefloxacin (52.3%), followed by Augumentin (44.7%). The lowest resistance was to Erythromycin (5.8%). All of Salmonellae typhimurium, and Escherichia coli were multiple antibiotic resistant (MAR), while a great percentage of otherisolates were also MAR (Staphylococcus aureus (88.3%), Pseudomonas aeruginosa (90.9%), Klebsiella pneumoniae (92.3%), and Enterococcus spp (85%). These results show that the air in the outdoor markets studied was highly contaminated with a great diversity of MAR bacteria. The findings of this study will be helpful in the intervention of health officials and policy makers in decision making towards the effective control of infections caused by the airborne bacteria in the outdoor markets.

“…Enterococcus spp. and some air borne and food borne pathogenic bacteria at alarming stage (Bhatti et al, 2019;Richwagen et al, 2019;Chatham-Stephens et al, 2019;Mehboob and Abbas 2019;Naz & Pasha 2019;Irum et al, 2019). According to the published data, the mortality rate is about 0.7 million worldwide due to antimicrobial resistance pathogens, which will raise 10 million by 2050 (de Kraker et al, 2019) The data reported by Center of Disease and Control showed about 23,000 mortality rates due to infection caused by antimicrobial resistance annually (Lim et al, 2016).…”

The need of effective and economical antibiotics and antimicrobials has led to search for novel sources such as medicinal plants, fungi, archaea etc. In the present study, Daphne mucronata and Mallotus philippensis methanolic extracts were screened as antibacterial agents compared to some antibiotics against eight local isolates of human pathogenic bacteria. The susceptibility test was performed through well diffusion and disc diffusion method. Results reported that D. mucronata showed significant antibacterial activity against all the selected strains. The highest zones of inhibition of D. mucronata seed extract were recorded against, Providencia stuartii (20mm), Brucella abortus (19.3mm), Proteus vulgaris (19.3mm), Klebsiella pneumonia (19mm), followed by Pseudomonas aeruginosa (19mm), Enterobacter sakazaki (18.3mm), Escherichia coli (16.6mm) and Staphylococcus aureus (16.6mm). D. mucronata seed extract was reported as the most active against B. abortus (19.3mm), E. sakazaki (18.3mm), E. coli (16.6mm) and K. pneumoniae (19mm) when compared to Cefepime (8.1mm) and Ciprofloxacin (14.2mm). However, D. mucronata methanolic seed extract showed about similar antibacterial activity against P. vulgaris (19.3mm), P. stuartii (20mm), P. aeruginosa (19mm) and S. aureus (18.7mm), compared to the following antibiotics Cefepime (19.3mm) Ciprofloxacin (21mm), Moxifloxacin (21mm) and Ceftriaxone (20mm). On the other hand, M. philippensis showed insignificant antibacterial activity against the selected bacterial strains, but not significant compared to selected antibiotics. As conclusion, D. mucronata extract was considered as high potential antibacterial and recommend to be used as novel and economical source of effective antibacterial agent to combat against h u m a n p a t h o g e n i c b a c t e r i a .
