“…This bacterial range is found to be lower as compared to the data from the present study. A study by Mudryk et al (2014) from the coastal Baltic Sea showed the counts of Aeromonas to be higher as compared to Pseudomonas and E. coli, whereas in the present study the highest numbers were seen for Pseudomonas counts. When studies from the Indian coast are concerned regarding indicator and pathogenic bacteria, the East Coast (off Chennai) showed a higher abundance of total viable counts, and total coliforms as compared to the West Coast of India (off Kerala) (Sudhanandh et al, 2012;Vignesh et al, 2012).…”

Increasing urbanization and industrialization of the Visakhapatnam region have brought domestic sewage and industrial wastewater discharge into the coastal ocean. This study tries to look at the quantitative abundance of the indicator and pathogenic bacteria and their antibiotic susceptibility. As part of this study, both surface and subsurface water samples were collected from ten different regions (147 stations; 294 samples) which included 12 industrial discharge points, surrounding stations and two harbours from the coast of Pydibheemavaram to Tuni. Physicochemical parameters like salinity, temperature, uorescence, pH, total suspended matter, nutrients, chlorophyll-a, and dissolved oxygen of the water showed a difference from one region to other. We noticed the presence of indicator (Escherichia coli and Enterococcus faecalis) and pathogenic (Aeromonas hydrophila, Klebsiella pneumoniae, Proteus mirabilis, Pseudomonas aeruginosa, Salmonella and Shigella, Vibrio cholera and Vibrio parahaemolyticus) bacteria among the samples. Waters from the near harbour and Visakhapatnam steel plant showed lower bacterial load where there is no direct input from industries to the coastal water. Samples collected during the industrial discharge period had a higher bacterial load including E. coli. Enteric bacteria were found in higher numbers at most of the stations with some isolates being resistant to multiple antibiotics with higher antibiotic resistance (AR) and multiple antibiotic resistance (MAR) indexes compared with the other coastal water habitats in the Bay of Bengal. The occurrence of these bacteria above the standard limits and with multiple antibiotic resistance in the study region may pose a potential threat to the local inhabitants and can create an alarming situation in the coastal waters in the study region.

“…This means that Aeromonas are able to detoxicate those pharmaceutical organic compounds and according to Radu et al (2003) the high level of multiple resistance may arise from selective pressure due to the indiscriminate use of antibiotics. Adaptive responses of bacterial communities to several antibiotics noted in the present study may presumably re ect the history of antibiotics application in the studied ponds (Mudryk et al 2014). Most classes of antibiotics that are approved for human and animal use are introduced into water basins ( Ecconomou and Gouisa 2015; Kim et al 2015).…”

“…Those inhabiting the in ow region were resistant to nearly all tested antibiotics compared to bacteria inhabiting the out ow region of the studied water bodies. Also Mudryk et al (2014) and Cisar et al (2014) in their research documented that bacteria that differed in antibiotic resistance inhabited different parts of the water basins.…”

The diversity and antibiotic resistance of the genus Aeromonas were studied in the inflow region and outflow region in three carp ponds of a commercial fish farm. The collected data indicated that the abundance of Aeromonas differed among the research water basins, regions and seasons. The results of the present study showed that Aeromonas inhabiting the water of the studied ponds strongly differed in the resistance level to tested antibiotics. This genus of bacteria was the most resistant to amoxicillin, ampicillin, clindamycin and penicillin and susceptible to streptomycin. The Aeromonas bacteria inhabiting the inflow were more resistant to tested antibiotics than those inhabiting the outflow of the studied ponds. Results of this study showed that multiple antibiotic resistance was observed among Aeromonas isolated from studied water basins which indicates the pollution of this environment with antibiotic substances. Aeromonas inhabiting the inflow and outflow regions of studied three carp ponds show different level resistence to antibiotics belonging to the different classes.

“…These were then shaken for 1 minute to dislodge any bacteria present. 16 With the aid of inoculating loops, the inocula were transferred unto petri dishes containing the respective media. Oxoid UTI Chromogenic Agar (clear) and Uriselect 4 were used for presumptive identification of bacteria such as E. coli, Enterococcus faecalis , Pseudomonas aeruginosa , and Staphylococcus aureus .…”

Background: Bacteria are ubiquitous in the marine environment. Increasing concern for human health has led to growing interest in contamination on public beaches. The presence of pathogenic microorganisms originating from anthropogenic activities such as defecation and disposal of sewage on beaches are of special concern. In this study, presence of pathogenic bacteria and bacterial load in beach zones and point sources were investigated. Methods: Sand core samples from the subtidal zone, intertidal zone, supratidal zone and point sources from 5 beaches in Accra, Ghana, were collected and analysed. Total aerobic, coliform and Escherichia ( E. coli) counts were determined for each zone in the respective beaches. Bacteria isolates were presumptively identified using biochemical tests and confirmed with MALDI-TOF MS. Results: Mean total aerobic count and total coliform counts ranged from 2.10 to 3.01 log CFU/g and 0.29 to 2.18 log CFU/g respectively while E. coli counts ranged from 0.12 to 1.71 log CFU/g for the beaches. Total aerobic count from point sources was 2.4-folds higher than the subtidal zone while total coliform counts were 5-folds higher in the point sources compared to the supratidal zone. Point sources had 10 times ( P = .0016) more E. coli counts as compared to the subtidal zone. Isolates recovered (n = 35) belonged to 10 bacteria genera. These were Bacillus spp. (25.7%), Acinetobacter spp. (14.3%), Aeromonas spp. (14.3%), Klebsiella pneumoniae (14.3%), Aerococcus viridans (8.6%), Staphylococcus spp. (8.6%), Shewanella profunda (5.7%), Rheinheimera soli (2.9%), Pseudomonas aeruginosa (2.9%), and Exiguobacterium aurantiacum (2.9%). Conclusion: Point sources are major contributors to contamination on beaches. The presence of potentially pathogenic bacteria in beach sand could be a public health risk. Sensitization on cleanliness in the marine environment including beaches in Ghana is needed to enhance public health and safety.
