“…According to the procedures described by Mudryk et al (2015) in order to determine Aeromonas abundance in the collected samples of water, these samples were diluted with sterile phosphate -buffered saline to reach final concentration ranging from 10 −1 to 10 −3 . Diluted water samples were filtered through a 0.45 -μm pore size, 47 mm -diameter membrane filters (Whatman ME 25/31 ST).…”

Abundance and antibiotic resistance of bacteria of the genus Aeromonas isolated from the water of three carp ponds were studied. The number of those bacteria differed between the studied ponds, sites and season. The results of the present study showed that planktonic Aeromonas inhabiting those ponds strongly differed in the resistance level to tested antibiotics. These microorganisms were the most resistant to amoxicillin, ampicillin, clindamycin and penicillin. However, all isolates Aeromonas were susceptible to gentamycin and streptomycin. Majority of bacterial strains were characterized by resistance to 4-6 of the 12 antibiotics tested. Bacterial resistance to antibiotics depended on their chemical structure. Aeromonas strains isolated from the studied ponds were the most resistant to β-lactam and lincosamides antibiotics, while the most susceptible to aminoglycosides, chloramphenicols and fluoroquinolones.

“…Examples include MRSA (methicillin-resistant Staphylococcus aureus) which has been detected in correlation with the quality of water and sand, showing a relationship with beach-user overcrowding, the concentration of other microorganisms, the presence of yeasts from human origin, as well as water temperature (Papadakis et al, 1997;Plano et al, 2011;Roberts et al, 2013). Mudryk et al (2013) showed that Vibrio species inhabiting sand were more resistant to antibiotics than those isolated from seawater; in addition, more than 90% of planktonic and benthic Vibrio-like bacteria could present multiple antibiotic resistance. Also multidrug resistant Enterococcus faecium from beach sand were identified with similar features to those from clinical human isolates (Heikens et al, 2008) indicating that enterococci can be included in the monitoring of sand, with the respective characterization of antibiotic resistance and virulence factors (Pinto et al, 2012a, b).…”

Beach sand and the potential for infectious disease transmission: observations and recommendations

Recent studies suggest that sand can serve as a vehicle for exposure of humans to pathogens at beach sites, resulting in increased health risks. Sampling for microorganisms in sand should therefore be considered for inclusion in regulatory programmes aimed at protecting recreational beach users from infectious disease. Here, we review the literature on pathogen levels in beach sand, and their potential for affecting human health. In an effort to provide specific recommendations for sand sampling programmes, we outline published guidelines for beach monitoring programmes, which are currently focused exclusively on measuring microbial levels in water. We also provide background on spatial distribution and temporal characteristics of microbes in sand, as these factors influence sampling programmes. First steps toward establishing a sand sampling programme include identifying appropriate beach sites and use of initial sanitary assessments to refine site selection. A tiered approach is recommended for monitoring. This approach would include the analysis of samples from many sites for faecal indicator organisms and other conventional analytes, while testing for specific pathogens and unconventional indicators is reserved for high-risk sites. Given the diversity of microbes found in sand, studies are urgently needed to identify the most significant aetiological agent of disease and to relate microbial measurements in sand to human health risk.

“…Vibrio -like bacteria were widespread in wet and dry sand at a marine beach on the Baltic Sea (Mudryk et al 2013), with many isolates showing antibiotic resistance that was considered a possible public health threat. Elmanama et al (2005) detected Vibrio in 29/130 (22%) of sand samples from the swash zone at marine beaches along the Israeli coast.…”

SUMMARY Beach sand is a habitat that supports many microbes, including viruses, bacteria, fungi and protozoa (micropsammon). The apparently inhospitable conditions of beach sand environments belie the thriving communities found there. Physical factors, such as water availability and protection from insolation; biological factors, such as competition, predation, and biofilm formation; and nutrient availability all contribute to the characteristics of the micropsammon. Sand microbial communities include autochthonous species/phylotypes indigenous to the environment. Allochthonous microbes, including fecal indicator bacteria (FIB) and waterborne pathogens, are deposited via waves, runoff, air, or animals. The fate of these microbes ranges from death, to transient persistence and/or replication, to establishment of thriving populations (naturalization) and integration in the autochthonous community. Transport of the micropsammon within the habitat occurs both horizontally across the beach, and vertically from the sand surface and ground water table, as well as at various scales including interstitial flow within sand pores, sediment transport for particle-associated microbes, and the large-scale processes of wave action and terrestrial runoff. The concept of beach sand as a microbial habitat and reservoir of FIB and pathogens has begun to influence our thinking about human health effects associated with sand exposure and recreational water use. A variety of pathogens have been reported from beach sands, and recent epidemiology studies have found some evidence of health risks associated with sand exposure. Persistent or replicating populations of FIB and enteric pathogens have consequences for watershed/beach management strategies and regulatory standards for safe beaches. This review summarizes our understanding of the community structure, ecology, fate, transport, and public health implications of microbes in beach sand. It concludes with recommendations for future work in this vastly under-studied area.
