“…Antibiotics have been clearly detected in wastewater treatment facilities [73], but they are only partially eliminated during the sewage-treatment process [60,65]. Some are subsequently released via the contaminated effluent into the aquatic environment [60,64,[74][75][76][77] where, they are probably slowly transformed by biological and physical processes [78]. Resistant bacteria bred in the human gut can also enter the environment via sewage.…”

Antibiotic resistant bacteria have become increasingly widespread in the environment and their prevalence is a serious potential problem for human health. The rise and spread of this resistance is primarily due to the overuse of antibiotics in clinical therapeutics and as growth promoters for livestock. Overuse undermines the usefulness of antibiotics by giving a selective advantage to microbes that are resistant. The problem has been exacerbated by the emergence of bacteria that are resistant to multiple antibiotics and by the ability of these resistance determinants to spread between different bacteria via horizontal gene transfer. Such transfer can, for example, take place extensively in the digestive tract of domestic animals and aquatic environments, which can become reservoirs of multiple antibiotic resistant bacteria (MARB) and these sources contribute eventually to spread of antibiotic resistance to humans

“…Animals from the wild are exposed to antibiotic residues and bacteria with antibiotic resistance genes and consequently multiple antibiotic resistances have been found in almost all species of bacteria that inhabit humans, domestic animals and wildlife. Antibiotic-resistant bacteria from sewage effluents have been found to contaminate underground water and this has had a great impact on terrestrial and aquatic wild life [2,[32][33][34][35][36]. Antibiotic-resistance in the aquatic environment has received little attention, despite the fact it is a major problem, with large numbers of resistant bacteria being found in these ecosystems.…”

“…The overuse of antibiotics, agriculture runoff and coastal development has resulted in an increase in antibiotic-resistant bacteria isolated from marine habitats. Unfortunately, the coastal environment has been used as a dumping ground for sewage and other waste products [36]. As a result, the environment has become a reservoir for resistant bacteria and provides a return path for antibiotic resistance genes in bacteria that can infect both humans and animals [37].…”

“…Microbial isolates from cloacae of the loggerhead turtle (Carettacaretta), had similar high level of MARB [38]. MARB were isolated from eggs and oviductal fluid, an indication of contaminated effluents encountered by the sea turtles during migration and in the feeding areas near their nesting grounds [24,36,38,40]. Antibiotic resistant bacteria are also associated with aquaculture.…”

Multiple antibiotic resistant bacteria (MARB) and antimicrobial drugs enter the environment via wastewater, especially from hospitals and pharmaceutical plants, and through agricultural runoff, leading to contamination of surface and groundwater. This is a serious problem in arid regions such as Oman where wastewater is recycled for irrigation and recharging aquifers. Treatment with chlorine does not completely remove bacteria from wastewater or prevent their re-growth in downstream distribution systems. MARB can infect humans via contaminated food and drinking water, or directly from the environment. Agricultural runoff and sewage, either treated or untreated, are also the main sources of MARB in coastal seawater. It is necessary to use antibiotics more prudently in medicine, treat wastewater more effectively, eliminate the discharge of untreated waste into the environment, and curtail the profligate use of antibiotics as growth promoters for livestock.

Serum from Kemp's ridley sea turtles Lepidochelys kempii and loggerhead sea turtles Caretta caretta was collected during summer in 2011, 2012, and 2013. Serum immunoglobulin Y (IgY) recognition of lysate proteins from nine bacterial species and whole bacterium-specific IgY titers to these pathogens were quantified. Serum and purified IgY recognized proteins of all bacteria, with protein recognition for some species being more pronounced than others. Circulating IgY titers against Vibrio vulnificus, V. anguillarum, Erysipelothrix rhusiopathiae, and Brevundimonas vesicularis changed over the years in Kemp's ridley sea turtles, while IgY titers against V. vulnificus, Escherichia coli, V. parahaemolyticus, B. vesicularis, and Mycobacterium marinum were different in loggerhead sea turtles. Serum lysozyme activity was constant for loggerhead sea turtles over the 3 years, while activity in Kemp's ridley sea turtles was lower in 2011 and 2012 than in 2013. Blood packed cell volume, glucose, and serum protein levels were comparable to those of healthy sea turtles in previous studies; therefore, this study provides baseline information on antibody responses in healthy wild sea turtles.
