Introduction The surface water bodies are affected by effluents containing pollutants from wastewater treatment plants, storm water overflows and run-off from non-point sources like agricultural land and urban city surfaces. This relates to land-based sources occasioned by run off at wastewater treatment plants rivers (Yang et al., 2011) like in China, where the Yangtze River is heavily affected by organic pollutants (Yang et al., 2008). This also affect the eThekwini Municipality, Kwazulu-Natal Province, South Africa, where impact of wastewater constitute public health importance are residual NSC 652287 (RAbs) (a.k.a antibiotic residue), antibiotic resistance genes (ARGs), antibiotic resistant bacteria (ARB) or multiple antimicrobial resistant bacteria (MARB) (Li et al., 2011a, Li et al., 2011b; Agunbiade and Moodley, 2014; Adegoke et al., 2016). Despite the public health importance of the RAbs, ARGs and the emergence of ARB in aquatic microbiomes, very little attention has been accorded to this research area in South Africa. Supplementary research report from other parts of the globes were therefore also reviewed related to the effect of RAbs, ARGs and ARB in water catchment on other water related applications in Southern African countries as well as a few other countries of the world.
Origin and effect of residual antibiotics, RAs and antibiotic resistance genes (ARGs) in surface water
Fate of ARB, ARGs, RAs in surface water Antibiotics are now ubiquitous as most systems are not equipped to trap them within different compartments of the environment. If there have been improved sewer system with automatic nano-devices to track and remove RAbs, the quantity reaching the receiving water bodies, if any at all, would be minimal. In the same way, RAbs which have been reported in the drinking water (Yang et al., 2011; Kim and Carlson, 2007; Barnes et al., 2008; Ye et al., 2007; Xu et al., 2007a, Xu et al., 2007b) would not have reached this level. Meanwhile, Persistence of RAbs in surface water may lead to bioaccumulation in aquatic microbiota (Baguer et al., 2000), aquatic plants and animals.
Mitigating the risk of exposure to RAbs, ARGs and ARB All along, exposure pathways and the effects of exposure to the RA have been discussed. The effects which include selection for ARGs, bioaccumulation and toxicity. Global action plan on antimicrobial resistance by the WHO (2015) laid down 5 focal approaches in addressing the human risk associated with RAbs. These include awareness creation through education, communication and training; strengthening the knowledge and evidence base through surveillance and research (this make this review of very high importance); reducing the incidence of infection through sanitation, hygiene and infection control measures; optimizing the use of antimicrobial medicines in human and animal health; and to develop economic case for sustainable investment with respect to the needs of individual countries.
Conclusion
Introduction The use of antibiotics in treating respiratory tract infections is common in medical practice, even in cases where viral infections are most likely. In general, antibiotic therapy is not recommended in initial treatment for upper respiratory tract infections (URIs); on the contrary, avoidance of prescribing antibiotics in these patients is encouraged, largely to prevent antibiotic resistance. In chronic rhinosinusitis, which adversely influences smell function in approximately three-quarters of patients, bacterial infection or colonization may directly induce inflammation or serve as a disease modifier of a preexisting inflammatory state. Therefore, antibiotic therapy is generally indicated to lower bacterial burden in such cases. A standard classification of antibiotics differentiates bactericidal antibiotics, which specifically kill bacteria, from bacteriostatic antibiotics, which impede bacterial growth. However, overlap exists between these two classes of antibiotics. While bactericidal antibiotics strongly and directly attack bacteria, the milder bacteriostatic antibiotics rely on phagocytosis and intracellular killing. Ocampo et al quantified death rates of both these classes of antibiotics and showed a substantial increase in killing rates for bactericidal antibiotics compared to those of bacteriostatic antibiotics. Although Nemeth et al found minimal differentiation of efficacy between bactericidal and bacteriostatic antibiotics for abdominal infections, soft tissue infections, and pneumonia, differentiation has not been established for URIs that impact olfactory function. Importantly, interactions between viruses and bacteria are known to occur within the upper respiratory tract, decreasing or increasing the potency of some antibiotics in complex microbial communities. In addition to anti-bacterial and anti-inflammatory effects, the bacteriostatic antibiotic minocycline has anti-apoptotic effects, delaying, for example, photoreceptor degeneration in the retina of the Prph2Rd2/Rd2 (rds) mouse.
