Pseudomonas aeruginosa and Bacillus sp. are ubiquitous in hospital wastewater discharges. The infections caused by P. aeruginosa become complicated, as they acquire the ability to resist many classes of antibiotics. Some strains of P. aeruginosa has been reported to survive for months on dry surfaces, and it can persist and grow in contaminated antimicrobial handwash containing triclosan, making it a critical concern for hospital staff [5]. Infections with Bacillus sp. are rare, but they are able to produce spores and grow haemolytically on blood agar plates (β-hemolysis). Gram-positive Bacilli can cause many types of infections and are spread to humans in a variety of ways [6,7]. Some of the frequently encountered species include B.
