“…P. pseudoalcaligenes, the most common species found, is often isolated from environmental samples and has also been also related to antibiotic resistance (Quinteira et al 2005). Resistant P. aeruginosa have been commonly found in hospital effluents (Fonseca et al 2005;Fuentefria et al 2008;Tuméo et al 2008;Yang et al 2009;Fuentefria et al 2011). It is important to consider the presence of resistant isolates from other Pseudomonas species, since they may represent a possible reservoir of resistance determinants in the hospital effluent, as shown by Koh et al (2004).…”

“…Studies have demonstrated that hospital effluents are highly selective environments and that they contribute to the high rates of resistant bacteria that are being discharged in the natural environment (MeirellesPereira et al 2002;Prado et al 2008;Yang et al 2009;Li et al 2009;Fuentefria et al 2011;Ferreira et al 2011). The increase of pathogenic bacteria resistant to beta-lactams has been of public health units concern all around the world, since the misuse of these drugs is strongly related to this process.…”

Pseudomonas aeruginosa (P. aeruginosa) has been found to be a common hospital acquired pathogen, responsible for several severe infections. The objective of this study was to describe the antibiotic resistance profile of P. aeruginosa strains from human sample. This descriptive study was carried out on 168 isolated strains of P. aeruginosa collected from January 2014 to December 2015 at the Pasteur Institute of Côte d'Ivoire. The strains identification was done according to the methods of conventional bacteriology. The antibiotic sensitivity tests were performed using the disc diffusion method in agar medium according to CA-SFM (Antibiogram committee of French society of microbiology) criteria. The serotyping of the strains was carried out by using the agglutination method slide test, with the aid of 4 specific polyvalent antisera. The most prevalent P. aeruginosa serotypes were O4 (24.4); O11 (14.6); and O6 (9.5%). The rate of antibiotic resistance to ticarcillin was 32.9%, ciprofloxacin 18.4%, ceftazidime 14.9%, Imipenem 11.3%, and amikacin 11.3%. Resistance to Imipenem was above 10% in an intensive care unit and in the pneumonology unit (PPH). Strains of O6 serotypes were the most multidrugresistant followed by O11 with respective rates of 31.2 and 28% MDR (Multidrug Resistance). P. aeruginsa are microorganism capable of developing mechanisms of complex resistance which makes it difficult to manage. The attention of hygiene rules and the rational use of antibiotics are very important in other to prevent the spread of MDR P. aeruginosa.

“…[1,2] Several studies have shown their incomplete removal during conventional wastewater treatment processes [3,4] and, therefore, the application of new and improved wastewater treatment technologies, including advanced oxidation processes (AOPs), is a necessary task. In the past decade, a number of research groups have dealt with the removal of various pharmaceuticals by AOPs.…”

“…In the past decade, a number of research groups have dealt with the removal of various pharmaceuticals by AOPs. [5][6][7][8][9] Amongst the various AOPs, photocatalysis has been widely investigated for the treatment of pharmaceuticals due to its capacity (1) to mineralize organic pollutants, (2) to utilize the solar radiation as the light source, thus reducing significantly electric power required and therefore saving treatment costs and (3) to operate without pH adjustment. [7] Klauson et al [10] and Elmolla and Chaudhuri [11] studied the application of photocatalysis to β-lactam antibiotics, concluding that degradations above 50% occur, associated with high removal of dissolved organic carbon (around 80%).…”

The photocatalytic degradation of an antibiotic, vancomycin B hydrochloride (VAN-B), has been investigated in aqueous suspensions of titanium dioxide (TiO2) by monitoring the change in its concentration as well as the production of ammonia and chlorides as a function of irradiation time. The removal of 50mg L(-1) VAN-B solution yields maximum concentrations of 2.45 and 2.53 mg N-NH3 L(-1) after 120 min of photocatalytic oxidation using 0.1 and 0.2 g TiO2 L(-1), respectively. When 0.2 g TiO2 L(-1) were applied up to 87% of the stoichiometric amount of chloride was reached within 120 min of irradiation, corresponding to 0.087 mmol L(-1). A set ofbioassays (Daphnia magna, Pseudokirchneriella subcapitata and Ceriodaphnia dubia) was performed to evaluate the potential detoxification of VAN-B and its by-products of oxidation under chronic and acute tests. The toxicity of the treated VAN-B samples varied during the oxidation, due to the formation of some intermediate products more toxic than VAN-B. Despite almost total removal of VAN-B that was achieved within 120 min of irradiation, a significant increase in toxicity was observed in chronic tests proving that the chronic assays are more appropriate than acute ones to detect the impact of by-products formed during the photocatalytic degradation of antibiotics.
