“…The progressive rapid increase (growth) in the number of the identified indigenous bacteria in the contaminated sites in this study is an indication of the fact that the contaminated sites supported the growth of such bacteria, although with the help of the nutrient and Mac-Conkey agar, which was eventually very slow in the uncontaminated site (control site). The bacteria counts for both the nutrient and Mac-Conkey agar was similar to that reported by [23,19,24] but lower than that reported by [25]. This variation could be due to the differences in microbial ecology of the soil or characteristics of the experimental soil.…”

Microbial biodegradation of engine oil contaminated soil in Calabar Metropolis was studied for a period of six (6) months (January to June, 2017). The soil samples collected were ice boxed and taken to the laboratory for microbial, total hydrocarbon, total organic carbon and other physicochemical parameters analysis. A total of thirteen (13) indigenous bacteria species were identified in the soil of the sites analyzed during the study, which includes; Staphylococcus spp., Pseudomonas aeruginosa, Bacillus spp., E. coli, Enterococcus feacalis, Shigella spp., Arthrobacter spp., Alcaligen spp., Acinobacter spp., Azotobacter spp., Aeromonas spp., Xanthomonas spp. and Clostridium spp. The most abundant bacteria in the contaminated site was Staphylococcus spp. (65%) while the least Andem et al.; ASRJ, 2(1): 1-12, 2019; Article no.ASRJ.47089 2 bacteria count in the contaminated site was Clostridium spp. (9%). Staphylococcus spp. was the most abundant indigenous bacterial species and also the most effective biodegradation bacteria. The identified indigenous bacteria utilized the hydrocarbons, multiplied rapidly and then degraded the total hydrocarbon and total organic carbon more in the contaminated site compared to the control site. Site one recorded the highest bacteria count (927) while the least bacteria counts were recorded in the control site (81). The bacteria species showed its degradation and bioremediation capabilities prompting the need for its use in cleaning crude oil contaminated sites, due to the fact that it is cheap and not environmentally harmful.

“…Waste materials could be garbage, rubbish, yard waste, toxic waste and domestic refuse [1]. Municipal solid waste dump areas commonly referred to as waste dumpsites constitute environmental and public health hazards all over the world [2]. More so, human activities such as sewage treatment, plants and animal rendering, fermentation processes and agricultural activities do emit microorganisms into the air [3][4][5][6].…”

This study is to assess the microbiological quality and public health hazard associated with the air environment around waste dumpsites in Keffi, metropolis Nigeria was conducted. A total of 25 samples were collected from five different waste dumpsites around five different locations within the metropolis (Angwan Lambu, Keffi Main market, University Main campus and Nasarawa Road). Preliminary cultural, morphological, biochemical characteristics of the isolates revealed the following isolates, Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus, Proteus vulgaris, Bacillus spp, Micrococcus spp., Aspergillus niger, Alternaria spp., Penicillum spp., Mucor spp., Fusarium spp., Rhizopus stolonifer and Candida spp. The total bacterial counts from the air environments of these waste dumpsites ranged between 2.2-7.4 x 10 1 cfu/m 3 , while the total fungal counts ranged between 1.4-4.4 x 10 1 cfu/m 3. The susceptibility of the bacterial isolates against commonly used antibiotics tested showed varying degree of susceptibility and it is in the following decreasing order; Proteus vulgaris (93.3%) > Staphylococcus aureus (55.6%) > Micrococcus spp. (43.3%) > Pseudomonas aeruginosa (42.8%) > Bacillus spp. (41.2%) > Escherichia coli (30.8%). Health risk assessment indicates the presence of pathogenic bacteria and moulds with serious health risk to human within the environment due to the possibility of cross contamination of foods sold in the open. Consequently, there is the need to periodically monitor the number of microorganisms within the air of these environments using the established threshold stipulated for microbial concentrations in air.

“…Estes procedimentos devem anteceder à deposição final para presevar a saúde pública e ambiental. Estudos realizados por Bassey et al (2015), utilizando procedimentos microbiológicos padrão de detritos sólidos em decomposição, do lixiviado, do solo e do ar evidenciaram que as bactérias predominantes foram Escherichia coli, Chromobacterium spp, Staphylococcus spp., Salmonella spp Klebsiella spp. As altas contagens bacterianas associadas a estes achados são indicativas do risco elevado de infecções microbianas.…”

“…As bactérias patogênicas isoladas com maior frequência são dos gêneros Bacillus, Staphylococcus e Streptococcus, juntamente com números variados de outras bactérias patogênicas nosocomiais comuns, como Klebsiella, Salmonella, Proteus e Enterobacter (COKER et al, 2009). No entanto, diversos estudos evidenciaram que as espécies microbianas mais prevalentes nos RSS são Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Bacillus cereus, Lactobacillus spp., Staphylococcus spp., Micrococcus spp., Propionibacterium acnes, Enterobacter spp., leveduras (Candida albicans) e bolores (ALAGÖZ, KOCASOY, 2008;NASCIMENTO et al, 2009;PARK et al, 2009;BASSEY et al, 2015;CHAYB, KOZUSNY-ANDREANI, 2015;MARTINS et al, 2015).…”

Nesta pesquisa objetivou-se avaliar a viabilidade técnica da aplicação de ozônio como bactericida e fungicida em amostras de resíduos de serviços de saúde potencialmente infectantes. Foram determinados os micro-organismos presentes nos resíduos gerados em um hospital particular. Para realização das análises microbiológicas e o tratamento com ozônio o material foi particulado e homogeneizado. As análises microbiológicas foram realizadas antes e após a ozonização.Para os testes de desinfecção foram retirados 10,0g de amostra que foi submetida à ozonização por 5, 10, 15, 20 e 25 minutos com doses de 140,0; 280,0; 420,0; 560,0 e 700,0mg L-1 de ozônio, respectivamente. Verificou-se presença de mesófilos totais, coliformes totais e termotolerantes, Escherichia coli, Pseudomonas aeruginosa, Proteus spp., Staphylococcus aureus, Staphylococcus spp, Candida albicans e Rhizopus spp. O ozônio foi eficiente para eliminação de todos os micro-organismos em 20 minutos; nos primeiros cinco minutos de exposição ao gás verificou-se redução superior a 98%.Palavras-chave: Bactérias patogênicas.

USING OZONE GAS FOR DISINFECTION OF SOLID WASTE FROM HEALTH CARE SERVICES ABSTRACT: The aim of this research was to evaluate the technical viability of the application of ozone as bactericide and fungicide in samples of potentially infectious health services residues. The microorganisms present in the waste generated in a private hospital were determined. The material was particulated and homogenized to perform the microbiological analysis and to undergo ozone treatment. Microbiological analysis was performed before and after ozonization. For the disinfection tests, 10.0g of sample were removed and submitted to ozonization for 5, 10, 15, 20 and 25 minutes with 140,0; 280,0; 420,0; 560,0 and 700,0mg doses of L-1 of ozone, respectively. It was verified the presence of total mesophiles, total and thermotolerant coliforms, Escherichia coli, Pseudomonas aeruginosa, Proteus spp., Staphylococcus aureus, Staphylococcus spp, Candida albicans and Rhizopus spp. Ozone was efficient while eliminating all microorganisms in 20 minutes; in the first five minutes of gas exposure, the reduction was greater than 98%.Keywords: Pathogenic bacteria. Fungi. Ozonization.
