Abstract: Since oxacillin is the first-choice drug in the treatment of methicillin-susceptible Staphylococcus aureus infections, correct assessment of oxacillin susceptibility is mandatory. METHODS: One hundred and fifty-six S.aureus strains have been used to evaluate the accuracy of disk diffusion method (1 μg oxacillin disk and 30 μg cefoxitin disk), detection of minimum inhibitory concentration of oxacillin (E-test), and a latex-agglutination test for detection of PBP2a compared with detection of mecA gene by a real-time PCR technique as gold standard. RESULTS: The mecA gene was detected in 68 strains. Sensitivities of the evaluated methods were 98.5%, 100%, and 100%, while specificities were 100% for all three of them. CONCLUSIONS: Accuracy of phenotypic methods for assessment of oxacillin resistance approaches that of detection of mecA for S.aureus isolates

Abstract: Romania is one of the countries with the highest prevalence of methicillin-resistant Staphylococcus aureus (MRSA) in the world. To obtain data on affiliation of MRSA to strains and clonal complexes and on the population of methicillin susceptible S. aureus (MSSA), clinical isolates from bloodstream infections, skin and soft tissue infections as well as from screening swabs were collected at hospitals in Ia?i, a city in the North-Eastern part of Romania. Isolates were characterised by microarray hybridisation. Nearly half of all isolates (47%), and about one third (34%) of bloodstream isolates were MRSA. The prevalence of the Panton-Valentine leukocidin (PVL) was also high (31% among MRSA, 14% among MSSA). The most common MRSA strain was a PVL-negative CC1-MRSA-IV that might have emerged locally, as a related MSSA was also common. PVL-positive CC8-MRSA-IV (“USA300”) and PVL-negative ST239-like MRSA-III were also frequently found while other MRSA strains were only sporadically detected. Among MSSA, PVL-positive CC121 as well as PVL-negative CC1, CC22 and CC45 predominated. Although this study provides only a snapshot of S. aureus/MRSA epidemiology in Romania, it confirms the high burden of MRSA and PVL on Romanian healthcare settings.

Abstract: Zimbabweans continue to experience challenges in combating communicable diseases such as tuberculosis, diarrheal diseases, and HIV/AIDS. The country’s health sector decentralisation implementation is moving at a snail’s speed, triggering complaints of unsatisfactory service delivery at rural health centres. The study examined the impact of political reforms in improving quality health services in Shamva District. The identified political reforms were decentralisation and the second republic that emerged in November 2018 that embraced the 100-day plans approach, civil service reform agenda, development of transitional stabilisation plan and vision 2030 agenda. The study was guided by interpretive and critical post-modernist paradigms. Qualitative methodology was utilised; key informant interviews, focus group discussion and desk reviews were data generation tools that were utilised. The data generated were analysed using grounded theory. The key findings are that decentralisation enabled district health officials to interact with communities through social accountability strategies such as community scorecard, results-based financing and village health worker model that is implemented in Shamva District by Civil Society Organisations. The second republic political reforms enforced the user fee policy in the health sector and focused on improving primary health care. The political reforms led to improved health rights knowledge of communities and quality health services in Shamva District. The study concluded that lack of continuous funding and sustainable plans led to the reversal of positive results that were brought in by the political reforms. The major recommendation is that government should understand that service delivery is not poor by accident; rather it is a symptom of the

Journal of Environmental Protection (JEP) , 2016, DOI: 10.4236/jep.2016.77094

Metallo-β-Lactamases (MBLs) and Extended Spectrum β-Lactamses (ESBLs) have emerged world-wide as a significant source of β-lactam resistance. The emergence of MBLs and ESBLs encoded on plasmids among Gram-negative pathogens in hospital dumpsites was investigated. Soils of different government and private hospitals were collected and processed following standard bacteriological techniques. Antimicrobial susceptibility testing was carried out by the disk-diffusion technique using Ceftazidime (30 μg), Cefuroxime (30 μg), Cefotaxime (30 μg), Cefixime (5 μg), Trimethprim-sulfamethoxazole (25 μg), Gentamycin (100 μg) Amoxicillin-Clavunalate (30 μg), Ciprofloxacin (5 μg), Ofloxacin (5 μg), Nitrofurantoin (300 μg) and Imipenem (10 μg). The role of plasmids in resistance was evaluated by subjecting isolates to curing using Sodium Dodecyl Sulfate (SDS). ESBLs production by Double-Disk Synergy Test (DDST) was carried out. Isolates resistant to Imipenem were subjected to a confirmatory test using Modified Hodge’s test and to MBLs production by DDST. Eighty-two Gram-negative isolates comprising of 32 (39.02%) Escherichia coli, 20 (24.39%) Serratia marcescens, 14 (17.07%) Klebsiella pneumonia, 10 (12.28%) Proteus mirabilis and 6 (7.32%) Enterobacter aerogenes were obtained. Susceptibility results revealed a 100% resistance of all isolates to Ceftazidime, Cefuroxime, Cefixime, Amoxycillin-clavulanate and Cefotaxime. A total of 66 (80.48%) isolates harboured plasmids out of which 26 (31.71%) isolates were ESBL producers. MBLs production was observed in 8 (25.00%) E. coli, 2 (2.41%) Klebsiella pneumonia and 2 (2.41%) Proteus mirabilis isolates. All MBLs producing isolates were ESBLs producers. The finding of highly resistant isolates producing ESBLs and MBLs in a hospital environment is quite disturbing and should be addressed urgently.

Abstract: Untreated Hospital wastewater piped into septic tanks contributes to the spread of antibiotic resistance in developing countries. This study was conducted to determine the resistant profile, and Extended Spectrum Beta-Lactamases (ESBLs) production in isolates from hospital waste water, of 2 hospitals in Delta State, Nigeria. A total of 147 organisms were isolated from 32 waste water samples. One hundred and twenty three isolates were Gram negative and 24 were Gram positive. Escherichia coli was the most prevalent in the two locations. Antimicrobial susceptibility by standard disk diffusion method was performed. All isolates were resistant to 4 or more antimicrobial agents. Out of the 123 Gram negative Bacteria, 33 were pan drug resistant and were selected for plasmid curing, DNA extraction and phenotypic detection of ESBL. Transfer of resistant by broth mating technique was performed. Plasmid curing and extraction result indicated that isolates carried resistance on the plasmid and harboured similar multiple high molecular weight plasmids of 23.13 kb and 9.4 kb. ESBL production was detected in 15.15%. Transfer of resistant genes between ESBL producing and non-ESBL producing isolates was observed. Incidence of ESBL in untreated hospital waste water has public health implications. Therefore establishment of treatment plants in our hospital is paramount in achieving sustainable health.

Abstract: Nous nous sommes intéressés à la qualité de l’eau potable selon la législation interne STAS 1342/91, dans plusieurs stations de chemin de fer du nord-est de la Moldavie choisies aléatoirement : Banca, Crasna, Barnova, Vere ti et Gura Putnei. Nous avons pris en compte pour cette étude certains indicateurs chimiques de qualité, notamment des ions majeurs (chlorures/chlore libre résiduel, sulfates/sulfures, nitrates/nitrites) et des métaux (fer, cuivre, chrome). Pour chacun de ces indicateurs, les valeurs moyennes mesurées dans l’eau potable ont été comparées aux limites normales admises par la loi 311/2004. Nous avons ainsi identifié plusieurs cas où les valeurs de certains indicateurs susmentionnés dépassaient les limites maximales autorisées.
Chungará (Arica) , 2010, DOI: 10.4067/S0717-73562010000100031
Abstract: sixteenth century sources associate the notion of labour in the andes with that of enjoyment, while most colonial spaniards and modern anthropologists see it as obligatory, ignoring its ritual dimensions. generally speaking, western theorists of labour, whether marxist or not, link labour and production with alienation. drawing on her fieldwork experience, the author notes that there is no aymara word for labour in general. more important is the purpose and beneficiary of labour. andeans not only value labour aimed at strengthening their own social networks, but more specifically labour that benefits the community to which they belong. the andean ethic of labour therefore leads it to be considered as a blessing, in opposition to judaeo-christian ways of considering it as a curse.
Pensadoras de peso: o pensamento de Judith Butler e Adriana Cavarero
Guaraldo, Olivia;
Revista Estudos Feministas , 2007, DOI: 10.1590/S0104-026X2007000300010
Abstract: the work presents the standpoint of two important contemporary feminist philosophers, adriana cavarero and judith butler, on subjectivity and relationality, showing how both moved away from the specific feminism motif in order to deepen and broaden their reflection on politics and ethics. calling tradition into question, cavarero agrees neither with the metaphysical binary, nor with the post-modern impersonality, combining a feminist and the arendtian perspectives of the subjectivity based on relationality. contrary to cavarero's thought, though, under butler's deconstructionist standpoint language shapes body and identity. subjectivity is "trapped" into social norms and values. both butler and cavarero rethink subjectivity based on relationality, that is, displacing politics from the immune individual and reallocating it on the vulnerable individual in relation with the other and with the social rules and values imposed on them.
Evaluación de un Sistema Discontinuo de Biodigestión Anaerobia para el tratamiento de desechos avicolas
Revista de la Facultad de Ingeniería Universidad Central de Venezuela , 2005,
Abstract: in the present study, carried out in guanare (venezuela), in the period between november 1998 and march 1999, the application of an anaerobic digestion process in a discontinuous flow (batch) system was evaluated for the treatment of hen manure and rice hulls, with the purpose of stabilization, biogas production and pathogen control. the main biogas production (0,249 m3/m3d) was obtained with a combination of the evaluated materials, in a retention time of 60 days. in the bacteriological study, we found bacteria of the escherichia, proteus, enterobacter and klebsiella groups. salmonella was not found. the parasitological study reported ascaridia, trichostrongylus, heterakis and eimeria. among the conclusions reached, we emphasize that the anaerobic mesophilic process exercises scarce control over bacteria of the enterobacteriaceae group, and no control was observed over the parasite eggs found. therefore, further studies into these aspects is considered important, so as to find alternatives of control and recommendations for a safe handling of manure.
