Advances in Microbiology (AiM) , 2012, DOI: 10.4236/aim.2012.23041
Abstract: This study has determined the portage of bacteria responsible for foodborne illness in the school canteen staff. 336 samples taken on the nose, mouth and hands were collected. Microbiological analyses were realized and several pathogenic bacterial strains were isolated from the vendors: Staphylococcus aureus (26/122), sulphite-reducing clostridia (14/122) and Escherichia coli (10/122). The food vendors in the school canteen may be the vectors of germs that cause food poisoning among young students.

Abstract: Introduction: To overcome the problems of periodic re-impregnation of mosquito nets and low rates of treatment, the commune of Aguegues was chosen to evaluate the effects of Olyset nets on malaria transmission and against An. gambiae. Methods: 87 old Olyset nets installed five years ago were identified in the village ‘Akpadon’. 10 untreated nets were installed in 10 structures of type “a bedroom and parlour” in the village ‘Akodji’. Four rooms without nets were identified in the village ‘Donoukpa’. Entomological and epidemiological evaluations were conducted during the May to October 2011. 24 sessions of capture or 2088 men-nights resulted in the capture of 30,608 mosquitoes. Results: The entrance of anopheles was significantly reduced in the village with Olyset nets. 45% of mosquitoes captured inside rooms with Olyset nets were found dead after 24 hrs of observation. Overall, parasitemia was very low in the treated village (4.52%). 18 (4.64%) cases of malaria fever were from Akpadon with 7.5% positive blade smear, 29 (10.98%) were from Akodji with 8.37% positive blade smear, and 80 (95.23%) come from Donoukpa with 38.09% positive blade smear. The Olyset nets and untreated net were adjusted hemoglobin levels. Conclusion: Olyset net had a very high knock down effect and is an alternative in malaria control

International Journal of Animal and Veterinary Advances , 2012,
Abstract: Bacteria are microorganisms involved in the digestion of foods by many animals. At the same time, some of them are pathogens causing serious diseases to the survival of animals that harbor them. It is therefore essential to identify the different species of bacteria in feed served to farm animals. The present study aims at identifying the bacteria in the fishmeal used for feeding imported chickens in Atlantic Department. Out of sixtyone (61) samples collected, twenty six (26) came from provender sites, sixteen (16) from wholesaling importers and nineteen (19) from imported chicken breeds. A total of twelve types of bacteria were identified: Staphylococcus, Klebsiella, Serratia spp, Actinomyces piogenes, Erysipelothrix spp, Citrobacter spp, Escherichia coli, Lysteria spp, Levinea spp, Salmonella spp, Bacillus spp, Providencia spp. Ten out of them, namely Staphylococcus spp, Klebsiella spp, Serratia spp, Actinomyces piogenes; Erysipelothrix spp, Escherichia coli, Levinea spp, Bacillus spp, Lysteria spp, Providencia spp were isolated from provender and five (5) bacteria: Staphylococcus spp, Klebsiella spp, Actinomyces piogenes; Lysteria spp; Levinea spp were found in fishmeal from wholesalers. Regarding the poultry farms, seven (7) bacteria out of twelve, Staphylococcus spp, Actinomyces piogenes, Citrobacter spp, Escherichia coli, Klebsiella spp, Levinea spp and Providencia spp were isolated from fishmeal. As for the two varieties of fishmeal used, it is clear that Klebsiella spp was more present in the Extra variety at a rate of 27.27%. On the other hand, the Valcru variety was contaminated with Staphylococcus spp at a rate of 18.18%. Therefore, it is essential to take into consideration hygienic measures.

Abstract: Vegetables are very important sources of protein and minerals. Some of them even have medicinal properties recognized traditionally. Despite the large number of studies carried out on various vegetables and vegetable crops, very few have scientifically explored the usefulness of S. macrocarpon. This study identified the main groups of chemicals and mineral elements to explain any medicinal or nutritional value. It has also identified some toxic elements contained in this vegetable. Phytochemical screening was carried out on the leaves and fruits of S. macrocarpon. Some mineral elements were determined by Atomic Absorption Spectrophotometry (sodium, potassium, calcium, magnesium) while protein, phosphorous, iron, copper, zinc and toxic metals (lead, cadmium) were determined by Molecular Absorption Spectrophotometry. Fat, ash, moisture and vitamins were sought. The study showed that the leaves of S. macrocarpon were more nutritious than fruits (P < 0.05). The high protein content of the leaves and fruit suggests an interesting nutritive property. The presence of chemical groups and toxic elements (lead, cadmium) in S. macrocarpon require that the consumption of vegetables should be as varied as possible and that the fruit may be consumed with caution. In addition, constraints about vegetable cultivation in Cotonou could lead to research findings that could help provide techniques for producing healthy vegetables.Vitamins A and K1 were found in both parts of this vegetable very rich in water while vitamin E has not been detected. S. macrocarpon also contains lipids at various levels.

Abstract: In order to assess the cement dust levels at the factory of the Beninese Cement Industry (BCI), at Xwlacodji, seven sampling stations (numbered 1 to 7) were set inside the industry and nine (numbered 8 to 16) were set around the factory in January, February, August and December. With the method of stainless steel plate according to NFX 43-007 AFNOR Standard, the different stations were monitored daily for dust collection all month long. The results revealed that the mean values of cement dusts inside BCI in g/m2/day ranged from 1.608 to 8.752 in January, from 1.13068 to 6.14924 in February, from 0.9654 to 5.2502 for August and from 1.7220 to 9.3620 for December. With regard to outside BCI, the mean values of dusts rose from 8.8760 to 18.9620 in December. The lowest mean values 3.2719 and 4.4124 were respectively recorded in February and August whereas the highest values 17.7309 and 18.9620 were respectively recorded in January and December. Our study revealed month variation in cement dust deposition with the highest values in December and January and the lowest values in February and August. It was observed that the content in cement dusts recorded outside the cement industry were extremely higher than those recorded inside the cement industry. The values in the present study have far exceeded all the international safety values (1 g/m2/day for AFNOR and 350 mg/m2/day TA-Luft) and could pose health hazards. Therefore protective measures are suggested to mitigate the risk of occupational hazards for the cement industrial workers.

Abstract: A study on the use of pesticides in market-gardening production was carried out on 108 market-gardeners in the rural city of Tori-Bossito in Southern Benin. The objective of the study was to characterize the potential risks of pesticides usage by farmers and the impacts on their health and on the environment. Two risk indexes were calculated for each pesticide: an environmental risk index (ERI) and a health risk index (HRI). First stage larva of the mosquito Aedes aegypti were used as bio-indicator for detecting insecticide residue in vegetable before their harvesting on the farms. The highest ERI were obtained for carbofuran, chlorpyriphos ethyl and endosulfan. Pesticide residues were found in 42% of the samples of leaves of eggplant, cucumber, amaranth and solanum. Vegetables growers used pesticides that may be highly hazardous and which were not registered in most cases. These situations could have unexpected consequences including the exposure of consumers to health hazards.

Abstract:

To evaluate lead and cadmium contamination in Moringa oleifera leaves powders marketed in Cotonou and health risks associated with its consumption, cross-sectional and analytical study were done from October 23th, 2012 to June 20th, 2013. Samples of Moringa powders were purchased at different outlets (health centers, supermarkets, pharmacy, etc.). Assays were performed by atomic absorption spectrophotometry after digestion according calcination method. Pb and Cd levels were compared with Codex Alimentarius standards, using the Student t test. Daily Exposure Doses (DDE) and Hazard Quotients (HQ) specific to each contaminant were calculated using a conventional method. Results revealed that the mean concentration of lead for all samples (1.526 mg/kg) exceeded of about 5.08 times the maximum allowable limit whereas cadmium levels (0.246 mg/kg) was not statistically higher than the standard. The highest concentrations of Pb and Cd are respectively 4.263 mg/kg and 0.354 mg/kg. Children are 2.3 to 3.8 times in greater danger than adults although all QD calculated are less than 1, reflecting that there is a low risk to consumers in general. For both metals, DJE specifically linked to the consumption of Moringa was less than 2% compared to other kinds of food intake. In conclusion, the current level of contamination (with lead and cadmium) of Moringa leaves powders marketed in Cotonou is not yet an alarming threat to consumers’ health. However, care must be taken to reduce chemical pollution especially soils where these plants grow.

Abstract: The Gulf Cooperation Council (GCC) countries approximately have 40% of world’s proven oil reserves and 21.7% of world’s known gas reserves. Low energy costs compiled with low taxation make it lucrative to foreign energy-intensive companies to operate in the region. Energy consumption in GCC has increased by 74% in the period between 2000 and 2010 and it is projected to increase by approximately 10% to 15% between 2010 and 2020. Embracing the general commitment by GCC states to reduce greenhouse gas emission (GHG) of United Nation Framework Convention on Climate Change (UNFCCC) has started the process of environmental awakening in the GCC countries due to its high vulnerability to the effects of climate change. This paper reviews the trends in shift to renewable energy with reference to GCC and also the co-benefits of investing in renewable energy. Solar plant and Building-Integrated Photo-Voltaic (BIPV) systems are the most invested projects. However in the long run, policies and strategies are needed to ensure the successful and larger implementation of mitigation objectives.
Population decline in the Delta caribou herd with reference to other Alaskan herds
Patrick Valkenburg et al.
Rangifer , 1996,
Abstract: After growing continuously for nearly 15 years, the Delta caribou herd began to decline in 1989. Most other Interior Alaskan herds also began declining. In the Delta herd, and in other herds, the declines were caused primarily by high summer mortality of calves and increased natural mortality of adult females. Other minor causes included increased winter mortality of calves, and reduced parturition rates of 3-year-old and older females. The decline in the Delta herd also coincided with increased wolf (Canis lupus) numbers, winters with deeper than normal snow, and warm summers. Mean body weight of annual samples of 10-month-old female calves was consistently low during the decline. Except in some of the smallest Interior Alaskan herds, we conclude that evidence for population regulation in Alaskan caribou is weak, and that herds are likely to fluctuate within a wide range of densities due to complex interactions of predation and weather. Unless wolf numbers are influenced by man, the size of a caribou herd in a given year is likely to be largely a function of its size during the previous population low and the number of years of favorable weather in the interim.

Abstract: Background Buruli ulcer (BU) is a neglected tropical disease caused by Mycobacterium ulcerans. Usually BU begins as a painless nodule, plaque or edema, ultimately developing into an ulcer. The high number of patients presenting with ulcers in an advanced stage is striking. Such late presentation will complicate treatment and have long-term disabilities as a consequence. The disease is mainly endemic in West Africa. The primary strategy for control of this disease is early detection using community village volunteers. Methodology/Principal Findings In this retrospective, observational study, information regarding Buruli ulcer patients that reported to one of the four BU centers in Bénin between January 2008 and December 2010 was collected using the WHO/BU01 forms. Information used from these forms included general characteristics of the patient, the results of diagnostic tests, the presence of functional limitations at start of treatment, lesion size, patient delay and the referral system. The role of the different referral systems on the stage of disease at presentation in the hospital was analyzed by a logistic regression analysis. About a quarter of the patients (26.5%) were referred to the hospital by the community health volunteers. In our data set, patients referred to the hospital by community health volunteers appeared to be in an earlier stage of disease than patients referred by other methods, but after adjustment by the regression analysis for the health center, this effect could no longer be seen. The Polymerase Chain Reaction (PCR) for IS2404 positivity rate among patients referred by the community health volunteers was not systematically lower than in patients referred by other systems. Conclusions/Significance This study clarifies the role played by community health volunteers in Bénin, and shows that they play an important role in the control of BU.
