Abstract: This study evaluated the antimicrobial activities of crude ethanolic and aqueous extracts of Aloe vera using standard techniques. Results obtained revealed reasonable antimicrobial activities on the tested organisms to varying zone of inhibitions. The activities however were found to be concentration dependent while no apparent statistical disparity was observed with the different extracting solvents (tvalue = 0.88, p>0.05). The minimum inhibitory dilution of both extracts range from 25-100mg/ml. It can thus be inferred that the tested Aloe vera has good antimicrobial properties.

Abstract: The study of ecological factors determining the distribution and species abundance of vectors of human mosquito borne-infections was undertaken in four selected communities in some parts of Gwagwalada, an Area Council in Abuja, Nigeria. These sites are Tunganmaje, Paiko Kore, Kutunku and Dobi. Approximately sixty three percent (63%) of the mosquitoes bred in clear water while 18.50% mostly Culex was found to breed in water containing turbid matter. All mosquito genera encountered were collected from shallow water and none were found in deep water habitats. All genera of mosquito breed in shaded and sun-lit habitats. Culex mosquitoes breed in all types of habitat both with and without vegetation cover, while none were found in floating plants. Culex was only collected in habitats with vegetative cover except the presence of algae while Anopheles preferred both habitats with or without vegetation cover except those with floating plants. The Simpson’s indices of diversity for the types of breeding sites, species of mosquito and their seasonal distribution varied significantly (P<0.01) in this study. Most identified habitats were largely associated with human activities. When seeking novel avenues for ecological control of mosquitoes and mosquito borne diseases, mosquito breeding behavior should receive more attention.

Abstract: A study was conducted to investigate the water quality of five important lakes - Osman Sagar, Himayat Sagar, Langer House Lake, Jeedimetla Lake, Patan Cheruvu Lake which are located in and around Hyderabad. The sampling points were selected on the basis of their importance. The surface water samples were taken from the above said lakes during the period of winter in the month of October and November 2011. Water samples were analyzed for various physico-chemical parameters like pH, conductivity, turbidity, chlorides, hardness, alkalinity, total dissolved solids (TDS), dissolved oxygen (DO), phosphate, sulphate, biological oxygen demand (BOD) and chemical oxygen demand (COD). The present study showed detailed physico-chemical characteristics and quality of water of five studied important lakes. From the present investigation, it indicated that Langer House Lake, Jeedimetla Lake and Patancheru Lake are polluted, hence making it unsuitable for human consumption. The Lakes Osman Sagar and Hiamayat Sagar shows concentrations of all the physicochemical parameters well below the desirable limit recommended by BIS, thus the water of Osman Sagar and Himayat Sagar most suitable for survival of the fishes and for supply of drinking water to the Hyderabad city. A direct effect of human activities on the pollution status was observed in all the lakes. The overall objective of this work was to investigate the lake water quality and suggests the means to improve the lake water quality.

Abstract: The aim of this paper is to describe the epidemiology, clinical sign, diagnosis, economic significance, control and prevention of lumpy skin disease. Lumpy skin disease is an acute infectious disease of cattle endemic in most Sub-Saharan African countries. It is caused by lumpy skin disease virus in the genus Capripoxvirus. It is a disease with a high morbidity and low mortality rate that affects cattle of all ages and breeds. However, Bostaurus cattle breeds are more susceptible than Bosindicus breeds, and young animals often experience more severe disease than adults. The most important method of transmission is mechanically through biting flies. The incidence of lumpy skin disease is high during wet seasons when biting-fly populations are abundant. The disease is characterized by fever, development of firm, well demarked nodules on the skin, mucous membranes and internal aspects of the body and enlargement of the local drainage lymph nodes. The diagnosis of lumpy skin disease is based on history, clinical signs and laboratory confirmation. There is no specific treatment for lumpy skin disease, but animals can be treated with antibiotics to prevent secondary infections. Vaccinations, animal movement restriction, quarantine, insect control, slaughter and proper disposal of animals and contaminated material are the basic methods to control lumpy skin disease. The disease has a significant economic importance to cattle industry due to reduction in production, damaged hides and deaths. Therefore, appropriate control and prevention methods should be carried out to overcome the economic loss associated with the disease.

Abstract: In past years, Water resource limitation is one of most important challenges of human life. Poor management of this resource, growing competition in fresh water consumption and quality degradation; only exacerbate the problem of water scarcity (dairy et al). Increasing concentration of population is the one of important factors that affect quality of water resources. This is common factor of excessive stress on arid regions water resources.

Abstract: The present study was aimed at assessing the ground water quality characteristics of Gwalior City. A comprehensive physico-chemical and microbiological analysis was conducted after the ground water samples were collected from different sampling locations. The study was carried out by collecting four ground water samples (two bore wells and two municipal supply water) during January-March 2012. The results were compared with Standards prescribed by WHO and ISI-10500-91. The parameters include temperature, total dissolved solids (TDS), pH, Electrical conductivity (EC), Total alkalinity (TA), Chlorides (Cl-), Total hardness (TH), Dissolved oxygen (DO), Total aerobic microbial count (TAMC) and Bacterial count (MPN/100 mg/l coliforms). The observation of the study strongly suggests that water of Gwalior region is of very high TDS and needs to be lowered down within prescribed limits before using it for drinking purposes. The present work is primary attempt to examine the water quality of various potable water resources in and around Gwalior City of M.P., India.

Abstract: A survey of the prevalence of malariaamong subjects presented with fibril illness in Yangoji and Gwagwalada areas of the Federal Capital Territory, was conducted from June 2015 to January 2016 at the University of Abuja Teaching Hospital in Gwagwalada and the Primary Health Care Centre in Yangoji, Kwali Area Council. A total of 500 individuals resident in Gwagwalada and Yangoji were examined for the presence of malaria parasiteamia microscopically. In Yangoji a rural community, of the 250 individuals sampled, the result showed a prevalence rate of 54.40% while the 250 number of individuals examined in Gwagwalada an urban settlement a prevalence rate of 47.20% was established. There was no significant difference in the prevalence of malaria between Yangoji and Gwagwalada (P-value > 0.05). There tends to be higher prevalence of malaria parasiteamia among males in both rural and urban areas 61.90% and 52.21% than females 48.96% and 43.07% respectively. Parasite intensity ranges from 102.00l to 1590.90l. Plasmodium falciparum was found to be the most prevalent species 87.78% and 89.87%, followed by P. vivax 6.49% and 5.26, while mixed infection was 5.73% and 4.86% respectively in the urban and rural areas. No observation of P.malariea and p. ovale. was encountered.

Abstract: Rural women constitute about half of the world’s population and in the world production supply they have energetic communion and constitute a great part of agriculture workforce. They constitute 50% of the workforce and they participate in the production of half of the foods in the agriculture section. As an example the rural women constitute about 70 to 80% of agriculture workforce in sub-Saharan Africa, 65% in Asia, 45% in Latin American & Caribbean, 80% in Nigeria & Tunisia and 80% in India, but their role in production system is the men’s supplements roles and this causes a big responsibility inside their mother & wife duties and it takes a great time and energy of them. Studies in this field show that women spend about two thirds of their time for production, management & organize of their house as the men spend only one third of their time for such things. rural woman helps to prepare farm, then she plows, harvests, does weeding and transplants, does milking and also acts as shepherd, weaves carpet, tries to make tools and handicrafts, bakes bread, cooks, does housekeeping duties, fetches water from water sources and from distances, fetches firewood, cares children, spins wool and makes curd, buttermilk, yogurt, butter and oil. In addition to all these, she is mother and family supervisor too. In spite of that rural women in developing countries are producer of about 80% of foods and responsible of supervising of about 30% of rural families, but their activities wasn’t considered as economic activity and simply are removed from agriculture and rural development programs.
