Free Living Amoeba

Studies on waterborne parasites from natural environment and domestic water sources in Uganda are very scarce and unpublished. Water dwelling free-living amoebae (FLA) of the genus Acanthamoeba, Hartmannella, and Naegleria are often responsible for causing morbidities and mortalities in individuals with recent contact with contaminated water, but their presence in Uganda’s public water supply sources is not known. We cultivated and genotyped FLA from natural and domestic water from Queen Elizabeth Protected Area (QEPA) and Kampala (KLA). The cultivated parasites were observed microscopically and recorded. The overall prevalence of FLA in QEPA (Acanthamoeba spp., 35%; Hartmannella spp., 18.9%; Naegleria spp., 13.5%) and KLA (Acanthamoeba spp., 28.3%; Naegleria spp., 16.6%; Hartmannella spp., 23.1%) were not significantly different. The highest prevalence across water sources in QEPA and KLA was observed for Acanthamoeba spp., followed by Hartmannella spp., and Naegleria spp. Overall FLA mean (±SE) and mean (±SE) across water sources were highest for Acanthamoeba spp. compared to other FLA but were not statistically significant (p > 0.05). Analysis of the FLA sequences produced 1 Cercomonas, 1 Nuclearia, 1 Bodomorpha, 2 Hartmannella, 5 Echinamoeba, and 7 Acanthamoeba partial sequences, indicating a muliplicity of water contaminants that need to be controlled by proper water treatment.

Sterile Processing

AbstractExcessive rainfall and dam failures resulted in floodwater contaminating our public water supply. The endotoxin risk in the contaminated water created challenges in recovery of sterile processing for our surgical equipment. Recovery plans should include a potable water source and a method to connect it to the required location. We share our solution of plumbing our sterile processing equipment to tanker-transported potable water sources. (Disaster Med Public Health Preparedness. 2018; 12: 415–418)

Проведенный анализ современных нормативноправовых документов и практики оценки физического износа структурно сложных объектов водопроводноканализационного хозяйства показал, что современные методы оценки не учитывают особенности этих объектов. Выявлены факторы, влияющие на структуру показателей оценки физического износа по основным группам и элементам объектов водопроводноканализационного хозяйства. На их основе разработан алгоритм оценки физического износа объектов с применением рискориентированного подхода для трех уровней: объект, технологические элементы объекта (сооружения), функциональные элементы в составе сооружений (здания, оборудование). Использование алгоритма позволяет разработать рекомендации по корректировке периодичности и частоте проведения мониторинга показателей уровня физического износа объектов централизованных систем водоснабжения и водоотведения и их элементов. Практическое применение разработанного алгоритма будет способствовать внедрению современных подходов по управлению рисками, связанными с уровнем физического износа и оценкой вероятности потенциальных негативных последствий природного, антропогенного и другого характера. Внедрение алгоритма позволит также устанавливать уязвимые области и проводить предупредительные мероприятия в отношении возникновения угрозы нарушения обязательных требований, в том числе меры по снижению рисков (техникотехнологическое обновление зданий, сооружений, оборудования). Это необходимо для объективного и обоснованного планирования капитального ремонта, восстановления и развития объектов водопроводноканализационного хозяйства и их элементов.The paper analyzes current regulatory documents and experience in the field of assessing the deterioration of structurally complex water supply and sanitation facilities. The paper shows that modern assessment procedures do not take into account any features of such objects. The paper identifies factors that affect the indicator framework for assessing the physical deterioration of the main groups and components of water supply and sanitation facilities. Based on these factors, the paper proposes an algorithm for assessing the physical deterioration of facilities using a riskoriented approach for three levels: an object itself, its engineering components (facilities), and their functional elements (buildings, equipment). The paper indicates that the use of the algorithm would provide for developing recommendations for adjusting the frequency of monitoring indicators of the physical deterioration level of facilities of public water supply and sanitation systems and their elements. The implementation of the developed algorithm would contribute to the successful introduction of advanced approaches to managing risks associated with the level of physical deterioration and assessing the probability of potential negative consequences of natural, anthropogenic, and other origins. The introduction of the algorithm would also allow identifying vulnerable areas and taking preventive measures against the threat of violation of mandatory requirements including measures for reducing risks (technical and engineering renovation of buildings, facilities, equipment). This is required for objective and substantiated planning of overhaul, restoration, and development of water supply and sanitation facilities and their components.

Goat Farming

The present study was conducted Bathinda, Fazilka, and Muktsar of Punjab to examine the socio-economic and general profile of goat farmers, studying a total sample of 88 goat farmers. Both types of goat farming systems, organized goat farms, and traditional goat farms, were studied with more emphasis on organized goat farms. The sample farmers consisted of 56 organized and 32 traditional goat farmers in the state. It was observed in the study that the education level of organized goat farmers was better compared to traditional goat farmers. A majority of the sample goat farmers had nuclear families. A majority of the farmers (53.57 percent) had goat farms located in the village. Organized goat farms had tube-well as the main source of water supply, whereas traditional goat farms were mainly dependent upon public water supply. Organized goat farmers had relatively higher exposure to training. A vast majority of the goat farmers had their breeding buck.
