Box , Mekelle, Ethiopia. Leishmaniasis is a parasitic disease caused by obligate intracellular protozoans of the genus Leishmania. To assess the distribution of human leishmaniasis and assess community knowledge, attitude, and practice with regard to assumed risk factors and control options used by the society.

Distribution of Human Leishmaniasis (VL) and Its Associated Risk Factors, in Metemma, Ethiopia

Metrics details. Ethiopia is affected by human leishmaniasis caused by several Leishmania species and transmitted by a variety of sand fly vectors of the genus Phlebotomus. The sand fly fauna in Ethiopia is highly diverse and some species are closely related and similar in morphology, resulting in difficulties with species identification that requires deployment of molecular techniques. DNA barcoding entails high costs, requires time and lacks reference sequences for many Ethiopian species. Yet, proper species identification is pivotal for epidemiological surveillance as species differ in their actual involvement in transmission cycles. In our study, we used an integrative taxonomic approach to identify most of the important sand fly vectors of leishmaniasis in Ethiopia, applying three complementary methods: morphological assessment, sequencing analysis of two genetic markers, and MALDI-TOF MS protein profiling.

Epidemiology of visceral leishmaniasis

Visceral leishmaniasis VL is a neglected tropical disease, which is strongly associated with poverty. VL caused by Leishmania donovani and transmitted by Phlebotomus orientalis is endemic in various remote areas of north and north-west Ethiopia. The present study was designed to determine the sand fly fauna and bionomics of P. All sand fly specimens collected were identified to species level and counted. In total, , sand fly specimens, belonging to 25 sand fly species nine Phlebotomus and sixteen Sergentomyia were collected and identified. As it could be determined from the proportion of collections from outdoor peri-domestic and agricultural fields and indoor locations, P.

Ochollo is a village in southern Ethiopia burdened with cutaneous leishmaniasis CL , where Phlebotomus pedif er is the only vector for Leishmania aethiopica and hyraxes are confirmed reservoir hosts. A detailed description of the different players of transmission, and the ecology and seasonality of the vector needs to be established in order to accomplish efficient control programs. Between March and February , a monthly sandfly collection was carried out in different habitats and records of temperature and humidity were taken. Rodents and hyraxes were trapped in the dry and wet season. Additionally, the species of sandfly specimens from different habitats and seasons was identified. The overall sandfly and P.

Visceral leishmaniasis and cutaneous leishmaniasis are important public health problems in Ethiopian lowland and highland areas respectively. Control of leishmaniasis requires proper understanding of human parasites transmissions anthroponotic or zoonotic or both. The aim of this review was to elaborate different ecologies of leishmaniasis based on evidences from previous researches and information from literatures obtained from different sources including PubMed to describe zoonotic leishmaniasis in Ethiopia with possible control methods.

Visceral leishmaniasis VL has been known to occur since the s on the western bank of the White Nile River Central Sudan , km south of Khartoum, and has resulted in high mortality. The most recent outbreak of the disease in this area began in Sandflies were collected using Centers for Disease Control light traps and sticky oil traps in the village of Kadaba and the nearby woodland. Phlebotomus females were dissected for the presence of Leishmania promastigotes.

Background

Вы только посмотрите на эту палату. Мою колонку перепечатывают издания по всему миру. - Сэр! - Беккер поднял обе руки, точно признавая свое поражение.  - Меня не интересует ваша колонка. Я из канадского консульства. Я пришел, чтобы убедиться, что с вами все в порядке. Внезапно в гимнастическом зале, превращенном в больничную палату, повисла тишина.

 Набросок или отшлифованный до блеска экземпляр, - проворчал Джабба, - но он дал нам под зад коленом. - Не верю, - возразила Сьюзан.  - Танкадо был известен стремлением к совершенству. Вы сами это знаете. Он никогда не оставил бы жучков в своей программе. - Их слишком много! - воскликнула Соши, выхватив распечатку из рук Джаббы и сунув ее под нос Сьюзан.

Его густые волосы имели натуральный песочный оттенок, а глаза отливали яркой голубизной, которая только усиливалась слегка тонированными контактными линзами. Оглядывая свой роскошно меблированный кабинет, он думал о том, что достиг потолка в структуре АНБ. Его кабинет находился на девятом этаже - в так называемом Коридоре красного дерева. Кабинет номер 9А197. Директорские апартаменты.

Сьюзан не оставляло подозрение, что в компьютере шефа кроется нечто, чему в один прекрасный день суждено изменить весь мир. Да, я была с ним слишком сурова, - подумала Сьюзан.

 Чтобы вы меня убили. - Я не собираюсь тебя убивать. Мне нужен только ключ. - Какой ключ. Стратмор снова вздохнул.

Вначале он хотел снять его, но белая оксфордская рубашка была бы ничуть ни лучше, поэтому он лишь пригнулся еще ниже.
