Aklilu Lemma
Aklilu Lemma (; 18 September 1935 – 5 April 1997) was an Ethiopian pathobiologist. In 1989, he was awarded the Right Livelihood Award "for discovering and campaigning relentlessly for an affordable preventative against bilharzia." Education Lemma was educated at Addis Ababa University College and at Johns Hopkins University in the U.S. where he obtained his D.Sc. in 1964. His dissertation was on sandfly-borne leishmaniasis. Career Following his doctorate, Lemma returned to his home country, Ethiopia, where he obtained a position at the then Haile Selassie I University. He founded the Institute of Pathobiology, now known as the Aklilu Lemma Institute of Pathobiology, and taught there until 1976, when he left it for a job in the United Nations. He served the UN in many capacities as a scientist, became the Deputy Director of UNICEF's International Child Development Centre, now known as UNICEF's Innocenti Research Centre and finally obtained a position in his alma mater, Jo ...

Jijiga
Jijiga (, am, ጅጅጋ, ''Jijiga'') is the capital city of Somali Region, Ethiopia. It became the capital of the Somali Region in 1995 after it was moved from Gode. Located in the Fafan Zone with 70 km (37 mi) west of the border with Somalia, the city has an elevation of 1,634 metres above sea level. Jigjiga is traditionally the seat of the Bartire Garad Wiil-Waal of the Jidwaaq Absame. The International airport is named after him. History The region around Jijiga is believed to be associated with the ancient Gidaya state which existed as early as thirteenth century. Jijiga was mentioned by W.C. Barker in 1842 as one of the ''mahalla'' or halting-places of the caravan route between Zeila and Harar. One of the earliest detailed references to Jijiga comes from British hunter Colonel Swayne, who passed through Jijiga in February 1893, which he described as a stockaded fort with a garrison of 25 men next to a group of wells. According to I. M. Lewis, the Dervish ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Schistosomiasis
Schistosomiasis, also known as snail fever, bilharzia, and Katayama fever, is a disease caused by parasitic flatworms called schistosomes. The urinary tract or the intestines may be infected. Symptoms include abdominal pain, diarrhea, bloody stool, or blood in the urine. Those who have been infected for a long time may experience liver damage, kidney failure, infertility, or bladder cancer. In children, it may cause poor growth and learning difficulty. The disease is spread by contact with fresh water contaminated with the parasites. These parasites are released from infected freshwater snails. The disease is especially common among children in developing countries, as they are more likely to play in contaminated water. Other high-risk groups include farmers, fishermen, and people using unclean water during daily living. It belongs to the group of helminth infections. Diagnosis is by finding eggs of the parasite in a person's urine or stool. It can also be confirmed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ethiopian Biologists
Ethiopians are the native inhabitants of Ethiopia, as well as the global diaspora of Ethiopia. Ethiopians constitute several component ethnic groups, many of which are closely related to ethnic groups in neighboring Eritrea and other parts of the Horn of Africa. The first documented use of the name "Ethiopia" from Greek name "Αἰθίοψ" (Ethiopian) was in the 4th century during the reign of Aksumite king Ezana. There were three ethnolinguistic groups in the Kingdom of Aksum; Semitic, Cushitic, and Nilo-Saharan (ancestors of the modern-day Kunama and Nara). The Kingdom of Aksum remained a geopolitically influential entity until the pillage of its capital — also named Axum — in the 10th century by Queen Gudit. Nevertheless, the core Aksumite civilization was preserved and continued into the successive Zagwe dynasty. By this time, new ethnic groups emerged – the Tigrayans and Amharas. During the Solomonic period, the latter established major political and cult ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Molluscicide
Molluscicides () – also known as snail baits, snail pellets, or slug pellets – are pesticides against molluscs, which are usually used in agriculture or gardening, in order to control gastropod pests specifically slugs and snails which damage crops or other valued plants by feeding on them. A number of chemicals can be employed as a molluscicide: * Metal salts such as iron(III) phosphate, aluminium sulfate, and ferric sodium EDTA, relatively non-toxic, also used in organic gardening * Metaldehyde * Niclosamide * Acetylcholinesterase inhibitors (e.g. methiocarb), highly toxic to other animals and humans, acts also as a contact poison Accidental poisonings Metal salt-based molluscicides are not toxic to higher animals. However, metaldehyde-based and especially acetylcholinesterase inhibitor-based products are highly toxic, and have resulted in many deaths of pets and humans. Some products contain a bittering agent that reduces but does not eliminate the risk of accid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phytolacca Dodecandra
''Phytolacca dodecandra'', commonly known as endod, gopo berry, or African soapberry, is a trailing shrub or climber native to Tropical Africa, Southern Africa, and Madagascar. It is dioecious, with male and female flowers on separate plants. Morphologically, it is highly variable. ''Endod'' (as it is known in Amharic or ''shibti'' in Tigrigna ) has been selected and cultivated by Africans for centuries, particularly in Ethiopia and Eritrea. It is used as a soap and shampoo as well as a poison to stun fish. ''Endod'' is lethal to snails - a fact discovered by Ethiopian scientists - and may be effective controlling schistosomiasis. After Aklilu Lemma, an Ethiopian scientist, demonstrated endod's potency to American scientists, they took out a patent, hoping to sell endod as a biological control for the Zebra mussel, a pest in the Great Lakes of the US and Canada. In Ethiopia, two types of "endod" (''Phytolacca dodecandra'') are known to grow and, while the tree's bark are root ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Freshwater Snail
Freshwater snails are gastropod mollusks which live in fresh water. There are many different families. They are found throughout the world in various habitats, ranging from ephemeral pools to the largest lakes, and from small seeps and springs to major rivers. The great majority of freshwater gastropods have a shell, with very few exceptions. Some groups of snails that live in freshwater respire using gills, whereas other groups need to reach the surface to breathe air. In addition, some are amphibious and have both gills and a lung (e.g. '' Ampullariidae''). Most feed on algae, but many are detritivores and some are filter feeders. According to a 2008 review of the taxonomy, there are about 4,000 species of freshwater gastropods (3,795–3,972). At least 33–38 independent lineages of gastropods have successfully colonized freshwater environments. It is not possible to quantify the exact number of these lineages yet, because they have yet to be clarified within the Cerit ...

Schistosoma
''Schistosoma'' is a genus of trematodes, commonly known as blood flukes. They are parasitic flatworms responsible for a highly significant group of infections in humans termed '' schistosomiasis'', which is considered by the World Health Organization as the second-most socioeconomically devastating parasitic disease (after malaria), with hundreds of millions infected worldwide. Adult flatworms parasitize blood capillaries of either the mesenteries or plexus of the bladder, depending on the infecting species. They are unique among trematodes and any other flatworms in that they are dioecious with distinct sexual dimorphism between male and female. Thousands of eggs are released and reach either the bladder or the intestine (according to the infecting species), and these are then excreted in urine or feces to fresh water. Larvae must then pass through an intermediate snail host, before the next larval stage of the parasite emerges that can infect a new mammalian host by dir ...
