Techniques for estimating densities of Bulinus truncatus rohlfsi and its horizontal distribution in Volta Lake, Ghana. (1/36)

Bulinus truncatus rohlfsi is the intermediate host of urinary schistosomiasis, which is highly endemic in the man-made Volta Lake. In 1971, a WHO/UNDP schistosomiasis project was established in the Pawmpawm branch and part of the Afram branch of Volta Lake. Malacological findings of the preliminary phase indicated that the snails were distributed in the littoral zone of the lake, and that this distribution was correlated with the presence of vegetation, especially Ceratophyllum. Transmission nearly always occurred in "water contact sites", i.e., places where people come into contact with water.A snail-sampling technique with palm-leaf mats was developed and standardized after it had been shown in sensitivity trials to compare favourably with a modified version of the "man-time" sampling method, in which the number of snails collected per man-hour is recorded. It is recommended that both these methods should be used to conduct ecological studies of B. rohlfsi in water contact sites.  (+info)

A large-scale snail control trial with trifenmorph in the Gezira irrigation scheme, Sudan. (2/36)

A large-scale field trial was carried out during December 1973 to assess the effect of trifenmorph on Bulinus truncatus and Biomphalaria pfeifferi in 379 000 feddans ( approximately 159 000 ha) of the Gezira irrigation system in the Sudan. The commercial formulation used (Frescon) is an emulsifiable concentrate containing 16.5% trifenmorph. Five dispensers were used to add the commercial product to the water continuously for 7.5 days; 18 121 litres were used to treat 28.4 million m(3) of water. In addition, each minor canal was hand-sprayed from the tail to 300 m upstream of the last open field outlet pipe; 360 litres of the commercial formulation were used for this operation.A minimum concentration of 0.035 mg trifenmorph per litre of water was produced at the head of each minor canal. The use of caged snails showed that a concentration as low as 0.015 mg/litre was sufficient to produce 100% mortality in B. truncatus in 7.5 days; this is equivalent to a concentration x time product of 0.12 mg/litre days.  (+info)

Toxic activities of the plant Jatropha curcas against intermediate snail hosts and larvae of schistosomes. (3/36)

The aim of studies on plant molluscicides is to complement methods for controlling snails acting as intermediate hosts of schistosomes. We report on the toxic activity of extracts from Jatropha curcas L. (Euphorbiaceae) against snails transmitting Schistosoma mansoni and S. haematobium. We studied different extracts' effects on infectious larvae, cercariae and miracidia of S. mansoni. Compared to aqueous extract, methanol extract showed the highest toxicity against all tested organisms with LC100-values of 25 p.p.m. for cercariae and the snail Biomphalaria glabrata and 1 p.p.m. for the snails Bulinus truncatus and B. natalensis. Attenuation of cercariae leading to reduced infectivity in mice could be achieved in concentrations below those exerting acute toxicity. In view of our results and the ongoing exploitation of J. curcas for other purposes, this plant could become an affordable and effective component of an integrated approach to schistosomiasis control.  (+info)

Evaluation of environmental methods to control snails in an irrigation system in Central Morocco. (4/36)

The Moroccan Ministry of Public Health has launched a programme to eliminate schistosomiasis. One of the components in this process is the control of Bulinus truncatus, the intermediate host snail of Schistosoma haematobium. We evaluated three environmentally safe measures to control B. truncatus in siphon boxes, the main breeding sites for these snails in the Tessaout Amont irrigation system. The first method involved covering the siphon boxes to exclude light and reduce algal growth, the second consisted of increasing the frequency of emptying and cleaning the siphon boxes, and the third method increased water velocity to hinder the establishment of the intermediate hosts. The results showed that covering had a pronounced effect on snail and egg mass density, was accepted by the local community and prevented water contact. Cleaning the siphons three times during the irrigation season led to a reduction in snail density although it was not statistically significant and recolonization was rapid. Increasing water velocity by reducing the dimensions of siphon boxes delayed recolonization, but such a control measure can be applied only in specific situations where it does not pose hydraulic problems. The three interventions were selectively effective against B. truncatus, whereas other snails such as Physa acuta and Lymnaea peregra were hardly affected. Covering, the most promising control measure, could be useful in the Moroccan schistosomiasis eradication programme. However, further investigations are needed to assess its impact on water quality.  (+info)

PCR-RFLP analysis of the ITS2 region to identify Schistosoma haematobium and S. bovis from Kenya. (5/36)

Schistosoma haematobium, primarily a human parasite, and the closely related Schistosoma bovis from ruminants, are sympatric in many African countries such as Kenya. Because these two species 1) can inhabit the same Bulinus snails, 2) may be found in the same freshwater habitat, and 3) have morphologically similar cercariae, better means are needed to tell them apart. The second internal transcribed spacer (ITS2) region of the ribosomal gene complex (rDNA) of recent Kenyan isolates of both species was sequenced and found to be a 98% match. The S. bovis sequences were nearly identical (99%) to conspecific sequences from Niger; the S. haematobium sequences were nearly identical (99%) to conspecific sequences from Egypt, Mali, and Niger. Restriction fragment length polymorphism (RFLP) analysis of a 480 base pair (bp) PCR product containing the ITS2 region using two restriction enzymes, Taq1 and Sau3A1, yielded species-specific fragment patterns that allowed successful identification of a single S. haematobium cercaria. The protocol outlined here is useful in providing a rapid, one-day identification of S. haematobium (and likely S. bovis) cercariae (the infective larval stage) and/or other life cycle stages in a basic molecular biology laboratory. By helping to determine whether schistosome-infected bulinid snails in a particular body of water are transmitting a human or an animal schistosome, or both, this analysis will aid in disease control and in ongoing epidemiological studies.  (+info)

Studies on the biology of schistosomiasis with emphasis on the Senegal river basin. (6/36)

The construction of the Diama dam on the Senegal river, the Manantali dam on the Bafing river, Mali and the ensuing ecological changes have led to a massive outbreak of Schistosoma mansoni in Northern Senegal, associated with high intensity of infections, due to intense transmission, and the creation of new foci of S. haematobium. Data on the vectorial capacity of Biomphalaria pfeifferi from Ndombo, near Richard Toll, Senegal are presented with sympatric and allopatric (Cameroon) S. mansoni. Comparisons are made on infectivity, cercarial production, chronobiology of cercarial emergence and longevity of infected snails. Recent data on the intermediate host specificity of different isolates of S. haematobium from the Lower and Middle Valley of the Senegal river basin (SRB) demonstrate the existence of at least two strains of S. haematobium. The role of Bulinus truncatus in the transmission of S. haematobium in the Lower and Middle Valleys of the SRB is reviewed. Both S. haematobium and S. mansoni are transmitted in the same foci in some areas of the SRB.  (+info)

Ontogenetic reaction norm for binary traits: the timing of phallus development in the snail Bulinus truncatus. (7/36)

The ontogenetic trajectory of plastic binary traits may provide valuable insights into their evolutionary rate of change. In this paper, the timing of the plastic response of a temperature-dependent sexual polymorphism, aphally, is investigated in the freshwater snail Bulinus truncatus. Aphally is defined as the loss of the male copulatory organ in otherwise hermaphroditic animals. Individuals from two inbred lines were switched at various times during their early development between 25 and 30 degrees C, and their phally status ascertained, in order to evaluate the parameters characterising the ontogenetic reaction norm of aphally to temperature. A series of nested models including parameters for the onset, offset, and the intensity of the response to temperature were fitted to the data, allowing for a wide range of reaction norms. One genotype did not show any variation in aphally ratio with switching temperature, while a switch-point model (onset and offset corresponding to the same developmental point in time) best fitted the second genotype. The results suggest that the plasticity of aphally is expressed before eggs hatch. Their consequences on the evolution of aphally are discussed. More generally, the methodology proposed here can be used to analyse variation in ontogenetic parameters of discrete traits.  (+info)

Identification of snails within the Bulinus africanus group from East Africa by multiplex SNaPshot trade mark analysis of single nucleotide polymorphisms within the cytochrome oxidase subunit I. (8/36)

Identification of populations of Bulinus nasutus and B. globosus from East Africa is unreliable using characters of the shell. In this paper, a molecular method of identification is presented for each species based on DNA sequence variation within the mitochondrial cytochrome oxidase subunit I (COI) as detected by a novel multiplexed SNaPshotTM assay. In total, snails from 7 localities from coastal Kenya were typed using this assay and variation within shell morphology was compared to reference material from Zanzibar. Four locations were found to contain B. nasutus and 2 locations were found to contain B. globosus. A mixed population containing both B. nasutus and B. globosus was found at Kinango. Morphometric variation between samples was considerable and UPGMA cluster analysis failed to differentiate species. The multiplex SNaPshotTM assay is an important development for more precise methods of identification of B. africanus group snails. The assay could be further broadened for identification of other snail intermediate host species.  (+info)

'Bulinus' is a genus of freshwater snails that have a spiral, coiled shell. These snails are aquatic pulmonate gastropod mollusks, which means they breathe air but live in water. They are often found in tropical and subtropical regions of Africa and the Middle East.

Bulinus snails are known to be intermediate hosts for several species of parasitic flatworms that cause schistosomiasis (also known as bilharzia), a chronic and debilitating disease that affects millions of people worldwide, particularly in developing countries with poor sanitation and access to safe water.

The most common species of Bulinus snails involved in the transmission of schistosomiasis are Bulinus truncatus and Bulinus globosus. These snails ingest the larval stage of the parasitic flatworms, which then develop into a different larval stage inside the snail's tissues. When an infected snail releases its faeces into the water, the larval flatworms are released and can infect humans who come into contact with the contaminated water.

Therefore, Bulinus snails play a crucial role in the life cycle of these parasites and are an important public health concern in areas where schistosomiasis is endemic.

I'm sorry for any confusion, but the term "snails" is not a medical term. It is a common name used to refer to a large group of land and sea-dwelling mollusks that have coiled shells and move slowly by means of a muscular foot. If you have any questions about medical terminology or health-related topics, I'd be happy to help! Just let me know what you're looking for.

Schistosoma is a genus of flatworms that cause the disease schistosomiasis, also known as snail fever. These parasitic worms infect freshwater snails and then release a form of the parasite that can penetrate the skin of humans when they come into contact with contaminated water. The larvae mature into adult worms in the human body, living in the blood vessels of the bladder, intestines or other organs, where they lay eggs. These eggs can cause serious damage to internal organs and lead to a range of symptoms including fever, chills, diarrhea, and anemia. Schistosomiasis is a significant public health problem in many tropical and subtropical regions around the world.

Schistosomiasis, also known as bilharzia or snail fever, is a parasitic infection caused by several species of the trematode flatworm Schistosoma. The infection occurs when people come into contact with freshwater contaminated with the parasite's larvae, which are released by infected freshwater snails.

The larvae penetrate the skin, enter the bloodstream, and mature into adult worms in the blood vessels of the urinary tract or intestines. The female worms lay eggs, which can cause inflammation and scarring in various organs, including the liver, lungs, and brain.

Symptoms of schistosomiasis may include fever, chills, cough, muscle aches, and diarrhea. In chronic cases, the infection can lead to serious complications such as kidney damage, bladder cancer, and seizures. Schistosomiasis is prevalent in tropical and subtropical regions with poor sanitation and lack of access to safe drinking water. It is preventable through improved water supply, sanitation, and snail control measures. Treatment typically involves the use of a medication called praziquantel, which kills the adult worms.

"Schistosoma haematobium" is a species of parasitic flatworm, also known as a blood fluke, that causes the disease schistosomiasis (also known as bilharzia). This specific species is the most common cause of urogenital schistosomiasis.

The life cycle of Schistosoma haematobium involves freshwater snails as intermediate hosts. The parasite's eggs are released in the urine of an infected person and hatch in fresh water, releasing miracidia that infect the snail. After several developmental stages, the parasites emerge from the snail as free-swimming cercariae, which then infect the human host by penetrating the skin during contact with infested water.

Once inside the human body, the cercariae transform into schistosomula and migrate to the venous plexus around the bladder, where they mature into adult worms. The female worms lay eggs that can cause inflammation and damage to the urinary tract and, in some cases, other organs. Symptoms of infection can include blood in the urine, frequent urination, and pain during urination. Chronic infection can lead to more serious complications, such as bladder cancer and kidney damage.

Molluscicides are a type of pesticide specifically designed to kill mollusks, which include snails and slugs. These substances work by interfering with the mollusk's nervous system, leading to paralysis and death. Molluscicides are often used in agricultural settings to protect crops from damage caused by these pests, but they can also be found in residential products designed to control nuisance snails and slugs in gardens or landscaping.

It is important to note that molluscicides can be harmful to other organisms as well, including pets and wildlife, so they should be used with caution and according to the manufacturer's instructions. Additionally, some molluscicides may pose risks to human health if not handled properly, so it is essential to follow safety guidelines when using these products.

I'm sorry for any confusion, but "Schistosomiasis haematobia" is not a recognized medical term. Schistosomiasis is a parasitic disease caused by several species of blood flukes (schistosomes). The two main forms that affect humans are Schistosoma mansoni and Schistosoma haematobium, but the term "haematobia" itself refers to the presence of blood in urine.

So, when we talk about Schistosoma haematobium, it's a specific species of schistosome that causes an infection known as urogenital schistosomiasis, which is characterized by the presence of blood in the urine (haematuria) and other symptoms.

If you have any questions about tropical diseases or parasitic infections, feel free to ask!

A disease vector is a living organism that transmits infectious pathogens from one host to another. These vectors can include mosquitoes, ticks, fleas, and other arthropods that carry viruses, bacteria, parasites, or other disease-causing agents. The vector becomes infected with the pathogen after biting an infected host, and then transmits the infection to another host through its saliva or feces during a subsequent blood meal.

Disease vectors are of particular concern in public health because they can spread diseases rapidly and efficiently, often over large geographic areas. Controlling vector-borne diseases requires a multifaceted approach that includes reducing vector populations, preventing bites, and developing vaccines or treatments for the associated diseases.

'Biomphalaria' is a genus of freshwater snails that are intermediate hosts for the parasitic flatworms that cause schistosomiasis, also known as snail fever. This is a type of trematode infection that affects humans and other animals. The snails of the 'Biomphalaria' genus are native to Africa and parts of South America and play an essential role in the life cycle of the parasitic worms that cause this disease.

Schistosomiasis is a significant public health issue, particularly in developing countries with poor sanitation and hygiene. The World Health Organization (WHO) estimates that more than 200 million people worldwide are infected with schistosomes, resulting in tens of thousands of deaths each year. Effective control of the disease requires a multi-faceted approach, including the prevention of transmission through snail control and the treatment of infected individuals with praziquantel, the drug of choice for schistosomiasis.
