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)

d).. This alternation suggests that a uniform conformation of Leu32 is impossible. In the interface between M3 and M4 of YIIIM5AII, where we observe the largest distance between Trp33 Cα atoms, Leu158 CD1 (Leu32 in M3) and Thr202 OG1 (Thr34 in M4) are at van der Waals distances (3.86 and 3.97 Å in chains A and B) because the Leu158 side chain adopts a trans/gauche+ conformation. Therefore, steric hindrance between Leu158 and Thr202 might be responsible for increasing the distance between Trp33 Cα atoms and for the failure to obtain a dArmRP-peptide complex structure. To adopt a Trp33 Cα distance which is similar to the values seen in the major binding site of importin-α, Thr202 OG1 would have to move closer to Leu158, but this approach would require a gauche−/trans conformation of the Leu158 side chain. Of course, surface-exposed side chains (such as Trp33 and Glu30) also adopt different rotamers, but it can be assumed that these differences affect inter-repeat distances to a minor extent ...

Bithynia tentaculata are dioecious organisms, meaning they have two sexes. Therefore, they must undergo sexual reproduction. Female faucet snails tend to lay eggs anywhere from May to July because the temperature is above 20 C, which is a favorable temperature for typical growth (Dillon and Watson 2006). Eggs are laid in organized rows of two which can range anywhere from 1 to 77 clumps. Clumps of the eggs can be found on hard substrates such as stones. It takes about three weeks to three months for the eggs to hatch depending on the temperature. Once hatched, a faucet snail can live to be about 18 to 39 months old. The overall lifecycle for Bithynia tentacula is very rapid when compared to other snails, taking about a year to complete (EOL).. ...

Temperature is an important factor in snail control and exerts a great influence on the molluscicidal activity of this toxicant, especially when employed at concentrations of 2 to 10 p.p.m. The concentration of the snail-killing agent should be maintained for 12, and preferably 20 to 24 hours. The molluscicidal activity of the compound against Bulinus and Biomphalaria, and the eggs of the latter, in Egypt was lower than that reported for sodium-pentachlorophenate used with other species of schistosome vectors in different geographical localities and under different environmental circumstances.
Urinary schistosomosis is a serious public health problem prevalent in low-income rural regions of sub-Saharan Africa, including coastal part of Kenya. Praziquantel administration to school-aged children is the prevailing tool of schistosomosis control in these regions. The aim of our study was to find out if this control strategy can lead to interruption of parasite trasmission and disease elimination. During February and March 2018, the occurrence of urinary schistosomosis in volunteers of primary health care facilities in Kwale County, Kenya was examined and the occurrence of infected intermediate hosts Bulinus globosus in local water resources was monitored. Participants completed a questionnaire concerning source of water for household purposes, type of housing and health status and were asked to provide urine samples. Diagnosis of urinary schistosomosis was established by detection of Schistosoma haematobium eggs in urine specimens microscopically, using filtration method. Infected B. ...
The embryonated eggs are passed with urine and less commonly with stool outside the body of the definitive host. If these eggs gain access to water, ciliated miracidium larva hatches out from each egg. The larvae move freely in water in search of intermediate host, which are snails. The snails acting as intermediate host belongs to the genus Bulinus and Planobarius. The miracidium enters into the snails body by penetrating the soft tissues and ultimately reaches the liver. Inside the liver of the snail, the larva loses its cilia and within 4 to 8 weeks transform into the "sporocyst." The sporocyst multiplies to form a second generation of sporotocyst. The daughter sporocyst gives rise to forked tail "cercaria larva" which are infective stage larvae. A single miracidium produces 100,000 to 250,000 cercana. The cercaria larva breaks off from the sporocyst and finally makes its way out of the snail body mo water. Cercariae freely swims into water for 48 hours and during this period if they come in ...

Though they have no spoken language, f lail snails communicate using two different means, both completely silent. The first, an elaborate sign language of waving tentacles, is primarily used for communicating immediate needs, warnings, and other messages that are quickly picked up and passed through the rout. The second and more in-depth form of communication is a complex chemical writing system encoded within the snails slime. Every flail snail has its own unique chemical signature that makes its slime trail immediately recognizable to other snails. Within its trail, each snail records a running dialogue of its thoughts, observations, and memories in a complex interaction of scents that can linger on the stone long after the slime has dried to dust. Other snails can read this dense stream of information and edit it with their own trails, creating a vast, interwoven cultural narrative that at once contains the snails greatest art and the sum of their collective history. Together, the slime ...

Due to the potential risk that bird feeders and bird baths pose as transmission sites for Trichomonas it is recommended that these are emptied and taken down during outbreaks. Remove feeders and baths for at least two weeks to encourage birds to disperse from the area, reducing the potential for disease transmission. There is often plenty of other sources of food and water for birds during the summer months.. Clean and disinfect bird feeders and bird baths thoroughly and regularly. It is recommended that you use a weak solution of household bleach to disinfect feeders and baths. Be sure to rinse feeders and baths well and allow them to dry completely before returning them to use.. Recent research suggests that moist bird seed is a more suitable environment for hosting Trichomonas than dry seed, for this reason it is recommended that you only use bird feeders that prevent feed from becoming wet.

Five strains of Bacillus pfeifferi were isolated from a case of meningitis. These strains came from the spinal fluid, blood, nose, throat, and nasopharynx.. Immunologic reactions show no definite relations between these strains, although those from the nose, throat, and nasopharynx might be presumed to be related to one another. It is also presumable that the spinal fluid strain was derived from the upper air passages, and that the blood was invaded from the meninges. In spite of immunologic differences, it is believed that the five strains were genetically related.. The variations in these five strains from a single case are as great as those which have been found by others for strains from different cases, or individuals.. As determined by immunologic reactions, the number of so called strains of Bacillus pfeifferi is apparently limited only by the number of cultures which have been or might be isolated. It is inconceivable that under the designation Bacillus pfeifferi is included a ...

Abstract From June 1982 to May 1986 in a small village in Kwale, Kenya, we studied seasonal fluctuations in populations of Bulinus globosus, prevalence of Schistosoma haematobium infection in this snail, and effects of chemotherapy and piped water supply on infection rate of snails. In the perennially-flowing Pemba River, relatively small numbers of snails were collected; they were found only during the hot dry season (December to March). In a tributary stream, the Kadingo River, whose flow ceased at the end of both the cool and hot dry seasons, snail numbers peaked at the end of the cool dry season (October to November) and at the beginning of the hot dry season (January). Large numbers of infected snails were found in the Kadingo River from November to January (short rainy season and beginning of dry season). Selective mass chemotherapy with metrifonate and provision of piped water were begun in February and March 1984. These control measures achieved a significant reduction in the infection rate of
Schistosoma bovis is a ruminant pathogen that is poorly known at a molecular level. With an aim of identifying the parasite proteins involved in host-parasite interplay, we studied two protein extracts that contain, respectively, the proteins excreted/secreted by the adult worm (ES) and the tegumental proteins exposed to the host (TG). The 2-DE, 2-D immunoblot and MS were employed to separate and identify the antigenic proteins and the most abundant non-antigenic proteins in each extract. There were some 400 and 600 spots detected in the ES and the TG extracts, respectively. Ninety-six spots were subjected to MS analysis and 64 of them were identified. Overall, we identified 18 S. bovis proteins located at the host-parasite interface, 16 of which have not been identified previously in this parasite, and one of which -lysozyme- has never been reported in a Schistosoma species. Of the proteins identified, at least 4 can counteract host defence mechanisms. The other proteins are also likely to play ...
This paper presents a new approach to the improvement of informal settlements through limited physical interventions. The main argument in this research is that the benefits of the transformation of urban fabric should be evaluated by a deeper level of interaction between spatial configuration and socio-economic dynamics. The theoretical foundation of this claim is driven from previous research that indicate the significant role of spatial configuration in the gradual self-improvement of informal settlements. A direct implication of such findings is that limited physical interventions as a design method can be used to facilitate the self improvement of informal settlements by increasing their spatial integration to the whole of the city. Furthermore, the transformation of strategically located unplanned areas can also create a positive impact on the urban areas that surround them.. Download the full paper. ...

Mucor includes at least 39 species, belonging to phylum zygomycota, order Mucorales, Mucoraceae family. M. racemosus was first described and named by Bulliard in 1791.【1】 It is one of the earliest species people discovered in soil and was isolated long time ago--as early as 1886.【2】 M. racemosus has several synonyms such as Calyptromyces globosus, Circinomucor sphaerosporus, M.dimorphosporus f. sphaerosporus, M. globosus, M. macrosporus, M. sphaerosporus and so on. This species is closely related to M. mucedo and M.rouxianus, since they all belong to the same genus and share lots of similar characters.. ...

In ecology and genetics, a reaction norm, also called a norm of reaction, describes the pattern of phenotypic expression of a single genotype across a range of environments. One use of reaction norms is in describing how different species-especially related species-respond to varying environments. But differing genotypes within a single species may also show differing reaction norms relative to a particular phenotypic trait and environment variable. For every genotype, phenotypic trait, and environmental variable, a different reaction norm can exist; in other words, an enormous complexity can exist in the interrelationships between genetic and environmental factors in determining traits. The concept was introduced by Richard Woltereck. Scientifically analyzing norms of reaction in natural populations can be very difficult, simply because natural populations of sexually reproductive organisms usually do not have cleanly separated or superficially identifiable genetic distinctions. However, seed ...

The presence of multiple concurrent infections, or polyparasitism, is quite common in schistosomiasis endemic areas. Msambweni District in the Coast Province of Kenya is highly endemic for Schistosoma haematobium. Previous studies showed an overall prevalence of schistosomiasis in Msambweni District at 40% to 60%. This is a prevalence way above the national prevalence of approximately 23%. There has been continued support by various agencies, including the government and non-governmental organizations (NGOs) in providing treatment and control of the disease in the area. However, the long term impact of these programs in the reduction of the overall prevalence of the disease has not been fully evaluated. This survey of 1232 people aged 5-78 years in two villages in Vingujini Sub-Location Msambweni District of Coast Province, Kenya was conducted to determine prevalence of Schistosoma haematobium and soil transmitted helminthes infections. Urine and stool samples were collected and examined for ...
An irrigation system for use during endoscopic or minimally invasive surgery is shown. Both vacuum and a pressurized irrigation fluid are continually provided to a trumpet valve for immediate use during surgery. A pump that provides the pressurized irrigation fluid has a reusable motor, but a disposable head that can be replaced between procedures. A control circuit automatically reduces the voltage being supplied to the pump if there had not been a request for irrigation fluid for a first time period. If a second time period, which is longer than the first time period, passes and (a) there is no demand for irrigation and (b) the voltage to the pump has not been reduced, either the voltage to the pump will be reduced or the pump shut OFF. The irrigation system is provided in kit form with parts having to be replaced between procedures contained therein.

Impact. Giant African snails are already present in several Caribbean countries. In terms of environmental impact, the snails feed on indigenous vegetation and pose a conservation problem by altering habitat and out-competing other snails for food. For agriculture, they have become a destructive pest of crops and garden plants. To humans, they are vectors for disease, such as, eosinophilic meningitis, caused by the parasite rat lungworm that is passed to humans through eating raw or improperly cooked snails.. Control. Hand-collecting followed by proper disposal remains the safest means of control. Some programs advocate the use of snail traps, using beer as bait. Others have incorporated poisoning with molluscicides and other chemicals, and even using flame-throwers to burn snails alive, but there are safety concerns associated with these methods. Biological control backfired when the rosy wolf snail Euglandina rosea introduced to more than 20 oceanic islands and a number of Asian countries as a ...
Henry W. Parker described the Poweshiek skipper, the butterfly that this web site is named after. His wife was Helen Fitch Parker, an accomplished author in her own right. Helen wrote a book about snails which was intended for a Sunday School audience, and also included religious instruction. The book is called Rambles After Land Shells. That book can be found online here. On page 11 of that book can be found some information about Helix pulchella, and how the shell can be cleaned by boiling the animal then pulling it out of the shell. I found it amusing that I could recognize one of the snails I have photographed by her description. Other snails that I have seen are also described in fair detail in the book by her. I plan to add some pages on Helen Fitch Parker at some time in the future because she was fascinating. She did know her snails, and she did collect snails in Iowa. However, her work was probably all destroyed when Iowa Colleges (now Grinnell College) natural history museum was ...

Author SummaryConsumption of raw fish and other freshwater products can lead to unpleasant worm infections. Indeed, such worm infections are of growing public health and veterinary concern, but they are often neglected, partially explained by the difficulty of accurate diagnosis. In the present study we infected 12 mice with an intestinal worm (i.e., Echinostoma caproni) and collected blood, stool, and urine samples 7 times between 1 and 33 days after the infection. At the same time points, blood, stool, and urine were also sampled from 12 uninfected mice. These biofluid samples were examined with a spectrometer and data were analyzed with a multivariate approach. We observed important differences between the infected and the uninfected control animals. For example, we found an increased level of branched chain amino acids in the stool of infected mice and subsequent depletion in blood plasma. Additionally, we observed changes related to a disturbed intestinal bacterial composition, particularly in

Author Summary Urogenital schistosomiasis (infection with parasitic Schistosoma haematobium worms, the most common human-specific Schistosoma species globally) affects over 112 million people worldwide. S. haematobium worms primarily lay eggs in the bladder, upper urinary and genital tracts, and the host immune response to these eggs is considered to cause almost all associated disease in these organs. Resulting conditions include hematuria (bloody urine), urinary frequency, fibrosis (internal scarring) of the urinary tract, increased risk of bladder cancer, and enhanced susceptibility to contracting HIV. Approximately 150,000 people die annually from S. haematobium-induced obstructive kidney failure alone, making this species one of the deadliest worms worldwide. Despite the importance of S. haematobium, a lack of an experimentally manipulable model has contributed to the paucity of research focusing on this parasite. We have circumvented the barriers to natural S. haematobium oviposition in the mouse

Achatina fulica is hermaphroditic; each individual snail has both male and female reproductive parts. There are no distinguishing parts separating sexes because each snail contains both sex reproductive systems. They do not self-fertilize, so the snails need to mate with another snail of their species. As a Stylommatophiora, Achatina fulica does not mate randomly; the snails mate with respect to age and size of other snails. Immature, small snails that are still growing produce only spermatozoa, while larger, mature adults produce both spermatozoa and ova. There is an age dependent mate choice when it comes to young snails because they need and prefer older adults to mate with. Young giant African snails copulate at all hours of the night, while older adults mate in the middle of the night. The snails choose their mates with respect to size and age, but the reproductive stage-dependent mate is a more attractive mate than the body size-dependent mate choice. Mating occurs when one snail ...

KIWAYUU, Coastal Kenya - The story of mother-of-six Aisha Tiro Bahero, 30, is not only one of resilience and determination, but also of how access to maternal and child health services is critical in saving womens lives and empowering them to lead productive and healthy lives.. Aisha lives in Kiwayuu, a small island located in the eastern part of the Lamu Archipelago in Coastal Kenya. The only health facility on the island was established two years ago by the Lamu County Government, and it serves 600 inhabitants. Prior to its inception, patients, including expectant mothers would travel to Lamu Island, a seven-hour trip by dhow or an hours trip by motorboat.. "I got married when I was barely 18 years old and I delivered my first child at home," says Aisha. Her three subsequent deliveries also took place at home.. "As a marginalized community, we were ignorant about the importance of antenatal care, largely because we didnt have a health facility in Kiwayuu.". The community relied heavily on ...

Informal settlements (slum-areas) are often considered a transient phenomenon and an outcome from economic hardship which will ease once the national economy improves. This has however proven to be a myth rather than reality. Instead, different forms of informal settlements in and around cities are constantly growing worldwide. Access and affordability to infrastructure services such as water, sanitation, energy and communication is essential for sustainable development and poverty eradication. Even so, the living conditions for people in these areas are far below an acceptable level.. This report presents the result from a study on infrastructural issues in informal settlements in East Africa. The aim of the study was to identify indicators within the infrastructural sector that are of special concern for vulnerable groups, such as female-headed households. An additional aim was to apply and test a method for participatory documentation - photo eliciting.. The study targeted two informal ...

Background: Schistosomes are parasitic worms that dwell in the blood vessels and belong to the genus Schistosoma. Schistosoma haematobium, one of the species of Schistosoma cause urogenital schistosomiasis (urinary schistosomiasis). The knowledge of urogenital schistosomiasis has improved over the years; however, there are still endemic areas with reported cases in Africa including Ghana. The disease may present as mild or severe with accompanying morbidity and mortality. Genetic variation in S. haematobium may play an important role in developing pathology which may lead to difference in severity in clinical symptoms. Aim: The aim of this study was to determine a possible link between genetic variations in S. haematobium, and disease severity in the Greater Accra Region. Methodology: Three hundred and sixty-seven (367) urine samples were collected from school children in Zenu and Weija communities. Presence of S. haematobium eggs was determined microscopically from the urine deposit after ...
Prostephanus truncatus (Horn) is a pest of stored maize that has caused major problems since appearing in Africa, though it is regarded as a minor pest in Mexico and Central America. The ability of P. truncatus to feed and breed on a great variety of environments, raises the questions to whether this beetle can break down starch and cellulose. The digestive system of P. truncatus may explain its host range. The digestive systems of adults and larvae of three P. truncatus strains from different geographic regions (Mexico, Togo, and Tanzania) were the subjects of the present work. The anatomical study of the digestive system of P. truncatus shows that the guts of adults and larvae were externally different and that these differences reflect different life spans and their different feeding habits. The internal anatomy, is similar, with the exception of the presence of peritrophic membrane and glycogen-like granules in the midgut of the adult stage. There is a cryptonephric system present in both ...

Market Research Report: Water Supply & Irrigation Systems Industry. Date: Nov 2017 Flowing water: The industry will consolidate, bolstering operating efficiency and revenue growth
Prior work has demonstrated the ability of common property systems to sustain institutional arrangements governing natural resources over long periods of time. Much of this work has focused on irrigation systems where upstream users agree to management arrangements that distribute water resources across both upstream and downstream users. A series of design principles have been identified that tend to lead to long-term sustained water management in these types of irrigation systems. However, this prior work has focused on the aggregate outcomes of the water system, and there has been little work evaluating the heterogeneity of water delivery within irrigation systems in developing countries. Heterogeneity of water resources within these systems has implications for livelihood outcomes because it can be indicative of a social, technological, and/or biophysical element facilitating or detracting from water delivery. We present a multilevel analysis of households nested within 25 smallholder ...

8. Irrigation: I highly recommend a built in easy and effective irrigation system for use during dry periods. I have a network of small PVC pipes that I lift to work the soil every spring and then bury prior to planting. (Here are pictures.) It works great. I have a computer controlled system that I use to irrigate early in the day. This promotes the drying of leaves and decreases pests that thrive in moist conditions. (Next year, my hope is to attach a rain barrel my irrigation system. What fun ...
Its so rare, it is classed as Near Threatened. Lurking in the densely matted vegetation at the margins of the reens and ditches, this diving beetle waits to pray on snails that come too close. At nearly 40mm long and stoutly built, its a beetle that rightly deserves its regal name.

Following up on Lindas earlier comments about potential problems with TreeGators, my summer interns and I did a random spot check of about 150 TreeGators currently in use on the MSU campus. As background, MSU Landscape Services plants about 1,200 trees and shrubs each year. All newly-planted trees which are not on an automatic irrigation system are fitted with one or two TreeGators, which are filled from a water wagon every week or every two weeks, depending on weather. Conifers and multi-stemmed trees are fitted with Tree-Tubes, another style of irrigation bag that fits like an inner-tube around the base of a tree. At MSU irrigation bags are usually left on trees during the first growing season. Presnetly there are over 1,000 irrigation bags in use on the MSU campus.. During our spot-check, we found few items I would consider to be a major concern. We found 25 trees with mold or saprophytic fungi growing in the mulch under the bags. While unsightly, these are unlikely to cause major tree ...

The Sahelian goat is a breed of goat from West Africa, used mainly for meat and skin production. It is also known by some other names such as Cheèvre bariolée, Fulani, Gorane, Nioro, Niafounké, Sahélienne, Sahel, and West African Longlegged. The Sahelian goat belongs to the Savanna group of goats with many types and subtypes raised in the Saharan and sub-Saharan region. Sahelian type of goat is distributed in north and northwest of Mali. The Sahelian goat is most suited to desert or semidesert environments and is intolerant of areas with high humidity. The breed is widely distributed in the arid and semiarid zones of the Sahel, north of 12°N from central Chad in the east to the Atlantic coast in the west and well into the southern Sahara. This is the most suitable place, where most of the worlds Sahelian goats are found, although some numbers of this goat breed can also be found elsewhere in the world, especially in such areas where suitable environments or conditions are available, such ...
Many morphological and life-history traits show phenotypic plasticity that can be described by reaction norms, but few studies have attempted individual-level analyses of reaction norms in the wild. We analyzed variation in individual reaction norms between laying date and three climatic variables (local temperature, local rainfall, and North Atlantic Oscillation) of 1126 female collared flycatchers (Ficedula albicollis) with a restricted maximum likehood linear mixed model approach using random-effect best linear unbiased predictor estimates for the elevation (i.e., expected laying date in the average environment) and slope (i.e., adjustment in laying date as a function of environment) of females reaction norms. Variation in laying date was best explained by local temperature, and individual females differed in both the elevation and the slope of their laying date-temperature reaction norms. As revealed by animal model analyses, there was weak evidence for additive genetic variance of elevation (h2 +/
Most of us are trying to live within our budgets while also trying to take better care of Gods earth. One way that we can do well by our planet and our wallets is to water more plants with less water. We can do this by installing a drip irrigation system in our gardens. Drip irrigation is up to 15 percent more efficient than sprinkler systems. They can also reduce diseases associated with high levels of moisture on some of your plants. Another benefit from having a drip system is that it can save us time in our watering chores, thats a win-win that we all can use!. Drip systems, also called trickle irrigation, work by slowly putting water into the soil. This slow, ground-level watering allows for less evaporation of the water, thus making sure that more of it gets to the roots of your plants, right where it is needed.. All of this was what I had in mind for my garden this year, so I hired my brother to lay out and install my new system. But, due to unforeseen circumstances, he was unable to ...
Completed in 1908, McDougall Centre was originally the Calgary Normal School and later became a public school. Constructed in the Beaux-Arts style, McDougall Centre became a historic site in 1982. Today, it is the southern headquarters and conference centre for the Government of Alberta located in downtown Calgary. The irrigation system of the centre was constructed in 1983, however, the system on the East side was replaced around 2005. The irrigation water service is in an underground chamber, and the irrigation controller is in a utility room on the West side of the building. There are multiple battery operated controllers in the field. LIS was hired by Alberta Infrastructure to audit the existing irrigation system and to provide short and long term recommendations.. ...
Ogah C.N, Ogbu O, Nwuzo A.C, Okonkwo E.C, Afiukwa F.N, Iroha I.R, Ugbo E.N, Ilang D.C, Ejikeugwu P.C*. ABSTRACT. Schistosomiasis is a parasitic disease caused by the trematode worm Schistosoma haematobium; and its transmission usually takes place only in places where fresh water snail vector is present and where there is contact between the population and infected water. The disease is commonly observed in most tropical countries; and it is a serious public health problem that needs concerted efforts to contain its spread or occurrence in any given community. A total of 240 freshwater snail specimens were collected from three different sampling sites (ponds near schools, market and farmland areas). Twenty freshwater snails were collected from each of the given locality within the four selected local government area of Ebonyi State. The specimens were analysized using biological and Microbiological Standard techniques. Out of the 240 freshwater snails collected, 200(83.33%) were identified ...

Downloadable! Policies of devolving management of resources from the state to user groups are premised upon the assumption that users will organize and take on the necessary management tasks. While experience has shown that in many places users do so and are very capable, expansion of co-management programs beyond initial pilot sites often shows that this does not happen everywhere. Yet, much is at stake in this, with more widespread adoption of irrigation management transfers and other forms of community-based resource management. It is therefore important to move beyond isolated case studies to comparative analysis of the conditions for collective action. This paper identifies factors affecting organization of water users associations, and collective action by farmers in major canal irrigation systems in India, based on quantitative and qualitative analysis of a stratified sample of 48 minors in four irrigation systems (two each in Rajasthan and Karnataka).
