Egg induced inflammation in the seminal vesicles and the prostate could be underlying mechanism for both observations. The bird schistosomes are a group of blood flukes Platyhelminthes, Digenea. They contain the largest clade of the family Schistosomatidae that includes ten genera: Dendritobilharzia , Gigantobilharzia , Allobilharzia , Austrobilharzia , Anserobilharzia , Trichobilharzia , Bilharziella , Macrobilharzia, Ornithobilharzia and Jilinobilharzia. In the two-host life cycle fresh water snails as intermediate hosts and aquatic birds as definitive hosts , they develop as adults with in venous and arterial vessels or nasal tissue of their bird host.
Cercariae of the bird schistosomes released from intermediate hosts are recognized as the great causative agent of human cercarial dermatitis HCD or Swimmer's itch which is considered an emerging disease in various parts of the World de Gentile et al. Experiments have demonstrated that avian schistosomes can migrate and partly develop in other bodies of their non-specific mammalian hosts, causing serious health risks. Therefore, as a result of these experiments, It is thus considered conceivable that avian schistosomes may be responsible for some nervous or pulmonary symptoms in humans In I became sick while working overseas in the Middle East with a fever, frequent urination along with kidney and bladder pain plus a long list of other health related problems due to parasites.
I returned home gave the disease to my wife and we battled it together. It took me 6 years to finally figure out what was wrong with me as I was diagnosed with Schistosomiasis in We spent another 2 years trying to figure out how to cure her and remove it from her reproductive tract. I am working to bring it to market as fast as possible for those who are suffering.
Parasite Information. What is Schistosomiasis? Also known as Snail Fever and Bilharzia this is a disease caused by parasitic flatworms called schistosomes. In children, it may cause poor growth and learning difficulty. Where is Schistosomiasis found? How is Schistosomiasis transmitted? How does it affect you?
Symptoms of Schistosomiasis. A red rash or bumps on the skin from being exposed to infected water usually visible in 12 hours after exposure If contracted sexually symptoms show in hours after exposure with frequent urination similar to an UTI.
Diarrhea — schistosome eggs can lodge in the blood vessels of the intestine causing inflammation resulting in bloody diarrhea or diarrhea. Constipation Joint pain Headache Neck pain Frequent urination of clear urine every 2 hours Constant urge to urinate even after evacuating bladder Pain when urinating — schistosome eggs lodged in the urinary tract cause inflammation and blood in the urine resulting in symptoms similar to urinary tract and bladder infections.
Blood in urine Burning or stinging after urinating Urine containing thin black threads Dyspareunia pain during intercourse Vagina pain Vaginal discharge thick white fluid Kidney pain Bladder pain Low Seminal fluid or semen Yellow chunks in sperm Hemospermia blood in sperm Burning after ejaculation All symptoms come and go as this is a chronic disease, usually on a 6 week cycle Sometimes acute schistosomiasis symptoms can be so mild they go unnoticed If left untreated death rate is about , people per year Bladder cancer specifically with Schistosomiasis Haematobium.

The building of the Aswan High Dam -which was completed in — did not cause any increase in schistosomiasis prevalence. In , a study conducted in nine governorates of Egypt confirmed the change in the pattern of schistosomiasis transmission in the Delta.
There was an overall reduction in S. In Middle and Upper Egypt there was consistent reduction in the prevalence of S. However, foci of S. All schistosomiasis control projects implemented in Egypt from to adopted the strategy of transmission control and were based mainly on snail control supplemented by anti-bilharzial chemotherapy.
It adopted morbidity control strategy with Praziquantel mass treatment as the main component. Schistosomiasis is a parasitic disease caused by the digenetic trematodes of the genus Schistosoma members which are commonly known as blood flukes. Schistosoma haematobium was discovered by Theodore Bilharz in during autopsy at Kasr El Ainy hospital [1].
In , the life cycle of the Schistosome parasite was first described by Leiper [2]. Schistosomiasis comes after malaria among parasitic diseases as regards the number of people infected and those at risk of infection [3]. There are two major forms of schistosomiasis —intestinal and urogenital-caused by five species of the parasite.
Intestinal schistosomiasis is caused by four species namely: Schistosoma mansoni S. On the other hand, S. In the absence of accurate epidemiological data, estimates must still be used to determine the possible burden of infection due to schistosomiasis. On the basis of extrapolating the national prevalence data obtained from the world atlas of schistosomiasis and applying it to population estimates, it was calculated that about million people would be at risk and million would be infected.
Although successful control projects have been implemented in the last 50 years, yet neither the number of endemic countries nor the estimated number of people infected or at risk of infection were reduced [5].
Ruffer in , was the first to diagnose S. He recovered calcified schistosome eggs from two Egyptian mummies of the 20th Dynasty [6]. Calcified schistosome ova were identified radiologically in several mummies from later periods [7]. The radiological examination also strongly suggested that the calcified bladders in two other mummies were due to S. Scott, , was the first to describe the pattern of S.
His conclusions were based on two series of data which seemed to harmonize fairly well. The first were data obtained from 2 million samples collected by the Endemic Diseases section of the Public Health departments.
On the basis of the distribution of the human schistosomes, Scott divided Egypt into four regions the first region is the Northern and Eastern parts of the Delta, the second is the Southern part of the Delta while the third and fourth parts are in the Nile Valley South of Cairo.
The third part is areas with perennial irrigation system and fourth part is areas with basin irrigation. In the first region, the Northern and Eastern parts of the Delta, S. In the second region, the Southern part of the Delta, S. No topographic, hydrographic or demographic differences between these regions could be noted, although the line of demarcation was very sharp as far as the prevalence of the parasite was concerned.
The third and fourth regions were in the Nile Valley South of Cairo and there, the snail intermediate host of S. In the third region — where perennial irrigation was used — S. In the fourth region -areas with basin irrigation — S. Scott observed that the snails were much more abundant where perennial irrigation furnished canals and ditches containing water throughout the year while with basin irrigation most of the breeding places were alternatively swept by the annual flood and desiccated in the hot summer.
This led him to conclude that the change in the system of irrigation in Upper Egypt was responsible for the increase in S. Furthermore, Azim, and Khalil and Azim, demonstrated the impact of converting the basin irrigation system to perennial irrigation in Upper Egypt on the transmission of schistosomiasis haematobium [11,12]. Similarly, El Zawahry reported that the construction of the perennial irrigation system in old Nubia led to a remarkable increase in S. Both S. However, S.
Furthermore, in , studies conducted in eight villages in Qalubeia governorate reported obvious changes in the pattern of transmission of schistosomiasis prevalence during the previous two decades. The prevalence of S. These findings led to the design of two cross-sectional surveys of the population of the Nile Delta in and [17,19]. The two surveys included the study of 71 villages, one village from each of the 71 districts comprising the eight governorates of the Nile Delta.
The authors attributed the overall increase in prevalence in to the use of more sensitive diagnostic tests. The relative sensitivity of the diagnostic techniques used in the two surveys must be considered. Scott used the Stoll and Hausheer dilution technique [20] while the Kato technique [21] was used in the study. The effective amount of stools examined was 5 mg in study as compared to the 43 mg in study.
The Kato technique proved to be more sensitive than the dilution technique. The authors Cline et al. On the other hand, there was a striking decrease in S. Mickelson et al. As regards the Middle and Upper Egypt governorates, it is obvious that there was consistent reduction in the prevalence of S. In addition a number of communities with high prevalence of S. Foci of S. Consequently, The National Schistosomiasis Control Program has formulated objectives to prevent the further spread of S.
In , an extensive national house to house survey similar to the one conducted by Scott in was conducted to investigate the prevalence and intensity of infection with schistosome species, the prevalence and magnitude of morbidity caused by schistosomiasis, the changing pattern of distribution of S.
A random sample of the rural inhabitants of nine governorates selected as representative of each area Upper and Lower Egypt and of governorates with both high and low infection rates [26]. Although the study was conducted over a period beginning in and ending in [26] , yet the results were published in [22,26] except for Kafr El Sheikh KES governorate which was published in [27].
In Upper Egypt governorates, where S. Although this survey did not include Giza, yet another study carried out in one of the villages of this governorate indicated that the estimated prevalence of S. On the other hand, the prevalence of S. In conclusion, the study of the nine governorates of Egypt confirmed the already documented change in the pattern of transmission of both species of schistosome infection in Upper and Lower Egypt [22].
The detailed data are presented in Tables 1 and 2 and Fig. Prevalence of S. Prevalence S. In general, two main factors were responsible for the pattern of schistosomiasis infection in Egypt. The first factor is the irrigation used whether basin or perennial. The change from basin to perennial irrigation was the result of the construction of the Aswan High Dam. The second was the control programs implemented by the Egyptian Ministry of Health. Since both these factors played a vital role regarding the situation of schistosomiasis infection, they will be discussed in details under separate topics later.
Antibody detection can be useful to indicate schistosome infection in patients who have traveled in schistosomiasis endemic areas and in whom eggs cannot be demonstrated in fecal or urine specimens.
Test sensitivity and specificity vary widely among the many tests reported for the serologic diagnosis of schistosomiasis and are dependent on both the type of antigen preparations used crude, purified, adult worm, egg, cercarial and the test procedure. At CDC, a combination of tests with purified adult worm antigens is used for antibody detection. A positive reaction indicates infection with Schistosoma species. However, cross-reaction with S. The presence of antibody is indicative only of schistosome infection at some time and cannot be correlated with clinical status, worm burden, egg production, or prognosis.
