A system of homogeneous equations with a time delay is used to model the population dynamics of schistosomes. The model includes the parasite's mating structure, multiple resistant schistosome strains, and biological complexity associated with the parasite's life cycle. Invasion criteria of resistant strains and coexistence threshold conditions are derived. These results are used to explore the...

A pluriparus full-term exhausted murrah buffalo aged about 8 years, in its 3rd parity escorted to the TVCC, College of Veterinary Science and Animal Husbandry, ANDUAT, Ayodhya, India, with history straining since last 12 h. On per vaginum examination, this case was diagnosed as dystocia because true Schistosoma reflexus. successful per-vaginal management due Schistosomus reflexus monster by tra...

204 Objective: Hepatitis C virus (HCV) infection with concurrent Schistosoma mansoni infestation has emerged as a major cause of chronic liver disease and liver cirrhosis. The aim of this study was to investigate the prevalence of HCV among bilharzia patients. Method: The study was conducted at the Viral Diagnostic and Parasitology Departments, Regional Laboratory and Blood Bank, Dammam, Kingdo...

Schistosomiasis mansoni is a systemic disease caused by a helminth of the schistosoma genus. The disease is generally asymptomatic or gastrointestinal symptoms may predominate. Skin lesions related to the disease are rarely diagnosed, even in endemic areas. The authors report the case of a young girl diagnosed with cutaneous schistosomiasis with involvement of the abdomen, back and scapular reg...

As of 16 May 2014, eleven cases (six from France and five from Germany) of uro-genital schistosomiasis have been reported. All cases were exposed to the same natural swimming area in southern Corsica without known exposure to fresh water in an endemic area of Schistosoma. This is the first locally acquired infections of Schistosoma haematobium in France. The disease is known to be very focal in...

Methods and materials A multidisciplinary study was conducted in two neighboring rural communities in northern Senegal, where S. mansoni and S. haematobium are co-endemic (n=857). Kato-Katz and urine filtration were used for microscopic detection of the respective Schistosoma species. Households were located using handheld differential global positioning system in the largest community (n=599),...

Chronic kidney disease (CKD) and end-stage renal disease (ESRD) represent a spectrum of impaired immunity with effects on cellular immunity, soluble immune factors, and inflammation. As a result, infections due to impaired immune system responses are responsible for significant morbidity in patients with kidney disease. Because of immune dysfunction in CKD, these patients have reduced probabili...

Although schistosomiasis is a widespread infection in the tropics, travellers are almost exclusively infected in sub-Saharan Africa, through exposure to freshwater infested with cercariae of either Schistosoma mansoni (intestinal schistosomiasis) or Schistosoma haematobium (urinary schistosomiasis) [1]. Primary infection may cause a febrile hypersensitivity reaction occurring three to 12 weeks ...
