Dirofilariasis by Dirofilaria repens: an imported case and a brief review

Human infections caused by Dirofilaria repens, a cosmopolitan zoonotic parasitosis endemic in Southern and Eastern Europe and Asia still is an underdiagnosed infection due to parasite identification difficulties.

Detection of Wolbachia in Dirofilaria infected dogs in Portugal

Wolbachia pipiens, an intracellular endosymbiont bacteria of filarial nematodes, has been implicated in the pathogenesis of filarial diseases, in particular in heavy Dirofilaria spp. infections. Antibiotic therapy (doxycycline) against Wolbachia has been proven to be suitable adjunct therapy, prior to adulticide treatment of canine dirofilariosis.

Schistosomiasis and Acute Appendicitis

Acute appendicitis associated to Schistosoma haematobium and S. mansoni infection has been found in patients submitted to urgent appendectomy at the Hospital Américo Boavida in Luanda. Due to the high prevalence and morbidity caused by schistosomiasis (or bilharziasis) in the country, we suspect that the involvement of Schistosoma infection on appendicular pathology could be very frequent, in particular for those individuals more exposed to the parasite transmission.

Prostate adenocarcinoma associated with prostatic infection due to Schistosoma haematobium. Case report and systematic review

We describe the first case of a prostate adenocarcinoma associated with prostatic Schistosoma haematobium infection occurring in Angola. Prostate carcinoma was suspected because of high levels of prostate-specific antigen. This observation prompted us to review the literature on schistosomiaisis with respect to genital pathology and prostate cancer.

The role of the immunological background of mice in the genetic variability of Schistosoma mansoni as detected by random amplification of polymorphic DNA

Schistosomiasis is a parasitic disease caused by flatworms of the genus Schistosoma. Among the Schistosomaspecies known to infect humans, S. mansoni is the most frequent cause of intestinal schistosomiasis in sub-Saharan Africa and South America: the World Health Organization estimates that about 200,000 deaths per year result from schistosomiasis in sub-Saharan Africa alone. The Schistosoma life cycle requires two different hosts: a snail as intermediate host and a mammal as definitive host.
