Schistosoma haematobium is a biocarcinogen of human urinary bladder (UB). The present study investigated developing UB cancer mouse model by injecting S. haematobium eggs into the bladder wall and introduction of chemical carcinogens. Histopathological findings showed mild hyperplasia to epithelial vacuolar change, and high grade dysplasia. Squamou...

An assessment of the malaria prevalence and some of its risk factors was conducted in the Finchaa Sugar Factory estate, western Ethiopia, based on analysis of retrospective data from the health center, a cross-sectional survey using blood slides and a questionnaire. Over the period 2001 to 2005 average prevalence among suspected patients at the hea...

A cross-sectional retrospective survey using the past five years clinical records (2005–2009) was conducted. The study was aimed at assessing the status of common intestinal parasites from Bale-Robe Health Center, Southeastern Ethiopia, in 2009/2010. The survey involved collection of data recorded on intestinal parasite from the health center durin...

Background:-Family planning does have a wider view, dealing with birth control, reproductive health, as well as premarital and pre conception counseling. Understanding why people do not use family planning is critical to address unmet needs and to increase contraceptive use. Studies showed that 38% and 78% of the potential demand for family plannin...

Objective In this study, we aimed to assess the epidemiological profile and associated risk factors of malaria in Boset District using clinical records from the Boset District Health Office Central Surveillance Unit, East Shawa Zone, Oromia, Ethiopia. Methods This health facility-based retrospective cross-sectional study included clinical malaria...
Article
Background: Malaria is an infectious disease caused by Plasmodium parasites. Of the five human malaria parasites Plasmodium falciparum and Plasmodium vivax are the two co-endemic predominant and widely distributed species in Ethiopia, with major public health importance. Even though enormous effort has been made countrywide to reduce the disease b...

Vector-borne emerging and re-emerging diseases pose considerable public health problem worldwide. Some of these diseases are emerging and/or re-emerging at increasing rates and appeared in new regions in the past two decades. Studies emphasized that the interactions among pathogens, hosts, and the environment play a key role for the emergence or re...

Background: Diabetes mellitus (DM) is one of the emerging public health problems in developing countries. Patients with acute complications of the disease frequently seek care in hospital emergency departments. However, the magnitude of acute complications of DM has not been studied at facility levels. This study was aimed at assessing the prevalen...

Schistosomiasis is a major public health problem in Ethiopia. Currently, the prevalence of the disease can possibly be heightened due to man-made ecological transformations particularly related to the recent development programs involving irrigation and construction of dams. The expansion of some of the water resource development projects has been...
Article

A reduction in the burden of schistosomiasis is potentially achievable by integrating a schistosomiasis vaccine with current control measures. Here, we determine parasite-specific in vitro responses of B, T, and NK cells from naive uninfected rhesus macaques to Schistosoma mansoni (Sm) egg (SmEA) and worm antigen (SmWA) preparations isolated from i...
Chapter
Resulting from ingestion of inappropriately prepared or stored foods containing pathogenic viruses, bacteria, fungi and parasites, foodborne infections have become a significant source of human morbidity and mortality worldwide in recent decades. This may be largely attributable to the remarkable popularity of convenient, ready-to-eat food products...
