The development of tolerance in Pseudomonas putida DOT-T1 to toluene and related highly toxic compounds involves short- and long-term responses. The short-term response is based on an increase in the rigidity of the cell membrane by rapid transformation of the fatty acid cis-9,10-methylene hexadecanoic acid (C17:cyclopropane) to unsaturated(More)
We describe a change in epidemiology of 3,615 cases of malaria in a rural area in Ethiopia (from September 11, 1998, through September 10, 2003). The Plasmodium falciparum infection increased from 40.9% in the first year to 73.4% in the last year, and the Plasmodium vivax infection decreased from 54.7% to 22.4% (p < .001).
BACKGROUND Human immunodeficiency virus type 1 (HIV-1), hepatitis B virus (HBV), human T-cell lymphotropic virus type 1 (HTLV-1) and Treponema pallidum represent major public health problems in sub-Saharan countries. These infections can be transmitted from mother to children and may cause severe morbidities in their offspring. Ethiopia is among the(More)
BACKGROUND Many DOTS experiences in developing countries have been reported. However, experience in a rural hospital and information on the differences between children and adults are limited. We described the epidemiology and treatment outcome of adult and childhood tuberculosis (TB) cases, and identified risk factors associated with defaulting and dying(More)
In Ethiopia, malaria is caused by Plasmodium falciparum and Plasmodium vivax, and anti-malarial drug resistance is the most pressing problem confronting control of the disease. Since co-infection by both species of parasite is common and sulphadoxine-pyrimethamine (SP) has been intensively used, resistance to these drugs has appeared in both P. falciparum(More)
The aim of this study was to analyze the association of intestinal parasitic diseases with age and gender in patients with diarrhea attending a rural hospital in southern Ethiopia in the period 2007-2012. A total of 32,191 stool examination was performed in patients who presented with diarrhea. The overall prevalence of intestinal parasites in the present(More)
OBJECTIVES Skin diseases, especially tinea capitis, represent some of the most frequent causes of morbidity in developing countries. The aim of this study was to examine the prevalences of fungal infections in schoolchildren in a primary school located in a rural area in southern Ethiopia and to perform an analysis of the risk factors associated with tinea(More)
Plantar ulcers, which commonly occur in leprosy patients, tend to recur increasing physical disability. The aim of this study is to identify both the bacteriological profile of these ulcers and the antibiotic susceptibility of the isolated bacteria. 68 leprosy patients with chronic ulcers attending the in-patient department of Gambo General Hospital, West(More)
