Mycoflora of grain maize (Zea mays L.) Stored in traditional storage containers (Gombisa and sacks) in selected woredas of Jimma zone, Ethiopia

Mycoflora of maize (Zea mays L.) grain (Variety: Bako Hybrid-660) stored in two traditional storage containers (Gombisa and Sacks) for 180 days was studied for mycoflora in two agro-ecologies, that is Intermediate and Lowland, with altitude ranges of 1500-2500 meters above sea level, and 1000-1500 meters above sea level, respectively, in Jimma zone, Ethiopia. The temperature and relative humidity were observed for identifying fungi species which can flourish and cause maximum deterioration to maize grains. Significant (P<0.05) decreases in germination rate of the grains were observed with time under each storage method for both the low and intermediate altitude ranges. Germination percentage reduced from 98% and 97.5% to 68.5% and 80.5% for grains stored in Gombisa and Sacks, respectively. Storage type significantly (p<0.05) affected seed germination under intermediate agro-ecology whereas no significant (p>0.05) effect was observed under lowland agro-ecology due to storage container type. One sterile white mycelium and a total number of eight species of fungi viz., Aspergillus flavus, Aspergillus fumigatus, Aspergillus niger, Aspergillus tereus, Cladosporium cladosporioides, Drechslera halodes, Fusarium oxysporum and Penicillium chrysogenum were identified from maize grain at the beginning and during storage. The most common fungi recorded from both agro-ecologies in the two storage structures were A. flavus, A. niger, D. halodes and F. oxysporum. These fungi were recorded from 90, 51, 72 and 44 percentage of the seed samples, respectively. In the districts of both intermediate and lowland agro-ecology these fungi were consistently recorded throughout 180 days, during storage. A. fumigatus was detected in3.6% of samples while C. cladosporioides observed in 15% of the samples. Fungal species A. tereus and Penicillium were recorded in 0.5% of samples in selected districts of Jimma. These fungal species were known to cause deterioration of maize and are a health risk to humans and animals due to the toxins they potentially produce.Key words: Agro ecologies, Fungi, Maize, Storag

The pathogenesis and immune evasive mechanisms of equine herpesvirus type 1

Equine herpesvirus type 1 (EHV-1) is an alphaherpesvirus related to pseudorabies virus (PRV) and varicella-zoster virus (VZV). This virus is one of the major pathogens affecting horses worldwide. EHV-1 is responsible for respiratory disorders, abortion, neonatal foal death and equine herpes myeloencephalopathy (EHM). Over the last decade, EHV-1 has received growing attention due to the frequent outbreaks of abortions and/or EHM causing serious economical losses to the horse industry worldwide. To date, there are no effective antiviral drugs and current vaccines do not provide full protection against EHV-1-associated diseases. Therefore, there is an urgent need to gain a better understanding of the pathogenesis of EHV-1 in order to develop effective therapies. The main objective of this review is to provide state-of-the-art information on the pathogenesis of EHV-1. We also highlight recent findings on EHV-1 immune evasive strategies at the level of the upper respiratory tract, blood circulation and endothelium of target organs allowing the virus to disseminate undetected in the host. Finally, we discuss novel approaches for drug development based on our current knowledge of the pathogenesis of EHV-1

Never look a gift horse in the mouth or should you? Upgrading the Hare irrigation system in Southern Ethiopia

The upgrading of the Hare Irrigation System was a joint undertaking of the governments of Ethiopia and the People's Republic of China. After completion of the primary and the secondary canals, farmers refused to take over responsibility of the system. Existing literature on the Hare Irrigation System does not differentiate between various farmer groups and their interests. This study highlights the differences in perception of head-end, middle and tail-end farmers. The main group that is not satisfied with the system are the head-enders, because they are partly excluded from using it. While the middle and tail-end farmers are satisfied with the new irrigation system, they are unhappy because they have not received the promised compensation. Overall, the paper highlights the lack of transparency and communication between the local community, the government and the Chinese design and construction agency, which appears to be the main reason for the dissatisfaction of parts of the local community

Burnout among healthcare providers in the complex environment of the Middle East: a systematic review

Background Burnout is a syndrome characterized by emotional exhaustion, increased depersonalization, and a diminished sense of personal accomplishment due to chronic emotional stress at work. Burnout impacts job satisfaction, job performance, vulnerability to illnesses, and interpersonal relationships. There is a gap in the systematic data on the burden of burnout among healthcare professionals from different sectors of healthcare in Middle Eastern countries. Our objective was to examine the burden of burnout among healthcare providers in the Middle East, how it was assessed, which sectors were included, and what interventions have been used. Methods Articles were found through a systematic review of search results including PubMed, Web of Science (Thomson Reuters), and PsycINFO (EBSCO) using search terms reflecting burnout in Middle Eastern countries among populations of healthcare providers. Studies were included if they examined a quantitative measure of burnout among healthcare providers in the Middle East. Results There were 138 articles that met our inclusion criteria for this systematic review. Studies focused on burnout in the Middle East among physicians (N = 54 articles), nurses (N = 55), combined populations of healthcare workers (N = 22), and medical students (N = 7). The Maslach Burnout Inventory was the most common tool to measure burnout. Burnout is common among physicians, nurses, and other healthcare professionals, with prevalence estimates predominantly ranging between 40 and 60%. Burnout among healthcare providers in the Middle East is associated with characteristics of their work environments, exposure to violence and terror, and emotional distress and low social support. Conclusions Burnout is highly prevalent among healthcare providers across countries in the Middle East. Previous studies examining burnout in this region have limitations in their methodology. More thoroughly developed epidemiologic studies of burnout are necessary. Health system strengthening is needed in a region that has endured years of ongoing conflict, and there is an urgency to design and implement programs that tackle burnout among health professionals
