Tree species demographics and dynamics in the native forest at Wondo Genet College of Forestry and Natural Resource Management, central Ethiopia

The extent and ecological integrity of native forests in Ethiopia have been greatly diminished during the past century. Native forests continue to be threatened by conversion to agricultural fields or plantations of non-native tree species, by excessive harvesting and wood collection, and by climate change. Due to a paucity of research, we know little about the ecology of most native forest species, about the overall dynamics of native forest communities, or about the capacity of individual native tree species to respond to current and future threats. A group of students and faculty at Wondo Genet College of Forestry and Natural Resource Management in central Ethiopia examined the demography of two common tree species in a 8-ha tract of native forest located on the College campus. Numbers and diameters of Podocarpus falcatus and Croton macrostachus were tallied in six 200-600 m2 plots. The size class distribution of Podocarpus resembled an inverse J form, with a preponderance of smaller stems but some large individuals up to 226 cm dbh--indicative of a relatively stable population capable of regenerating beneath the established forest canopy. In contrast, most Croton were 20-50 cm dbh, with only a few larger or smaller individuals--reflecting a discrete pulse of regeneration, probably following a local disturbance that created gaps in the forest canopy. These results suggest that the shade-intolerant Croton is more resilient to clearing or harvesting than is the shade-tolerant Podocarpus. However, key questions remain, notably the date and nature of the disturbance that produced this documented pulse of Croton regeneration, the optimal and maximum size of opening can be colonized by Croton, and whether Podocarpus regeneration is restricted to intact canopy settings (as suggested by these findings) or if this species can regenerate in openings as well.National Science Foundation

Digestibility and Feed Intake of Menz Sheep Fed Natural Pasture Hay Supplemented with Ameja (Hypericum quartinanum) Leaf and Noug (Guizotia abyssinica) Seed Cake

The experiment was conducted to evaluate the effect of supplementation of different  proportion of Ameja (Hypericum quartinanum) leaf (AL) and Noug (Guizotia abyssinica) seed cake (NSC) on digestibility and  feed  intake of Menz sheep. Twenty five yearling male Menz lambs were divided based on their initial body weight (BW) and randomly assigned to treatments. Treatments were natural pasture hay (NPH) ad libitum + 150 g/day oats grain alone (T1) or with 344 g/day AL (T2), 230 g/day AL + 50 g/day NSC (T3), 112 g/day AL + 100 g/day NSC (T4) and 150 g/day NSC (T5). The supplements from AL and NSC were on iso-nitrogenous basis. The crude protein (CP) content of NPH, NSC, AL and oat grain was 6.5, 35.6, 15.1 and 9.8%, respectively. Total dry matter (DM) intake was greater for T3, T4, and T5 as compared to T1. There was significant difference among treatments in CP  intake and its digestibility differed (P < 0.001) among the  treatments but not for DM and other nutrients. Thus it is advisable to use Noug seed cake alone or Ameja/Noug seed cake combination at 67:33 proportion as protein supplement, whenever Noug seed cake is available. However, when Noug seed cake is unavailable or expensive, Ameja leaf can be used as a sole protein supplement. Keywords: Menz Sheep, Intake, Digestibility, Ameja, Noug, Crud protein

Health Extension Workers' diagnostic accuracy for common childhood illnesses in four regions of Ethiopia: a cross-sectional study.

AIM: The Ethiopian primary care of sick children is provided within the integrated Community Case Management of childhood illnesses by Health Extension Workers (HEW). There is limited knowledge whether this cadre correctly assess and classify common diseases. The aim was to study their ability to correctly classify common childhood illnesses. METHODS: A survey was conducted from December 2016 to February 2017 in four regions of Ethiopia. Observations of the HEWs' assessment and classification of sick children were followed by child re-examination by a trained health officer. RESULTS: The classification by the HEWs of 620 sick children as compared to the re-examiner had a sensitivity of 89% and specificity of 94% for diarrhoea, sensitivity 52% and specificity 91% for febrile disorders, and a sensitivity of 59% and specificity of 94% for acute respiratory tract infection. Malnutrition and ear infection had a sensitivity of 39 and 61%, and a specificity of 99 and 99%, respectively. CONCLUSION: Most cases of diarrhoea were correctly classified, while other illnesses were not frequently identified. The identification of malnutrition was especially at fault. These findings suggest that a significant number of sick children were undiagnosed that could lead to absent or incorrect management and treatment

Performance Evaluation of Small white Common Bean Genotypes in Eastern Amhara, Ethiopia

Common bean regional variety trial was carried out at Sirinka, Jari, Cheffa and West belesa (Gondar) from 2017 to 2019 cropping season. The objectives of the trial were to evaluate the performance of genotypes for grain yield and yield related traits and to select and promote the promising ones for verification. Fourteen genotypes including Awash-2 (standard check) were tested using RCBD. Analysis of variance and GGE biplot analysis was employed on multi-environment grain yield data. The combined analysis of variance showed significant differences for both main and interaction effects of genotypes, locations which led to exploit the significant effect of genotype-by-environment interaction. Based on the analysis of variance and GGE biplot analysis, two varieties namely DAB-413 and ZABR 16575-51 F-22 with average grain yield of 2729 kg/ha and 2501 kg/ha, respectively were selected, verified and DAB-413 and have been released for Sirinka, Jari, Cheffa and similar areas in Ethiopia. Therefore, DAB-413 has been recommended for the tested and other similar common bean growing areas to increase production and productivity of this crop.

Infection prevention and control practices in the Pediatrics and Child Health Department of Tikur Anbessa Specialized Hospital, Ethiopia

BackgroundInfection prevention and control (IPC) is a set of practices that are designed to minimize the risk of healthcare-associated infections (HAIs) spreading among patients, healthcare workers, and visitors. Implementation of IPC is essential for reducing infection incidences, preventing antibiotic use, and minimizing antimicrobial resistance (AMR). The aim of the study was to assess IPC practices and associated factors in Pediatrics and Child Health at Tikur Anbessa Specialized Hospital.MethodsIn this study, we used a cross-sectional study design with a simple random sampling method. We determined the sample size using a single population proportion formula with the assumption of a 55% good IPC practice, a 5% accepted margin of error, and a 15% non-response rate and adjusted with the correction formula. The final sample size was 284 healthcare workers. The binary logistic regression model was used for analysis. The World Health Organization (WHO) Infection Prevention and Control Assessment Framework (IPCAF) tool was used to assess IPC core components.ResultA total of 272 healthcare workers participated in the study, with a response rate of 96%. Of the total participants, 65.8% were female and 75.7% were nurses. The overall composite score showed that the prevalence of good IPC practices among healthcare workers was 50.4% (95% CI: 44.3–56.5). The final model revealed that nursing professionals and healthcare workers who received IPC training had AORs of 2.84 (95% CI: 1.34–6.05) and 2.48 (95% CI: 1.36–4.52), respectively. The final average total IPCAF score for the IPC level was 247.5 out of 800 points.ConclusionThe prevalence of good IPC practice was suboptimal. The study participants, who were nursing professionals and healthcare workers who received IPC training, showed a statistically significant association with the IPC practice level. The facility-level IPCAF result showed a “Basic” level of practice based on the WHO categorization. These evidences can inform healthcare workers and decision-makers to identify areas for improvement in IPC practice at all levels. Training of healthcare workers and effective implementation of the eight IPC core components should be strengthened to improve suboptimal practices

Rotavirus-associated acute diarrhea outbreak in West Shewa Zone of Oromia Regional State, Ethiopia, 2017

Introduction: rotavirus causes severe-diarrheal diseases in infants. An estimation of 138 million rotavirus-associated diarrheal cases and 215,000 deaths occur every year globally. In December 2016, West-Shewa zone in Ethiopia reported unidentified gastrointestinal diarrhea outbreak. We investigated to identify the causative agent of the outbreak to support response operations. Methods: medical records were reviewed, and the daily line list was collected from health facilities. Descriptive data analysis was done by time, person and place. Stool specimens were first tested by antigen capture enzyme immunoassay (EIA) technique and further confirmed by reverse-transcription polymerase chain reaction (RT-PCR) as a gold standard. The product of RT-PCR was genotyped for each gene using G1-G4, G8-G9 and G12 primers for VP7 gene and P(4), P(6), P(8) and P(14) primers for VP4 gene. Results: a total of 1,987 diarrheal cases (5.7 per 1000) and five deaths (case-fatality rate 0.25%) were identified and epidemiologically-linked to confirmed rotavirus from December 2016 to February 2017. Among the cases, 1,946 (98%) were < 5 children. Fourteen (74%) of the 19 tested stool specimens were positive for rotavirus by EIA and RT-PCR. Majority of strains detected were G12P(6) (25%) and G-negative P(8) (25%) followed by G9P(8) (19%), G1P(8) (13%) and G3/G2 P(8), G12P(8), and G-negative P(6) (6% each). Conclusion: diarrheal outbreak which occurred in West-Shewa zone of Ethiopia was associated with rotavirus and relatively more affected districts with low vaccination coverage. Routine rotavirus vaccination quality and coverage should be evaluated and the surveillance system needs to be strengthened to detect, prevent and control a similar outbreak

Genetic diversity in tef [Eragrostis tef (Zucc.) Trotter]

Tef [Eragrostis tef (Zucc.) Trotter] is a cereal crop resilient to adverse climatic and soil conditions, and possessing desirable storage properties. Although tef provides high quality food and grows under marginal conditions unsuitable for other cereals, it is considered to be an orphan crop because it has benefited little from genetic improvement. Hence, unlike other cereals such as maize and wheat, the productivity of tef is extremely low. In spite of the low productivity, tef is widely cultivated by over six million small-scale farmers in Ethiopia where it is annually grown on more than three million hectares of land, accounting for over 30% of the total cereal acreage. Tef, a tetraploid with 40 chromosomes (2n = 4x = 40), belongs to the family Poaceae and, together with finger millet (Eleusine coracana Gaerth.), to the subfamily Chloridoideae. It was originated and domesticated in Ethiopia. There are about 350 Eragrostis species of which E. tef is the only species cultivated for human consumption. At the present time, the gene bank in Ethiopia holds over five thousand tef accessions collected from geographical regions diverse in terms of climate and elevation. These germplasm accessions appear to have huge variability with regard to key agronomic and nutritional traits. In order to properly utilize the variability in developing new tef cultivars, various techniques have been implemented to catalog the extent and unravel the patterns of genetic diversity. In this review, we show some recent initiatives investigating the diversity of tef using genomics, transcriptomics and proteomics and discuss the prospect of these efforts in providing molecular resources that can aid modern tef breeding

Inter-connection between land use/land cover change and herders’/farmers’ livestock feed resource management strategies: a case study from three Ethiopian eco-environments

AbstractWe assessed land use/land cover changes from remotely sensed satellite imagery and compared this with community perceptions on availability/use of livestock feed resources and feed deficit management strategies since the 1973s in three districts representing the pastoral, agro-pastoral and mixed crop-livestock eco-environments of Ethiopia. We found that land use/land cover changes are proceeding in all eco-environments and that transitions are from grasslands, and forest lands to bush/shrub lands and crop lands in the pastoral site (Liben), from bush/shrub lands and grasslands to crop lands in agro-pastoral site (Mieso) and from bush/shrub lands, forest lands and grasslands to crop lands in the mixed crop-livestock site (Tiyo). The changes significantly affected livestock feed resources and feed deficit management strategies available to households. Over the last 30–40 years, grazing resources available to livestock keepers have been declining with resultant increase in the contribution of crop residues and other feeds from crop lands (weeds and crop thinnings) as compared to feeds from grasslands. The feed deficit management strategies of households are also changing significantly from mobility to herd management and feed conservation in the pastoral areas; from mobility to feed conservation and purchasing of feed in the agro-pastoral areas and from transhumance to feed conservation and purchase of feed in the mixed crop-livestock areas. Hence feed resources and their availability vary with time and eco-environments indicating the need for the development of eco-environment/site specific feed management strategies in order to support productive stock in the study areas and similar eco-environments
