Participatory Barley Variety Selection and Farmers’ Selection Criteria in the Bale Highlands of Southeastern Ethiopia

The aim of the study was to identify farmers’ selection criteria, preferences and generate baseline information on the importance of participatory  barley breeding in Southeastern part of Ethiopia. The experiment was  conducted in non-replicated plots at each location on plot size of 16m2 in 2007 Bona and on 25m2 in 2008 Ganna and Bona cropping seasons. Yield data was taken in kg plot-1 and converted in to t ha-1 .Selection criteria was set together with farmers; and ranked by farmers and breeders. Farmers and breeders made visual score of each plot on 1-5 scale beside variety selection. Some farmers were supported by the staff in case of datarecording problem. The result showed that grain yield, disease resistance, effective tillers, early maturity and kernel size (plumpness) were among the most important selection criteria commonly used farmers. While, breeders preferred high yielding variety with insect and disease resistant and early maturing types. And farmers were able to identify the higher yielding barley varieties as breeders. Varieties such as Guta, Dinsho, Biftu and Abdane were selected as the best varieties preferred by most of the local farmers across locations except at Hora Soba (Upper Dinsho) site. Shage, Dimtu varieties and 27th IBON 73/99 (semi-dwarf advanced line) were preferred by the Hora Soba local farmers. Thus, attention should be given to seed multiplication and dissemination of barley varieties which have been highly preferred by the local farmers. It is important to consider farmers preferences in crop improvement to improve the adoption of  agricultural technologies which ultimately have significant contribution in production and productivity

Seroprevalence of Salmonella Gallinarum Infection in Chicken Population of parts of Tigray and Addis Ababa by Plate Agglutination and Micro-agglutination Tests

Ethiopia owns a large poultry population whose growth is highly constrained by diseases. Fowl typhoid is a serious concern in growing and adult poultry and results from infection by Salmonella Gallinarum (Salmonella enterica subsp. enterica serovar Gallinarum biovar Gallinarum). Knowledge of the prevalence of the disease with confirmatory diagnosis is of paramount importance to embark on a control or prevention program. Seroprevalence of this infection in chicken population of Ethiopia has been reported from some parts of this country but in most of the reports it is based exclusively on a rapid slide agglutination test without further confirmation by another specific test. This study screened 279 sera samples of poultry for S. Gallinarum infection by employing plate agglutination test using colored antigen of S. Gallinarum that revealed 125(44.80%) of 279 sera samples positive. However, when plate positive samples were further tested for confirmation by microagglutination test by employing plain antigen of S. Gallinarum, only 55 (19.71%) were serologically positive lowering the prevalence rate from 44.8% to 19, 71%. The study reveals the serological prevalence of Salmonella gallinarum infection in poultry population of the study areas and recommends that the initial screening of this infection by a test like plate agglutination must always be followed by another specific test to get an accurate estimate of this infection.Keywords: Micro-agglutination test, Plate agglutination test, Poultry population, Salmonella gallinarum, Seroprevalence, Addis Ababa, Tigray, Ethiopia

Assessment of barriers to the implementation of community-based data verification and immunization data discrepancies between health facilities and the community in Tach Gayint district, Northwest Ethiopia.

AbstractIntroduction: While community-based data verification (CBDV) is critical for effective implementation of immunization programs, limited evidence exists detailing its implementation at the local levels thereby threatening data quality which is used to guide decision making.Aim: To explore the barriers to proper implementation of CBDV and determine the level of immunization data discrepancy between the health facilities and community levels in Tach Gayint district of Northwest Ethiopia.Methods: A Mixed methods approach was used. Interviews with twenty-six key informants’ (health experts) in immunization data, and an additional a sample of 324 infants were recruited. All health centers in the district (6) and 2 health posts from each health center (12 in total) were selected using Simple Random Sampling. Key informant interviewees were purposely included from all health facilities. For quantitative data, samples of infants were proportionally allocated for each health facility as per their DPT/Pentavalent-1 vaccine report. Thematic analysis of the qualitative data and descriptive quantitative analysis were performed using statistical software open-code v-4.02 and STATA v14.1 respectively.Results: Only few health facilities implemented CBDV and consider it to be their routine task. Also, barriers to effective implementation of CBDV such as lack of prioritization, poor capacity among health staff, and conflicting job roles were identified. The highest immunization data discrepancy among community and health facilities was observed for the measles-one vaccine (35.4%), and the minimum was for DPT/Pentavalent-1 (25.6%).Conclusion: This study revealed a poor level of CBDV implementation and barriers to its effective implementation which include lack of prioritizing CBDV, limited capacity among health staff in performing CBDV, and conflicting job roles among health staff. There was a high level of immunization data discrepancy for measles-1 and DTP/Pentalent-3 vaccines. Based on our finding, we make the following recommendations: building skills among health workers to perform CBDV, enhancing availability and use of standard CBDV tools, ensuring monitoring, and control mechanism, and setting clear definition of roles regarding CBDV, as well as closing the gap in level of immunization data discrepancy could help foster effective implementation of CBDV.

Worldwide distribution and environmental origin of the Adelaide imipenemase (AIM-1), a potent carbapenemase in Pseudomonas aeruginosa

Published 17 December 2021Carbapenems are potent broad-spectrum β-lactam antibiotics reserved for the treatment of serious infections caused by multidrug-resistant bacteria such as Pseudomonas aeruginosa. The surge in P. aeruginosa resistant to carbapenems is an urgent threat, as very few treatment options remain. Resistance to carbapenems is predominantly due to the presence of carbapenemase enzymes. The assessment of 147 P. aeruginosa isolates revealed that 32 isolates were carbapenem non-wild-type. These isolates were screened for carbapenem resistance genes using PCR. One isolate from wastewater contained the Adelaide imipenemase gene (bla AIM-1) and was compared phenotypically with a highly carbapenem-resistant clinical isolate containing the bla AIM-1 gene. A further investigation of wastewater samples from various local healthcare and non-healthcare sources as well as river water, using probe-based qPCR, revealed the presence of the bla AIM-1 gene in all the samples analysed. The widespread occurrence of bla AIM-1 throughout Adelaide hinted at the possibility of more generally extensive spread of this gene than originally thought. A blast search revealed the presence of the bla AIM-1 gene in Asia, North America and Europe. To elucidate the identity of the organism(s) carrying the bla AIM-1 gene, shotgun metagenomic sequencing was conducted on three wastewater samples from different locations. Comparison of these nucleotide sequences with a whole-genome sequence of a P. aeruginosa isolate revealed that, unlike the genetic environment and arrangement in P. aeruginosa, the bla AIM-1 gene was not carried as part of any mobile genetic elements. A phylogenetic tree constructed with the deduced amino acid sequences of AIM-1 suggested that the potential origin of the bla AIM-1 gene in P. aeruginosa might be the non-pathogenic environmental organism, Pseudoxanthomonas mexicana.Anteneh Amsalu, Sylvia A.

© 2015 Tran et al. This is an open access article distributed under the terms of the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original author and source are credited. Introduction. Institutions play a central role in advancing the field of reproductive health in humanitarian settings (RHHS), yet little is known about organizational capacity to deliver RHHS and how this has developed over the past decade. This study aimed to document the current institutional experiences and capacities related to RHHS. Materials and Methods. Descriptive study using an online questionnaire tool. Results. Respondents represented 82 institutions from 48 countries, of which two-thirds originated from low-and middle-income countries. RHHS work was found not to be restricted to humanitarian agencies (25%), but was also embraced by development organizations (25%) and institutions with dual humanitarian and development mandates (50%). Agencies reported working with refugees (81%), internally-displaced (87%) and stateless persons (20%), in camp-based settings (78%), and in urban (83%) and rural settings (78%). Sixtyeight percent of represented institutions indicated having an RHHS-related policy, 79% an accountability mechanism including humanitarian work, and 90% formal partnerships with other institutions. Seventy-three percent reported routinely appointing RH focal points to ensure coordination of RHHS implementation. There was reported progress in RHHSrelated disaster risk reduction (DRR), emergency management and coordination, delivery of the Minimum Initial Services Package (MISP) for RH, comprehensive RH services in post-crisis/recovery situations, gender mainstreaming, and community-based programming. Other reported institutional areas of work included capacity development, program delivery, advocacy/policy work, followed by research and donor activities. Except for abortion-related services, respondents cited improved efforts in advocacy, capacity development and technical support in their institutions for RHHS to address clinical services, including maternal and newborn health, sexual violence prevention and response, HIV prevention, management of sexually-transmitted infections, adolescent RH, and family planning. Approximately half of participants reported that their institutions had experienced an increase in dedicated budget and staff for RHHS, a fifth no change, and 1 in 10 a decrease. The Interagency RH Kits were reportedly the most commonly used supplies to support RHHS implementation. Conclusion. The results suggest overall growth in institutional capacity in RHHS over the past decade, indicating that the field has matured and expanded from crisis response to include RHHS into DRR and other elements of the emergency management cycle. It is critical to consolidate the progress to date, address gaps, and sustain momentum

Sub-national prevalence survey of tuberculosis in rural communities of Ethiopia

Abstract Background Tuberculosis is a major public health problem with varying prevalence in different settings. National prevalence surveys provide evidence for planning and decision making. However, they lack the capacity to estimate subnational magnitude that affected the capacity to make selected intervention based on the prevalence. Ethiopia is among high TB burden countries with estimated prevalence of 108 per 100,000 population varying by regions. We aimed to study sub national prevalence of smear-positive TB in rural communities of southern Ethiopia. Methods This cross-sectional study, enrolled community members aged over 14 years who had cough of at least two weeks duration. Two sputum samples were collected and examined by using smear microscopy. Results 38,304 eligible people were enumerated (10,779 from Hadiya, 10,059 from Gurage and 17,466 from Sidama) and indentified 960 presumptive cases. 16, 14 and 14 smear-positive pulmonary TB cases were identified respectively. The point prevalence of smear-positive TB were 148 per 100,000 population (95% CI: 91–241) in Hadiya, 139 per 100,000 population (95% CI: 83–234) in Gurage and 80/100,000 population (95%CI: 48–135) in Sidama zone. Gurage zone had the highest prevalent to notified cases of seven to one. Conclusions The prevalence of smear positive TB varies by districts and is high in rural southern Ethiopia compared to the estimated national prevalence. More TB patients remain missed and unreached, impacting negatively on health outcomes. TB case finding approaches should be revisited and innovative approaches and tools to identify missing people with TB should be scaled up

Childhood and adult tuberculosis in a rural hospital in Southeast Ethiopia: a ten-year retrospective study

<p>Abstract</p> <p>Background</p> <p>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 during TB treatment in a rural hospital over a 10-year period (1998 to 2007).</p> <p>Methods</p> <p>Retrospective data collection using TB registers and treatment cards in a rural private mission hospital. Information was collected on number of cases, type of TB and treatment outcomes using standardised definitions.</p> <p>Results</p> <p>2225 patients were registered, 46.3% of whom were children. A total of 646 patients had smear-positive pulmonary TB (PTB), [132 (20.4%) children]; 816 had smear-negative PTB [556 (68.2%) children], and 763 extra-PTB (EPTB) [341 (44.8%) children]. The percentage of treatment defaulters was higher in paediatric (13.9%) than in adult patients (9.3%) (p = 0.001). The default rate declined from 16.8% to 3.5%, and was independently positively associated with TB meningitis (AOR: 2.8; 95% CI: 1.2-6.6) and negatively associated with smear-positive PTB (AOR: 0.6; 95% CI: 0.4-0.8). The mortality rate was 5.3% and the greatest mortality was associated with adult TB (AOR: 1.7; 95% CI: 1.1-2.5), TB meningitis (AOR: 3.6; 95% CI:1.2-10.9), and HIV infection (AOR: 4.3; 95% CI: 1.9-9.4). Decreased mortality was associated with TB lymphadenitis (AOR: 0.24; 95% CI: 0.11-0.57).</p> <p>Conclusion</p> <p>(1) The registration of TB cases can be useful to understand the epidemiology of TB in local health facilities. (2) The defaulter and mortality rate of childhood TB is different to that of adult TB. (3) The rate of defaulting from treatment has declined over time.</p
