This study was proposed to assess the distribution and importance of citrus leaf and fruit spot disease in North Western Ethiopia. The result showed that on sweet orange the prevalence of the disease was ranged from (0 to 100 %). Disease incidence was ranged from (0 to 86.48 %), and from (0 to100 %) on leaves and fruits, respectively. Disease severity was ranged from (0 to 24.18%) on leaves, and from (0 to 73.0 %) on fruits. Correlation analysis was carried out for both disease incidence and severity as response variables and altitude, average daily temperature, mean annual rainfall and tree age as predictor variables. Linear correlation was detected only between mean annual rainfall and disease severity and incidence of leaves and fruits. The regression analysis result indicated that mean annual rain fall has a significant effect over disease severity and incidence of leaves and fruits at (P ≤ 0.05).

Introduction: Morphologically abnormal blood cells in peripheral blood of a person reflect underlying pathological condition affecting formation, function, and lifespan of these cells. A properly identified morphological defect in peripheral blood cells is important to manage anemia, leukemia and other disorders of blood. This study aimed to assess magnitude and severity of morphological abnormality in blood cells of patients with abnormal complete blood count in public hospitals found in southern Ethiopia. Method: A facility-based cross-sectional study was conducted from January 01 to March 31, 2019 among five public hospitals in Southern Ethiopia. Peripheral blood sample and socio-demographic data were collected from 423 patients with abnormal complete blood count. Thin blood smear was prepared by Wedge method, stained with Wright’s Stain, and examined under microscope by 1000X magnification to detect and characterize abnormality in blood cells’ morphology. Descriptive statistical analysis was done using Statistical Package for Social Sciences version 20.0, and results are presented in tables and figures. Result: Prevalence of blood cell morphological abnormality was 63.8%. From this, 21.8% is marked and 78.2% is moderate abnormality. In 41.9% of the affected patients, the defect involved at least two blood cell types mainly affecting red blood cells. Females (73.8%), children (70.1%) and elderly (82.1%) carried higher prevalence of the abnormality. Conclusion: High prevalence of abnormality in PBS morphology was observed, chiefly among female, children and elderly. Stakeholders should work to alleviate the high prevalence, with particular attention to women, children and old-age people.

Background:The extensive use of antiretroviral therapy has favored the emergence of multiple patterns of drug resistance mutations. These mutations evolve over time and are only detected by the conventional Sanger sequencing technology when they exceed 20% at which time there may be cross resistance. Unfortunately, the controversy surrounding the significance of these minority drug resistance mutations is still overwhelming. Methods: Samples were obtained from patients who were failing on an NRTI based regimen between 2010 and 2019. For the subtype A and D analysis, 1000 patient samples were analyzed while the subtype C sub-analysis was comprised of 363 samples. Sanger based sequencing was performed as part of the standard of care. A subset of these samples was further analyzed using the Next Generation Sequencing (NGS) technology and analysis of the drug resistance mutations was performed at the 20% and 1% cut off to determine the prevalence of minority multi-drug resistant variants. Results: Although Thymidine analog mutations (TAMs) were prevalent in all subtypes, our analyses showed that these mutations occurred in significantly less proportions among subtype C infections when compared with the subtype A and D counterparts. On the other hand, the Q151M mutation complex was significantly more predominant among patients harboring subtype C variants. Analysis using NGS revealed that minority drug resistant mutations that confer multi-drug resistance (MDR) were present even in patients who exhibited a susceptible genotype based on the Sanger sequencing technique. Conclusion: Although HIV-1 MDR variants occur in all subtypes, their predominance is subtype specific with TAMs being significantly more predominant among subtype A and D while the Q151M complex more predominant among patients harboring subtype C viruses. Even in patients with a fully susceptible genotype based on Sanger technology, minority variants are present and their evolution to full blown MDR occurs over time such that if their early detection is missed, cross resistance is inevitable.

African region is thought to contribute to >50% of deadly cases of pertussis worldwide, however surveillance and available data on Bordetella pertussis circulation are limited. Currently, pertussis vaccination schedule in most African countries is restricted to a primary immunization consisting of three doses during the first year of life using whole pertussis vaccines for which effectiveness is not known.

To explore the disorders in the hematological index among normotensive, prehypertensive and hypertensive patients and help detect the predictive and preventive factors of hypertension-related complications. A comparative cross-sectional study was conducted from January to December 2018 on a total of 3000 study participants classified as hypertensive (HTN, blood pressure ≥140/90 mmHg), prehypertensive (PHTN, blood pressure =120-139/80-89 mmHg), and normotensive (NTN, blood pressure <120/80 mmHg) with 1000 participants in each group. Cross tabulation and Chi-square tests were used for categorical variables. The Kruskal-Wallis and Mann-Whitney U-test were used to compare the difference between groups.

The rise in cesarean delivery has higher maternal risks for the current and subsequent pregnancies. It is associated with short and long term complication as any surgical procedure. As prevalence of Cesarean section increased beyond reminded range without concomitant decrease in maternal and neonatal mortality and morbidity rates significant concern that C/S is over used once women has had one birth by Ceserean section.

Different tick species and tick-borne diseases of cattle are present in Ethiopia and they induce huge production loss in livestock industry by creating serious animal health problems. The present study was conducted from November 2017 to April 2018 in Arsi Negele and Asasa districts of West Arsi Zone, Oromia National Regional State, Ethiopia. A cross sectional study design and purposive sampling technique were employed to select 384 study animals so as to identify ticks species and tick-haemoparasite species and also to identify risk factors that affect the prevalence and association of tick born diseases. Tick and haemoparasite identification were carried out by using drect stereomicroscopic and direct thin blood examination. The study identified two tick genera and four tick species. The tick species encountered were Rhipicephalus decoloratus (51.6%) Ambylomma variegatum (46.1%) Ambylomma gemma (20.1%) and Rhipicephalus evertsi evertsi (1.2%). Out of all 384 cattle examined for the presence of tick-born haemoparasites 11.4% (n=44) of them were positive. From this 6.2%, 3.6 %, 1.3% and 0.8% of them were positive for Anaplasma marginale, Babesia bigemina, Babesia bovis and Anaplasma marginale, respectively. Two cattle (0.5%) were found positive for both Anaplasma marginale and Babesia bigemina. The highest prevalence of total tick born haemoparasites (57.1%) was occurred in A. Variegatum, A. gemma and R. decoloratus mixed infestations. In conclusion ticks and tick born haemoparasitic infections were common problems in the study area. Thus, awareness creation for farmers about the impacts of ticks and tick born diseases on livestock production and productivity and also applying appropriate and timely strategic tick control methods by veterinary service providers were advisable.
