Introduction: Pathogenic strains cause diarrheal infection in children due to their virulence factors. A nonanalytical observational study followed by a purposive sampling technique was conducted from October 2017 to June 2018, to determine the antimicrobial susceptibility patterns and molecularly detect pathogenic strains in under-five children at Wolaita Sodo town using molecular and the Kirby-Bauer disc diffusion method.

Result: In the current investigation, out of 110 stool samples, was isolated in 68 (61.

Article Synopsis
  • Leptospirosis is a widespread spirochaetal infection that affects a variety of mammals, and this study compares diagnostic methods for detecting it in humans.
  • The research evaluates the microscopic agglutination test (MAT) against two point-of-care tests: the IgM dot ELISA dipstick test (IgM-DED) and the latex agglutination test (LAT), using Bayesian latent class modeling to analyze their effectiveness.
  • Results show that the IgM-DED and LAT provide high sensitivity for early detection of leptospirosis, outperforming the single MAT test, and suggest that these point-of-care tests are practical for use in remote areas, while combining acute and convalescent samples significantly boosts MAT sensitivity.

Introduction: are among the major causes of mortality and morbidity in under-five children in developing nations including Ethiopia.

Methods: A non-analytical observational study design followed by a purposive sampling technique was conducted from October 2017 to June 2018, to isolate and determine its associated risk factors from diarrheic children that were admitted to Christian hospital, Wolaita Sodo town. was confirmed using standard culture and biochemical analyses of the bacterium.

A cross-sectional study was conducted on selected dairy farms in and around Jimma town, Oromia, southwestern Ethiopia from November 2019 to May 2020 to determine the seroprevalence of (). Furthermore, information was gathered on individual animal and herd level by using pretested semistructured questionnaire to assess associated risk factors. A stratified and simple random sampling procedure was used for the selection of dairy farms and individual animal's, respectively.

Leptospirosis is responsible for hampering the productivity of swine husbandry worldwide. The aim of this study was to assess the efficacy of bioinformatics tools in predicting the three-dimensional structure and immunogenicity of recombinant LigBCon1-5 (rLigBCon1-5) antigen. A battery of bioinformatics tools such as I-TASSER, ProSA and SAVES v6.

Leptospirosis is an exacerbating factor responsible for the drastic decline of sloth bear population in India. In this study, a multipronged approach based on antigen detection using Polymerase Chain Reaction (PCR) employing G1/G2 and LigBF/LigBR primers, antibody detection using Microscopic Agglutination Test (MAT) and recombinant LigBCon1-5 antigen based Latex Agglutination Test (rLigBCon1-5 LAT), serum biochemistry using hepatic (serum glutamate oxalo acetic transaminase (SGOT) and serum glutamate pyruvic transaminase (SGPT) and renal biomarkers (blood urea nitrogen (BUN) and Creatinine) and gross/histopathological evidence in liver and kidneys were employed to investigate leptospirosis in captive sloth bears. A total of 133 serum samples collected from Agra (n=113) and Bannerghatta (n=20) sloth bear rescue centers were screened using MAT and rLigBCon1-5 LAT.

Poultry production plays a relevant role in the Ethiopian economy and represents a source of poverty alleviation for several social classes. Infectious diseases can therefore significantly impact the economy and welfare. Despite infectious bronchitis virus (IBV) and avian metapneumovirus (aMPV) being present, the knowledge of their epidemiology and impact is extremely limited.

Contagious bovine pleuropneumonia (CBPP) is a highly contagious disease of cattle which is one of the great plagues which continues to devastate the cattle herds on which so many people are dependent in Africa. Cross-sectional study was conducted from October 2015 to August 2016 to determine the seroprevalence of CBPP in cattle and associated risk factors in Gimbo district, Southwest Ethiopia. A total of 384 serum samples were collected and tested for the presence of specific antibodies against Mycoplasma mycoides subspecies mycoides small colony (MmmSC), using a competitive enzyme-linked immunosorbent assay (cELISA).

Objective: The status of bluetongue disease, vectors for transmission of the disease and the serotypes involved are not clearly known in Ethiopia. This sero-epidemiological study was conducted to determine the seroprevalence and associated risk factors of bluetongue in small ruminants of South Western Ethiopia.

Result: 422 serum samples were screened for the presence of bluetongue virus (BTV) specific antibodies using competitive enzyme-linked immunosorbent assay (c-ELISA) and 30.

Leptospirosis is a zoonotic disease caused by pathogenic spirochetes of the genus Leptospira, causing febrile infection characterized by multi-organ failure in humans and animals. Leptospiral Ig-like protein B (LigB) is a surface-expressed antigen that mediates host cell invasion or attachment. In this study, N-terminal conserved region of LigB protein (46 kDa) was evaluated for its diagnostic potential to detect anti-leptospiral antibodies in the sera of various animal species.

Article Synopsis
  • A survey of 124 chickens in Eastern Shewa zone, Ethiopia, revealed that 89.5% were infected with gastrointestinal helminths, primarily cestodes and nematodes.
  • The most common cestode species included Raillietina echinobothrida and Raillietina tetragona, while the major nematodes were Heterakis gallinarum and Ascaridia galli.
  • The study highlighted the severity of helminth infections in backyard chickens, urging the need for effective control measures, with significant differences in infection rates found between the two districts studied.
