Background: Basic life support (BLS) is a critical skill for saving lives during emergencies. This study aims to assess BLS awareness and knowledge among undergraduates at University, examining the impact of gender, faculty, prior correct cardiopulmonary resuscitation (CPR) training on students’ confidence competence. Methods: A descriptive, cross-sectional was conducted from August December 2023 across six faculties: medicine, nursing, engineering, sciences, commerce, law. Using convenience...
Eggshell penetration by pathogens is considered a potential route for their transmission in poultry flocks. Additionally, case of zoonotic pathogens, contact with infected eggs or consumption can result human infection. Chlamydia psittaci bacterium that causes respiratory disease and humans. In this study, we provide an experimental evidence eggshell C. psittaci. show after penetration, could eventually infect the growing embryo. Our findings portend horizontal trans-shell as possible spread...
In the present study, a bivalent vaccine against Pasteurella multocida and rabbit hemorrhagic disease virus (RHDV) was formulated with Montanide™ ISA70 oil adjuvant (Seppic, Paris, France). Its efficacy evaluated compared to similar monovalent preparations commercially available vaccines. White new Zeeland groups (n = 10) received 2 successive doses of tested vaccines were challenged weeks after 2nd dose RHDV or either pathogens according their vaccination schedule. Challenged not-vaccinated...
In the present study, reticuloendotheliosis (REV) provirus DNA was detected by PCR using LTR (long terminal repeat)-specific primers to amplify 200 bp fragment of REV viral genome in tumor samples collected from broiler breeder flocks with 30–40 weeks age demonstrating neoplastic lesions. Histopathology examination liver tissue showed reticular cells infiltration and proliferation replacing hepatic parenchyma. Sequence analysis amplified products revealed genetic similarity REV-LTR MDV...
Abstract Background Equine influenza is an important cause of respiratory disease in equids. The causative virus; EIV, highly variable and can evolve by accumulation mutations, particularly the haemagglutinin (HA) gene. Currently, H3N8 sole subtype circulating worldwide with Florida clade 1 (FC1) most prevalent Americas FC2 Asia Europe. In Egypt, EIV was detected two occasions: H7N7 1989 2008. No data available on circulation pattern during last decade despite frequent observation suspected...
Treatment of human and animals for protection from pathogens infection has significant economic value, especially with the harmful Salmonella arizonae. Beneficial cameloid heavy-chain antibodies as single-domain antigen-binding fragments known VHHs or nano-bodies may be acceptable option producing treatment and/or diagnostic agents. In current study, we developed a sandwich ELISA based nano-body towards S. arizonae first report using cDNA synthesized immunized camels RNA to isolate 700 bp...
The objective of the present study was to prepare a trivalent inactivated vaccine Newcastle disease virus (NDV), H5N1, and H9N2 viruses.Three monovalent vaccines were prepared by emulsifying NDV (LaSota strain), reassortant viruses with Montanide ISA 71 oil adjuvant. Parameters used for evaluation efficacy in specific pathogen-free chickens cellular immunity assays (blastogenesis, interferon gamma, interleukin 1 [IL1], IL6), humoral hemagglutination inhibition, protection percentage,...
Duck hepatitis virus (DHV) is one of the commercially important diseases ducklings worldwide. It an acute and highly infectious disease caused by three different serotypes (1–3) duck A (DHAV), serotype 1 most common in poultry. To date, little known about prevalence genetic characterisation DHAV-1 Egypt. In current study, isolation complete genomic analyses DHAVs circulating commercial farms Egyptian governorates were conducted. total eighteen samples collected from six 3–11 days old (Pekin...
Marine and brackish water aquacultures are rapidly expanding in the Mediterranean basin. In this context, Egypt recently received a shipment of 1.5 million juvenile gilthead seabream (Sparus aurata L.) from European facility. Within few weeks their arrival, 95% imported fish developed nodules on skin fins that lasted for several months. This study was undertaken to describe clinical disease course, identify causative agent, investigate its origin. Preliminary diagnosis based gross lesions...
Chlamydia suis infections lead to economic loss in the pork industry. could be successfully treated with tetracyclines until appearance of a tetracycline resistant phenotype, which was acquired via horizontal gene transfer tet(C) gene. Given importance C. as swine pathogen and recently emerged zoonotic potential, our aim develop sensitive suis-specific antibody ELISA based on polymorphic membrane proteins (Pmps). Pmps are important virulence factors candidate antigens for serodiagnosis. We...
Gallid alphaherpesvirus 2 (GaHV-2) is a highly contagious oncogenic virus that causes Marek's disease in chickens and occasionally turkeys. Among 100 genes identified GaHV-2 genome, the Meq gene appears to involve viral virulence, oncogenicity, genetic diversity. Despite use of sequences phylogenetic classification strains circulating many countries worldwide, no integrated system exists yet.Turkeys from commercial Egyptian farms were presented with signs dullness, dehydration, emaciation....
Background: Disorders of the thyroid gland, including toxic and non-toxic goitre, are more common in adult female patients. Hypoxia-inducible factors, HIF-1 HIF-2, represent transcriptional activators that function as regulators oxygen homeostasis. Rapid progress is being made clarifying homeostatic functions HIFs several physiological systems. However, there much to be learned connection with gland its pathologies.Aims Objectives: To assess biochemical clinical significance...
A pool of brain sample was collected from three pigeons showing torticollis and whitish green diarrhea in Desouk, Kafr-elshiekh Province, Egypt,during January, 2014. Virus Isolation has been pursued by inoculation homogenate into the allantoic sac 9 day old specific pathogen free (SPF) embryonated chicken eggs incubated at 37oC for 4 days. Identification isolate carried out haemagglutination inhibition test using polyclonal antisera against NDV AIV ( subtype H5 H9), RT-PCR confirmed...
IgM monoclonal gammopathies such as myeloma and Waldenström macroglobulinaemia are distinct haematological conditions; however, differentiating between these entities can often present a challenge. In this review, we explore the challenging diagnosis treatment of in patient presenting with unexplained macrocytic anaemia, elevated serum protein levels absence t(11;14) lytic bone lesions that classically associated myeloma. The was established based on 40% plasma cell population marrow biopsy,...
Background: Equine influenza (EI) is a transmissible viral respiratory sickness of the Equidae family. Two viruses, H7N7, and H3N8 caused EI, however, H7N7 has not been detected for decades. circulated bifurcated into Eurasian American lineages. The latter subsequently diversified Kentucky, South America, Florida sub-lineages. clade 1 (FC1) 2 (FC2) strains are only circulating equine viruses in meantime. Immunization considered major means prevention control EI infection. Using disparate...
In this study, a recombinant DNA plasmid was constructed, encoding for HA1 of selected Egyptian H5N1 virus (isolated during the 2012 outbreaks). immunization and challenge experiments, SPF chickens received 1 or 2 doses H5-DNA prime, boosted with inactivated H5N2 vaccine. Haemagglutination inhibition (HI) titers, protection levels, magnitude shedding were compared to that either vaccine alone. A/chicken/Egypt/128s/2012 (H5N1) highly pathogenic avian influenza (HPAI) clade 2.2.1/C used...
