In response to the outbreak of COVID-19, caused by the SARS-CoV-2 virus, several tests are needed for diagnosis of acute illness, contact tracking, diagnosis of asymptomatic infections, and assessment of herd immunity. While PCR is the standard test in acute type, serological tests have been developed and used to meet diagnostic needs due to the widespread prevalence of the disease. Unlike the...
Received: Revised: Accepted: November 16, 2013 May 11, 2014 May 30, 2014 The canine is regarded as a reservoir host for human visceral leishmaniasis in the Mediterranean regions. Ten golden jackals were captured from villages that belong to Basrah province, south of Iraq. The animals were inoculated experimentally with human case Leishmania donovani promastigotes, and then the jackals were diag...
BACKGROUND Novel serological methods provide alternative options for sero-diagnosis, sero-epidemiology and for determining evidence of naturally acquired or vaccine induced immunity. Micro-neutralization tests are currently the gold standard for serological studies of highly pathogenic avian influenza in mammalian species but require handling live virus in a biosafety level (BSL) 3 environment....
Toxoplasma gondii is a parasitic protozoan which is the cause of toxoplasmosis. Although human toxoplasmosis in healthy adults is usually asymptomatic, serious disease can occur in the case of congenital infections and immunocompromised individuals. Furthermore, despite the exact recognition of its etiology, it still presents a diagnostic problem. Diagnosis of toxoplasmosis is mainly based on t...
Objectives: The demonstration of the serological test importance in the diagnosis of the Congenital Toxoplasmosis. The Method: The serological test was performed through the micro enzymatic immunology technique, on a lot of 87, new born suckling babies. Along with the laboratory investigations the babies were also clinical, oftalmological and neuron-imagistic examined. Results: The diagnosis of...
Serological diagnosis provides a robust and effective approach to monitoring controlling small ruminant brucellosis. Brucella melitensis Rev. 1 is live vaccine strain used in prophylactic vaccination against Because the shares identical serological antigens with corresponding field strains, differentiating infected from vaccinated animals (DIVA) responses hamper surveillance campaigns intervent...
The aim of the study was to determine usefulness FCoV Ab rapid serological tests in diagnosis effusive form FIP cats. cats included were divided into two groups. group consisted 40 with a strain causing (the presence M1058L mutation) abdominal fluid determined using PCR. control 15 ascites caused by factors other than infection. Serological examination demonstrated antibodies feline coronavirus...
Brucella canis is the causative agent of canine brucellosis and facultative intracellular pathogen. The diagnosis of canine brucellosis is based on bacteriological examination and serological methods including agglutination and gel diffusion tests. In this study, crude antigens were extracted from B. canis using hot saline, coated on to latex beads and their usefulness in the serological diagno...
The diagnosis of congenital syphilis is difficult since it depends mainly on the results of serological tests. The results of five serological tests (three specific and two non-specific) in nine neonates with congenital syphilis are compared with those obtained in three with passively acquired antibodies. It appeared that the serological diagnosis of congenital syphilis must be based on the fin...
Mouse hepatitis virus (MHV) infection is found commonly in laboratory mice and this virus has been known to cause various diseases such as subclinical infection, enteritis, hepatitis, and encephalitis. Serological tests are used commonly to diagnose MHV infection. Complete MHV virions have been used primarily as antigens for serological diagnosis to date. To develop an antigen that is more spec...
