The aim of the research was to conduct an in-depth analysis investigation chlamydial infections occurred in cats and dogs Kyiv during last 10 years. article includes three main directions investigation: 1) epizootic situation with chlamydiosis; 2) Microbiological 3) Serological monitoring. clinical epizootiological studies chlamydiosis have been looked into, focus on differences similarities ag...

The novel coronavirus, severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) has introduced as causative agent for coronavirus disease 2019 (COVID-19) since the 2019 December. Human coronaviruses are classified in Nidovirales order and Coronavirdiae family. This family includes four genera. The SARS-CoV-2 is a member of Betacoronavirus genera and Sarbecovirus linage (linage B). There is ...

Serological differentiation indices (SDIs) based on serum titrations in agar-gel double diffusion tests were determined for all ten definitive tombusviruses known at presen t, namely artichoke mottled crinkle, carnation Italian ringspot, cymbidium ringspot, eggplant mottled crinkle, Moroccan pepper, pelargonium leaf curl, petunia asteroid mosaic, the BS3 and type strains of tomato bushy stunt, ...

as the full test. It is performed as follows The apparatus.? (i) Small wooden racks about 12^ inclies by about 1^ inches (at the bottom) by 1^ inches, to hold 18 miniature test tubes, the bottom shelf painted black and the rest white, and the top numbered for the tubes. Each rack is also numbered, (w)' Durham's fermentation tubes measuring about 5 cm. by 8 mm. with internal diameter of 6 mm.A f...

Many of the nontreponemal or serological tests for syphilis involve the detection of serum antibodies (reagin) which are not directed against a component of the causative organism itself but may arise as a result of pathological changes brought about by proliferation of Treponema pallidum in host tissue. Test antigens for the detection of reagin are lipoidal, the main active component being the...

In a pilot study by field-screening in two different sauna baths, a day-sauna and a night-sauna, 318 homosexual men were investigated for syphilis and hepatitis B surface antigen (HBsAg) and its antibody (anti-HBs). Of the 134 visitors to the day-sauna 35 1-o were seroreactive for syphilis, four (3%) carried HBsAg, and 95 (70' 9%) anti-HBs. Of the 184 visitors to the night-sauna 33' 2% were ser...

CONTEXT The most frequently used methods for detecting antibodies are the indirect immunofluorescence test and the enzymatic immunoassay (ELISA). The polymerase chain reaction is a molecular biology technique in which the production of large amounts of specific DNA fragments is induced from very low concentrations of complex substrates aloowing the detection of very low amounts of viral particl...

Serological tests offer a potentially powerful tool for monitoring parasites in wildlife populations. However, such tests must be validated before using them with target wildlife populations. We evaluated in coyotes (Canis latrans) the performance of a commercially available serological test used to detect canine heartworm (Dirofilaria immitis) in domestic dogs. We obtained 265 coyote carcasses...
