Feline morbillivirus (FmoPV) is an emerging virus that was recently discovered in domestic cats with chronic nephritis. Despite the potential role of FmoPV in chronic nephritis, little is known about its biological characteristics. In this study, we established a quantitative assay of FmoPV by using an indirect immunofluorescence technique. Viral titers of FmoPV were determined in one week. Tre...
We examined 138 Escherichia coli strains isolated from cultures of blood specimens from urosepsis patients (n = 78) and nonurosepsis patients (n = 30) and from fecal specimens of a healthy control group (n = 30) for P fimbriation with a mannose-resistant hemagglutination test, an indirect immunofluorescence assay, and a new commercial particle agglutination test (PF TEST; Orion Diagnostica, Esp...
The indirect fluorescent antibody technique has been used to titrate patients' antibody against Toxoplasma gondii. Rigorous tests of the immunological validity of the method were made. The reactions of the gamma globulin of human immune serum with Toxoplasma gondii and fluorescent rabbit anti-human gamma globulin were thus shown to be specific. Thereafter the technique could be used with confid...
The consumption of bottled mineral water has significantly increased in Brazil so that it is in the interest of public health to determine the parasitological and microbiological status of some brands of Brazilian mineral water available in the town of Campinas, São Paulo, Brazil. For this purpose, detection of protozoa by direct immunofluorescence technique and microbiological parameters were ...
Two hundred and thirty children clinically diagnosed as suffering from acute respiratory infection were tested for four major groups of viral aetiological agents, i.e. influenza para-influenza, respiratory syncytial virus (RSV) and adenoviruses using indirect immunofluorescence technique. At least one of the respiratory viruses was identified in 51 (22 per cent) specimens, which included influe...
Canine rabies is endemic in Nigeria. Some of the dogs slaughtered for human consumption may be infected with rabies virus, thus exposing handlers of raw dog meat to the disease since the virus may be present in the nerves in the meat. A cross-sectional study was designed and a structured questionnaire was designed and administered to a convenience sample of 160 processors and consumers (100 fro...
Abstract Background: Rabies is the most important zoonosis in country. Anti-viral antibody conjugated with Fluorescein Isothiocyanate (FITC), is used for diagnosis of Rabies. We import this reagent from abroad. In this study we aimed to prepare this conjugated fluorescein antibody and assess its utility. Materials and methods: Rabbits were immunized with rabies vaccine, then serum samples ...
