to determine the seroprevalence of anti-neospora caninum and anti-toxoplasma gondii antibodies indogs in iran and to investigate related risk factors to the infection, a study was conducted in chaharmahal vabakhtiari, isfahan and khoozestan provinces, locate in west central parts of iran. for this, 548 serum samples were collected from dogs during an 18 month period from july 2007 to february 2...

an indirect enzyme–linked immunosorbent assay (elisa) was developed for screening of antibody to avian infectious bronchitis virus (ibv). antigen was prepared from whole-purified ibv massachusetts serotype (br 801 strain). optimum dilution with minimum background for antigen concentration, rabbit anti-chicken conjugate and sera in developed elisa was determined 0.1μg/ml, 1:3000 and 1:100, respe...

Foot and mouth disease (FMD) is a contagious animal disease that causes irreparable damage to the economy of countries, including Iran in which this disease is a native one. Among the ways to combat FMD are vaccination and slaughter. Due to the specific situation of Iran, it is not possible to kill infected animals. Therefore, vaccination is the most important way to fight this disease. S...

The nucleocapsid (N) gene of infectious bronchitis virus (IBV) strain X isolated in China was expressed in E. coli and was purified as a recombinant protein. An indirect ELISA assay (N-ELISA) for antibody detection was established using the purified recombinant nucleocapsid protein. Antigen coating conditions and serum dilution for the N-ELISA were optimized. The S/P ratio of the absorbency val...

BACKGROUND Early diagnosis of tuberculous meningitis (TBM) is still a challenge; the present study aimed to establish a method of detecting the antigen early secreted antigenic target 6 (ESAT-6) in cerebrospinal fluid (CSF) by an indirect enzyme-linked immunosorbance assay (ELISA) protocol and to study the value of detecting ESAT-6 in CSF in the early diagnosis of TBM. METHODS An indirect ELI...

An indirect enzyme linked immunosorbent assay (ELISA) was developed for the diagnosis of allergy to a house dust mite, Dermatophagoides farinae. The efficacy of the ELISA was then evaluated against a prick test using a commercial allergen. Eighty five suspected allergic rhinitis patients from the Otorhinolaryngology Department, Kuala Lumpur General Hospital, were tested with the ELISA and prick...

IMPORTANCE A rare variant of mucous membrane pemphigoid (MMP) is characterized by circulating anti-laminin 332 (Lam332) autoantibodies and seems to be associated with concurrent malignant neoplasms. OBJECTIVE To determine the prevalence and clinical significance of anti-Lam332 autoantibody detection from a large series of patients with MMP. DESIGN Multicenter retrospective study. SETTING ...

Polyclonal antibodies of predetermined specificity for pediocin PA-1 (pedA1) have been generated by immunization of rabbits with a chemically synthesized C-terminal fragment of this bacteriocin (PH2) conjugated to the carrier protein keyhole limpet hemocyanin (KLH). The sensitivity and specificity of the PH2-KLH-generated antibodies were evaluated by the development of various enzyme-linked imm...
