The clinical diagnosis of Q fever is difficult. Whole cell antigens are currently used in several serological methods, but antigens are limited due to the hazardous nature of Coxiella burnetii cultivation. In this report, we described the method of detecting immunodominant antigens of C. burnetii by using proteomic techniques with patient sera, and cloning and expressing the selected antigens u...

An indirect enzyme-linked immunosorbent assay has been developed to identify strains of Rhizobium in culture and in lentil nodules. The test can be used on cells from both fresh and frozen nodules obtained from plants grown either in a growth chamber or in the field. Test results were confirmed by immunofluorescence. The enzyme-linked immunosorbent assay technique can be used for field studies ...

Single and double gel-diffusion techniques were employed to examine serologically coagulase-positive staphylococci from cheese for enterotoxigenicity. Supernatant fluid from sac cultures was examined for enterotoxins A and B. The results indicated that 9 of 155 cultures from market cheese and 7 of 77 cultures from food-poisoning cheese produced enterotoxin A, and that none of the cultures produ...

Accurate diagnosis of canine leishmaniasis (CanL) is essential toward a more efficient control of this zoonosis, but it remains problematic due to the high incidence of asymptomatic infections. In this study, we present data on the development of enzyme-linked immunosorbent assay (ELISA)-based techniques for the detection of antibodies against the recombinant protein Leishmania infantum cytosol...

BACKGROUND The biological diagnosis of toxoplasmosis after allogeneic hematopoietic stem cell transplantation (HSCT) is based on the detection of Toxoplasma gondii DNA in blood specimens or other samples. Serological testing is used mainly to define the immunity status of the patient before HSCT. The aim of our study was to examine the performance of polymerase chain reaction (PCR) and serologi...

Congenic mouse strains differing only at genes within the H-2 complex were found to have virus-specific cytotoxic effector cells in their spleens during or after recovery from Friend leukemia virus-induced splenomegaly. These effector cells were theta-positive T lymphocytes which functioned in vitro without help or inhibition by B lymphocytes or glass-adherent cells. The antigenic specificities...

One hundred seventy-five samples of fresh pork sausage representing thirty-five different commercial brands from six different retail stores were examined for the presence of salmonellae by standard enrichment, plating, biochemical and serological techniques. Contamination levels varied from 0 to 50% among stores and from 0 to 28% among brands. Prior research implied reduced prevalence of salmo...

An entomological and serological survey was performed in three localities of the Department of Concepción, Province of Corrientes, Argentina in 1998 and 1999, to identify triatomines species involved in domestic and wild transmission of Chagas disease. Triatomines were collected by man/hour capture in 32 houses randomly selected and 44 nearby outdoor ecotopes. Trypanosoma cruzi infection in tri...

The study is to evaluate the effect of age and sex on serological indices of Japanese quail (Coturnix coturnix japonica) reared in derived savanna area of Nigeria. A total of 200 quails comprising 100 each of male and female were selected for this study. Fifteen each of the males and females quails were randomly selected at each week of 6, 7, 8, 9, 10 and 11 respectively. Data were obtained on ...

BACKGROUND Presence at the same time of HBsAg and anti-HBs antibodies (HBsAg/Ab) is an entity sometimes encountered in chronic hepatitis B (CHB) carriers. OBJECTIVES This study was designed to characterize such serological profiles and to assess the reliability of serological marker quantification by three commercially available assays in this setting. STUDY DESIGN Among 2578 CHB identified...
