Canine angiostrongylosis, caused by the nematode Angiostrongylus vasorum, is an emerging cardiopulmonary disease in Europe which can be fatal if left untreated. We determined the diagnostic value of the specific detection of antibodies against A. vasorum adult somatic antigen, adult excretory/secretory (E/S) antigen and first stage larvae (L1) somatic antigen in ELISAs. Also, A. vasorum adult s...
The conversion of Salmonella anatultr (group Et, somatic antigens 3, 10) to group I& (antigens 3, 15) by infection with phage cl5 and its virulent mutant P vir has been analyzed. Antigen 15 appears in the cells within a few minutes after infection with either phage. The receptors for another phage, ear, which can be adsorbed only by cells with antigen 15, appear with the new antigen. The recept...
BACKGROUND The clinical course of tuberculosis (TB) infection, bacterial load and the morphology of lesions vary between pulmonary and extrapulmonary TB. Antigens expressed in abundance during infection could represent relevant antigens in the development of diagnostic tools, but little is known about the in vivo expression of various M. tuberculosis antigens in different clinical manifestation...
Escherichia coli O157:H7 is an important human pathogen causing haemorrhagic colitis, haemolyticuraemic syndrom and thrombotic thrombocytopenic purpura. In this study, 100 ground beef samples were collected randomly from beef markets in June 2004. For isolation of the bacteria, samples were firstly enriched in modified trypticase soy broth, followed by plating onto sorbitol MacConkey agar sup...
Neoplastic lesions typically express specific carbohydrate antigens on glycolipids, mucins, and other glycoproteins. Such antigens are often under epigenetic control and are subject to reversion and loss upon therapeutic selective pressure. We report here that two of the most common tumor-associated carbohydrate antigens, Tn and sialyl Tn (STn), result from somatic mutations in the gene Cosmc t...
In this study 130 bulk tank milk samples which were delivered to the Pegah Pasturisation Factory inMashhad were collected randomly during the summer months. Samples were firstly enriched in modifiedtrypticase soy broth containing novobiocin, followed by plating onto sorbitol MacConkey agar supplementedwith cefixime and potassium tellurite for isolation of Escherichia coli O157:H7. Consequently ...
