conclusions disseminated bcg infection should be considered in the differential diagnosis of infants and young children with fever, hepatosplenomegaly, lymphadenopathy, and history of bcg vaccination. the pcr method has a high positivity rate and can serve as a useful tool for the rapid and specific identification of m. bovis bcg substrain infection. results from the total of 34 children hospit...
the (bacille calmette-gue´rin) bcg is widely practiced in many countries in pediatric group and is a part of routine vaccination program at birth in ir. iran for prophylaxis against tuberculosis, but its efficacy is a matter of debate in different geographic and ethnic regions. adverse reactions induced by bcg vaccination ranges from bcg adenitis, osteitis, and cold abscess at vaccination site ...
Interleukin 12 receptor beta 1 (IL12Rβ1) deficiency is the most common cause of Mendelian susceptibility to mycobacterial disease (MSMD). MSMD usually predisposes affected individuals infections with weakly virulent mycobacteria such as Bacille Calmette-Guérin (BCG), environmental mycobacteria, non-typhoidal Salmonella, and certain other intracellular pathogens. presents disseminated BCG infect...
Salmonella typhimurium infection in swine causes an enterocolitis followed by a persistent carrier state, but little is known about the mechanisms that allow this organism to colonize and persist in host tissues. Neutrophils provide a first line of defense against invading pathogens such as Salmonella typhimurium. The purpose of this study was to evaluate porcine neutrophil function after in vi...
Natural resistance to infection with Salmonella typhimurium in mice is controlled by two major loci, Bcg and Lps, located on mouse chromosomes 1 and 4, respectively. Both Bcg and Lps exert pleiotropic effects and contribute to cytostatic/cytocidal activities of the macrophage. Bcg encodes for a membrane phosphoglycoprotein designated Nrampl (natural resistance-associated macrophage protein 1), ...
The clinical phenotype of interleukin 12 receptor beta1 chain (IL-12Rbeta1) deficiency and the function of human IL-12 in host defense remain largely unknown, due to the small number of patients reported. We now report 41 patients with complete IL-12Rbeta1 deficiency from 17 countries. The only opportunistic infections observed, in 34 patients, were of childhood onset and caused by weakly virul...
Administration of small amounts of salmonella endotoxin (20 microg.) or of acetone-extracted BCG cells (100 microg.) increases the resistance of mice to infection with Myco. fortuitum as well as their ability to clear carbon particles from their blood stream. Whereas the increased resistance to infection persists for many weeks, the clearing power returns to a normal level within a few days. Wh...
Background: Disseminated bacilli calmette-Guerin (BCG) infection after inoculation with live vaccine is considered to result from impaired immunity of the child. However, half of the cases are regarded as idiopathic because no well-defined immunodeficiency condition can account for the infection. Case report: An 8-month-old male infant was admitted with an ulcer on his left arm at the site ...
Virulent strains of Salmonella opsonized with normal mouse plasma are never phagocytosed as well as avirulent strains. The virulent strains of Salmonella phagocytosed after opsonization with normal mouse plasma are able to multiply within normal mouse peritoneal macrophages, whereas under similar experimental conditions the avirulent strains are killed. When virulent strains of Salmonella are o...
