Two outer membrane proteins are bovine lactoferrin-binding proteins in Mannheimia haemolytica A1
Mannheimia haemolytica is a Gram negative bacterium that is part of the bovine respiratory disease, which causes important economic losses in the livestock industry. In the present work, the interaction between M. haemolytica A1 and bovine lactoferrin (BLf) was studied. This iron-chelating glycoprotein is part of the mammalian innate-immune system and is present in milk and mucosal secretions; ...
متن کاملAn electrophoretic characterization of iron-transporting proteins in Mannheimia haemolytica A1.
Iron-regulated outer membrane proteins (IROMPs) in Mannheimia haemolytica A1, which function as a receptor for complexes containing iron ions, are induced by iron deficiency in the growth environment of the bacteria. Densitometric analysis of SDS-PAGE separation showed expression of IROMPs of 71, 77, and 100 kDa in the case of bacteria grown in a medium with 2,2-dipyridyl. The electrophoregrams...
متن کاملAnalysis of in vivo expressed genes in Mannheimia haemolytica A1.
The expression of Mannheimia haemolytica A1 genes during in vivo growth was examined by reverse transcriptase-polymerase chain reaction (RT-PCR) using total RNA extracted directly from M. haemolytica A1 recovered from pneumonic lungs of cattle. Primers specific for three groups of genes were used. Group 1 includes virulence-related genes: lktC, tbpB, ahs, nmaA, gs60 and gcp. Group 2 includes ge...
متن کاملGenome Sequences of Mannheimia haemolytica Serotype A1 Strains D153 and D193 from Bovine Pneumonia
Here we report two genome sequences, one complete and one draft, from virulent bovine strains of Mannheimia haemolytica serotype A1 recovered prior to the field usage of modern antimicrobial drugs.
متن کاملLactoferrin-binding proteins in Shigella flexneri.
The ability of Shigella flexneri to interact with lactoferrin (Lf) was examined with a 125I-labeled protein-binding assay. The percent binding of human lactoferrin (HLf) and bovine lactoferrin (BLf) to 45 S. flexneri strains was 19 +/- 3 and 21 +/- 3 (mean +/- standard error of the mean), respectively. 125I-labeled HLf and BLf binding to strain M90T reached an equilibrium within 2 h. Unlabeled ...
