Specific interferon-gamma, IgA and IgM responses after experimental infection of neonatal calves with Cryptosporidium parvum.
Protozoan Antibody Formation Cattle Cryptosporidiosis Cryptosporidium parvum Feces Immunoglobulin A Immunoglobulin M Interferon-gamma Lymphocytes Time Factors Abstract: The in vitro interferon-gamma ...
Complete development of Cryptosporidium parvum in MDBK cells.
Cattle Cell Line Cryptosporidiosis Cryptosporidium parvum Kidney Microscopy, Electron parasitology Abstract: Sporozoites of Cryptosporidium parvum excysted in vitro from bovine oocysts were incubated with ...
Differential secretion of interleukin-8 by human epithelial cell lines upon entry of virulent or nonvirulent Yersinia enterocolitica.
chemotactic stimulus responsible for this accumulation is unknown, but several in vitro studies have demonstrated that epithelial cells secrete the chemokine interleukin-8 (IL-8), a potent chemoattractant of ...
A 33 kDa serine proteinase from Scedosporium apiospermum
Abstract: An extracellular proteinase produced by the filamentous fungus Scedosporium apiospermum has been purified and characterized. Initially, in vitro conditions for enzyme synthesis were investigated. ...
Typing of bovine attaching and effacing Escherichia coli by multiplex in vitro amplification of virulence-associated genes52
Abstract: Attaching and effacing Escherichia coli is a new causal agent of diarrhea in calves. Its major virulence factors are the intimin protein, encoded by the eaeA gene, and the Shiga-like toxins, encoded ...
In vitro susceptibilities of 176 clinical isolates of Streptococcus pneumoniae to 11 beta-lactams, erythromycin, and tetracycline36667
their in vitro susceptibilities to penicillin, ampicillin, amoxycillin with and without clavulanate, cefaclor, cefuroxime, cefonicid, cefprozil, cefpodoxime, cefotaxime, imipenem, tetracycline, and ...
Identification of DNA sequences recognized by VirF, the transcriptional activator of the Yersinia yop regulon.
vitro and that specifically binds to the promoter region of VirF-regulated genes. In this work, we determined the sequences of eight VirF-binding sites from four different genes, by DN ase I or hydroxyl ...
Typing of Clostridium perfringens by in vitro amplification of toxin genes54
effect in mice. However, this method requires specific antisera and a large number of mice. In this work, a new typing method was developed based on the amplification of toxin genes by polymerase chain ...
Mapping of TH1 helper T-cell epitopes on major secreted mycobacterial antigen 85A in mice infected with live Mycobacterium bovis BCG36652
complete mature 295-amino-acid (AA) protein were synthesized. Significant interleukin-2 (IL-2) and gamma interferon (IFN-gamma) secretion could be measured following in vitro stimulation of spleen cells with ...
Polymerase chain reaction-mediated cloning and in vitro translation of the genes coding for the structural proteins of hog cholera virus.
pestiviruses. By in vitro translation experiments we were able to demonstrate the protease activity of the p 20 protein of HCV. Health Topics: Animal health Category: A1 FOS Classification: 4.03 Veterinary ...
