Twelve reference strains of mycoplasma and acholeplasma previously reported to have been recovered from cattle were tested against hyperimmune rabbit serum by counterimmunoelectrophoresis. This technique detected antigen by the formation of precipitin lines with antibody within 1 h and promises to be a useful technique for detecting and identifying mycoplasma isolates in either pure or mixed cu...

World health organization declared COVID-19 caused by SARS CoV-2 virus as a pandemic in early 2020. The target cells facilitating viral entry are ACE-2 receptor bearing like bronchial epithelial and pneumocytes. Children pose less risk compared to adults acquiring this disease mortality them is low due protective pathogenesis. with also at of developing unique immunological phenomena, known mul...

an inactivated agalactia vaccine was prepared with mycoplasma agalactiae in fermenter. the culture was inactivated and subsequently adjuvanted with aluminum hydroxide gel. four sheep and four goats were immunized with the experimental vaccine. two doses of 1ml of vaccine were administered three weeks interval. monthly, blood samples were taken from the vaccinated animals up to the fifth month a...

Clostridium (C.) difficile is a common cause of nosocomial diarrhea in horses. Vancomycin and metronidazole have been used as standard treatments but are only moderately effective, which highlights the need for a novel alternative therapy. In the current study, we prepared antiserum of equine origin against both C. difficile toxins A and B as well as whole-cell bacteria. The toxin-neutralizing ...

In the present study, the effect of anti-recombinant Streptococcus uberis adhesion molecule (SUAM) antibodies against S. uberis intramammary infections (IMI) was evaluated using a passive protection model. Mammary quarters of healthy cows were infused with S. uberis UT888 opsonized with affinity purified anti-rSUAM antibodies or hyperimmune sera. Non-opsonized S. uberis UT888 were used as a con...

Therapeutic antibodies can confer an instant protection against biothreat agents when administered. In this study, intact IgG and F(ab')2 from goat anti-ricin hyperimmune sera were compared for the protection against lethal ricin mediated intoxication. Similar ricin-binding affinities and neutralizing activities in vitro were observed between IgG and F(ab')2 when compared at the same molar conc...

I n contrast to the previous articles on the neuropathology of organism-related disorders, this article deals with inflammatory diseases that are not, as far as it is known, due to infections, but are most likely mediated by aberrant immune host reactions. Neurosarcoidosis should be regarded as a granulomatous, probably hyperimmune, inflammatory disorder, whereas paraneoplastic syndromes are as...

background: there are varieties of purification techniques for separation of human plasma proteins such as salting out, ion exchange chromatography, and ethanol fractionation. there are limitations for each method, for example in salting out method, the salt has to be removed in an additional step. ion exchange chromatography is difficult for scaling up, and plasma fractionation is a time consu...
