Abstract We detected severe acute respiratory syndrome coronavirus 2 in an otherwise healthy poodle living with 4 family members who had disease. observed antibodies serum samples taken from the dog, indicating seroconversion. Full-length genome sequencing showed that canine and human viruses were identical, suggesting human-to-animal transmission.

To investigate the seroprevalence of leptospiral infection in sheep in Ahvaz, southwestern Iran, bloodsamples were taken from 181 female sheep. Sera were stored at -20°C until use. They were initially screenedat serum dilution of 1:100 against six live antigens of Leptospira interrogans serovars pomona, canicola,hardjo, ballum, icterohaemorrhagiae, grippotyphosa using the microscopic agglutinat...

BACKGROUND Despite the uncertainty in the diagnosis of neuropsychiatric involvement in systemic lupus erythematosus (SLE), attempts have been made to record the association of certain antibodies in serum with neuropsychiatric (NP) manifestations. We aimed to assess the behaviour and the association of serum and cerebrospinal fluid (CSF) autoantibodies with NP manifestations in SLE patients (NPS...

Many assays for detection of antibodies against porcine epidemic diarrhea virus (PEDV) are based on detection of neutralizing antibodies or immunoglobulin (Ig) G in serum samples. However, due to the particular features of the mucosal immune system, presence of serum antibodies against enteric pathogens, such as PEDV, not always correlates with protection. In contrast, anti-PEDV IgA antibodies ...

Glycosylation is a protein post translational modification which plays important role in protein function, stabilization, trafficking, and turnover. Alteration of protein glycosylation is a common phenomenon during tumor progression, migration, invasion, angiogenesis, as well as metastasis. Hence, aberrant glycan structures and the induced corresponding anti-carbohydrate antibodies are potentia...

An insoluble specific adsorbent for anti-human serum albumin antibodies was prepared by coupling human serum albumin (H.S.A.) to polystyrene by azo bonds. Rabbit anti-H.S.A. immune serum was passed through a column of the adsorbent. It was shown that different volumes of the immune serum were required for the saturation of the different determinant groups of H.S.A. by their corresponding antibo...

1. Antibodies can be extracted from the brain and spinal cord of rabbits actively or passively immunized with typhoid bacilli. 2. The titers of the antibodies in the extracts of brain and cord depend upon the titer of the blood serum. In actively immunized rabbits the following numerical relationships exist between the titers of the serum and of these organ extracts: The ratio of the titer of t...

Abstract Objectives During the current pandemic, antibody testing based on venous serum helps to determine whether tested person has been previously infected with SARS-CoV-2. Alternatively, capillary blood can be taken via a finger prick (dried spots, DBS). In this study, paired DBS and venipuncture samples were using two serological assays evaluate usability of for detection anti-SARS-CoV-2 an...
