Background: Toxoplasmosis is one of the most frequent parasitic infections in animals causing reproductive disorders and thus notable economic losses in productivity. Among food animals, pigs along with sheep and goats possess the highest incidence of Toxoplasma gondii cysts in meat, and play a role as a source of human infection.
Methods: The commercial ELISA kit (PrioCHECK® Toxoplasma Ab SR, Prionics Schlieren-Zurich, Switzerland) for the detection of specific antibodies against T. gondii in swine serum was compared with a commercial IFAT (indirect fluorescent antibody test) (Toxo-Spot IF, bioMérieux, France), used as the reference test.
Results: The kappa value obtained comparing the results performed on sera by ELISA with the by IFAT was 1. By a receiver operating characteristics curve analysis, the commercial ELISA had a relative sensitivity of 100%, and a relative specificity of 100% respect to IFAT.
Conclusions: The commercial ELISA showed a very good agreement with the commercial IFAT in the detection of serum antibodies to Toxoplasma in pigs. Our study confirmed the usefulness of the commercial ELISA kit for the detection of antibodies against T. gondii in pigs, representing a valuable tool to improve the diagnostic activity for T. gondii in swine populations at the farm level or at the slaughterhouse, contributing to the control of this widespread infection.

An innovative magnetic immunoassay was developed for the voltammetric detection of carbohydrate antigen-125 (CA-125) on a home-made microfluidic device including a multisyringe pump, selection valve and magneto-controlled detection cell. Two kinds of biofunctionalized nanostructures including anti-CA-125 capture antibody-conjugated magnetic beads and anti-CA-125 detection antibody-labeled silver-polypyrrole (Ag-PPy) nanohybrids were utilized for a sandwiched immunoreaction in the presence of CA-125. With the help of an external magnet, the formed magnetic immunocomplexes were attached to the sensing interface to activate the electrical contact between Ag-PPy nanohybrids and the base electrode, thus resulting in the switching on of the sensor circuit for the generation of voltammetric signals thanks to electroactive Ag-PPy nanohybrids.

Introduction: The prevalence of anti-pertussis antibodies among infants and children in Iran has not been thoroughly investigated. Given that recommendations for booster vaccines are based on national disease epidemiology, we aimed to evaluate the seroprevalence of pertussis antibodies among infants and children in an Iranian referral hospital.
Materials And Methods: A total of 1012 infants and children were included in the study.
Toxoplasmosis is a significant food-borne protozoal disease in humans and animals. The study aimed to find out Toxoplasma seropositivity in sheep, estimate epidemiological risk factors and assess haemato-biochemical parameter changes. Blood samples were collected from 276 indigenous sheep in five districts surrounding Sulaymaniyah Province in the northern region of Iraq.

Newcastle disease (ND) is a notifiable avian disease responsible for several panzootics, which has resulted in the establishment of mandatory vaccination programs against the virus in several countries including Denmark. This study compared the immune response elicited in layers by the standard vaccination program for ND of a Danish commercial egg production facility with a simplified version of the vaccination program. A commercial flock of layers was followed for 77 weeks from hatching to culling.
