newcastle disease virus (ndv) is known as one of the most important endemic viral pathogen for various avian species such as ostrich, in iran. therefore, establishing a routine vaccination program against nd in ostrich flocks would be useful in order to reduce the danger of this infection. newcastle disease occurs among the ostriches and leads to high rate of mortality while most of the losses ...

black leg has been reported in a variety of animals, but is ofthe most importance in cattle and sheep. a20 days old holsteindairy calf was examined because of anorexia and lameness from2 days ago. the calf was depressed, tachypneic, tachycardic, andhad a body temperature of 38.5ºc. both hind limbs proximal tothe tarsal joint were markedly swollen, firm and painful. nocrepitation was noted on pa...

Abstract Maternal and cord blood sera were collected from 20 parturients who received the BNT162b2 vaccine. All women infants positive for anti S- anti-receptor binding domain antibody–specific immunoglobulin G. Cord antibody concentrations correlated to maternal levels time since vaccination. Antenatal severe acute respiratory syndrome coronavirus 2 vaccination may provide neonatal protection.

Abstract Maternal antibody-mediated fetal red blood cell destruction secondary to non-D Rh system antibodies is a significant cause of hemolytic disease the fetus and newborn. Here, we report rare case severe perinatal associated with maternal antibody e antigen. In addition anemia, infant developed hyperbilirubinemia. Resolution infant’s anemia hyperbilirubinemia occurred after treatment photo...

  Newcastle disease virus (NDV) is known as one of the most important endemic viral pathogen for various avian species such as ostrich, in Iran. Therefore, establishing a routine vaccination program against ND in ostrich flocks would be useful in order to reduce the danger of this infection. Newcastle disease occurs among the ostriches and leads to high rate of mortality while most of the losse...

AIM To determine the influence of placental malaria, maternal HIV infection, and maternal hypergammaglobulinaemia on transplacental IgG antibody transfer. METHODS One hundred and eighty materno-neonatal pairs from a Malawian population were assessed. Cord and maternal serum samples were tested for total serum IgG antibody titres using nephelometry, and for specific IgG antibody titres to Stre...

In order to estimate the mean of maternal antibody in calves against BHV-1 (Bovine Herpes virus type 1), this study was carried out in a population of calves from non-vaccinated dairy cattle at 2 livestock in Qazvin province. One hundred thirteen sera out of 512 were collected from 1-4 months unvaccinated calves. We used Blocking –Percentage of maternal antibodies against BHV-1, which obtained ...

Bovine viral diarrhoea virus (BVDV) contributes significantly to health-related economic losses in the beef and dairy industry. Antibodies of maternal origin can be protective against BVDV infection, however, calves with low titres of maternal antibody or that do not receive colostrum may be at risk for acute BVDV infection. Interference by high titres of maternal antibodies prevents the develo...

Maternal antibodies protect chicks from infection with pathogens early in life and may impact pathogen dynamics due to the alteration of the proportion of susceptible individuals in a population. We investigated the transfer of maternal antibodies against avian influenza virus (AIV) in a key AIV host species, the mallard (Anas platyrhynchos). Combining observations in both the field and in mall...
