The present study involves the synthesis, characterization and immunogenicity of Gold Nanoparticle (GNP) conjugated recombinant AprV2 protein of Dichelobactor nodosus. To achieve this, GNPs of size 20 nm were prepared and characterized. The gold nanoparticles effectively adsorbed 3.3 μg of recombinant AprV2 protein over the surface. TEM studies revealed corona of AprV2 over GNPs (1-2 nm thick) in GNPs-AprV2 conjugate. Further, GNP-AprV2 conjugate revealed a red shift from 523 nm to 532 nm, indicating increased size of GNPs after conjugation with AprV2. To evaluate the immunogenic response, mice were allotted to 5 different groups. Mice in group I injected with GNP-AprV2 conjugate, group II with GNP-AprV2 with MPLA (Monophosphoryl lipid A), group III with AprV2 on its own, group IV with GNPs and group V with Phosphate Buffered Saline (PBS). The highest antibody responses against the AprV2 were recorded in pooled sera from mice of group II compared to group me and III on day 28. Among all groups, the group II mice vaccinated with GNP-AprV2/ MPLA exhibited the highest IgG levels. The third dose of vaccine formulations did not enhance antibody levels. This study is a first report studying the immunogenic effect of conjugation of GNPs with rAprV2 of D. nodosus.

Kounis syndrome also known as allergic angina syndrome is defined as the occurrence of an acute coronary syndrome concomitantly with hypersensitivity reaction. It was first described in 1991 by Kounis and Zavras. It is a rare syndrome and is often an under diagnosed phenomenon as physicians are unaware of the condition. We discuss a 54 years old female Sri Lankan patient who developed Kounis syndrome following Oxford Astra Zeneca COVID-19 vaccination. The patient initially developed anaphylaxis following the Astra Zeneca COVID-19 vaccine and subsequently developed acute coronary syndrome secondary to anaphylaxis. Patient was treated appropriately and eventually recovered from her condition. This syndrome should be suspected when there is concurrent acute coronary syndrome with allergic reactions. Care givers should be aware of its pathophysiology as treatment of either of the two may worsen the other injury.

The field of parasitology is undergoing a transformative shift propelled by the integration of cutting-edge technologies collectively known as immuno-omics. This paradigm shifts combines immunology with various omics disciplines, such as genomics, transcriptomics, proteomics, and metabolomics, to unravel the complex interactions between parasites and their hosts. This article explores the Immuno-omic Revolution and its impact on the study of parasite immunology, shedding light on how these integrative technologies are reshaping our understanding of host-parasite interactions and paving the way for innovative strategies in disease control.
