Summary
Herpesvirus infection was identified in white and abdim storks. Lesions included enteritis, spleen necrosis, and liver necrosis, with inclusion bodies found in multiple organs.
Area of Science:
- Avian Pathology
- Veterinary Virology
- Herpesvirus Research
Background:
- Herpesvirus infections can cause significant morbidity and mortality in avian species.
- Understanding the pathological effects of herpesviruses in storks is crucial for conservation and disease management.
Purpose of the Study:
- To diagnose and characterize herpesvirus infection in white storks (Ciconia ciconia) and abdim storks (Ciconia abdimi).
- To describe the consistent pathological lesions and ultrastructural findings associated with the infection.
Main Methods:
- Histological examination of affected tissues.
- Electron microscopy for ultrastructural analysis of viral replication.
- Diagnosis in white storks (Ciconia ciconia) and abdim storks (Ciconia abdimi).
Main Results:
- Consistent lesions included haemorrhagic enteritis, splenic necrotic foci, and hepatic coagulative necrosis.
- Intranuclear inclusion bodies were observed in various cell types across multiple organs (digestive tract, spleen, liver, ovary, oviduct, lung).
- Ultrastructural analysis revealed characteristic herpesvirus replication sites within cell nuclei and intracytoplasmic virions.
Conclusions:
- Herpesvirus infection presents with distinct pathological findings in these stork species.
- The presence of inclusion bodies and viral replication sites confirms herpesvirus as the causative agent.
- This study contributes to the understanding of herpesvirus pathogenesis in large avian species.

01:18Bacterial Gastroenteritis
Bacterial gastroenteritis, characterized by diarrhea, abdominal cramps, and vomiting, is often caused by ingestion of contaminated food or water and is frequently associated with pathogenic Escherichia coli strains. These microbes exploit two principal mechanisms to inflict disease.Shiga toxin–producing E. coli, also referred to as STEC—notably O157:H7—release Shiga toxins that target ribosomes, blocking protein synthesis. The B subunit of the toxin binds the host glycolipid receptor...
01:27Cytomegalovirus Disease
Cytomegalovirus (CMV) disease is caused by human cytomegalovirus, a double-stranded DNA virus of the Herpesviridae family. While primary CMV infection is often asymptomatic in immunocompetent individuals, the virus can cause severe disease in neonates and immunocompromised patients. CMV is the most common cause of congenital viral infection in the United States, and a major pathogen in solid organ and hematopoietic stem cell transplant recipients.CMV is transmitted via bodily fluids, sexual...
01:25Arboviral Encephalitis
Arboviral encephalitis refers to brain inflammation caused by arthropod-borne viruses, particularly those transmitted through mosquito vectors. Among these, West Nile virus (WNV), a member of the Flaviviridae family, is a significant public health concern. WNV is an enveloped, positive-sense, single-stranded RNA virus. Human infection typically begins when an infected mosquito introduces the virus into the dermis during feeding. The primary transmission cycle involves birds as amplifying hosts...
01:28Herpes
Herpes simplex type 1 (HSV‑1) is a widespread pathogen responsible for orolabial lesions. It is an enveloped, double-stranded DNA (dsDNA) virus belonging to the family Herpesviridae. Once the virus infects a host cell, its double‑stranded DNA genome is delivered into the nucleus, where a coordinated cascade of immediate‑early, early, and late gene expression directs viral DNA replication, structural protein synthesis, and virion assembly. After primary infection of epithelial cells, HSV-1...
01:23Genital Herpes
Genital herpes is a sexually transmitted infection primarily caused by herpes simplex virus type 2 (HSV-2), though herpes simplex virus type 1 (HSV-1) is increasingly implicated in genital infections, particularly among younger populations. Transmission occurs mainly through sexual contact, with asymptomatic viral shedding serving as a major route of spread. This characteristic makes HSV-2 difficult to control at a population level, as individuals may unknowingly transmit the virus even in the...
00:57Viral Recombination
Cells are sometimes infected by more than one virus at once. When two viruses disassemble to expose their genomes for replication in the same cell, similar regions of their genomes can pair together and exchange sequences in a process called recombination. Alternatively, viruses with segmented genomes can swap segments in a process called reassortment.
