Summary
Two foals diagnosed with verminous encephalomyelitis caused by Angiostrongylus cantonensis larvae. This parasitic infection led to progressive neurological deficits, including tetraparesis, in the affected horses.
Area of Science:
- Veterinary Neurology
- Parasitology
- Equine Pathology
Background:
- Verminous encephalomyelitis is a serious neurological condition in foals.
- Parasitic larval migration can cause significant central nervous system (CNS) damage.
Observation:
- Two foals presented with tetraparesis and progressive, multifocal neurological signs.
- Initial diagnosis considered Strongylus vulgaris larval migration.
Findings:
- Necropsy and histopathology confirmed Angiostrongylus cantonensis larvae in the CNS of both foals.
- Intact adult larvae of A. cantonensis were recovered from the spinal cord of one foal.
Implications:
- Highlights A. cantonensis as a potential cause of equine encephalomyelitis.
- Emphasizes the importance of considering diverse parasitic etiologies in equine neurological disease.
- Suggests diagnostic challenges in differentiating parasitic CNS infections in foals.

01:28Rabies
Rabies is a lethal zoonotic disease caused by a single-stranded, negative-sense RNA virus of the Lyssavirus genus, within the family Rhabdoviridae. Its primary mode of transmission to humans is through bites or saliva-contaminated scratches from infected mammals such as dogs, bats, raccoons, or foxes. Transmission can also occur if infectious saliva contacts abraded skin or intact mucous membranes, including the conjunctiva.Viral Entry and Early ReplicationOnce introduced at the bite or scratch...
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...
01:26Encephalitis ll: Pathophysiology
Encephalitis is inflammation of the brain parenchyma caused by direct viral invasion or immune-mediated mechanisms triggered by infections or tumors. Both processes lead to neuronal injury, disrupted neurotransmission, and diverse neurological symptoms, often with overlapping clinical and pathological features.Autoimmune EncephalitisIn autoimmune encephalitis, antibodies target neuronal antigens on cell surfaces, synapses, or within neurons. A key example is anti-NMDAR encephalitis, which can...
