Summary
Six cases of camel prion disease were identified in dromedary camels in Tunisia, indicating the disease is widespread in North Africa. Further investigation into its spread and risks is crucial.
Area of Science:
- Veterinary Neurology
- Prion Diseases
- Zoonotic Disease Research
Background:
- Camel prion disease (CPD) is a fatal neurodegenerative disorder affecting dromedary camels.
- Previous reports of CPD have been limited, with its geographic distribution poorly understood.
- Understanding CPD epidemiology is vital for animal health and potentially public health.
Purpose of the Study:
- To report new cases of camel prion disease in dromedaries.
- To confirm the presence and extent of CPD in North Africa.
- To emphasize the need for ongoing surveillance and research.
Main Methods:
- Neurological examination of affected dromedaries.
- Post-mortem analysis of brain and lymphoid tissues.
- Detection of disease-associated prion protein (PrPSc) using immunohistochemistry.
Main Results:
- Six cases of CPD were diagnosed in dromedary camels in Tunisia.
- Affected animals exhibited characteristic neurological signs.
- PrPSc accumulation was confirmed in both brain and lymphoid tissues, suggesting systemic involvement.
Conclusions:
- Camel prion disease is confirmed to be present and widespread in dromedary populations in Tunisia, North Africa.
- The findings underscore the necessity of active surveillance programs for CPD.
- Further research into CPD epidemiology, transmission routes, and public health implications is warranted.

Toxoplasmosis
Toxoplasmosis, a zoonotic disease caused by the protozoan Toxoplasma gondii, poses significant public health challenges globally due to its high seroprevalence and varied clinical manifestations. As an obligate intracellular parasite, T. gondii can infect all warm-blooded vertebrates, but felids are its only definitive hosts, shedding unsporulated oocysts into the environment. Humans typically acquire the infection through ingestion of tissue cysts in undercooked meat or oocysts from...
American Trypanosomiasis
Chagas disease, or American trypanosomiasis, is a vector-borne parasitic infection caused by Trypanosoma cruzi, a flagellated protozoan (kinetoplastid) of the family Trypanosomatidae. The disease is endemic in Latin America, although cases are increasingly reported worldwide due to human migration. Transmission most commonly occurs when feces of infected triatomine bugs contaminate bite wounds or mucosal surfaces; additional routes include congenital, transfusional, transplant-related, and oral...
Rabies
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...
Poliomyelitis
Poliomyelitis is caused by poliovirus, a small, non-enveloped, positive-sense RNA virus of the Picornaviridae family and Enterovirus genus. Transmission occurs primarily via the fecal-oral route, often through ingestion of contaminated water or food. The virus initially replicates in the oropharynx and intestinal mucosa, particularly in lymphoid tissues such as the tonsils, Peyer’s patches, and regional lymph nodes. Primary viremia follows, allowing dissemination throughout the body.In most...
Huntington Disease l: Introduction
Huntington disease or HD is a progressive, fatal neurodegenerative disorder inherited in an autosomal dominant pattern.PathophysiologyIt is caused by expansion of the CAG trinucleotide repeat in the HTT gene on chromosome 4 (4p16.3), producing an abnormal huntingtin protein with an expanded polyglutamine tract. This misfolded protein disrupts cellular function, leading to neuronal death. Normal alleles have ≤26 repeats, 27–35 are intermediate (risk of expansion), 36–39 show reduced penetrance,...
Rocky Mountain Spotted Fever
Rocky Mountain Spotted Fever (RMSF) is a severe tick-borne illness caused by Rickettsia rickettsii, a Gram-negative, coccobacillary bacterium. This pathogen is an obligate intracellular parasite, requiring a host cell for replication. Transmission occurs through the bite of an infected tick. In the United States, the most important vectors are Dermacentor variabilis (American dog tick) and Dermacentor andersoni (Rocky Mountain wood tick), though other tick species may also serve as vectors.
