HUMAN BABESIOSIS: A GENERAL REVIEW WITH SPECIAL REFERENCE TO EGYPT
Journal of the Egyptian Society of Parasitology
|March 5, 2016
Summary
Babesiosis is a tick-borne illness caused by Babesia parasites, often asymptomatic but can cause severe disease in vulnerable populations. Early diagnosis and treatment are crucial to prevent complications and blood transmission.
Area of Science:
- Medical Entomology
- Parasitology
- Infectious Diseases
Background:
- Babesiosis is a tick-borne illness caused by protozoan parasites of the genus Babesia.
- It is a malaria-like disease with a worldwide distribution, affecting humans as opportunistic hosts.
- Increasing reported cases may reflect higher incidence and improved disease awareness.
Purpose of the Study:
- To review the current understanding of babesiosis, including its transmission, diagnosis, and clinical impact.
- To highlight babesiosis as a confounding factor in Lyme disease diagnosis and a threat to blood safety.
- To emphasize the role of advanced diagnostic tools in identifying new Babesia species and understanding their biology.
Main Methods:
- Literature review of babesiosis research, focusing on epidemiology, clinical presentation, and diagnostics.
- Analysis of diagnostic challenges, including the importance of parasitemia levels and laboratory expertise.
- Consideration of molecular tools like PCR assays for enhanced detection and species characterization.
Main Results:
- Babesiosis is transmitted by various tick vectors globally.
- While often asymptomatic in healthy individuals, it can lead to significant morbidity and mortality in the elderly, immunocompromised, or asplenic patients.
- Advanced diagnostic methods, such as PCR, improve detection sensitivity and aid in discovering new species.
Conclusions:
- Babesiosis poses a significant medical challenge, impacting Lyme disease diagnosis and posing a risk to blood transfusion safety.
- Accurate diagnosis requires high clinical suspicion and skilled laboratory personnel.
- Treatment is recommended for all diagnosed cases to prevent sequelae and transmission, alongside tick-bite prevention advice.

Symbiotic relationships are long-term, close interactions between individuals of different species that affect the distribution and abundance of those species. When a relationship is beneficial to both species, this is called mutualism. When the relationship is beneficial to one species but neither beneficial nor harmful to the other species, this is called commensalism. When one organism is harmed to benefit another, the relationship is known as parasitism. These types of relationships often...

Alveolates are a group of organisms recognized by the presence of alveoli, which are cytoplasmic sacs located beneath the cell membrane. While their function remains uncertain, alveoli may help regulate water balance by controlling how much water enters and leaves the cell. In dinoflagellates, these structures may serve as armor plates. There are three major types of alveolates: ciliates, which move using cilia; dinoflagellates, which use flagella for movement; and apicomplexans, which are...
