Continuous cell lines and immune ascitic fluid pools in arbovirus detection

Area of Science:

• Virology
• Cell Biology
• Public Health

Background:

• Arboviruses pose a significant threat, necessitating efficient detection methods.
• Accurate identification of arboviruses and their co-infections is crucial for disease control.

Purpose of the Study:

• To establish a reliable cell culture system for arbovirus isolation and detection.
• To evaluate the efficacy of hyperimmune ascitic fluids in identifying diverse arboviruses.

Main Methods:

• Utilized MOS61 (Aedes pseudoscutellaris) and Vero cell lines for arbovirus cultivation.
• Employed indirect immunofluorescence assays with hyperimmune ascitic fluids for virus detection.
• Tested 7 mixtures containing 10 reference viruses and specific immune fluids.

Main Results:

• The method successfully detected 70% of 80 African mosquito-borne arboviruses.
• The technique effectively identified arbovirus associations using monospecific or monoclonal immune fluids.
• Dengue virus serotypes 1-4 and yellow fever virus were readily detected.

Conclusions:

• The developed cell culture and immunofluorescence technique is effective for arbovirus detection and co-infection identification.
• This method supports systematic research and isolation of arboviruses, aiding in disease surveillance.
• The approach is valuable for identifying key arboviruses transmitted by mosquitoes in Africa.
