Aqui, apresentamos um protocolo para a detecção e quantificação de Plasmodium falciparum em infectados aquosas glóbulos vermelhos usando um espectrômetro infravermelho de reflexão total atenuada e análise multivariada de dados.

O objetivo geral deste procedimento é construir um modelo de regressão para a previsão da parasitemia da malária utilizando espectroscopia ATR-FTIR com análise de dados multivariados. Esse método pode ajudar a agilizar o diagnóstico de ponto de atendimento que pode ajudar a melhorar os resultados dos pacientes no futuro. A principal vantagem dessa técnica é que, embora o modelo possa levar algum tempo para ser construído, ele é altamente portátil, fácil de usar, altamente sensível e de baixo custo.

Embora este método permita a quantificação de parasitas da malária, também pode ser usado para observar a resposta fenotípica a mudanças ambientais, como alterações na composição de parasitas devido a agentes antimicrobianos. A ideia desenvolveu-se a partir do trabalho que fizemos no Síncrotron Australiano em células infectadas pela malária. Isso foi no nível de célula única.
