Antileishmanial effects, cellular mechanisms, and cytotoxicity of Elettaria cardamomum essential oil against Leishmania major infection
Trop Biomed. 2023 Jun 1;40(2):259-265. doi: 10.47665/tb.40.2.019.ABSTRACTLeishmaniasis is an infectious disease with various clinical manifestations. We studied the therapeutic effects of Elettaria cardamomum essential oil (ECEO) against Leishmania major infection. In vitro effects of ECEO against L. major were examined by MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) and macrophage assays. Nitric oxide (NO) production, infection inhibition in macrophages, and the apoptotic activity of ECEO in treated parasites were also measured. By calculating the 50% cytotoxic concentrations (CC50), we studied the c...

Theileria orientalis Buffeli pathotype in cows in a theileriosis-endemic region of India
Trop Biomed. 2023 Jun 1;40(2):236-240. doi: 10.47665/tb.40.2.015.ABSTRACTOriental theileriosis caused by Theileria orientalis is a growing health concern of lactating cows in its endemic areas. Rapid and sensitive diagnostic tests are demand areas for appropriate and effective prophylactic and therapeutic measures. Quantitative polymerase chain reaction (qPCR) is the answer for both detection and quantification of parasites. Present study deals with qPCR for detection of parasitemia level of T. orientalis in apparently healthy and clinically affected cows. Major piroplasm surface protein (MPSP) gene present in T. orientali...

An automated malaria cells detection from thin blood smear images using deep learning
Trop Biomed. 2023 Jun 1;40(2):208-219. doi: 10.47665/tb.40.2.013.ABSTRACTTimely and rapid diagnosis is crucial for faster and proper malaria treatment planning. Microscopic examination is the gold standard for malaria diagnosis, where hundreds of millions of blood films are examined annually. However, this method's effectiveness depends on the trained microscopist's skills. With the increasing interest in applying deep learning in malaria diagnosis, this study aims to determine the most suitable deep-learning object detection architecture and their applicability to detect and distinguish red blood cells as either malaria-i...

Post-COVID-19 cryptosporidiosis: A serious risk or mere association?
This study analyzed gastrointestinal symptoms, medical histories, fecal Cryptosporidium oocysts, and the history of COVID-19 infection in patients who attended the Faculty of Medicine, Cairo University, from January to July 2021. Fecal biomarkers, including H. pylori, occult blood, fecal calprotectin (FCAL), and TNF-a, were measured, and Cryptosporidium spp. genotypes were molecularly characterized among post-COVID-19 patients using RFLP. Preliminary results from 210 post-COVID-19 patients revealed that group 1 (Cryptosporidiumpositive) (n = 49) and group 2 (Cryptosporidium-negative) (n = 161) showed no significant differe...
