Article Synopsis
  • The study focuses on the sexually transmitted protozoan parasite that typically infects women and explores the efficacy of cinnamaldehyde, carvacrol, and thymol—components of cinnamon and thyme essential oils—against metronidazole-resistant strains of the parasite.
  • Using clinical isolates and a resistant reference strain, the researchers determined the minimum inhibitory concentrations (MIC50) and evaluated the interactions between these essential oil components and metronidazole through various testing methods.
  • Results indicated that cinnamaldehyde was the most effective component, showing synergy with metronidazole which may allow for lower doses to minimize side effects and combat resistance, thus potentially enhancing treatment outcomes.

The leishmaniasis are a group of vector-borne diseases caused by a protozoan parasite from the genus Leishmania. In this study, a series of thiazolopyrimidine derivatives were designed and synthesized as novel antileishmanial agents with LmPTR1 inhibitory activity. The final compounds were evaluated for their in vitro antipromastigote activity, LmPTR1 and hDHFR enzyme inhibitory activities, and cytotoxicity on RAW264.

Laboratory diagnosis of leishmaniasis is based on culture, microscopic examination, serological and molecular methods. The gold standard method is to see amastigotes in microscopic examination and to grow promastigotes in Novy, MacNeal, Nicolle (NNN) medium. NNN medium is frequently used for culture all over the world.

Article Synopsis
  • * The study involved five isolates from chronic CL patients, using real-time PCR for genotyping and drug efficacy tests to evaluate the effectiveness of miltefosine and meglumine antimoniate against the disease.
  • * Results indicated that miltefosine effectively killed the promastigotes at specific concentrations, and since there are few studies on miltefosine's effects on CL patients, further research is recommended to enhance treatment strategies for this condition.

Article Synopsis
  • Leishmaniasis, caused by the Leishmania protozoa, affects around 12 million people across 98 countries, particularly in tropical and subtropical regions, with 1.2 million new cases reported yearly and rising drug resistance complicating treatment.
  • Recent research has focused on plant-derived substances as potential anti-leishmanial agents, with this study investigating the effects of extracts from Prangos ferulacea and Ferula orientalis against Leishmania tropica.
  • The results indicate that certain extracts from these plants exhibit significant cytotoxic activity against L.tropica, with P. ferulaceae showing the lowest IC50 values and specific extracts also impacting non-target mammalian cells.

Objectives: Leishmaniasis is a vector-borne disease and dogs may act as urban reservoirs. Turkey and most of the Mediterranean basin countries are endemic for leishmaniasis. In this study, it is aimed to report the autochthonous leishmaniasis cases, with all the components of the infection cycle (reservoir, vector, and the host) in a region close to Europe.

Leishmaniasis is an infectious disease in which different clinical manifestations are classified into three primary forms: visceral, cutaneous and mucocutaneous. These disease forms are associated with parasite species of the protozoan genus Leishmania. For instance, Leishmania infantum and Leishmania tropica are typically linked with visceral (VL) and cutaneous (CL) leishmaniasis, respectively; however, these two species can also cause other form to a lesser extent.

Microscopic methods are accepted as the gold standard in the diagnosis of malaria and in the followup of treatment. However, as the microscopical methods require experienced personnel, it is important to confirm the diagnosis with a different method for accurate diagnosis and treatment follow-up. In our study, we aimed to investigate the utility of the use of real time reverse transcriptase polymerase chain reaction (rRT-PCR), as well as microscopic methods for malaria treatment follow-up.

Objective: In present times, malaria remains an infectious disease with a high mortality rate in some regions of the world. It is predicted to preserve its importance as a disease in the future because of the traveling human populations from malaria-endemic African countries into the regions where malaria has been eradicated. The objective of this study is to evaluate the increasing imported malaria cases in the Turkish Republic of Northern Cyprus.
