Leishmaniasis is a spectrum of disease caused by the infection of protozoan parasite Leishmania mainly affecting the antigen presenting cell of the host. The disease is although considered as neglected tropical disease still it is not completely eradicated. Majority of the issues related to the ther...apeutic approach is due to increased cytotoxicity of the drugs, less effectiveness, high cost and occurrence of drug resistance. Therefore, recent advancement in the field of parasitology has taken into consideration of the specific arms of immunity which can be triggered with the help of natural products, synthetic molecules or parasite specific ligands which helps in the restoration of host protective immunity and recovery from the infection. Therefore, in this review, we have highlighted the recent advancement in the field of Leishmania research taken into consideration of the therapeutic perspective. We have shown that apart from therapeutic potential of the available drugs and vaccination approach, the immune-therapy are emerging as the modern regime of treatment where the effectiveness of the therapy is significantly increased and making it safer and promising.

Little progress has been made since the 1960s and 1970s to widen the therapeutic arsenal against Trypanosoma cruzi, the causative pathogen of Chagas disease, which remains a frustrating and perplexing infectious disease. This chapter focuses on the strategic and operational challenges in the clinica...l drug development of a novel antitrypanosomal agent for Chagas disease. The various elements that contribute to a robust assessment of treatment effect including dose selection, choice of patient population, trial methodology, endpoint measures, and regulatory perspectives are discussed. The learnings herein should serve as resource to help researchers and other stakeholders optimize their clinical development plans and speed delivery of new medicines to patients with Chagas disease.

To meet the need for laboratory diagnosis to be integrated in community care, the new 2022 Update describes point-of-care tests that can be performed both in district laboratories and peripheral healthcare facilities by non-specialist staff. Also included are recently developed self-tests.
This document is a guide defining requirements for quality and safety for malaria rapid diagnostic testing services to safeguard the quality of the results, the safety of the operators and patients and that of the environment for use by national malaria control programmes, regulators, implementers a...nd rapid diagnostic providers.

In 2007, the Sixtieth World Health Assembly adopted resolution WHA60.13 on control of leishmaniasis, urging Member States, among other actions:
to strengthen prevention, active detection and treatment of cases of both cutaneous and visceral leishmaniasis in order to decrease the disease burde...n; and
to strengthen the capacity of peripheral health centres to deliver primary and secondary care, so that they provide appropriate affordable diagnosis and treatment and act as sentinel surveillance sites.

Health ministries currently lack effective tools for monitoring and evaluation of schistosomiasis control programmes. Egg detection can be used, but the cost, challenges of obtaining samples, and the need for trained personnel and equipment limit the frequency of monitoring. The purpose of this TPP ...is to guide the development of new diagnostic tools to reliably measure when prevalence is above or below a cut-off of 10% in school-aged children. Communities remaining above 10% require annual MDA, while communities below 10% can reduce MDA frequency as long as < 10% prevalence can be maintained. However, the lack of a reliable test has hindered the development of maintenance strategies. The test is also needed to track changes of prevalence > 10% to ensure that annual MDA is reducing overall prevalence.

The meeting addressed the last key area, that is, determining the best method or combination of diagnostic methods for a control programme for S. stercoralis infections in humans.
Dr Montresor’s presentation highlighted that while there is currently no “gold standard” for the... diagnosis of S. stercoralis, there is a felt urgency to optimize diagnostic regimens that are currently available, and in the context of population-based testing (as opposed to individual focused diagnostics in clinical settings).
In other words, the diagnostic test(s) should have good accuracy, but we should remember that in public health we do not aim at individual diagnosis: rather, we need a tool that should help to estimate the prevalence in a population.

Estas Pranchas para o diagnóstico microscópico da malária servem como guia para laboratoristas e técnicos de campo responsáveis por diagnóstico microscópico da malária pelo método de Giemsa. Também devem ser úteis para professores e alunos de disciplinas correlatas. As pranchas mostram fo...tomicrografias coloridas de lâminas de sangue (esfregaços e gotas espessas), coradas, e texto explicativo sobre as quatro espécies de parasitos causadores da malária humana e sua morfologia. São fornecidas descrições completas de cada espécie, bem como instruções sobre o preparo de lâminas e esfregaços, o uso de soluções tampão, o método de coloração Giemsa, o exame das lâminas e procedimentos para estimar a densidade parasitária. Nada será adicionado sobre knowlesi e simium? Acho importante até para que as pessoas saibam com o que se parecem. Também são descritos outros elementos celulares observados no sangue, bem como vários contaminantes comuns que podem ser confundidos com parasitos da malária.

Este manual (Parte I dos módulos de capacitação em Bases do diagnóstico microscópico da malária) ajudará os participantes durante seu treinamento em diagnóstico microscópico da malária humana. O manual foi concebido como base para um treinamento formal de quatro a cinco semanas de duraçã...o e destina-se a alunos com conhecimentos rudimentares de ciência. Ao concluir a capacitação, o aluno será responsável pelo diagnóstico de malária com lâminas de sangue de casos suspeitos na sua comunidade. Desse modo, decisões importantes referentes ao tratamento dependem da sua competência em garantir o diagnóstico de malária sem supervisão.

O volume de capacitação em Bases do diagnóstico microscópico da malária é composto por dois módulos, que servem como uma estrutura para que os instrutores montem o curso. Ele fornece as informações mínimas necessárias para capacitar alunos em diagnóstico microscópico da malária pelo m...todo de Giemsa. O volume destina-se principalmente a pessoas com escolaridade relativamente baixa no momento do início do curso; os instrutores podem ajustar o curso para participantes com níveis mais altos de escolaridade. Técnicos atualmente responsáveis pelo diagnóstico microscópico da malária também se beneficiarão da leitura do Guia do aluno.
