Both are quick to perform, have a low cost and allow observing the presence, quantifying and analyzing the morphological characteristics of microfilariae. Knowing the morphological viability of fixed microfilariae is of practical importance, as it allows the transport of samples to a laboratory, facilitates epidemiological studies , and allows the storage of samples for didactic.

- - Aelurostrongylosis, a respiratory disease in cats caused by the parasite Aelurostrongylus abstrusus, varies in severity from mild to severe symptoms and is found globally but is often underestimated in terms of its impact.
- - Research on this parasite in Brazil is limited, particularly in the southern regions, prompting a study conducted in Vilhena, Rondônia, from April 2020 to February 2021.
- - The study analyzed fecal samples from 101 cats using specific tests, finding only 2 (1.98%) positive cases for A. abstrusus, with no other lungworms detected, leading to discussions on its clinical and epidemiological significance.
Background: Despite advances in the control of anxiety and fear, dental treatment (DT) continues to be a stressful event, especially during pregnancy. There are several instruments to measure anxiety and fear about DT (AFDT). However, few are validated for use in Brazil.

Trypanosoma cruzi is a widespread protozoan in Latin America causing Chagas disease in humans and able to infect several other mammal species. The objective of this study was to investigate the T. cruzi infection in triatomine fauna as well as in dogs from distinct areas of Acre, western Brazilian Amazonia, which recently reported acute cases of human CD as well as an area that have not notify this disease recently.
