  abstract = {<p><strong>BACKGROUND</strong></p>

<p>Trypanosomatid infections such as Chagas disease (CD) and leishmaniasis remain major public-health concerns. Brazil has a long tradition in this field, yet a consolidated, country-level view of outputs, impact and collaboration patterns is useful to guide scientific policy.</p>

<p><br />
<strong>OBJECTIVES</strong>&nbsp;</p>

<p>To characterise Brazilian scientific production on&nbsp;<em>Trypanosoma cruzi</em>,&nbsp;<em>Leishmania</em>&nbsp;and&nbsp;<em>Trypanosoma brucei</em>&nbsp;(2010-2021), describing temporal trends, regional contributions, collaboration networks and journal impact.</p>

<p><br />
<strong>METHODS</strong>&nbsp;</p>

<p>We performed a bibliometric analysis of PubMed records retrieved with Medical Subject Headings (MeSH) for each pathogen/disease pair, covering publications from 1 January 2010 to 31 December 2021 (search date: 21 July 2022). Data items included article type, year, journal, author affiliations (countries/institutions) and, for Brazil, the geographical region of the corresponding author. Descriptive statistics and visualisations were generated in R.<br />
&nbsp;</p>

<p><strong>FINDINGS</strong>&nbsp;</p>

<p>From 21,713 records, 6,478 were affiliated to Brazil. Brazil contributed a substantial share of the global literature, particularly for&nbsp;<em>T. cruzi</em>&nbsp;(≈40%) and<em>&nbsp;Leishmania</em>&nbsp;(≈30%). Within Brazil, output increased over time with growing participation from the north and northeast, alongside expanding inter-institutional and international collaborations. Most publications appeared in higher-impact journals (Q1/Q2), with recent gains in Q1 outputs in historically under-represented regions. Original research predominated over reviews across the period.</p>

<p><br />
<strong>MAIN CONCLUSIONS</strong>&nbsp;</p>

<p>Brazilian trypanosomatid research shows sustained growth, increasing regional dispersion and rising international engagement, with a strong presence in high-impact journals. Continued support for collaborative networks and equitable funding across regions could further enhance national and global impact.</p>
