Projecting the potential distribution of <i>Rickettsia japonica</i> in China and Asian adjacent regions under climate change using the Maxent model.

ABSTRACT:

Objective

To determine the current and future suitable areas of Rickettsia japonica, and to provide a reference for preventing its outbreak and spread.

Methods

Based on the geographic distribution of R. japonica and Haemaphysalis longicornis overlapping data points and information on 56 climatic factors, we utilized the Maxent model to estimate suitable areas for R. japonica in Asian adjacent Regions and China. Model parameter adjustments and the construction of receiver operating characteristic curves were conducted using R 4.3.0 software.

Results

Average precipitation in June (prec6, 28.2%), Temperature Seasonality (bio4, 9.8%) and the minimum temperature in August (tmin8, 9.2%) contributed most to the distribution of R. japonica.
