AI Article Synopsis

  • A study was conducted to estimate the prevalence of a rickettsial pathogen responsible for spotted fever in ticks across various regions in the Americas, as no prior systematic reviews had been done.
  • Data was collected using PRISMA guidelines from four databases, and a random-effects model was employed to analyze the pooled prevalence and its variability.
  • Findings revealed that Colombia had the highest prevalence of the pathogen in ticks (17.00%), with Mexico (9.89%), Panama (2.76%), Brazil (2.03%), and the United States (0.50%) following; the most commonly infected tick species were Rhipicephalus (6.23%) and Amblyomma (4.36%).

Article Abstract

is a pathogen that is known to cause spotted fever, a zoonosis that is endemic in several regions of the Americas. However, no systematic review and meta-analysis has been conducted to estimate the prevalence of this rickettsial disease in the Americas. Therefore, the objective of this study was to estimate the prevalence of in ticks in the Americas. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed and data were retrieved from four electronic databases: MEDLINE/PubMed, SciELO, ScienceDirect, and Directory of Open Access Journals. The pooled prevalence and heterogeneity were determined using a random-effects model and using Cochran's test and index, respectively. Publication bias was assessed using a funnel plot and Egger's method. The pooled prevalence of in ticks was highest in Colombia (17.00%; confidence interval [95% CI]: 7.01-30.24), followed by Mexico (9.89%; 95% CI: 2.03-22.74), Panama (2.76%; 95% CI: 0.45-6.93), Brazil (2.03%; 95% CI: 0.66-4.14), and the United States (0.50%; 95% CI: 0.15-1.05). The tick species most frequently infected by were sensu lato (6.23%; 95% CI: 2.79-10.92) and (4.36%; 95% CI: 0.25-13.14). It can be suggested that studies aiming to identify the potential vectors of should be conducted more intensively to better understand the epidemiology of spotted fever in the Americas.
