Human bertiellosis in Goiás, Brazil: a case report on human infection by Bertiella sp. (Cestoda: Anoplocephalidae)

Abstract

SUMMARYThe authors report on a new case of human Bertiellosis in a 2-year old female patient who was born in Goiânia-Goiás (Brazil) and has had history of permanent dwelling in an area frequently visited by simians in Mato Grosso (Brazil). At the time of diagnosis the patient showed inappetence, abdominal pain, and loss of weight. Eggs and proglottids were found in her stool and were identified as Bertiella sp. The objective of this report is to register the third case of human Bertiellosis in Brazil, characterizing one more case of helminthic zoonosis.

Human Bertielliasis in Amazonia: Case Report and Challenging Diagnosis

“…In South America, only seven cases of human bertielliasis have been reported, and all have been attributed to B. mucronata [5]. Three of these cases were recorded in Brazil, although the most recent report identified the parasite at only the genus level [11]. Until now, no human bertielliasis has been reported in the Amazon region and the risk of infection is not widely known, although B. mucronata has recently been observed in Peruvian titi monkeys [12].…”

Bertiella studeri Infection in Children, Sri Lanka

“…According to the available demographic data, most of the patients resided in Central Province, Sri Lanka; the most likely reason that they comprised most patients is the Bertiella tapeworm reservoir hosts, particularly Ceylon torque monkey (Macaca sinica) and gray langur (Presbytis entellus), that inhabit this region (12,13). Over time, these monkey populations have lost their habitats due to deforestation and rapid urbanization in Sri Lanka; they are now regular visitors in suburban and urban areas scavenging for food near human settlements, which has increased human exposure to B. studeri infection (14,15). Unavailability of molecular data for B. studeri 28S, COX1, and NAD1 markers in GenBank was a constraint that we encountered during phylogenetic analysis.…”

FIRST CASE OF HUMAN INFECTION BY Bertiella studeri (Blanchard, 1891) Stunkard,1940 (Cestoda; Anoplocephalidae) IN BRAZIL

“…The third human infection by Bertiella sp. was diagnosed in a two-year-old infant from Goiania, Goias State 16 . SILVA et al .…”

“…in humans have been reported around the world 21 . In Brazil, up to now, only four human cases were detected based on morphological and morphometric egg analysis 3 , 16 , 17 , 19 .…”
