Occurrence of endo and hemoparasites in Sporophila caerulescens captured in the eastern region of the state of Acre, Brazil

Abstract

Wild animals are hosts and reservoirs to many infectious agents, often unknown to the Scientific Community, which leads to serious health implications for natural and domestic environments. We conducted this research with the objective of diagnosing the occurrence of parasites of medical and veterinary interest in “coleirinhos” captured in the eastern region of the state of Acre, Brazil. We captured the specimens in August and September of 2017 using ornithological nets at the margins of Caeté river. We visually inspected the birds to evaluate the ectoparasites. Subsequently, we collected blood through a brachial vein puncture and rested the individuals in a cloth bag for 30 minutes to collect feces, after which we released them. Results of the visual inspection to detect and identify the ectoparasites were negative. Blood samples revealed the protozoan Haemoproteus sp., and the feces revealed cysts of Entamoeba histolytica and E. coli, oocysts of coccidia and eggs of Davaineidae. Coccidia was the most prevalent (69.2%) and abundant (34.15%) parasite reported. Parasites diagnosed in this study can promote the emergence of secondary infections in S. caerulescens individuals or other animals that are contaminated with these etiological agents, since, when migrating through different biomes of South America, other animal species can come into contact with these agents.

Diversity, geographical distribution, and prevalence of Entamoeba spp. in Brazil: a systematic review and meta-analysis

“…Our systematic literature search yielded 1694 manuscripts using the established search strategies. As per the eligibility criteria (after exclusion of duplicate texts and articles related to other topics and exclusion of text based on review criteria or owing to method quality), 182 studies were selected for analysis ( Table 1 ) [ 2 – 4 , 6 , 7 , 9 – 25 , 27 – 37 , 39 , 40 , 42 – 45 , 47 – 56 , 58 , 60 – 63 , 65 – 69 , 71 , 72 , 74 , 75 , 77 – 83 , 85 – 93 , 95 – 104 , 106 – 109 , 111 , 114 – 123 , 125 – 130 , 132 , 135 , 136 , 138 – 140 , 142 – 146 , 148 – 150 , 153 – 164 , 167 , 169 – 173 , 175 – 192 , 194 – 204 , 207 – 210 , 212 – 215 , 217 – 219 ]. Of these studies, 166 evaluated the prevalence of Entamoeba spp.…”

First report of Davaneidae and Strongylida parasitizing Ramphocelus carbo (Aves: Passeriformes: Thraupidae) in the southwest of the Brazilian Amazon region

“…were found in a species of Thaupidae (Tangara episcopus). Souza et al (2019) found samples of Sporophila caerulescens (Thaupidae) parasitized by oocysts Coccidia, cysts of E. coli and E. histolytica and eggs of Davaineidae. These data suggest a possible source of infection among bird species in the region.…”

“…Infected individuals of the species R. carbo can generate numerous health problems affecting a diversity of birds and, most probably, other organisms related to them (Costa et al, 2010;Berto et al, , 2009Brito et al, 2017;Freitas et al, 2002;Marietto-Goncalves et al, 2009;Souza et al, 2019). New molecular research techniques need to be implemented so that such findings can become increasingly reliable and authoritative.…”
