“…Setaria labiatopapillosa ( syns., Setaria cervi ) (Figure-4) prevalence in Aceh cattle slaughtered in a Banda Aceh slaughterhouse is 4%. This result is much lower compared to research carried out Bino and D’Souza [21] which found that out of the 500 cattle screened, 187 (37.4%) were found harboring Setaria worms in the peritoneal cavity. Three species of Setaria, namely, Setaria digitata, S. cervi, and S. labiatopapillosa were observed in the Bino study.…”

Aim: The objective of this research was to identify the parasite species found in the gastrointestinal tract and pancreas of Aceh cattle slaughtered in a Banda Aceh slaughterhouse using lactophenol and semichon carmine staining. Materials and Methods: Each sample out of 50 samples of gastrointestinal tract and pancreas from Aceh cattle slaughtered in a Banda Aceh slaughterhouse was separated by organ. Each organ was examined for the presence of worm. Then, the parasitic worms found were subsequently collected and separated based on class and species, followed by staining using lactophenol and semichon carmine. The worms were then identified and their prevalence was determined. Results: The results showed that three species of parasites were successfully identified, all belonging to the nematode class, namely, Oesophagostomum radiatum, Oesophagostomum columbianum, and Setaria labiatopapillosa with the prevalence of 12%, 10%, and 6%, respectively. In addition, there was one species of parasite from the trematode class, namely, Eurytrema pancreaticum with prevalence of 0.4%. Conclusion: The nematode class worms, such as O. radiatum, O. columbianum, and S. labiatopapillosa, can be stained by lactophenol, while the trematode class worm such as E. pancreaticum can be stained by semichon's carmine.

“…Although S. cervi became a model species for anti-filarial drugs and treatment methods decades ago (Singhal et al ., 1969), not much is known about its presence in the wild. Known definitive hosts of S. cervi are: the moose ( Alces alces ), the red deer ( Cervus elaphus ), the sika deer ( Cervus nippon ), the Asian wapiti ( Cervus elaphus sibirica ), the muntjac ( Cervus muntjac) , the chital ( Axis axis ), the fallow deer ( Dama dama ) (Yeh, 1959; Wang et al ., 1990; Anderson, 2000) but also cattle; Bos taurus (Baqui and Ansari, 1976; Sundar and D'Souza, 2015) and Bubalus bubalus (Almeida et al ., 1991). Infection with S. cervi can lead to pathological changes in the central nervous system in definitive hosts (Blažek and Dykova, 1968; Wang et al ., 1990).…”

New findings of Setaria tundra and Setaria cervi in the red deer (Cervus elaphus) in Poland

Our study aimed at examining the phylogenetic position of the newly-found Setaria nematodes obtained from the red deer (Cervus elaphus) based on sequences of the mitochondrial cytochrome c oxidase subunit 1 (COX-1). Alignment and phylogenetic analyses, as well as SEM microscopic analysis, revealed the presence of two Setaria species: S. cervi and S. tundra. Setaria tundra was noted in only one individual, a calf of the red deer, while S. cervi was observed in three stages, two hinds and one calf of the red deer. According to our knowledge, it is the first case of S. cervi in the red deer in Poland confirmed in molecular studies and also the first case of S. tundra infection in the red deer.

Background The commensal microbiota of mosquitoes impacts their development, immunity, and competency, and could provide a target for alternative entomological control approaches. However, despite the importance of the mosquito/microbiota interactions, little is known about the relative contribution of genetic and non-genetic factors in shaping the bacterial communities of mosquitoes. Methods We used a high-throughput sequencing based assay to characterize the bacterial composition and diversity of 665 individual field-caught mosquitoes, as well as their species, genotype at an insecticide resistance locus, blood meal composition, and the eukaryotic parasites and viruses they carry. We then used these data to rigorously estimate the individual effect of each parameter on the bacterial diversity as well as their relative contribution to the microbial composition. Results Overall, multivariate analyses did not reveal any significant contribution of the mosquito species, insecticide resistance or blood meal to the bacterial composition of the mosquitoes surveyed. Infection with parasites and viruses only contributed very marginally and the main driver of the bacterial diversity was the location where each mosquito was collected which explained roughly 20% of the variance observed. Conclusions This analysis shows that, when confounding factors are taken into account, the sites where the mosquitoes are collected is the main driver of the bacterial diversity of wild-caught mosquitoes, although further studies will be needed to determine how the specific components of the local environment affecting the bacterial composition.
