[Ab] Resumo:A survey was performed to investigate the infection status of zoonotic trematode (ZT) metacercariae in fish from a local market in Yangon City, Myanmar. A total of 264 fish (12 species) were collected through 4 times from December 2013 to June 2015. All collected fish were transferred to our laboratory on ice and examined by the artificial digestion method. More than 7 species of ZT metacercariae, i.e., Haplorchis taichui, H. pumilio, H. yokogawai, Centrocestus spp., Stellantchasmus falcatus, Pygidiopsis cambodiensis, and Procerovum sp. were detected. Metacercariae of H. taichui were collected in 58 (42.3%) out of 137 fish (5 species), and their average density was 42.9 per fish infected. Metacercariae of H. pumilio were detected in 96 (49.0%) out of 196 fish (9 species), and their average density was 23.6 per fish infected. H. yokogawai metacercariae were found in 40 (50.0%) out of 80 fish (5 species), and Centrocestus spp. metacercariae in 91 (50.8%) out of 179 fish (8 species), and their densities were 306 and 25.8 per fish infected, respectively. Metacercariae of S. falcatus and P. cambodiensis were detected only in mullets, Chelon macrolepis. A total of 280 Procerovum sp. metacercariae were found in 6 out of 12 climbing perch, Anabas testudineus. Morphological characteristics of adult flukes recovered from experimental animals were described. It has been first confirmed that fish from Yangon, Myanmar are commonly infected with various species of ZT metacercariae.

[Ab] Resumo:Metorchis orientalis is a neglected zoonotic parasite, living in the gallbladder and bile duct of poultry and some mammals as well as humans. In spite of its economic and medical importance, the information known about the transcriptome and genome of M. orientalis is limited. In this study, we performed de novo sequencing, transcriptome assembly and functional annotations of the adult M. orientalis, obtained about 77.4 million high-quality clean reads, among which the length of the transcript contigs ranged from 100 to 11,249 nt with mean length of 373 nt and N50 length of 919 nt. We then assembled 31,943 unigenes, of which 20,009 (62.6%) were annotated by BLASTn and BLASTx searches against the available database. Among these unigenes, 19,795 (62.0%), 3407 (10.7%), 10,620 (33.2%) of them had significant similarity in the NR, NT and Swiss-Prot databases, respectively; 5744 (18.0%) and 4678 (14.6%) unigenes were assigned to GO and COG, respectively; and 9099 (28.5%) unigenes were identified and mapped onto 256 pathways in the KEGG Pathway database. Furthermore, we found that 98 (1.08%) unigenes were related to bile secretion and 5 (0.05%) to primary bile acid biosynthesis pathways category. The characterization of these transcriptomic data has implications for the better understanding of the biology of M. orientalis, and will facilitate the development of intervention agents for this and other pathogenic flukes of human and animal health significance.

[Ti] Título:Assessment of in vitro killing assays for detecting praziquantel-induced death in Posthodiplostomum minimum metacercariae.

[Ab] Resumo:Control of parasitic infections may be achieved by eliminating developmental stages present within intermediate hosts, thereby disrupting the parasite life cycle. For several trematodes relevant to human and veterinary medicine, this involves targeting the metacercarial stage found in fish intermediate hosts. Treatment of fish with praziquantel is one potential approach for targeting the metacercaria stage. To date, studies investigating praziquantel-induced metacercarial death in fish rely on counting parasites and visually assessing morphology or movement. In this study, we investigate quantitative methods for detecting praziquantel-induced death using a Posthodiplostomum minimum model. Our results revealed that propidium iodide staining accurately identified praziquantel-induced death and the level of staining was proportional to the concentration of praziquantel. In contrast, detection of ATP, resazurin metabolism, and trypan blue staining were poor indicators of metacercarial death. The propidium iodide method offers an advantage over simple visualization of parasite movement and could be used to determine EC values relevant for comparison of praziquantel sensitivity or resistance.

[Ti] Título:Gastric lesions in dolphins stranded along the Eastern Adriatic coast.

[Ab] Resumo:Stranded cetaceans are often found with gastric lesions associated with the presence of parasites; most frequently, nematodes of the genus Anisakis and the heterophyd digenean trematode Pholeter gastrophilus. In this study, we present histopathology mainly (but not exclusively) related to these 2 parasite species. Macroscopically, lesions associated with the presence of Anisakis spp. were characterised by the presence of ulcers within the gastric mucosa, while the digenean P. gastrophilus was found within large submucosal fibrotic nodules in the gastric wall. Anisakis-induced alterations included severe ulcerative gastritis with mixed inflammatory infiltrate often associated with colonies of bacteria, and mild to moderate granulomatous gastritis with eosinophilic infiltrate. P. gastrophilus-associated lesions were characterised by fibrogranulomatous gastritis with mixed inflammatory infiltrate. Additionally, immunohistochemical (IHC) analysis of P. gastrophilus lesions was consistent with the histopathologic findings, revealing inflammation-mediated stimulation. IHC-positive localisation of CD3+, iNOS+ and caspase-3+ cells suggests intensive accumulation of cytotoxic T-cells, proinflammatory cytokines and execution-phase of cell apoptosis at the parasitized area. In contrast, mechanical damage, rather than visible inflammatory response could be observed at the site of attachment of Braunina cordiformis recorded in 4 animals. Lesions not associated with the presence of parasites were mostly characterised by focal loss of superficial epithelial cells and accumulation of brown hemosiderin-like pigment or fibrous gastritis with lymphoplasmacytic infiltrate. In light of these results, we argue that observed 'tolerant' host-parasite interactions that led toward gastric lesions do not represent the cause of death and stranding of cetaceans included in this study.

[Ti] Título:Dawestrema cycloancistrium (Monogenea) from the head pores of arapaimas.

[Ab] Resumo:Arapaima gigas is one of the main cultured fish species in South America, and monogenean parasites of this species cause large economic losses to fish farmers. During surveys of the parasites of cultured arapaimas from Mexiana Island in the Amazon River Delta, Rio Branco, in northwestern Brazilian Amazonia, and Yurimaguas, Peru, the monogenean Dawestrema cycloancistrium was found in the gills of A. gigas as well as in previously unreported sites, i.e. the head pores and chambers. The aim of this study was to investigate the transmission route of this parasite and its geographical distribution as well as to describe its morphology as observed by light and confocal imaging. Phalloidin labeling confirmed the presence of 2 prostatic reservoirs and showed muscular branches of fibers supporting haptoral sclerites. In arapaimas, the head connects to the gill chambers via 2 perforated scales located at the dorsolateral sides of the distal part of the head. The scales connect to thin channels and chambers situated in the proximal part of the head. These chambers are filled with cephalic mucus, which flows out to the environment through terminal pores. Adults and egg masses of monogeneans were found on the gills and inside the head pores and cavities of fish along with cephalic mucus. This indicates a specialized method of parasite transmission from adult fish to fingerlings during parental care (holding offspring in the mouth) or via head secretions, providing evidence of a new adapted mechanism of dispersion.

[Ti] Título:Brachylaimiasis: Brachylaima spp. (Digenea: Brachylaimidae) Metacercariae Parasitizing the Edible Snail Cornu aspersum (Helicidae) in Spanish Public Marketplaces and Health-Associated Risk Factors.

[Ab] Resumo:The edible land snail Cornu aspersum (Pulmonata: Stylommatophora) acts as a second intermediate host in the terrestrial life cycle of Brachylaima spp. trematodes, harboring unencysted metacercariae in its kidney. The ingestion of undercooked infected snails by humans may allow metacercariae to potentially develop to adult stage in the intestine, causing brachylaimiasis, as already seen in Australia. The prevalence and dynamics of C. aspersum parasitization by Brachylaima spp. metacercariae in specimens intended for human consumption in Spanish marketplaces were studied. In total, 3,710 C. aspersum specimens were analyzed over 5 yr, which were obtained from public marketplaces in the Spanish cities of Barcelona, Bilbao, Madrid, Tudela, Valencia, and Zaragoza. The overall prevalence was 41.97% (95% CI: 40.38-45.56%). The Tudela marketplace had the highest values for both the seasonal prevalence and abundance in all studies during autumn (93.57% and 3.09, respectively). This market also gave the highest individual metacercarial burden recorded, 212 metacercariae in a single specimen. Overall, the highest prevalence of Brachylaima spp. occurred in autumn (58.65%) and the lowest in winter (22.64%). There was a seasonal effect on prevalence, which increased from summer to autumn and then decreased in winter. In total, 96 experimental Brachylaima adults were obtained from the metacercariae parasitizing the analyzed snails. These were identified through morphometric tools (principal component analysis) as Brachylaima mascomai (56 in Barcelona, 1 in Bilbao, 7 in Tudela, and 3 in Valencia), and Brachylaima llobregatensis (17 in Barcelona, 8 in Bilbao, 1 in Valencia, and 3 in Zaragoza). Logistic regression modeling, conducted to predict the probability of purchasing parasitized snails using city and season as predictors showed a correct prediction overall of 79.0%, with a significant (p = 0.001) risk effect in the Barcelona-autumn interaction (2.551-38.442), a significant (p = 0.049) protection effect in the Tudela-spring interaction (0.076-0.997), a significant (p < 0.001) risk effect in the Tudela-autumn interaction (4.330-78.584), and a significant (p = 0.014) protection effect in the Valencia-spring interaction (0.033-0.687). The high overall prevalence of Brachylaima spp. metacercariae should be a matter of concern for public health authorities, mainly in countries where C. aspersum is consumed.

[Ab] Resumo:The diversity and taxonomy of diplostomids infecting freshwater fishes of the Indian region are predominantly poorly known. Yet compared to other trematodes, identification and discrimination of diplostomid metacercaria are difficult using morphology and site of infection. The present study provides the first molecular study of a Tylodelphys sp. from India. Specimens of Tylodelphys were collected from the vitreous humor of the eyes and from the brains of siluriform fish, Mystus tengara (Siluriformes: Bagridae) from Hastinapur, Meerut (U.P.), India. Taxonomic studies were performed on the basis of morphological, morphometrical, and molecular analysis. The dissimilarities in morphological and sites of infection between 2 forms of Tylodelphys, designated as Tylodelphys sp. 1 and Tylodelphys sp. 2, suggested that the forms were different species but, after performing molecular analysis, we conclude that despite morphological differences both morphotypes are conspecific.

[Ti] Título:Spatial and Temporal Changes in the Distribution of Blood Fluke Infection in Nicolea gracilibranchis (Polychaeta: Terebellidae), the Intermediate Host for Cardicola orientalis (Digenea: Aporocotylidae), at a Tuna Farming Site in Japan.

[Ab] Resumo:Fish blood flukes of the genus Cardicola (Digenea: Aporocotylidae) are important pathogens in tuna aquaculture. Recent advances in marine blood fluke research have led to the elucidation of the lifecycles of 3 Cardicola spp. infecting tuna; all 3 flukes utilize terebellid polychaetes as the intermediate host. In our survey, we obtained large numbers of Nicolea gracilibranchis infected by larval Cardicola orientalis at our tuna farming site. To determine the spatial and temporal changes in the distribution of N. gracilibranchis surrounding tuna culture cages and their infection by C. orientalis, we conducted monthly sampling for a period of 1 yr. Terebellids were most abundant on the floats and ropes of culture cages, but a significantly higher proportion of infected N. gracilibranchis was detected on ropes, particularly up to 4 m in depth. Cardicola orientalis infection in N. gracilibranchis was clearly seasonal, with a higher infection rate between April and July. Our findings indicate that the infected terebellids inhabit specific microhabitats, and both abiotic and biotic factors likely influence blood fluke infection in the intermediate terebellid host. This information is important to better understand the general biology of marine aporocotylids and may be useful to develop a control strategy for blood fluke infection in tuna aquaculture.

[Ab] Resumo:Gulf Coast spiny softshell turtles, Apalone spinifera aspera (Agassiz, 1857) (Testudines: Trionychidae) from Canoe Lake (33°47'56.16″N, 86°29'25.02″W; Springville, Alabama) and Round Lake (32°41'50.91″N, 87°14'30.39″W; Perry Lakes State Park, Marion, Alabama), were infected by V. robustum Stunkard, 1928 , Vasotrema longitestis Byrd, 1939 , and Vasotrema rileyae n. sp. The new species differs from its congeners by having papillate suckers, a short testis, an ovary dextral to the oviduct, and a pre-ovarian genital pore that is lateral to the ventral sucker. We studied the newly collected specimens and museum specimens of all congeners to revise the diagnosis of Vasotrema Stunkard, 1926 and redescribe and provide an updated dichotomous key to all species of the genus.
