Heteropriapulus Kritsky, 2007 (Monogenea: Dactylogyridae), which originally included only two species from the gills of loricariid catfishes, is reviewed and six newly described loricariids in Paraná River basin Brazil are added. Diagnosis genus amended a key to identification provided. anchoradiatus n. sp. Pterygoplichthys ambrosettii (Holmberg) (Hypostominae) differs its congeners by having long sclerotized vagina, ventral anchors with short shaft conspicuous superficial root, robust...
Parasitological studies on helminths of amphibians in South America have increased the past few years. Here, we present a list with summarized data published American from 1925 to 2012, including helminth parasites, host species, and geographic records. We found 194 reports parasitizing 185 amphibian species eleven countries: Argentina, Brazil, Chile, Colombia, Equador, French Guyana, Paraguay, Peru, Uruguay Venezuela. Helminth biodiversity includes 278 parasite groups Acanthocephala,...
A comprehensive and up to date summary of the literature on helminth parasites lizards amphisbaenians from South America is herein presented. One-hundred eighteen lizard species twelve countries were reported in harboring a total 155 species, being none acanthocephalans, 15 cestodes, 20 trematodes 111 nematodes. Of these, one record was Chile French Guiana, three Colombia, Uruguay, eight Bolivia, nine Surinam, 13 Paraguay, 12 Venezuela, 27 Ecuador, 17 Argentina, 39 Peru 103 Brazil. The...
There is an increasing interest in unveiling the dynamics of parasite infection. Understanding interaction patterns, and determinants host-parasite association contributes to filling knowledge gaps both community disease ecology. Despite being targeted as a relevant group for conservation efforts, amphibians their parasites broad scales are poorly understood. Here we describe biodiversity South American amphibians, testing influence host body size geographic range helminth species richness...
There are currently 760 reptile species known in Brazil, from which about 70 amphisbaenians with 25 recorded the Brazilian northeast (Vanzolini 2002; Gomes & Maciel 2012; Costa Bérnils, 2014; Roberto et al., 2014). Leposternon polystegum Duméril, is a widespread distributed Amazon, Atlantic Forest, Cerrado, and Caatinga biomes (Porto 2000; Ribeiro 2011). The diet composed mainly by ants, termites, coleopteran larvae (Barros-Filho Valverde, 1996; 2009).
Abstract Brazil is a megadiverse country and participant of fundamental environmental agreements for biodiversity conservation. However, the internal politics cultures that affect negatively ecological integrity in Brazilian freshwater need to be improved on condition sustainable management. Scientific community, government stakeholders are constant conflicts goals. Meanwhile, current model aquaculture shows problems impact due lack appropriated planning legislation aquatic biota. The...
A new species of the copepod genus Pseudovaigamus Amado, Ho & Rocha, 1984 is described herein based on parasitic adult females found attached to gills freshwater teleost Pimelodus maculatus Lacepède, 1803, sampled in two tributaries (Veados and Paranapananema Rivers) Jurumirim Reservoir, Upper Paranapanema River, São Paulo State, Brazil. The was identified as an undescribed because it shares with type-species, spinicephalus (Thatcher Robertson, 1984), combination first leg 2-segmented...
Urocleidoides spp. are reported from the gills of 20 specimens Parodon nasus (standard length 8.512 cm), Indiana stream, Tiet River, Upper Paran River basin, municipality Botucatu, So Paulo State, Brazil. Urocleoidoides tenuis and two new species were found. indianensis n. sp. differs its congeners mainly by morphology vaginal sclerite that is robust, sickle-shaped, forked at distal end; bulbous-shaped accessory piece male copulatory complex. parodoni resembles U. presenting organ with...
A new nematode species of the Diplotriaenidae is described from Neotropical region. The was found infecting body cavity snake Xenodon merremii (Wagler in Spix) collected municipality Barbalha, Ceará State, Northeastern Brazil. Hastospiculum nordestinum n. sp. differs congeners by combining following characters: caudal end ornamented with lateral alae not surrounding tail and connected, supported eight pairs pedunculated papillae (three precloacal, one paracloacal, four postcloacal pairs)...
Numerous pseudoplasmodia containing myxospores belonging to the genus Cystodiscus were found in gallbladder of Elachistocleis cesarii from Mato Grosso State, Brazil. Herein, we describe elachistocleis sp. nov., using morphological and small subunit ribosomal DNA sequences. The mature ellipsoid ovoid, measuring average 10.6 (9.8–11.2) μm length 6.2 (5.6–6.6) width. Polar capsules pyriform equal size 3.6 (2.8–4.3) 2.6 (2.2–3.1) filaments had 2–4 coils. 3–5 transverse ridges. phylogenetic...
The richness of metazoan endoparasites associated with 25 anuran species from a transitional area between Cerrado and Atlantic Rain Forest Brazil is here presented. We present discuss the type-host localities, current taxonomic status, remarks on morphological features, biological cycle, new records these parasites. Nine hundred seventy-eight anurans four families (Bufonidae, Hylidae, Microhylidae, Leptodactylidae) were collected during expeditions in private forested Northwest São Paulo...
Aplectana longa n. sp. (Ascaridida: Cosmocercidae) from the small intestine of Gastrotheca microdiscus (Amphibia: Hemiphractidae) is described and illustrated. The new species characterized by combination a unique set morphological characters: 1) Large body size in both sexes; 2) Lateral alae absent; 3) Gubernaculum present, small, thin, weakly sclerotized, pointed at distal end curved proximally end, with punctiform papilla-like dilation, 4) Caudal papillae arrangement (9+1:0:6)....
A new nematode species, Rhabdochona (Rhabdochona) fuscovaria sp. n. (Rhabdochonidae), is described based on specimens collected from the stomach of snouted treefrog Scinax fuscovarius (Hylidae) in So Sebastio do Paraso farm, municipality Boa Esperan Sul, southeastern Brazil. This species characterized by deirids small, simple and stylet shaped, prostom funnel-shaped with 14 teeth, conspicuous left spicule (585.7 m), distal tip slightly widened, moderately dilated, right (132.9 boat-shaped,...
An increasing demand for fish products has led to an intensive aquaculture production in Brazil, and cultivation of constituted 860 × 103 tons 2022, contributing the 87% total consumption. Nile tilapia constitutes almost half production, most farms use floating net cages. One major constraints is off-flavors. Release nutrients by leads deterioration water quality stimulates growth microorganisms, also including off-flavor producing species. The objective this study was determine levels taste...
Paracoccidioides brasiliensis infections have been little studied in wild and/or domestic animals, which may represent an important indicator of the presence pathogen nature. Road-killed animals used for surveillance vectors zoonotic pathogens and offer new opportunities eco-epidemiological studies paracoccidiodomycosis (PCM). The P. infection was evaluated by Nested-PCR tissue samples collected from 19 road-killed animals; 3 Cavia aperea (guinea pig), 5 Cerdocyon thous (crab-eating-fox), 1...
For this study, we performed a parasitological analysis of cage-cultured Nile tilapia (Oreochromis niloticus) from the Água Vermelha Reservoir, Southeastern Brazil, and verified relationships with limnological data, seasonality, fish growth phase. From March 2010 to 2011, sixty-three specimens O. niloticusin three phases (i.e., initial, intermediate, final) were collected. All infested at least one ectoparasite species (prevalence = 100%). Five protozoans (Trichodina compacta, Trichodina...
Abstract During an ecological study with a near-endangered anuran in Brazil, the Schmidt’s Spinythumb frog, Crossodactylus schmidti Gallardo, 1961, we were given chance to analyze gastrointestinal tract of few individuals for parasites. In this paper, describe new species allocreadiid trematode genus Creptotrema Travassos, Artigas & Pereira, 1928, which possesses unique trait among allocreadiids (i.e., bivalve shell-like muscular structure at opening ventral sucker); represents fourth...
Abstract: An l ‐amino acid oxidase (BjarLAAO‐I) from Bothrops jararaca snake venom was highly purified using a stepwise sequential chromatography on Sephadex G‐75, Benzamidine Sepharose and Phenyl Sepharose. Purified BjarLAAO‐I showed molecular weight around 60,000 under reducing conditions about 125,000 in the native form, when analysed by sodium dodecyl sulfate‐polyacrylamide gel electrophoresis filtration, respectively. is homodimeric acidic glycoprotein, pI ~5.0, N‐terminal sequence...
