Genetic and morphologic characterization of diaschistorchis pandus (digenea: pronocephalidae) trematodes extracted from hawksbill turtles, eretmochelys imbricata (testudines: cheloniidae), in grenada, west indies
J Parasitol. 2021 Mar 1;107(2):267-274. doi: 10.1645/20-54.ABSTRACTThe hawksbill turtle Eretmochelys imbricata is a critically endangered species with a worldwide distribution. Limited information is available about the naturally occurring intestinal parasites of this species and what impact these parasites may have on the health of the hawksbill turtle. Diaschistorchis pandus was identified postmortem in 5 hawksbill turtles from Grenada, West Indies, using morphologic characterization. Sanger sequencing was performed for conserved ribosomal regions (5.8S, ITS2, 28S) and the mitochondrial cytochrome c oxidase subunit 1 gen...

A misidentification crisis plagues specimen-based research: a case for guidelines with a recent example (ali et al., 2020)

A New Species of Cosmocercoides (Ascaridida: Cosmocercidae) Parasitic in Tree Frogs from Southern Amazonia
J Parasitol. 2021 Mar 1;107(2):239-245. doi: 10.1645/20-78.ABSTRACTCosmocercoides meridionalis n. sp. is described from the large and small intestines of 5 species of tree frogs belonging to the families Hylidae and Phyllomedusidae collected from 2 localities in Southern Amazonia. The new species is allocated to the genus Cosmocercoides Wilkie, 1930, due to the presence of papillae in rosettes, which are complex caudal papillae surrounded by punctuations. Cosmocercoides meridionalis n. sp. differs from its congeners by a combination of the following characters: the absence of the gubernaculum, the total length of the femal...

Multilocus Genotyping of Sympatric Hepatozoon Species Infecting the Blood of Ontario Ranid Frogs Reinforces Species Differentiation and Identifies an Unnamed Hepatozoon Species

Although gamonts of both species are morphometrically similar, the cytopathological changes that 1 of these species, Hepatozoon clamatae, causes to host erythrocytes, manifested by nuclear fragmentation, was used historically to distinguish this parasite from Hepatozoon catesbianae.

Peroxisome-Proliferator Activator Receptor γ in Mouse Model with Meningoencephalitis Caused by Angiostrongylus cantonensis
In this study we investigated the role of PPARγ and related mechanisms in eosinophilic meningoencephalitis caused by the rat lungworm Angiostrongylus cantonensis. We observed increased protein NF-κB expression in mouse brain tissue using GW9662, which is the specific antagonist of PPARγ, in a mouse model of angiostrongyliasis. Then we investigated NF-κB-related downstream proteins, such as COX-2, NOSs, and IL-1β, with Western blot or enzyme-linked immunosorbent assay and found that the protein expression was upregulated. The results of gelatin zymography also showed that the MMP-9 activities we...

Peroxisome-Proliferator Activator Receptor γ in Mouse Model with Meningoencephalitis Caused by Angiostrongylus cantonensis
In this study we investigated the role of PPARγ and related mechanisms in eosinophilic meningoencephalitis caused by the rat lungworm Angiostrongylus cantonensis. We observed increased protein NF-κB expression in mouse brain tissue using GW9662, which is the specific antagonist of PPARγ, in a mouse model of angiostrongyliasis. Then we investigated NF-κB-related downstream proteins, such as COX-2, NOSs, and IL-1β, with Western blot or enzyme-linked immunosorbent assay and found that the protein expression was upregulated. The results of gelatin zymography also showed that the MMP-9 activities we...

Account and Utilization of Blood Lipid Profiles: Lipid Levels Predicted Hemosporidian Infection in Migrating Northern Saw-Whet Owls of Eastern North America
J Parasitol. 2021 Mar 1;107(2):147-154. doi: 10.1645/20-114.ABSTRACTNoting lipidomic changes following the parasitism of migrating birds, the metabolic needs of which are primarily fueled by lipids, can deepen our understanding of host-parasite interactions. We identified lipids of migrating Northern saw-whet owls (Aegolius acadicus) using collision-induced dissociation mass spectrometry, compared the lipidomic signatures of hemoparasite-infected and noninfected individuals, and performed cross-validation analyses to reveal associations between parasite infection and lipid levels. We found significantly lower levels of lip...

Early Detection of Trichinella spiralis DNA in Rat Feces Based on Tracing Phosphate Ions Generated During Loop-Mediated Isothermal Amplification
J Parasitol. 2021 Mar 1;107(2):141-146. doi: 10.1645/19-137.ABSTRACTEarly diagnosis of trichinellosis is still difficult because of the lack of specific symptoms and limited window for serological detection. Here we established an assay based on tracing phosphate ions generated during loop-mediated isothermal amplification (LAMP) to detect Trichinella spiralis DNA in rat feces during its early stage of infection. By targeting a 1.6-kb repetitive element of Tri. spiralis, the assay was able to detect Tri. spiralis DNA in the feces of all infected rats as early as 1 day postinfection (dpi). The positive detection lasted to 7...

Adults and fourth-stage larvae, all females, found in the feces, and the third-stage larvae excised from the uterus of the gravid females were described. By close observation of the molting worms, it was considered that the uterine third-stage larvae attain molting phase, and then are laid to become fourth-stage larvae. Nutrients required for la...

Comparative Immunological Response and Pathobiology of Mice Inoculated with Toxoplasma gondii Isolated from Different Hosts
J Parasitol. 2021 Mar 1;107(2):179-181. doi: 10.1645/20-107.ABSTRACTToxoplasma gondii is an obligate intracellular parasite that has a worldwide distribution and can infect almost all warm-blood animals. Serological tests are the main detection methods for T. gondii infection in animals and humans. Little is known of biological behavior, antibody responses, and virulence of T. gondii strains in mice from China. Here we document antibody responses, tissue cyst burden, and mouse virulence of T. gondii strains isolated from different hosts in China. All T. gondii strains formed tissue cysts in the brains of mice and positivel...

The new species is characterized by the medium-sized male worms (6.7-8.7 mm in length and 154-182 μm in width) relative to known members of the genus, 2 pointed spicules of unequal length (87-112 μm and 56-72 μm in length), and 10 pairs of caudal papillae. Female worms are larger than male worms (10.7-18.4 mm in length and 264-411 μm in width), with the vulva situated in the anterior part, and embryonated, el...

Epidemiological Significance of Toxoplasma Gondii Infections in Wild Rodents: 2009-2020
J Parasitol. 2021 Mar 1;107(2):182-204. doi: 10.1645/20-121.ABSTRACTToxoplasma gondii infections are common in humans and animals worldwide. Rodents are one of the most important intermediate hosts for T. gondii because they are preyed on by cats, who in turn excrete the environmentally resistant oocysts in their feces and thus spread the infection. Information on T. gondii infections is spread in numerous reports and is not easily accessible to readers. Here, we review prevalence, persistence of infection, clinical disease, epidemiology, and genetic diversity of T. gondii infections in wild rodents worldwide. Data are tab...
