Correcting the names of two haemogregarina spp. from lizards in egypt
J Parasitol. 2024 Feb 1;110(1):54-58. doi: 10.1645/23-71.ABSTRACTTwo haemogregarine "species" names, Haemogregarina tarentannulari and Haemogregarina rawashi, were cited by Saoud et al. (1995) as having been described by Mohammed and Ramadan (1996, in press). However, the paper by Mohammed and Ramadan (1996) was never published and, therefore, these names and their authorities must be suppressed because they violate Chapter 3 (Criteria for Publication), Article 8 (What Constitutes Published Work) of the International Code of Zoological Nomenclature. The following new names are introduced to replace them based on the Princi...

Chemotaxis response of phasmarhabditis californica (family: rhabditidae) and pristionchus entomophagus (family: neodiplogasteridae) to the mucus of four slug species
In this study, we compared the chemotaxis profile of 2 slug-associated nematodes with overlapping host ranges. Phasmarhabditis californica is a facultative parasite that has been shown to express strain-dependent variation in chemoattraction profile. We tested 4 slug species to determine the attraction index of a Canadian strain of Ph. californica and a sympatric necromenic nematode, Pristionchus entomophagus. When tested against a control (distilled water), Ph. californica showed a clear (positive) attraction towards the mucus of slugs Ambigolimax valentianus, Arion rufus, and Arion fasciatus, but not Deroceras reticulatu...

Gregarina lutescens n. sp. infecting the harlequin ladybird harmonia axyridis (coleoptera: coccinellidae)
J Parasitol. 2024 Feb 1;110(1):66-78. doi: 10.1645/23-107.ABSTRACTGregarina lutescens n. sp. is described from the alimentary canal of the harlequin ladybird or multicolored Asian lady beetle, Harmonia axyridis (Coleoptera: Coccinellidae) collected from prairie fleabane, Erigeron strigosus, at Peru State College, Peru, Nemaha Co., Nebraska. Our specimens differ from all 11 known species of Gregarina infecting coccinellid beetles worldwide by differences in size and relative shape, color, and association structure. Gregarina lutescens n. sp. is smaller than 7 known species infecting coccinellid beetles but larger than the o...

Canine hookworm presence in tongatapu, tonga
In this study, blood and fecal samples were analyzed to identify the presence of endoparasites and determine packed cell volume (PCV) values for dogs in Tonga. The current data deficit in this area made it necessary to develop a methodology and collect preliminary data to assist with future research in Tonga. Fecal analysis revealed hookworm in 73% of dogs, primarily those 4-12 mo old. Hematologic evaluation revealed low to borderline low PCV in 87% of dogs. The zoonotic nature of some of the pathogens identified poses a public health risk, with a particular risk for children.PMID:38348968 | DOI:10.1645/23-5 (Source: The J...

A new species of thelohanellus (cnidaria: myxosporea: myxobolidae) from the gill of quillback, carpiodes cyprinus (cypriniformes: catostomidae), from the arkansas river drainage of oklahoma
J Parasitol. 2024 Feb 1;110(1):40-48. doi: 10.1645/23-9.ABSTRACTDuring May 2022 and again in March 2023, 5 quillbacks, Carpiodes cyprinus, were collected from the Verdigris River, Wagoner County, Oklahoma (n = 1), and the Black River, Lawrence County, Arkansas (n = 4), and their gill, gallbladder, fins, integument, musculature, and other major organs were macroscopically examined for myxozoans. Gill lamellae from the single quillback from the Verdigris River was infected with a new myxozoan, Thelohanellus oklahomaensis n. sp. Qualitative and quantitative morphological data were obtained from fresh and formalin-fixed preser...

Steinernema adamsi n. sp. (rhabditida: steinernematidae), a new entomopathogenic nematode from thailand
J Parasitol. 2024 Feb 1;110(1):22-39. doi: 10.1645/23-60.ABSTRACTA new species of entomopathogenic nematode, Steinernema adamsi n. sp., was recovered from the soil of a longan tree (Dimocarpus sp.) in Mueang Lamphun District, Thailand, using baiting techniques. Upon analysis of the nematode's morphological traits, we found it to be a new species of Steinernema and a member of the Longicaudatum clade. Molecular analyses of the ITS rDNA and D2D3 of 28S rDNA sequences further confirmed that S. adamsi n. sp. is a new species of the Longicaudatum clade, which is closely related to Steinernema guangdongense and Steinernema longi...

Seroprevalence of toxoplasma gondii infection in pigs from southwestern mississippi
This study focused on the southwestern region of Mississippi. Between July 2003 and March 2004, blood samples were collected from slaughterhouses in southwestern Mississippi and the Alcorn State University swine farm in Churchill, Mississippi. The collected blood samples were centrifuged and the sera were collected, labeled, and stored in a freezer at -20 C. The modified agglutination test was performed at dilutions of 1:25, 1:50, and 1:500. A titer of 25 was considered seropositive. Of a total of 302 samples tested, 48 (16%) were positive at a titer of 25; 29 (10%) were positive at 50; 11 (4%) were positive at 500. The se...

First record of batrachochytrium dendrobatidis in the northern netherlands
J Parasitol. 2024 Jan 1;110(1):11-16. doi: 10.1645/22-126.ABSTRACTBatrachochytrium dendrobatidis (Bd) infects amphibians and has been linked to the decline of hundreds of anuran amphibians all over the world. In the province of Groningen in the Netherlands, this fungal pathogen was not detected before this study. To determine whether Groningen was Bd-free, we surveyed 12 locations in this province in 2020 and 2021. Samples were then used to quantify the presence of Bd with a qPCR assay. In total, 2 out of 110 (∼0.02%) collected in 2020 and 11 out of 249 samples collected in 2021 tested positive for Bd. Infected amphibian...

Implications of treating parasitic infection in northern bobwhite (colinus virginianus) on overall helminth life cycle
This study was conducted to determine how reducing the parasite burden in a definitive host may affect the prevalence in intermediate hosts. Here we used the eyeworm Oxyspirura petrowi and cecal worm Aulonocephalus pennula as model species. Northern bobwhite quail (Colinus virginianus) were provided an anthelmintic medicated feed in wild systems because of convincing evidence that these parasites were suppressing their populations. Eyeworm and cecal worm prevalence were measured in Orthopterans, which act as intermediate hosts, using polymerase chain reaction. Individuals were collected from a control site, a site treated ...
