Tick-borne zoonoses and commonly used diagnostic methods in human and veterinary medicine Parasitol. Res. (IF 1.641) Pub Date : 2021-01-18 Andrea Springer, Antje Glass, Julia Probst, Christina Strube
Around the world, human health and animal health are closely linked in terms of the One Health concept by ticks acting as vectors for zoonotic pathogens. Animals do not only maintain tick cycles but can either be clinically affected by the same tick-borne pathogens as humans and/or play a role as reservoirs or sentinel pathogen hosts. However, the relevance of different tick-borne diseases (TBDs) may

In nature, parasitic infections must be addressed as complex systems involving parasite-host relationships on a temporal and spatial scale. Since the parasites cover a great biological diversity, we can expect that wildlife are exposed simultaneously to different parasites. In this sense, the objective of this work was to determine the relationships between free-living mammals and their associated

Management of refractory Acanthamoeba keratitis, two cases Parasitol. Res. (IF 1.641) Pub Date : 2021-01-06 Mohammad Soleimani, Alireza Latifi, Bita Momenaei, Fereshte Tayebi, S. Saeed Mohammadi, Hossein Ghahvehchian
Acanthamoeba keratitis is a serious infection of the eye that can result in permanent visual impairment or blindness, caused by free-living amoebae of the genus Acanthamoeba. Early diagnosis is necessary for effective treatment of Acanthamoeba keratitis. Acanthamoeba is abundant in nature and can be found in water, soil, and air. Acanthamoeba keratitis is usually diagnosed by culture from a scraping

Lesions caused by Sarcocystis spp., parasites of opossums ( Didelphis aurita ), in acute and chronic infections in birds ( Melopsittacus undulatus ) Parasitol. Res. (IF 1.641) Pub Date : 2021-01-06 Laura da Silva Ney, Samira Salim Mello Gallo, Nicole Brand Ederli, Francisco Carlos Rodrigues de Oliveira
Protozoa of the genus Sarcocystis are obligatory heterogenous parasites with both definitive and intermediate hosts. Opossums (Didelphis aurita) can shed multiple species of Sarcocystis with birds as the intermediate host. The pathologies of Sarcocystis species in birds have not been thoroughly elucidated. Therefore, the aim of the present study to determine the main lesions that can occur in acute

Effect of methyl gallate on immune response of Biomphalaria alexandrina (Ehrenberg, 1831) snails to infection with Schistosoma mansoni (Sambon, 1907) Parasitol. Res. (IF 1.641) Pub Date : 2021-01-06 Shereen M. Mansour, Sara S. M. Sayed, Marwa T. A. Abdel-Wareth
Schistosomiasis still affects a lot of people in many developing countries. Reducing the disease dissemination has been the target of various studies. As methyl gallate has antioxidant properties, it is assumed that it can be a good candidate for stimulating the immune response of snails. So, the aim of this work is to investigate the potential of using methyl gallate as an immunostimulant to Biomphalaria

Diversity and phylogeny of Paradiplozoon species (Monogenea: Diplozoidae) parasitising endemic cyprinoids in the peri-Mediterranean area, with a description of three new Paradiplozoon species Parasitol. Res. (IF 1.641) Pub Date : 2021-01-06 Michal Benovics, Božena Koubková, Kristína Civáňová, Imane Rahmouni, Kateřina Čermáková, Andrea Šimková
The Diplozoidae are monogenean parasites of mainly cyprinoid fishes with a unique life cycle, whereby two larvae undergo anastomosis and fuse into a single cross-shaped specimen. Paradiplozoon is the most species rich and widespread genus of the family, with a distribution range covering Eurasia and Africa; however, some areas remain underexplored and their diplozoid fauna is uncertain. In the present

Species delimitation of Gyrodactylus (Monogenea: Gyrodactylidae) infecting the southernmost cyprinids (Actinopterygii: Cyprinidae) in the New World Parasitol. Res. (IF 1.641) Pub Date : 2021-01-06 Carlos Daniel Pinacho-Pinacho, Miguel Calixto-Rojas, Adriana García-Vásquez, Ismael Guzmán-Valdivieso, Juan J. Barrios-Gutiérrez, Miguel Rubio-Godoy
The genus Gyrodactylus von Nordmann, 1832 represents one of the most diverse and widespread taxa within Monogenea, with approximately 500 species described worldwide. Thirty-three species of Gyrodactylus have been recorded in Mexico, and in the last two decades, at least 26 new species have been described mainly from freshwater fish families such as poeciliids, goodeids, profundulids, characids, and

Anti-leishmanial and anti-trypanosomal natural products from endophytes Parasitol. Res. (IF 1.641) Pub Date : 2021-01-06 Jean Baptiste Hzounda Fokou, Darline Dize, Gisele Marguerite Etame Loe, Moise Henri Julien Nko’o, Jean Pierre Ngene, Charles Christian Ngoule, Fabrice Fekam Boyom
Leishmania spp. and Trypanosoma cruzi are parasites belonging to the Trypanosomatidae family and the causative agents for two very important neglected tropical diseases (NTDs), namely leishmaniasis and trypanosomiasis, respectively. Together, they affect millions of people worldwide and the number of cases is constantly rising; thus, further effort on identifying and developing non-toxic, affordable

A new species of Wellcomia (Nematoda: Oxyuridae) in the plains viscacha (Rodentia: Chinchillidae) from Argentina, an emended diagnosis and an update of the genus Wellcomia Parasitol. Res. (IF 1.641) Pub Date : 2021-01-06 Victoria Canova, María del Rosario Robles, Agustín Manuel Abba
Wellcomia species (Oxyuridae, Syphaciinae) parasitise several families of rodents from Africa, Asia and America with diverse ecological characteristics. A new species of Wellcomia is described based on specimens obtained from the plains viscacha Lagostomus maximus (Chinchillidae) from Argentina. The description includes morphometric and ecological aspects and an emended diagnosis of the genus Wellcomia

Anuran’s habitat use drives the functional diversity of nematode parasite communities Parasitol. Res. (IF 1.641) Pub Date : 2021-01-06 Lorena Euclydes, Amanda Caroline Dudczak, Karla Magalhães Campião
Understanding the processes responsible for structuring communities has been a challenge in ecology, and parasite communities are an excellent system to address this issue. The use of different diversity metrics can help us to understand the determinants of the structure of parasite communities, and in this sense, functional diversity indexes make it possible to measure the variability of organism

Wastewater-based epidemiology—surveillance and early detection of waterborne pathogens with a focus on SARS-CoV-2, Cryptosporidium and Giardia Parasitol. Res. (IF 1.641) Pub Date : 2021-01-06 Alireza Zahedi, Paul Monis, Daniel Deere, Una Ryan
Waterborne diseases are a major global problem, resulting in high morbidity and mortality, and massive economic costs. The ability to rapidly and reliably detect and monitor the spread of waterborne diseases is vital for early intervention and preventing more widespread disease outbreaks. Pathogens are, however, difficult to detect in water and are not practicably detectable at acceptable concentrations

Head lice were also affected by COVID-19: a decrease on Pediculosis infestation during lockdown in Buenos Aires Parasitol. Res. (IF 1.641) Pub Date : 2021-01-06 Federico Galassi, Isabel Ortega-Insaurralde, Victor Adjemian, Paola Gonzalez-Audino, Maria Inés Picollo, Ariel Ceferino Toloza
Pediculosis is a worldwide disease affecting school-aged children produced by the presence of the head louse, Pediculus humanus capitis De Geer, an obligate ectoparasite on the human scalp feeding exclusively on blood. Transmission occurs primarily through direct physical head-to-head contact. In March 2020, the World Health Organization (WHO) declared the COVID-19 outbreak as a pandemic. COVID-19

This study aimed to investigate the links between parasites and behavioural traits of juvenile Murray cod (Maccullochella peelii). The Murray cod is an endangered Australian freshwater fish for which restocking programs are in place and there is a growing human consumption market. However, little is known about the parasites of these fish and how these parasites influence their behaviour and survival

Using pastoralist community knowledge to locate and treat dry-season mosquito breeding habitats with pyriproxyfen to control Anopheles gambiae s.l. and Anopheles funestus s.l. in rural Tanzania Parasitol. Res. (IF 1.641) Pub Date : 2021-01-06 Eliza T. Lupenza, Japhet Kihonda, Alex J. Limwagu, Halfan S. Ngowo, Robert D. Sumaye, Dickson W. Lwetoijera
Fundamentally, larviciding with pyriproxyfen (PPF) has potential to complement Long Lasting Insecticide Nets (LLINs) and indoor residual sprays (IRS) in settings where resistance to pyrethroids and residual malaria transmission exist. In this study, we evaluated the field effectiveness of larviciding using PPF to reduce dry season productivity of mosquito breeding habitats that were located by pastoralists
