First report of Neotrombicula inopinata infestation in domestic cats from Portugal

Publication date: Available online 30 January 2019Source: Veterinary ParasitologyAuthor(s): David W. Ramilo, Carla Monteiro, Marrion Carreira, Isabel Pereira da Fonseca, Luís CardosoAbstractTrombiculids parasitize a wide variety of terrestrial vertebrates, including domestic animals, throughout the world. They are parasites only during their larval stages, causing several dermatological lesions on their hosts, such as acute dermatitis, erythema, excoriation, erosion, papules, crusts and alopecia on the ear margins, face, interdigital spaces and abdomen. Neotrombicula is one of the several genera in Trombiculidae family, which cause trombiculosis. The most common species implicated in clinical cases is Neotrombicula autumnalis. However, several reports have shown that Neotrombicula inopinata (Oudemans, 1909) can also play a role in trombiculosis. Here, we describe the first case of N. inopinata infestation in domestic cats from mainland Portugal. Since nucleic acids of Anaplasma phagocytophilum and Borrelia burgdorferi have been found in Neotrombicula autumnalis and Rickettsia spp. in Neotrombicula inopinata, a correct taxonomical identification is essential to understand the role of these mite species as possible vectors of pathogens.

Abstract Parasitic helminth infections remain a significant challenge to global health. These are highly prevalent diseases, affecting over 1 billion persons worldwide. Their prevalence is closely linked to the presence of severe poverty and its associated sub-standard housing and sanitation. The last decade has seen a remarkable increase in our understanding of the true disease burden of helminth infections, and there has been increasing momentum on the part of national and non-governmental developmental organizations for prevention and control of these diseases. The expansion in mass treatment programmes fo...

BartholomewAbstractWithin-host competition can affect outcomes of infections when parasites occupy the same niche. We investigated within-host competition and infection outcomes in Chinook salmon exposed to two genotypes of Ceratonova shasta (myxozoan parasite). We assessed i) virulence (host mortality, median days to death), ii) within-host competition (abundance in host), and iii) success (spore production, proportion of myxospore-producing h...

RemedioAbstractRhipicephalus microplus, commonly known as southern cattle tick, causes huge economic losses in the cattle industry. Its infestation affects the production of meat and milk and causes discomfort to hosts. In addition, it is the vector of Babesia spp. and Anaplasma spp. The most frequent method used to control these parasites is through synthetic acaricides. However, their indiscriminate use can be toxic for hosts ...

However, there is limited information on the effects of formaldehyde treatment at a molecular level in fishes. In the present study, transcriptome profiling was conducted to investigate the effects of formaldehyde treatment (80 mg/L, bath for 1 h every day for three consecutive days) on the liver and kidney...

In this study, an explant culture was used  as an in vitro model of buffalo intestine to evaluate the effect of Moringa leaves extract onCryptosporidium parvum (C. parvum) oocysts using light and scanning electron microscopy and measuring IFN- γ, IL-12 and IL-14 in the culture supernatants.C. parvum oocysts were collected from naturally-infected calf feces, isolated, excysted and then co-inoculated with ileal tissue explants culture medium. The prepared Moringa leaves extract was then introduced to the infected tissues in the concentrations of 100  mg/ml and 300 mg/ml. After 24 h, tissues were col...

AbstractThe impact of many unfavorable childhood traits or diseases, such as low birth weight and mental disorders, is not limited to childhood and adolescence, as they are also associated with poor outcomes in adulthood, such as cardiovascular disease. Insight into the genetic etiology of childhood and adolescent traits and disorders may therefore provide new perspectives, not only on how to improve wellbeing during childhood, but also how to prevent later adverse outcomes. To achieve the sample sizes required for genetic research, the Early Growth Genetics (EGG) and EArly Genetics and Lifecourse Epidemiology (EAGLE) cons...
