The detection of Leishmania tarentolae in sympatric areas where Leishmania infantum is endemic raised questions regarding the protective effect exerted in dogs by L. tarentolae when in coinfection. This study aimed monitoring the in vitro gene expression of pro- (IFN- γ; TNF-α; IL-12) and anti-inflammatory (IL-4; IL-6; IL-10) cytokines in primary canine macrophages infected by L.

Article Synopsis
  • The study focuses on five species of Phortica flies in Europe and the Middle East, particularly Phortica variegata and Phortica okadai, known as vectors for the zoonotic eyeworm Thelazia callipaeda, in a region near Rome, Italy.
  • Over three years (2018-2020), researchers collected and identified nearly 5,600 flies, revealing a dominance of Phortica variegata, which was found to be infected with T. callipaeda, while Phortica oldenbergi showed differing behavior in fruit traps.
  • Environmental factors like temperature, wind speed, and pressure influenced the population dynamics of these species, with the study being the first to explore these ecological interactions

Colpodella species are close relatives of Apicomplexan protozoa. Although most species of this genus are free-living organisms that feed on other protists and algae, reports indicate their occurence in ticks and human patients, including an individual with a history of tick bite manifesting neurological symptoms. During an investigation of tick-borne pathogens (TBPs) in blood samples of cattle, goats, and in ticks collected on them, Colpodella sp.

Leishmania tarentolae is a non-pathogenic species first isolated from geckoes in the Mediterranean basin. The finding that dogs test positive against both Leishmania infantum and L. tarentolae raises questions regarding the ability of the latter species to persist and adapt to new hosts.

  • Wolbachia is a type of bacteria found in certain arthropods and nematodes, like Dirofilaria immitis, and may trigger a specific immune response (Th1) that could be important for combating Leishmania infantum infections in dogs.* -
  • In a study of 187 clinically healthy dogs, various tests were conducted to quantify Wolbachia and L. infantum DNA, as well as assess cytokine levels, revealing that a significant proportion of dogs positive for D. immitis were also positive for Wolbachia.* -
  • The findings indicated a complex relationship between D. immitis and Wolbachia, with cytokine levels differing among groups; notably,

Wolbachia has an obligatory mutualistic relationship with many onchocercid nematodes of the subfamilies Dirofilariinae and Onchocercinae. Till date, no attempts have been made for the in vitro cultivation of this intracellular bacterium from the filarioid host. Hence, the current study attempted cell co-culture method using embryonic Drosophila S2 and the LD cell lines to cultivate Wolbachia from Dirofilaria immitis microfilariae (mfs) harvested from infected dogs.

Bacteria of the genus Wolbachia are endosymbionts of parasitic filarial nematodes, including Dirofilaria immitis, and are a target for the treatment of canine heartworm disease. In the present study, 53 naturally-infected dogs were divided in three groups, based on their positivity to D. immitis by antigen and Knott tests, to assess the efficacy of doxycycline treatment in eliminating Wolbachia from circulating blood.

Several zoonotic vector-borne helminths (VBHs) infesting canids cause serious veterinary and medical diseases worldwide. Increasing the knowledge about their genetic structures is pivotal to identify them and therefore to settle effective surveillance and control measures. To overcome the limitation due to the heterogeneity of large DNA sequence-datasets used for their genetic characterization, available cytochrome c oxidase subunit 1 (cox1) (n = 546) and the 12S rRNA (n = 280) sequences were examined using combined bioinformatic approach (i.

Article Synopsis
  • Chile's diverse climate makes it a prime location for studying vector-borne parasites (VBPs), but research is mostly limited to specific areas.
  • A study involving 764 rural dogs and 245 foxes found various parasites, with Hepatozoon spp. prevalent in foxes, while piroplasmids and Leishmania spp. were detected in dogs.
  • The findings highlight the need for improved diagnostic and control measures for these parasites in both domestic and wild animals across the country.

Wildlife animals are recognized as reservoirs for zoonotic fungi and their faeces might play an important role in introducing pathogens into the environment. Thought wild boar (Sus scrofa) population has dramatically increased across Europe, information about their possible role in dissemination of zoonotic pathogenic yeasts in the environment is scant. Therefore, fecal samples (n = 124) from wild boars from Campania region (Southern Italy) were collected and yeasts identified biochemically and molecularly by sequencing of the internal transcribed spacer region and their phylogenetical relationship assessed.

Wolbachia, the endosymbiont of arthropods and onchocercid nematodes is present in many medically important insect species, being also considered for the indirect control of parasitic ones. Archaeopsylla erinacei is a flea species infesting hedgehogs acting as vector of Rickettsia felis, Bartonella henselae, and Rickettsia helvetica, thus having public health relevance. The Wolbachia surface protein (wsp) and 16S rRNA genes were used to determine the presence, prevalence and molecular typing of Wolbachia in this flea species collected in two regions of southern Italy.

  • Leishmania tarentolae is a non-pathogenic protozoan found in geckoes and can coexist with the pathogenic Leishmania infantum, particularly in regions where canine leishmaniasis is common, such as southern Italy.
  • The study involved testing sheltered dogs, lizards, and sand flies for both species using various methods, including antibody tests and molecular PCR techniques, to understand their circulation and potential interactions.
  • Results showed that both dogs and lizards were infected with L. tarentolae for the first time, with several sand flies also testing positive for either L. tarentolae or L. infantum, highlighting the potential transmission pathways between these hosts.

Dirofilariosis by Dirofilaria immitis and Dirofilaria repens is endemic in dogs from countries of the Mediterranean basin. Both species may infect humans, with most of the infected patients remaining asymptomatic. Based on the recent description of the southernmost hyperendemic European focus of heartworm disease in dogs from the Pelagie archipelagos, we performed a serological and molecular survey in human population of that area.

Wolbachia, a maternally transmitted Gram-negative endosymbiont of onchocercid nematodes and arthropods, has a role in the biology of their host; thus it has been exploited for the filariasis treatment in humans. To assess the presence and prevalence of this endosymbiont in reptiles and their ectoparasites, blood and tail tissue as well as ticks and mites collected from them were molecularly screened for Wolbachia DNA using two sets of primers targeting partial 16S rRNA and Wolbachia surface protein (wsp) genes. Positive samples were screened for the partial 12S rRNA and cytochrome c oxidase subunit 1 (cox1) genes for filarioids.

International trade of animals may represent a gateway for the spreading of zoonotic pathogens and their vectors. Amongst animals, reptiles are commonly illegally imported worldwide, being Italy in the fifth position of importation of these animals. Thus, the current study analysed the pathogens associated with Hyalomma aegyptium ticks, which were collected from illegally imported tortoises from North Africa to Italy.

In Europe wildlife animals such as the red fox () are considered the main reservoir for as well as a potential threat for domestic dog infection. Though this parasite is endemic in fox populations, data on infection in wolves () are still scant, having only recently been described in Northwestern Spain, in Italy, in Croatia and in Slovakia. Based on the rising number of cases of canine lungworm infection in Central Italy (Abruzzo region), the aim of the present study was to investigate the infection by in fox and wolf populations sharing the same geographical area of dogs.
