Comparison of different molecular protocols for the detection of Uncinaria stenocephala infection in dogs.

The present study aims to assess the performance of different molecular targets using various matrices of samples for the detection of Uncinaria stenocephala (US) in hookworm infected dogs. To this end, the DNA extraction was performed on the following matrices of samples: (i) larvae of US obtained from experimentally infected dogs with US with different larvae counts per microliter (µl); (ii) pure US eggs suspension in distilled water with different egg counts per µl; (iii) spiked dog fecal samples with different US eggs per gram (EPG) of feces; (iv) feces from dogs naturally infected with hookworm eggs; (v) fecal suspension with hookworm eggs recovered from the FLOTAC apparatus. All the samples were tested with four different PCR protocols targeting specific regions for the detection of both hookworms US and AC as follows: Protocol A (ITS1, 5.

Visual and whole-body quantitative analyses of Ga-DOTATATE PET/CT for prognosis of outcome after PRRT with Lu-DOTATATE.

Background: Somatostatin receptors (SSTR) represent an ideal target for nuclear theranostics applications in neuroendocrine tumors (NET). Studies suggest that high uptake on SSTR-PET is associated with response to SSTR peptide receptor radionuclide therapy (PRRT). The purpose of this study was to evaluate the role of baseline whole-body (WB)  Ga-DOTATATE PET/CT (SSTR-PET) quantitative parameters, and the presence of NET lesions without uptake on SSTR-PET, as outcome prognosticator in patients with NET treated with PRRT.

How Italian practitioners manage dirofilariosis in dogs and cats? Data of a second national survey.

The zoonotic nematodes Dirofilaria immitis and Dirofilaria repens are endemic in many European countries and their distribution is changing. A correct diagnosis is the starting point to reduce their spread and veterinary practitioners represent the first line of defense against these two vector-borne diseases in pets and humans. With the aim to better understand current knowledge by veterinarians and to compare them with the previous survey, an online questionnaire was sent to Italian companion animal veterinary facilities.

Efficacy of topical administration of prallethrin-permethrin-piperonyl butoxide (Bronco® Equine Fly Spray) for the treatment and control of flies and other nuisance insects of horses.

Numerous biting and nuisance insects are a noted cause of discomfort and stress to horses. Pyrethrins and pyrethroids have been used for many years in numerous formulations for the control of insect pests in animals, humans and environment. There are, however, few studies reporting their field efficacy in horses.

Epidemiological and molecular updates on hookworm species in dogs from southern Italy.

Background: The zoonotic hookworms Ancylostoma caninum and Uncinaria stenocephala are widespread soil-transmitted helminths in dogs in Europe. Given the veterinary and public health importance of hookworms in dogs and the recent changes in the molecular epidemiology of some species, there is a need to continuously monitor the epidemiological and molecular prevalence of these parasites also at the "local" level. The present study aimed to update the epidemiological scenario of hookworm infections in both owned and stray dogs in southern Italy and to discriminate between different hookworm species (A.

Diversity and geographic distribution of haplotypes of Dirofilaria immitis across European endemic countries.

Background: Dirofilaria immitis, also known as heartworm, is one of the most important parasitic nematodes of domestic dogs, causing a potentially serious disease, cardiopulmonary dirofilariosis, which can be lethal. This species seems to be less 'expansive' than its sister species Dirofilaria repens, and it is believed that climate change facilitates the spread of this parasite to new non-endemic regions.

Methods: In total, 122 heartworm isolates were analysed from nine endemic countries in Europe (Portugal, Spain, Italy, Greece, Hungary, Romania, Slovakia, and Ukraine) and a single isolate from Bangladesh by amplification and sequencing of two mitochondrial (mt) DNA markers: cytochrome c oxidase subunit 1 (COI) and dehydrogenase subunit 1 (NADH).

First morphometric and molecular characterization of Fasciola spp. in Northwest Tunisia.

The aim of this study was to characterize the Tunisian Fasciola spp. flukes by morphometric and molecular analyses. Flukes were collected from livers of sheep slaughtered in Sejnane slaughterhouses (Bizerte gouvernorate, Northwest Tunisia) between January and March 2021.

Comparison of Mini-FLOTAC, Flukefinder and sedimentation techniques for detection and quantification of Fasciola hepatica and Calicophoron daubneyi eggs using spiked and naturally infected bovine faecal samples.

Background: Fasciolosis (Fasciola hepatica) and paramphistomosis (Calicophoron daubneyi) are two important infections of livestock. Calicophoron daubneyi is the predominant Paramphistomidae species in Europe, and its prevalence has increased in the last 10-15 years. In Italy, evidence suggests that the prevalence of F.

Emerging risk of spp. infection in shelter dogs in southern Italy.

In southern Italy, the number of autochthonous cases of in dogs has increased considerably. This also occurs in the Campania region, particularly in coastal areas, where infections with and have been reported more frequently. Therefore the aim of the present study was to better investigate the occurrence of spp.

New distribution patterns of in Italy.

In recent decades, the number of autochthonous cases and foci of in dogs from southern regions has increased considerably, suggesting that the distribution of the species is not limited to northern Italian regions. This epidemiological picture emerges from case reports or studies in specific locations where outbreaks of heartworm disease have occasionally been reported together with the presence of mosquito vectors. To obtain a more comprehensive picture of the current distribution of .

Efficacy of oral, topical and extended-release injectable formulations of moxidectin combined with doxycycline in Dirofilaria immitis naturally infected dogs.

Background: Several studies in both experimentally and naturally infected dogs have reported the adulticide effect of a combination of macrocyclic lactones and doxycycline against Dirofilaria immitis, showing that these protocols can be used as an alternative to melarsomine. The present study evaluated the efficacy of oral, topical and extended-release injectable formulations of moxidectin when combined with doxycycline in dogs naturally infected with D. immitis from a shelter located in southern Italy.

Haplotypes of Dirofilaria repens from Poland and selected countries of Central, North-Eastern Europe and the Middle East: An evaluation on the relation between the genetic diversity and the geographic distribution of the fast-spreading parasite.

Subcutaneous dirofilariosis is a fast-spreading infection of dogs, and occasionally of other carnivores and humans. Several factors contribute to its spread, including climate change, which facilitates development and survival of Dirofilaria repens in the mosquito vector. Movement/relocation of infected definitive hosts (dogs) from endemic regions to non-endemic regions is another possible cause of local emergence and the presence of a wide variety of wild reservoirs of the parasite may also contribute to its spread.

Single and Synergistic Effects of Fenbendazole and Metronidazole Against Subclinical Infection by in Non-Human Primates in a Zoological Garden in Southern Italy.

The aim of this study was to assess the single and synergistic effects of fenbendazole (Fenb) and metronidazole (Metro) for the treatment of infection in different species of non-human primates (NHPs) housed in a zoological garden of southern Italy. Moreover, the study also aimed to better define the circulation of zoonotic assemblages in NHP and the potential occurrence of zoonotic transmission between the staff from the zoo and NHP. Briefly, six species that belonged to four families (Lemuridae, Cercopithecidae, Atelidae, and Hylobatidae) of NHP and housed in six cages (CG) were identified as positive and divided into two groups.

Transporter gene expression and Wolbachia quantification in adults of Dirofilaria immitis treated in vitro with ivermectin or moxidectin alone or in combination with doxycycline for 12 h.

Due to their marked larvicidal activity, macrocyclic lactones (MLs) are used for the prevention of heartworm disease ( Dirofilaria immitis) in dogs. They have also been shown to eliminate adult parasites after long-term administration, with a so-called "slow-kill" effect. In addition, recent studies have established that a combination of doxycycline, which eliminates the endosymbiont Wolbachia, and MLs has superior adulticide effects when compared to MLs alone.

A five-year retrospective study on ascarid infections in dogs in southern Italy.

A 5-year retrospective analysis of ascarid infections (Toxocara canis and Toxascaris leonina) in dogs from southern Italy was performed to update the epidemiological scenario of these parasites and to identify the risk factors which may favour these infections in animals in this study area. A total of 8,149 dogs, referred to our labs for copromicroscopic analysis using the FLOTAC technique, was considered. A sub-sample of 500 faecal samples were analysed also with the Mini-FLOTAC technique.

Occurrence of Species and Co-Infection with in Symptomatic Dogs and in Their Ticks in Eastern Romania.

Although the distribution of spp. and is well known in Romania, there is still a marked lack of information in many places of the country. This study aimed to investigate the occurrence of these haemoparasites in symptomatic dogs and in their ticks in Iasi, eastern Romania.

Evaluation of alternative reagents on the performance of the modified Knott's test.

The aim of the present study was to evaluate the suitability of different reagents as safe alternatives to 2% formalin in the modified Knott's test for the diagnosis of subcutaneous (Dirofilaria repens) and cardiopulmonary (D. immitis) dirofilariosis. A total of 61 blood samples from dogs naturally infected with D.

A survey on canine leishmaniosis: Best practice and guideline awareness among Italian veterinary practitioners.

Canine leishmaniosis (CanL) is a severe, potentially life-threatening disease of dogs and is considered one of the most important vector-borne zoonoses in Europe, where there is evidence that it is currently spreading into previously unaffected areas. Veterinary practitioners represent the first-line defence against CanL and in recent years, several guidelines have been developed to assist veterinarians in the correct diagnosis, management and prevention of the disease. The present study was aimed at surveying Italian practitioners on how they manage CanL and compare results to recommendations from guidelines developed by the European Scientific Council for Companion Animal Parasites (ESCCAP®), by the Leishvet® organization and by the Canine Leishmaniasis Working Group (C.

In Vitro Evaluation of Ozonated Water Treatment on the Viability of Oocysts and Cysts from Water Buffaloes: A Proof-of-Concept Study.

The aim of this proof-of-concept study was to evaluate the in vitro effects of ozonated water treatment on the viability of oocysts and cysts isolated from naturally infected water buffaloes. oocysts were divided into seven groups of six replicates that were treated with ozonated water at three ozone concentrations (0.5, 1, and 2 mg/L) and two contact times (five and ten minutes), and one group (negative control) that was exposed to non-treated water.

Effectiveness of Fenbendazole and Metronidazole Against Infection in Dogs Monitored for 50-Days in Home-Conditions.

A field trial performed in-home conditions was conducted on 24 dogs naturally infected with , in order to compare the efficacy of fenbendazole and metronidazole. Animals were allocated in groups randomly in order to obtain two groups of 12 dogs each with similar parasitic loads of cysts: dogs in Group A were treated with fenbendazole (Panacur®, Intervet Italia Srl) administered at the dose of 50 mg/kg orally once a day for 5 consecutive days, dogs in Group B were treated with metronidazole (Flagyl®, Zambon Italia Srl) administered orally at the dose of 50 mg/kg, once a day for 5 consecutive days. All the dogs that were shedding cysts after the first treatment (Day 0) were retreated (either at Day 7 or at Day 14 or at Day 21) until a negative result was obtained with the same treatment.

First report of Echinococcus granulosus sensu lato genotype G6/G7 in domestic pigs from mainland Italy.

Cystic echinococcosis (CE; Echinococcus spp.) is widespread in many domestic animal species in Italy, with the G1-G3 genotype predominating. The G7 genotype ("pig strain"), which is much less common, has only been reported in pigs and wild boar from the island of Sardinia and in wild boars from southern mainland Italy.

First report of Dirofilaria repens infection in a microfilaraemic cat from Romania.
