In our study, fancy southern platyfish Xiphophorus maculatus (Cyprinodontiformes, Poeciliidae) were examined due to breathing disorders and mortality. Fish came from Vietnam farm and were redistributed by international wholesaler. In fish, loss of appetite and gasping near the water surface was observed.

Article Synopsis
  • The study investigates the role of Blastocystis subtype diversity in infection outcomes and associated symptoms in 219 patients.
  • The most common subtypes identified were ST3 (29.7%) and ST4 (22.8%), with no significant associations found between these subtypes or patient factors (like age or travel history) and gastrointestinal symptoms.
  • However, younger age and conditions like skin pruritus and eosinophilia were linked to a higher likelihood of gastrointestinal issues, suggesting that Blastocystis subtype variability is not a primary factor in clinical manifestations.

The genus comprises free-living amoebae distributed in a wide variety of environments. These amoebae are clinically significant, causing opportunistic infections in humans and other animals. Despite this, limited data on sequence types and alleles are available in Italy.

Article Synopsis
  • * Recent research in Italy presents the first molecular characterization of E. bieneusi in symptomatic patients, involving 410 faecal samples that tested positive using a molecular detection method.
  • * Three different genotypes (A, C, and K) of E. bieneusi were identified, raising questions about its zoonotic potential and emphasizing the need for further studies to understand its impact on human and animal health as well as the environment.

Article Synopsis
  • * A study in Rome over two years collected stool samples from 864 symptomatic patients, identifying a 9.1% infection rate for D. fragilis, with co-infections primarily with Blastocystis sp.
  • * The research revealed that only genotype 1 was present among the infected, indicating a need for more extensive studies to better understand the prevalence, genetic diversity, and potential zoonotic transmission of D. fragilis in Italy.

Article Synopsis
  • * Microscopy revealed that giardia was the most common parasite at 29.3%, followed by other parasites like specific spp., while molecular tests confirmed the presence of giardia in 76.9% of microscopy-positive samples, with a predominance of assemblage B.
  • * The findings indicate that giardiasis is primarily transmitted among humans rather than from animals, highlighting the need for improved drinking water safety and sanitation practices to control fecal-oral disease transmission.

The Eurasian badger () is widespread in Italy and occupies different habitats. The occurrence and species of gastrointestinal parasites were evaluated in a free-ranging badger population living in a highly anthropic area in central Italy. A total of 43 fecal samples were examined using the flotation test, the Mini-FLOTAC and Baermann techniques, and a rapid immunoassay for the detection of and spp.

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.

Fragmented data are so far available on genotype diversity of in wildlife in different countries in Europe, in particular, in Italy. In the present study, sequences obtained from different Italian wild animals [12 porcupines (), 4 wild boars (), 1 wolf (), 6 Alpine chamois ()] were compared with those available from wild host species in Europe to add new data on the geographic distribution of assemblages/sub-assemblages and their transmission patterns among natural hosts. Thirty-eight sequences were obtained by MLG analysis (, , , and genes) and subsequently compared by phylogenetic and network analyses with those from wild species monitored in the last decades in Europe.

Article Synopsis
  • - The study assessed the prevalence and genotypes of a specific parasite in 168 dogs from four kennels in Tuscany, Italy, revealing that 41% tested positive for this parasite and indicating significant differences among kennels and seasons.
  • - Zoonotic genotypes A and B, along with canine-specific genotype C, were identified in the dogs tested, highlighting potential health risks for humans.
  • - Other intestinal parasites were also found at lower rates, emphasizing the need for improved monitoring and control measures for parasites in sheltered dogs.

Giardia duodenalis is the most common intestinal protozoan in humans and animals worldwide, including eight morphologically identical assemblages, infecting pets, livestock, wildlife and human beings. Assemblages A and B are those with the higher zoonotic potential, and they have been detected in several mammals other than humans; the others (C to H) show a higher host specificity. Cats can harbour both the specific Assemblage F and the zoonotic ones A and B.

The genus Giardia includes several species distinguished by morphological, biological and molecular features. Currently, eight species within the genus are retained as valid. In Italy no identification of Giardia species other than Giardia duodenalis has been so far reported.

Article Synopsis
  • Italy is home to the only European population of crested porcupines, prompting a study to assess gastrointestinal parasites in these animals in Central Italy.
  • Researchers analyzed 52 faecal samples using microscopic and molecular techniques, finding that 39 samples were positive for various parasites, with a focus on certain spp. and their genotypes.
  • The study reports the first identification of a specific infection in crested porcupines, emphasizing the need for further research on the health implications and spread of these parasites in the species.
