Abstract

The genus Micipsella comprises three species of filariae to date identified in lagomorphs only, whereas the other genera belonging to the subfamily Splendidofilariinae are described as parasites of birds, reptiles and mammals. In the present study seven specimens of Micipsella numidica (Seurat, 1917), collected from the hare Lepus europaeus in Italy, were characterized genetically by molecular amplification of the mitochondrial genes (12S rDNA; cox1) and the 5S rDNA gene spacer region. Phylogenetic trees inferred using available sequences from filariae and those identified in this study evidenced a close relationship between M. numidica and Splendidofilariinae of other mammals and reptiles (Rumenfilaria andersoni and Madathamugadia hiepei). The present findings, apart from adding new data about the hosts in Italy, support the taxonomic position of M. numidica and highlight the substantial biological and molecular differences existing between Splendidofilariinae and other Onchocercidae. The study also contributes to our knowledge of the molecular/genetic diagnosis of filarial parasites of veterinary and medical concern in any vertebrate or invertebrate host. [ABSTRACT FROM AUTHOR]

Abstract

Coprological examinations were made on 686 owned dogs (23% of the total number of the registered dogs) in a semiurban area of the province of Bologna including the small towns of S. Agata, S. Giovanni in Persiceto, Sala Bolognese and Crevalcore. The results of the coprological tests were evaluated in association with the data obtained from the owners about the origin and the use or function of the animals, veterinary assistance, diet, cohabitation with other dogs, and the presence of gastrointestinal conditions. Prevalence rates were 7.0% for ascarids, 3.6% for tapeworms, 7.1% for coccidia, 2.8% for hookworms, 28.6% for whipworms. On the whole, the animals positive for gastrointestinal parasites were 37.5% of those examined. Multiple linear regression analysis indicated that the presence of gastrointestinal parasites in general was influenced by the use of the animals, veterinary assistance, age, anthelminthic treatments and cohabitation with other dogs. The presence of ascarids appeared to be influenced by age and veterinary assistance; that of cestodes by veterinary assistance; that of coccidia by cohabitation with other dogs; that of whipworms by function, treatments, veterinary assistance and age. None of the variables considered in the analysis could explain the presence of hookworms. Factor analysis grouped the variables considered into 5 factors: the first was associated with veterinary assistance; the second with the animal's function and the presence of whipworms, hookworms and tapeworms; the third with cohabitation, origin and presence of coccidia; the fourth with the presence of fresh meat (cooked, raw or frozen) in the diet, age and positivity for ascarids; the fifth with sex and the presence of gastroenteric conditions.

Abstract

Cystic echinococcosis (CE) by Echinococcosis granulosus (Eg) infection was seen in a 13 years old male lemur, found dead in a zoo in Northern Italy. Necropsy revealed several transparent cysts in the lungs and in the abdominal cavity. Freefloating cysts of varying sizes were found in the peritoneal cavity, and no protoscolex was seen microscopically. Histologically, a multifocal severe parasitic granulomatous pneumonia was observed. Confirmation of E. granulosus "sensu stricto" was reached by PCR and sequencing. In view of the absence of definitive host in the zoo, located in non-endemic region for CE, it is speculated that infection introduced through translocation of lemur from endemic region (Southern Italy zoo).
