Abstract
BACKGROUND Infections of cats with Echinococcus granulosus is uncommon because the cat is not part of the parasite life cycle that a carnivorous and another herbivore represent. Nevertheless, it occurs incidentally when eating food or drinking water contaminated with the worm's larva, especially with the presence of the definitive host (dogs), in this case, the infections are concentrated in stray or outside cats. For this reason, this study examined the possibility of cat infection with E. granulosus and diagnosed the common genotype of this infection. OBJECTIVE This study examined the possibility of cat infection with E. granulosus and diagnosed the common genotype of this infection. METHODS Four of the 37 cats that had died in different accidents developed cystic echinococcosis (CE). The cytochrome c oxidase subunit I (COX1) gene was initially amplified and sequenced to determine if these cysts belonged to E. granulosus, in beginning. The DNA fragments resulting from sequencing were then compared and aligned with other sequences using the Gene Bank database. Finally, a phylogenetic tree was drawn according to the sequence data obtained from cox1 genes sequencing, and the MEGA 7.0 phylogenetic analysis program was utilized. RESULTS Four different sequences were deposited in the Gen Bank with accession numbers (ON795961 to ON795964), all of which belong to the G1 genotype. Approximately 84% and 100% of these sequences aligned with G1 (AB622277.1) and G1 (MG722980.1), respectively. CONCLUSIONS G1 is the dominant genotype that causes cat infections, even though the cat's EC infection was incidental.

First report of cystic echinococcosis caused by Echinococcus granulosus sensu stricto/G1 in Felis catus from the Patagonian region of Argentina. Parasitol Res 2021; 120:747-750. [PMID: 33442817 DOI: 10.1007/s00436-021-07048-4] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/24/2020] [Accepted: 01/05/2021] [Indexed: 11/30/2022]
Abstract
Two domestic cats from the Patagonia rural area in Argentina were found to be naturally infected with Echinococcus granulosus sensu stricto/G1 genotype; so far, the only species/genotype of E. granulosus sensu lato complex described to infect domestic cats. The felines developed abdominal disseminated larval disease; the diagnosis was performed by ultrasound, exploratory laparotomy, and molecular techniques. These results indicate that cystic echinococcosis must be considered for differential diagnosis of felines with abdominal distension and/or observation of vesicles through ultrasound, from endemic areas. Even though cats and dogs are carnivores, differences in digestive physiology and immunological characteristics between them could allow the development of larval or adult worm parasites. Domestic cats with cystic echinococcosis show to be environmentally infected with E. granulosus s. s./G1 eggs.

Abstract
Echinococcus granulosus sensu lato is a zoonotic agent with a life cycle consisting of definitive hosts (dogs and wild carnivores), and intermediate hosts (usually ungulates). Other animals and humans may accidentally ingest eggs and contract cystic echinococcosis, acting as aberrant hosts. A 3-year-old neutered female cat was brought to a veterinary practice in Sassari (Italy) with abdominal distension. Ultrasound showed multiple intraperitoneal vesicles, which on laparotomy were found to be metacestodes of E. granulosus. Videos of the extraction of cysts are provided. Phylogenetic analysis based on a fragment of the cytochrome oxidase subunit 1 (cox1) mitochondrial gene identified the isolate as E. granulosussensu stricto genotype G1, the most common genotype circulating in Europe and the Mediterranean basin. This is the first case report of cystic echinococcosis in domestic cats from Italy.

Abstract
AbstractA case of cystic echinococcosis (CE) in a domestic cat is described from Saint Petersburg, Russia. Ultrasonography showed numerous cysts with hyperechoic walls and anechoic contents within the cat's abdominal cavity. Molecular identification based on mitochondrial DNA genes indicated that the causative agent was Echinococcus granulosus sensu stricto (G1 strain). This is the first report of CE in a cat caused by E. granulosus sensu stricto with molecular confirmation.
