Utilização De Progesterona Em Receptoras De Embriões Equinos

Platynosomum illiciens , a trematode parasite known for its intricate life cycle, predominantly infests the liver, gallbladder, and bile ducts of domestic cats. In this study, we examined feline fecal samples from a cat sanctuary in Metropolitan Rio de Janeiro, Brazil, aiming to determine whether, even in such environments, cats retain their atavistic hunting habits, as evidenced by the presence of P. illiciens in fecal samples. The infection diagnosis utilized centrifugal sedimentation in the formalin-ethyl acetate test. Out of 72 fecal samples collected from various cats, four tested positive for P. illiciens eggs. This study serves as a reminder that even in environments where they are well-fed, cats exhibit predatory behavior, engaging in hunting and consuming prey, thus exposing themselves to parasites. It emphasizes the importance of veterinarians and cat caretakers being cognizant of the widespread presence of P. illiciens in Brazil and considering it in the differential diagnosis for cats presenting with liver or gallbladder issues. In conclusion, our findings underscore that the ancestral instinct for hunting and predation, preserved in domestic cats, persists despite fulfilling their nutritional needs.

“…The forwarded fecal samples were homogenized and processed using five coproparasitological techniques per sample: (1) the simple centrifugation-flotation method; (2) the centrifugation-flotation technique in zinc sulfate, which concentrates floating nematode eggs and cysts and protozoa oocysts; (3) the formalin-ether concentration technique, which is based on centrifugation-sedimentation to investigate the presence of trematode eggs, cestoides, and nematodes ( Monteiro, 2011 ); (4) the cone tube centrifugation technique, specific for lung larvae research ( Ueno & Gonçalves, 1998 ); (5) a fecal smear was examined for Cryptosporidium spp. oocysts using a modified Ziehl-Neelsen staining technique ( Luna, 1968 ).…”

Endoparasites of Leopardus pardalis (Carnivora, Felidae) rescued in the State of Rio de Janeiro

Wild cats play an important role as top predators in the food chain and act as ecosystem regulators. However, in recent decades, many studies have demonstrated the potential effects of parasitic diseases on wild carnivore populations, including cats. This study reports on the endoparasites found in an injured and rescued specimen of Leopardus pardalis in the state of Rio de Janeiro. Fecal samples were collected and processed using five coproparasitological techniques: a simple flotation centrifugation, a zinc sulfate flotation centrifugation, a formalin-ether sedimentation centrifugation, a conical centrifuge tube technique, and a modified Ziehl-Neelsen staining technique for fecal smears. Helminth eggs belonging to the families Trichuridae and Diphyllobothriidae and the genus Toxocara were found in both sedimentation flotation techniques. Protozoan oocysts belonging to the genus Cryptosporidium were identified by modified Ziehl-Neelsen staining. These findings show that ocelots can harbor potentially zoonotic and pathogenic endoparasites. Further studies on the helminths and protofauna of these animals are necessary.

“…It was in excellent condition and was necropsied the same day it entered the service. Subsequently, the lice were clarified in phenol-xylene (1:1) and permanently mounted in Canada balsam as described by Monteiro (2017) . For the identification, the works of Werneck (1950) and Timm and Price (1994 , 1999 ) were used.…”

“…Due to the great adaptability of rodents, some species are frequent in rural and urban areas, often being related to the transfer of pathogenic agents to other animals, such as domestic animals, including humans ( Oliveira et al, 2010 ). In addition, ectoparasites can cause damage to the hosts, as they cause weight loss and also produce lesions that predispose to secondary infections ( Monteiro, 2017 ). In Rio Grande do Sul, mentions of ectoparasites in wild animals are rare.…”

First report of parasitism by Eutrichophilus cercolabes (Phthiraptera: Trichodectidae) on Coendou spinosus (Erethizontidae) in Rio Grande do Sul, Brazil case report

Coendou spinosus is a species of rodent popularly known as porcupine, it has a great ability to adapt to different habitats and is found in tropical forests in countries such as Bolivia, Brazil, Venezuela and Guianas. This mammal has already been identified as a reservoir of several pathogenic agents for humans and other animals and has a variety of ectoparasites, endoparasites and hemoparasites little studied and described. Due to this, the objective was to report the parasitism by Eutrichophilus cercolabes in C. spinosus in the central region of Rio Grande do Sul, southern Brazil. In total, 16 lice were found, one male and 15 females of the species. This is the first report of the parasitism of this Phthiraptera on C. spinosus in Rio Grande do Sul. The scarcity of reports on the taxonomy and biotic characteristics, as well as the vector capacity of pathogens of most species of ectoparasites of wild animals, highlights the need for further studies on the distribution of these arthropods in different regions and host species.
