Gastrointestinal parasites in feral cats and rodents from the Fernando de Noronha Archipelago, Brazil

Abstract Gastrointestinal parasites are important pathogens affecting animals, some of them are of medical and veterinary concern. Although the dynamic of parasitic infections is a complex phenomenon that has been studied under experimental conditions, it shows several gaps in knowledge, especially in insular regions where a confined population of animals and parasites co-exists. In this study was assessed the parasitism by endoparasite gastrointestinal in feral cats (n = 37) and rodents (n = 30) from the Fernando de Noronha Archipelago; in addition, the risk of human infection and ecological implications of these findings were discussed. Out of all samples analysed, 100% scored positive for the presence of gastrointestinal parasites in both feral cats and rodents. A total 17 genera and/or species of endoparasite gastrointestinal were identified, Ancylostoma sp., Strongyloides sp., Trichuris campanula and Toxocara cati were the parasites more frequently in feral cats. In rodents Eimeria sp., Strongyloides sp. and Trichuris muris were parasites more frequently herein detected. Human population living in this area are at risk of parasite infections due to the population of rodents and feral cats in the archipelago.

Introduction: The present study was conducted to evaluate the prevalence of Trichuris spp. and other intestinal parasitic infections in owned cats on St. Kitts. Methodology: The feces of 41 non-feral cats (23 indoor only; 18 indoor/outdoor) were examined for the presence of Trichuris spp. eggs. Results: Nine (22%) of the cats were positive for Trichuris spp. Prevalence of trichuriasis in indoor cats was 26.0% as compared to 16.7% in outdoor cats. Other parasites identified included Ancylostoma spp. (10%; 4 cats), Toxocara cati (2%; 1 cat), Platynosomum spp. (22%; 9 cats), Mammomonogamus spp. (2%; 1 cat) and coccidia (7%; 3 cats). Conclusion: On St. Kitts, indoor cats are as likely to have parasite infections as outdoor cats. Given the zoonotic potential of some of the identified parasites, periodical anthelmintic treatment should be provided to both indoor and outdoor cats.

Abstract Gastrointestinal parasites are involved in the health and wellbeing of cats and some of them, due to their zoonotic character represent a problem for the public health. This study aimed to assess the prevalence of parasitic infections in cats with digestive symptoms. Faecal samples collected from 137 cats were analysed by the flotation method using sodium chloride saturated solution. The overall prevalence of gastrointestinal (GI) parasites was 56.6%. GI parasites were significantly (p=0.005) more common in cats with digestive symptoms (69.8%) than in clinically healthy ones (23.0%). Toxocara cati (40.2%) was the most frequently identified GI parasite, followed by Cystoisospora spp. (10.2%), Ancylostoma tubaeforme (3.7%), Taenia spp. (2.2), Giardia duodenalis (2.2%), and Toxoplasma gondii-like oocysts (0.7%). T. cati (53.3%, p<0.0001) and Cystoisospora spp. (15.6%, p<0.001) were significantly more frequently diagnosed in cats with digestive symptoms. Lack of deworming in the last three months (OR: 15.9), outdoor access (OR: 13.8), the presence of digestive symptoms (OR: 5.4), and young age (OR: 4.2) were identified as risk factors for T. cati infection by logistic regression analysis. Regardless of the age, symptoms like vomiting, diarrhoea, and inappetence were positively associated with T. cati.

Background: Leptospirosis is a re-emergent contagious infectious disease, caused by pathogenic leptospires that are transmitted by the urine of infected animals or bacteria-contaminated water and mud. In tropical and subtropical countries it presents high prevalence due to the temperature and humidity conditions that favor the maintenance of the agent in the environment. This disease can affect several species, in Brazilian cattle is an endemic disease, and studies have shown a high occurrence of Leptospira spp. infection in beef and dairy herds. Domestic cats as well as other species of the Family Felidae seem to be resistant to leptospirosis. However, it has been demonstrated under experimental conditions that cats may become infected by ingestion of infected rodents and contaminated water. The present study investigated the occurrence of Leptospira spp. infection in cattle, feral cats and rodents of the Fernando de Noronha Island.Materials, Methods & Results: Fernando de Noronha Island is located 360 km far from Recife and Natal, capitals of the states of Pernambuco and Rio Grande do Norte, Brazil, respectively. It has an area of approximately 18.4 km2 and constitutes the submerged part of a volcanic edifice currently inactive, which base rests 4,000 m deep in the Atlantic Ocean. Blood samples were collected from all the cattle raised in the Island (n = 88), 200 feral cats and 150 rodents, and the sera were screened by MAT (Serogroups: Australis; Autumnalis; Ballum; Bataviae; Canicola; Cynopteri; Djasiman; Grippotyphosa; Hebdomadis; Icterohaemorrhagiae; Icterohaemorrhagiae; Panama; Pomona; Pyrogenes; Sejroe e Tarassovi) for detection of anti-Leptospira spp. antibodies. Initially all sera were screened at 1:100 dilution and those with 50% or more agglutination were titrated at two-fold geometric dilutions. The serum titer was defined as the reciprocal of the highest positive dilution. The plane coordinates obtained by Global Position System (GPS) were used for developing a spatial map of the Fernando de Noronha Island. The geo-referenced data were plotted in the ArcGIS 10.1 software. Approximately 22% (20/88) and 12% (19/150) of the cattle and rodents were serologically reactive against Leptospira spp. antigens, respectively. The antibody titers of cattle ranged from 100 to 800 as shown. All the rodents screened were reactive against only one serovar and their antibody titers ranged from 100 to 3200. None of the serum samples from cats was reactive against the serovars tested. The serogroup Icterohaemorrhagiae predominated among the seropositive cattle, being found in 100% of the reactive samples. In rodents, the serogroups Icterohaemorrhagiae, Djasiman and Australis were responsible for 73.7% (14/19), 21.0% (4/19) and 5.2% (1/19) of the infections, respectively.Discussion: We believe that rodents and cattle play an important role in the dissemination of this disease, thus, it is necessary adopting prophylactic measures aimed at leptospirosis in the study area, in view of the human cases of leptospirosis reported and confirmed in the Island. These results are unprecedented in an insular environment in Brazil. Strategies aimed at better sanitary management of the cattle herds as well as population control of rodents must be implemented in the Fernando de Noronha Island to secure a more sustainable animal production and minimize the risks to public health.

Ex situ management of wildlife provides a possibility for species maintenance, research development and environmental education. But as captive facilities are usually much smaller than the area occupied by a species in the natural habitat, cleaning might be insufficient, domestic species such as cats might be in close proximity, and wild animals in captivity are inevitably stressed, animals kept in these facilities are more at risk of acquiring parasitic infections. Therefore, an appropriate prophylactic protocol and consequent anti-parasitic therapy of affected animals are fundamental for any wildlife conservation center. This report describes the procedures adopted in a conservation center for wild felines in which four adult Jaguarundis were diagnosed with severe infection with gastrointestinal parasites and flea infestation. Two animals died and based on the necropsy findings and fecal examinations, infections with Ancylostoma caninum and Toxocara cati were diagnosed, as well as severe infestations with Ctenocephalides felis felis fleas, all common parasites of domestic cats. We discuss the applied therapy and the adopted environmental management, along with the importance of regular health assessments and a preventive medicine program for this species in captivity.

Background: Gastro-intestinal parasitic infections in cats is a major concern for public health as they have zoonotic importance. The present research was conducted to determine the prevalence of gastro-intestinal parasitic infection in cats in different areas of Mymensingh Sadar between December, 2018 to May, 2019. Methods: The fecal samples were examined by simple sedimentation and stoll’s ova counting method for detection of eggs/cysts/oocysts of parasites. The efficacy of antiparasitics against the parasitic infections in cats was evaluated. Results: The overall prevalence of gastrointestinal parasites was 62.9% (39/62) and the mixed parasitic infection was 20.9% (13/62). The prevalence of Toxocara cati and Ancylostoma tubaeforme infections were 17.7% and 6.5%, respectively. The prevalence of Taenia pisiformis infection was 3.22%. However, the prevalence of Isospora felis, Toxoplasma gondii and Balantidium coli infections were 4.8%, 3.2% and 6.5%. The prevalence of infection was significantly (P<0.008) higher in kitten than that in adult cat. The efficacy of albendazole, fenbendazole against single helminth infection was 100%. However, the efficacy of the drug was reduced against mixed helminth infection. The efficacy of metronidazole, pyrimithamine plus sulfadoxine was 100% against single protozoa infection but the efficacy of the drug was reduced against mixed protozoal infection. Conclusions: Kittens should be dewormed with effective anthelmintics as they are more vulnerable to parasitic diseases. The T. cati, A. tubaeforme, T. gondii prevalent in cats are zoonotic and owners awareness need to be increased to prevent human infections.

Abstract The increasingly urban nature of the population has led many people to choose independent pets, such as cats. This situation has also made it possible for these animals to be abandoned, thus increasing the numbers of cats on the streets and in shelters. These animals can act as a source of infection for other hosts. Between 2014 and 2015, the frequency of gastrointestinal parasites in captive and stray cats in the municipality of Rio de Janeiro was analyzed. Ninety-one fecal samples were collected from captive cats and 172 from stray cats. Centrifugal sedimentation and flotation techniques were used. The frequency of parasites among the stray cats was 77.3%, and this was significantly higher than the frequency observed in captive cats (49.5%). Helminths were detected more frequently, and hookworms were the parasites most detected. Toxocara cati, Cystoisospora sp. and Dipylidium caninum were also detected. No statistical difference in the frequency of parasites was observed between the sexes among the captive cats. However, among the stray cats, males (85.5%) presented higher positivity than females (71.8%). The high frequency of hookworms, which are the agent for “cutaneous larva migrans” in humans, shows the need to control parasitic infections among the cats studied.

Abstract Background Little information about the prevalence of gastrointestinal parasites in yaks (Bos grunniens) in northwest China is available. Therefore, the objective of the study was to quantify faecal egg counts of gastrointestinal parasites (helminths and coccidia) in free-range yaks from Gannan Tibetan Autonomous Prefecture, Gansu Province, Northwest China. Results Parasites were detected in 290 of 733 (39.56%) faecal samples. The results showed that Strongylidae, Trichuris spp. and Eimeria spp. were detected all year round, Strongyloides papillosus was detected in autumn and summer, and Nematodirus spp. was detected in both autumn and spring. In contrast, Fasciola spp. was only detected in spring. The prevalence rates of parasitic infections in different seasons were significantly different. Conclusions To our knowledge, this is the first investigation of gastrointestinal parasites in yaks (Bos grunniens) in Gansu, China. The results demonstrated a high prevalence of gastrointestinal parasitic infections, specifically GN infections, in yaks in GTAP and these infections can cause economic losses to the local cattle industry.

Other species shared in both areas wereToxocara cati(1 lynx, 31% of cats),Joyeuxiella pasqualei(1 lynx, 21% of cats) andMesocestoidessp. (2 lynxes, 5% of cats). Only one mongoose was parasitized, harbouring larvae of two acantocephalan species not previously reported in the Iberian peninsula (Centrorhynchus(Sphaerirostris)lanceaandCentrorhynchus(Longirostris)undulatus). Feral cats may be a reservoir for hookworms and other helminths affecting the Iberian lynx. In contrast, mongooses and genets may not play a role in the epidemiology of these species.

Abstract Gastrointestinal parasites represent an important cause of reduced productivity of sheep worldwide. As anthelmintic are still the main control tool for these parasites, this work evaluated the efficacy of commercially available active principles in 22 sheep flocks in the southern region of Rio Grande do Sul, Brazil. In each farm 10 sheep were randomly distributed in seven groups with the following treatments: abamectin; albendazole; closantel; levamisole; monepantel; trichlorphon and no anthelmintic (control). All flocks showed resistance to at least three anthelmintics and in 20 farms only two products demonstrated efficacy for parasitic control. In two farms, there was no susceptibility to the six active principles tested. The results of this study provide evidence that the common commercially available anthelmintic are not assuring effective chemical control of gastrointestinal parasitic infections in ovine flocks in the southern region of Rio Grande do Sul. Monepantel, the newest introduced drug in the Brazilian market was not effective in 18% of the flocks tested, confirming that the parasitic resistance can be established quickly after the introduction of new molecules mainly when alternative program of parasite control is not performed.
