Besides presenting zoonotic potential, helminths of cats are responsible for gastrointestinal, hepatic, and pulmonary diseases. In order to identify the helminthic fauna, prevalence, mean intensity of parasitism (MIP), and mean abundance population (MAP), 146 cats from the metropolitan area of Cuiabá, Midwestern Brazil, were necropsied. In 98 these animals, 12 species of helminths were identified, comprising (species, prevalence, MIP, and MAP, respectively): nematodes (Ancylostoma braziliense[50,68% - 53,64 - 27,18], Ancylostoma tubaeforme [10,27% - 3,6 - 0,37],Toxocara cati [4,11% - 28,33 - 1,16],Physaloptera praeputialis [2,05% - 6,67 - 0,14], Capillaria feliscati [3,42% - 7,4 - 0,25], and Aelurostrongylus abstrusus[1,37%]); cestodes (Spirometra mansonoides[4,11% - 2,0 - 0,08], Dipylidium caninum[3,42% - 5,2 - 0,18], and Taenia taeniformis[0,68% - 1,0 - 0,01]); trematodes (Platynosomum fastosum [26,03% - 179,53 - 46,73]); acanthocephalans (Centrorhynchus erraticus [3,42% - 3,2 - 0,11]). Ancylostoma spp., and P. fastosum were the most prevalent with the highest MIP and MAP. We observed the presence of species of helminths with zoonotic potential. This is the first time cats parasitized with Centrorhynchus erraticusare reported in the Americas. That genus is commonly observed in wild animals.

Interactions between humans and animals can be considerably beneficial to human well-being, and the demand for domestic cats as pets has increased in recent years. Despite these benefits, however, cats may  contribute to environmental dissemination of zoonotic pathogens, with potential risks to human health. The purpose of this study was to investigate the prevalence and diversity of feline parasites of zoonotic interest in Campo Grande, the capital city of Mato Grosso do Sul state, Midwestern Brazil, where studies on feline parasitic fauna remain scarce. Fecal samples from 210 male and female cats of varying ages, sheltered at the local Center for Zoonosis Control, were examined. Spontaneous and ether centrifugal sedimentation were used to detect the parasites, found in 149 animals (71.0%), 93 (62.4%) of which were infected with a single parasitic species and 56 (37.6%) with two or more species. Ten parasitic species were detected, where Ancylostoma sp. was the most frequent (65.2%), followed by Platynosomum concinnum (21.0%), Cystoisospora sp. (7.1%), Aelurostrongylus abstrusus (1.9%), Strongyloides sp. (1.9%), Dipylidium caninum (1.4%), Giardia sp. (1.0%), Toxocara sp. (1.0%), Physaloptera praeputialis (1.0%), and Sarcocystis sp. (0.5%). The results obtained are relevant to human and veterinary public health policies and demonstrate the cats’ role in the transmission chain of parasitic zoonoses, particularly in urban areas. The findings can also serve to raise awareness among veterinarians and cat owners on the importance of preventive interventions to ensure healthier cohabitation with pets by reducing human exposure to cat borne parasites in urban areas.   Keywords: Zoonoses.

Resumo As interações entre humanos e animais podem ser consideravelmente benéficas para o bem-estar humano, e a demanda por gatos domésticos como animais de estimação aumentou nos últimos anos. Apesar desses benefícios, no entanto, os gatos podem contribuir para a disseminação ambiental de patógenos zoonóticos, com riscos potenciais para a saúde humana. O objetivo deste estudo foi investigar a prevalência e diversidade de parasitos de interesse zoonótico em felinos de Campo Grande, capital do estado de Mato Grosso do Sul, no Centro-Oeste do Brasil, onde estudos sobre a fauna parasitária felina permanecem escassos. Foram examinadas amostras fecais de 210 gatos machos e fêmeas de idades variadas, abrigados no Centro de Controle de Zoonoses local. Sedimentação espontânea e sedimentação por centrifugação em éter foram utilizadas para detectar os parasitos, encontrados em 149 animais (71,0%), 93 (62,4%) dos quais foram infectados com uma única espécie parasitária e 56 (37,6%) com duas ou mais espécies. Foram detectadas dez espécies parasitárias, sendo Ancylostoma sp. o mais frequente (65,2%), seguido por Platynosomum concinnum (21,0%), Cystoisospora sp. (7,1%), Aelurostrongylus abstrusus (1,9%), Strongyloides sp. (1,9%), Dipylidium caninum (1,4%), Giardia sp. (1,0%), Toxocara sp. (1,0%), Physaloptera praeputialis (1,0%) e Sarcocystis sp. (0,5%). Os resultados obtidos são relevantes para as políticas de saúde pública humana e veterinária e demonstram o papel dos gatos na cadeia de transmissão das zoonoses parasitárias, principalmente nas áreas urbanas. As descobertas também podem servir para conscientizar os veterinários e donos de gatos da importância de intervenções preventivas para garantir uma coabitação mais saudável com animais de estimação, reduzindo a exposição humana a parasitos transmitidos por gatos em áreas urbanas.   Palavras-chave:  Zoonoses.

In this study, 25 stray cats were caught from the urban city of Kirkuk hunted using specially designed traps. Cats were dissected and examined in order to investigate its infection with intestinal parasites. Our results indicate that all stray cats were infected with at least one type of helminthes. Three types of Trematodes were identified: Echinochasmus, Heterophyes and , Prohemistomum with infection rate of 4% for each type. Such species were identified for the first time in stray cats in the Iraq. Moreover, four types of cestodes were identified: Diplopylidium, Dipylidium caninum, Joyeuxiella and Taenia taeniaeformis with infection rate of 24% 48%, 16% and 12%, respectively. Nematodes of Physaloptera preputalis, Toxocara cati and Toxoascaris leonina were also found. The infection rate was 4% ,28% and 8% for each type, respectively. Keywords: intestinal helminthes, stray cats, Trematodes.

Background: The genus Psychotria and Palicourea are reported as a source of alkaloids and iridoids, which exhibit biological activities. This study aimed to evaluate antiproliferative and anticholinesterase activities and quantification of the alkaloids of seven species among the genus found in Mato Grosso do Sul region in Brazil. Methods: Concentrations of alkaloids were measured spectrophotometrically. The extracts were submitted to antiproliferative activity against ten cell lines. The anticholinesterase activity of the extracts was developed using brain structures of male Wistar rats: cerebral cortex, hippocampus, hypothalamus and striatum by the Ellman method. Results: Alkaloids from Psychotria and Palicourea species were quantified which showed values of 47.6 to 21.9 µg/g. Regarding the antiproliferative potential, Palicourea crocea demonstrated selectivity against the 786-0 cell line (GI50: 22.87 µg/mL). Psychotria leiocarpa inhibited cell growth against OVCAR-3 (GI50: 3.28 µg/mL), K-562 (GI50: 5.26 µg/mL), HaCaT (GI50: 27.20 µg/mL), PC-3 (GI50: 34.92 µg/mL), MCF-7 (GI50: 35.80 µg/mL) and P. capillacea showed activity against OVCAR-3 (GI50: 2.33 µg/ml) and U251 (GI50: 16.66 µg/ml). The effect of acetylcholinesterase inhibition was more effective in the hippocampus, demonstrating inhibition for Paliourea crocea, Psychotria deflexa, P. brachybotrya and P. leiocarpa of 70%, 57%, 50% and 40%, respectively, followed by P. poeppigiana and P. capillacea, inhibiting 21%, compared to the control. Conclusion: Herein, the present work showed for the first time, anticholinesterasic and antiproliferative activities of extracts of Palicourea and Psychotria seem to be mainly associated with the levels of alkaloids in the leaves of these species.

Excretory/secretory products released by helminth parasites have been widely studied for their diagnostic utility, immunomodulatory properties, as well as for their use as vaccines. Due to their location at the host/parasite interface, the characterization of parasite secretions is important to unravel the molecular interactions governing the relationships between helminth parasites and their hosts. In this study, the excretory/secretory products from adult worms of the trematode Fasciola hepatica (FhES) were employed in a combination of two-dimensional electrophoresis, immunoblot and mass spectrometry, to analyze the immune response elicited in sheep during the course of an experimental infection. Ten different immunogenic proteins from FhES recognized by serum samples from infected sheep at 4, 8, and/or 12 weeks post-infection were identified. Among these, different isoforms of cathepsin L and B, peroxiredoxin, calmodulin, or glutathione S-transferase were recognized from the beginning to the end of the experimental infection, suggesting their potential role as immunomodulatory antigens. Furthermore, four FhES proteins (C2H2-type domain-containing protein, ferritin, superoxide dismutase, and globin-3) were identified for the first time as non-immunogenic proteins. These results may help to further understand host/parasite relationships in fasciolosis, and to identify potential diagnostic molecules and drug target candidates of F. hepatica.

AbstractFive critically endangered Iberian lynxes (Lynx pardinus) and 35 other sympatric carnivores (19 feral catsFelis catus, 12 Egyptian mongoosesHerpestes ichneumon, and 4 common genetsGenetta genetta) were analysed for helminths in Sierra Morena and Doñana area (southern Spain).Ancylostoma tubaeforme, which was believed to be harmful for lynx cubs according to a previous study, was present in the only lynx and in 53% of cats analysed in Doñana (80% in adult cats). 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.

The state of Mato Grosso is the 3rd largest Brazilian state, is covered with three major Brazilian biomes, including the Pantanal, Cerrado, and Amazonia. To date, 449 ant species are recorded in literature for the state. In the present work, we documented the ants sampled along a fragmented landscape, in the municipality of Juara, in the Cerrado-Amazon transition zone in the state of Mato Grosso, Brazil. The ant species were captured with Pitfall traps installed in 20 trails with 10 traps in each (totaling 200). Our results show 151 species, belonging to 43 genera and eight subfamilies, of which 28 species were recorded for the first time in the state and five species recorded for the first time in Brazil. Most genera collected were Pheidole Westwood, 1839 (45 species) followed by Crematogaster Lund, 1831 (11 species). By highlighting species recorded for the first time in state of Mato Grosso and Brazil, we hope to encourage new discoveries and increase the general knowledge of the ant fauna of different biomes in the region.

ABSTRACT We described infracommunities, prevalence and mean intensity of infestation of ecotoparasite flies (Nycteribiidae and Streblidae) on bats in an ecotone area of Cerrado as predominant vegetation, with influence of Atlantic Forest, in the southeast of Mato Grosso do Sul. In 36 sampling nights between April 2015 and August 2016 (23,328 m².h), we captured 17 bat species, of which ten were infested, and 14 species of fly. The most abundant bats were the phyllostomids Artibeus planirostris (Spix, 1823), Glossophaga soricina (Pallas, 1776) and Carollia perspicillata (Linnaeus, 1758) and the most abundant flies were the streblids Trichobius longipes (Rudow, 1871), T. joblingi Wenzel, 1966 and Megistopoda aranea (Coquillett, 1899). Phyllostomus hastatus (Pallas, 1767) was the bat species that presented the highest infestation rate. Platyrrhinus lineatus (É. Geoffroy, 1810) and Desmodus rotundus (É. Geoffroy, 1810) were not infested. Besides that, the frequency of bats that were infested by a single species of fly was higher than the frequency of bats infested for two or more, and it may be a pattern.

Bat flies were surveyed between March, 2007 and February, 2008, in the Carnijó Private Natural Heritage Reserve (08° 07′ S and 35° 05′ W), an area of Atlantic Rainforest in the municipality of Moreno, in the Brazilian state of Pernambuco. Bats were captured biweekly using mist nets set during six hours each night. The ectoparasites were collected with tweezers and/or a brush wet in ethanol and stored in 70% ethanol. The specimens are deposited in the zoological reference collection of the Federal University of Mato Grosso do Sul. Sixteen species of streblid bat flies were collected from 10 bat species of the family Phyllostomidae. Thirteen of the these streblid species were recorded for the first time in Pernambuco.

Coleoptera of the family Geotrupidae play an important ecological role in the decomposition of animal and plant organic matter. In Brazil there is little information on the diversity and distribution of this group, thus, this work had a purpose to study Geotrupidae species, occurring in Aquidauana, MS. A survey for geotrupids was conducted in Aquidauana, Mato Grosso do Sul, Brazil. Beetles were captured using a light trap over a period of two years, from January 2006 to December 2007. A total of 907 specimens were collected and identified to eight species. From the subfamily Bolboceratinae, the species identified were Bolbapium minutum (Luederwaldt, 1929) and Pereirabolbus castaneus (Klug, 1845). In the subfamily Athyreinae the species identified were Athyreus bilobus Howden & Martínez, 1978, Parathyreus aff. bahiae, Neoathyreus aff. julietae, N. sexdentatus Laporte, 1840, N. centromaculatus (Felsche, 1909) and N. goyasensis (Boucomont, 1902). Four species (A. bilobus, N. centromaculatus, N. goyasensis and P. castaneus) are reported for the first time in Aquidauana, MS, Brazil. The most abundant species, representing 85.9% of the total capture, was B. minutum. The greatest numbers of specimens was caught from October to December of both years of the study.
