Background: The purpose of this study was to investigate the current knowledge on the epidemiology of importance zoonotic parasitic diseases in free-ranging canids of Mazandaran, north of Iran. Methods: Overall, 63 small intestinal samples of animals (20 stray dogs and 43 golden jackals) were collected from April 2017 to May 2018. The intestine contents were studied to detect and identify helminth infections. Additionally, 274 fecal samples (130 dogs, 35 fox, 90 golden jackal and 19 wolf) were examined by Sheather's flotation method for detection of Taenia eggs. Results: Sixty (95.2%) animals were infected with at least one species of intestinal helminth. the intestinal helminths were found in dogs and golden jackals included: Dipylidium caninum (25.3%), Uncinaria stenocephala (52.3%), Ancylostoma caninum (41.2%), Mesocestoides spp. (33.3%) and Toxocara canis (14.2%). In fecal examination, 2.5% of samples contained Taenia eggs, and through a species-specific PCR, 1.09% of these samples were confirmed positive for Echinococcus granulosus. Conclusion: There is a high prevalence and clear risks of zoonotic helminths in free-ranging carnivores in Mazandaran province, north of Iran. Therefore, understanding the epidemiology of zoonotic parasite infection is useful for health care access both domestic animals and humans health.

A New Species

A new species, Stigmocheylus persicus sp. nov. (Trombidiformes: Prostigmata: Stigmocheylidae) is described based on adult females from Noor, Mazandaran province, northern Iran. The new species can be distinguished from other species by the following features: non-segmented peritremes; absence of setae c3; presence of setae g2; coxa II with four setae; genu I with nine setae; tarsi I–IV with 24(+2ω)–11(+1ω)-11-10 setae. This finding presents the first new species of the family Stigmocheylidae Berlese, 1910 from Asia. Additionally, an identification key to known species of Stigmocheylus is updated.

Rice striped stem borer, <em>Chilo suppressalis</em> Walker (Lepidoptera: Crambidae) is considered the major pest of rice in Iran. Because of the serious damage on rice in Northern Iran, the present study was conducted to investigate genetic diversity within populations of <em>C. suppressalis</em>, from Mazandaran using a template of cytochrome oxidase I gene, 750 bps, (<em>COI</em>). Later the haplotypes from Iran were compared with those found in other countries. According to the results of this study, there is very low genetic diversity (two haplotypes) among different populations of this pest in populations of Northern Iran. The genetic similarity and low levels of genetic diversity of these populations suggest that the pest colonization occurred relatively recently and there is high gene flow between these populations of the province. In addition, haplotypes of Mazandaran province are different with those found in other countries. The similarity of Iranian population (Simorgh) with one population from China indicated that China might be the origin of <em>C. suppresalis</em>.

Abstract Acanthamoeba is a free-living protozoan that can be found in natural and artificial environments such as hot tubs, surface water and springs and can cause severe diseases including amoebic keratitis and granulomatous amoebic encephalitis. The present study was conducted owing to the lack of research regarding genotypes of Acanthamoeba in hot springs of Mazandaran province in northern Iran. Twenty-four water samples were collected from all hot springs in Mazandaran province. After filtration through nitrocellulose membrane, samples were cultured on non-nutrient agar medium enriched with TYIS-33. The cultures were microscopically examined for the presence of Acanthamoeba. Positive cultures were analysed by polymerase chain reaction (PCR) and genotypes were determined by targeting the 18 S rRNA gene. The pathogenic potential of all positive isolates was identified using thermotolerance and osmotolerance tests. Eleven (47.8%) samples were positive for Acanthamoeba. Based on sequencing analysis, 100% of isolates belonged to the T4 genotype. Thermo- and osmo-tolerance tests showed that four (36.3%) Acanthamoeba strains were highly pathogenic. According to our research, the occurrence of Acanthamoeba in recreational hot springs could be a hazard for high risk persons. Posting warning signs and regular monitoring of these waters by health planners may therefore be useful for decreasing Acanthamoeba spp. infections.

A need exists for research that contributes to estimating the risk factors associated with the management of outdoor cats (Felis silvestris catus) and addresses the lack of such surveys in Brazil and other Latin American countries. With this in mind we aimed to: i) identify the causal factors affecting the practice of owners allowing their cats to roam freely and; ii) evaluate potential welfare risks associated with the allowance of outdoor access, based on cat owners' reports. An online questionnaire consisting of 25 questions was answered by 8,485 Brazilian cat owners and logistic regression models used to obtain odds ratios. A number of the factors significantly related to owners allowing their cats to have outdoor access were unneutered cats, the manner in which the cat was acquired, residence in rural areas, the number of cats owned, the presence of other pets in the house, younger owner age, owner declaration of not being responsible for the cat, owner perception about the role of the cat in the house, owner knowledge about cats' potential for transmitting diseases, a lack of knowledge about zoonoses, and a lack of knowledge regarding toxoplasmosis. The practice of allowing outdoor access was associated with significantly higher odds of owners reporting several welfare issues, such as frequent flea contamination, sporotrichosis, going missing, poisoning, mistreatment, and accidents. We conclude that the practice of allowing outdoor access, as reported by 37.1% of our respondents, may result in risks to feline welfare. Increasing public awareness through campaigns that highlight the risks associated with outdoor access would improve feline management practices and welfare.
