ABSTRACT

We are going to describe the female soboliphymid nematodes, which were recovered from the stomach of a Asian badger, Meles leucurus (Mammalia: Mustelidae), in Geochang-gun, Gyeongsangnam-do, Korea. In February 1998, we found 2 peculiar nematodes with a cup-like organ in the anterior end from the stomach of badger. Recovered worms were fixed with 10% formalin, cleared in glycerin-alcohol solution and observed under a light microscope with a micrometer. They were 34.46 (33.43–35.50) mm long by 2.13 mm at maximum width. Cephalic sucker cup-like, 3.34 (3.13–3.55) mm wide, 2.40 (2.25–2.55) mm long, with the oral aperture and meridionally striated on the buccal capsule. Oral aperture 2.38 mm in diameter. Circumoral membrane 0.41 (0.38–0.45) mm wide. Esophagus muscular, 4.81 (4.50–5.00) mm long by 0.80 (0.78–0.83) mm at maximum width. Vulva situated at 3.13 mm ventro-anterior level from the esophago-intestinal junction. Vagina anteriad, 3.38 mm long, making a canal from the uterus to the vulva opening. Uterus single, large. Tail 0.35 (0.33–0.38) mm long. Intrauterine eggs long elliptical, 0.058–0.065 (0.062) mm long and 0.030–0.033 (0.031) mm wide. Based on the some morphological characters and host-specificity, our specimens are nearly identical with S. baturini. Therefore, the present report describes S. baturini for the first time in Korea.

ABSTRACT

Isthmiophora hortensis (Digenea: Echinostomatidae) is a dominant echinostome in animal reservoir hosts and humans in the Republic of Korea (Korea). We intended to investigate the infection status with this echinostome species in the several species of wild animals and describe the morphological characteristics in the faunistic view point. A total of 175 animal carcasses belonging to 3 families, i.e., Canidae, Felidae and Mustelidae, were collected from the southern regions of Korea from March 2010 to July 2017. Isthmiophora spp. worms were recovered from the small intestines of each animal under a stereomicroscope after washing of intestinal contents. Isthmiophora hortensis was recovered from 4 species of wild carnivores, i.e., Nyctereutes procyonoides (3/107: 2.8%), Mustela sibirica (11/31: 35.5%), Meles lucurus (2/3: 33.3%) and Martes flavigula (1/2: 50%). The other 3 carnivores comprising stray dogs, cat and leopard cat were negative for I. hortensis infection (0/2, 0/10 and 0/12, respectively). Specimens obtained from the Lutra lutra (6/8: 75%) were identified as a distinct species, I. inermis, by morphological comparison. Isthmiophora inermis has thinner body, elongate testes and different anterior limits of vitelline fields. Detailed morphological descriptions and comparisons with the morphological characteristics are provided. Conclusively, it was confirmed for the first time that 3 species of mustelid mammals, i.e., M. sibirica, M. lucurus, and M. flavigula, are to be the new definitive hosts of I. hortensis in Korea. Additionally, I. inermis is to be newly added in the Korean echinostome fauna.

ABSTRACT

The Dioctophyme renale is a helminth parasite of the kidney usually seen in domestic and wild carnivores and rarely in human beings. This is a report about the parasitism of D. renale found in the kidney of two roadkill lesser grisons (Galictis cuja) in the North of the state of Santa Catarina, Brazil. The report of this parasitism in this species is important to complement the records about this native carnivore as a contributor in the epidemiologic chain while host/disseminator of this helminth with zoonotic potential.(AU)


O Dioctophyme renale é um helminto parasita renal observado normalmente em carnívoros domésticos e silvestres e excepcionalmente em seres humanos. Relata-se o parasitismo por D. renale em rim de dois furões pequenos (Galictis cuja) encontrados mortos por atropelamento no Norte do estado de Santa Catarina, Brasil. Relatar esse parasitismo nessa espécie é importante, para que se possam somar dados relativos a participação deste carnívoro nativo na cadeia epidemiológica como hospedeiro/ veiculador desse helminto com potencial zoonótico.(AU)

ABSTRACT

Infections of Toxoplasma gondii and Babesia microti are reported in many wild animals worldwide, but information on their incidence and molecular detection in Korean wild fields is limited. In this study, the prevalence of T. gondii and B. microti infection in blood samples of 5 animal species (37 Chinese water deer, 23 raccoon dogs, 6 roe deer, 1 wild boar, and 3 Eurasian badgers) was examined during 2008–2009 in Gangwon-do (Province), the Republic of Korea (=Korea) by using serological and molecular tests. The overall seropositivity of T. gondii was 8.6% (6/70); 10.8% in Chinese water deer, 4.3% in raccoon dogs, and 16.7% in roe deer. PCR revealed only 1 case of T. gondii infection in Chinese water deer, and phylogenic analysis showed that the positive isolate was practically identical to the highly pathogenetic strain type I. In B. microti PCR, the positive rate was 5.7% (4/70), including 2 Chinese water deer and 2 Eurasian badgers. Phylogenetic analysis results of 18S rRNA and the β-tubulin gene showed that all positive isolates were US-type B. microti. To our knowledge, this is the first report of B. microti detected in Chinese water deer and Eurasian badger from Korea. These results indicate a potentially high prevalence of T. gondii and B. microti in wild animals of Gangwon-do, Korea. Furthermore, Chinese water deer might act as a reservoir for parasite infections of domestic animals.

ABSTRACT

Abstract The current study aimed to investigate the helminth parasites of a population of Galictis cuja (Carnivora, Mustelidae) that occur in Atlantic Forest in the Southeastern region of Brazil. We necropsied 18 specimens of G. cuja, collected between January 2009 and May 2014, ran over victims on BR-040 highway, between the municipalities of Duque de Caxias, state of Rio de Janeiro and Juiz de Fora, state of Minas Gerais, localities inserted in Atlantic rainforest Biome. A total of six species of helminths were identified: Dioctophyme renale, Molineus elegans, Physaloptera sp., Strongyloides sp., Platynosomum illiciens, and Pachysentis gethi. Molineus elegans, Physaloptera sp. and P. illiciens were recorded for the first time in this host. Data provided in the current study when compared to the previous reports of parasitism by helminths in G. cuja in Brazil demonstrate that this study is the most representative with this host species.

ABSTRACT

The dorsal surface structure of the lingual papillae in the least weasel was compared with that of other carnivorous mammalian species. Two types of mechanical papillae (filiform and conical) and two types of gustatory papillae (fungiform and vallate) were observed. The filiform papillae had secondary processes. Rarely conical papillae were observed. A few taste buds were seen on the surfaces of the fungiform papillae. The four vallate papillae were located on both sides of the posterior end of the lingual body. In conclusion, morphological characteristics of the lingual papillae and their distribution in the least weasel were similar to those of the Japanese marten and ferret. The conical papillae in the lingual apex of the Japanese marten and ferret were not observed, but the conical papillae were seen in the lingual apex of the least weasel.


La estructura de la superficie dorsal de las papilas linguales en la comadreja se comparó con la de otras especies de mamíferos carnívoros. Se observaron dos tipos de papilas mecánicas (filiformes y cónicas) y dos tipos de papilas gustativas (fungiformes y circunvaladas). Las papilas filiformes presentaron procesos secundarios. En raras ocasiones se observaron papilas cónicas. Unas pocas papilas gustativas fueron observadas en las superficies de las papilas fungiformes. Las cuatro papilas circunvaladas se encuentran a ambos lados de la parte posterior de la lengua. En conclusión, las características morfológicas de las papilas linguales y su distribución de la comadreja menor fueron similares a los de la marta y hurones japonés. No se observaron papilas cónicas en el ápice de la lengua de la marta y hurón japonés, pero si en el ápice de la lengua de la comadreja común.

ABSTRACT

<p><b>OBJECTIVE</b>To elucidate the characteristics of genetic variability and its relationship with prevalence, through sequencing and analysis of N gene among street rabies virus isolated from different hosts (homo sapiens, ferret badger, dog) in Zhejiang province.</p><p><b>METHODS</b>Samples were screened and confirmed by direct fluorescence assay and reverse transcript PCR. Sequences were analyzed using bio-information software.</p><p><b>RESULTS</b>Eighteen street rabies virus strains were identified, including 2 from homo sapiens, 5 from ferret badger, and 11 from dog. Similarities of N gene and N protein were calculated to be 89.7%-100.0% and 98.4%-100.0% respectively. Mutations occurred in N gene were almost non-sense mutations. In addition,Data from phylogenetic analysis showed that all these strains could be classified into traditional genotype 1.</p><p><b>CONCLUSION</b>The prevalence of rabies viruses among different hosts in Zhejiang province had certain regional properties. Rabies viruses isolated from the same kind of host or from the same/adjacent county/counties had the closest relationship. However, the characteristics of rabies virus prevalent in homo sapiens were somewhat complicated. In summary, the transmission of street rabies virus in Zhejiang province was from dogs to ferret badgers and homo sapiens, and the virus could circulate and cross-regional transmit among dogs and ferret badgers.</p>

ABSTRACT

Infectious diseases in wild animals have been increasing as a result of their habitat alterations and closer contact with domestic animals. Canine distemper virus (CDV) has been reported in several species of wild carnivores, presenting a threat to wildlife conservation. We described the first case of canine distemper virus infection in lesser grison (Galictis cuja). A free-ranging individual, with no visible clinical sigs, presented sudden death after one day in captivity. Molecular diagnosis for CDV infection was performed using whole blood collected by postmortem intracardiac puncture, which resulted positive. The virus phylogeny indicated that domestic dogs were the probable source of infection.


Doenças infecciosas em animais selvagens têm aumentado devido às alterações em seu habitat e ao maior contato com animais domésticos. A cinomose já foi descrita em diversas espécies de carnívoros selvagens, representando uma ameaça à conservação da vida selvagem. Nesse estudo é descrito o primeiro caso de infecção pelo vírus da cinomose em um furão (Galictis cuja). Um indivíduo de vida livre, sem sinais clínicos aparentes, apresentou morte súbita após um dia em cativeiro. Foi realizado o diagnóstico molecular para detecção do vírus da cinomose canina, sendo o resultado positivo. A filogenia do vírus indicou que cães domésticos foram a provável fonte de infecção.

ABSTRACT

To know the status of sparganum (plerocercoid of Spirometra erinacei) infection in the Korean wild life, several species of wild animals were captured in Gangwon-do and examined for their status of infection with spargana. From February to December 2011, a total of 62 wild boars, 5 badgers, 1 weasel, 1 Siberian chipmunk, and 53 wild rodents were captured, and their whole muscles were examined with naked eyes for the presence of spargana worms. From the weasel and 1 wild boar, a total of 5 spargana specimens were extracted. The weasel was for the first time recorded as an intermediate or paratenic/transport host of S. erinacei in Korea, and both the weasel (Mustela sibirica manchurica) and wild boar (Sus scrofa) were added to the list of wild animals carrying spargana.

ABSTRACT

L-ascorbic acid (vitamin C) is one of the well-known anti-viral agents, especially to influenza virus. Since the in vivo anti-viral effect is still controversial, we investigated whether vitamin C could regulate influenza virus infection in vivo by using Gulo (-/-) mice, which cannot synthesize vitamin C like humans. First, we found that vitamin C-insufficient Gulo (-/-) mice expired within 1 week after intranasal inoculation of influenza virus (H3N2/Hongkong). Viral titers in the lung of vitamin C-insufficient Gulo (-/-) mice were definitely increased but production of anti-viral cytokine, interferon (IFN)-alpha/beta, was decreased. On the contrary, the infiltration of inflammatory cells into the lung and production of pro-inflammatory cytokines, tumor necrosis factor (TNF)-alpha and interleukin (IL)-alpha/beta, were increased in the lung. Taken together, vitamin C shows in vivo anti-viral immune responses at the early time of infection, especially against influenza virus, through increased production of IFN-alpha/beta.

ABSTRACT

Leptospirosis is an emerging infectious disease that has been identified as both a human and animal health problem worldwide. Regular outbreaks associated with specific risk factors have been reported in Argentina. However, there are no available data concerning the genetic population level for this pathogen. Therefore, the aim of this work was to describe the genetic diversity of Leptospira interrogans through the application of two molecular typing strategies: variable number of tandem repeats (VNTR) and multilocus sequence typing (MLST). For this purpose, seven reference strains and 18 non-epidemiologically related isolates from diverse hosts and Argentinean regions were analysed. Among them, nine genotypes and seven sequence types (STs), including three unreported STs, were described using VNTR and MLST, respectively. eBURST analysis demonstrated that ST37 was the most frequent and founder genotype of a clonal complex (CCs) containing STN1 and STN3, suggesting the importance of studying the serovars belonging to this CC in Argentina. The data from maximum parsimony analysis, which combined both techniques, achieved intra-serovar discrimination, surmounted microscopic agglutination test discrepancies and increased the discriminatory power of each technique applied separately. This study is the first to combine both strategies for L. interrogans typing to generate a more comprehensive molecular genotyping of isolates from Argentina in a global context.

ABSTRACT

O estudo epidemiológico de patógenos em populações selvagens no ambiente in situ e ex situ é fundamental para implementação de programas de prevenção, controle e monitoramento de enfermidades e para elaboração de políticas públicas de saúde pública e animal. O estudo foi realizado no zoológico do Parque Estadual de Dois Irmãos no período de janeiro a julho de 2011 onde foram coletados swabs anais e otológicos referentes a 29 carnívoros silvestres cativos do zoológico. Dos swabs otológicos analisados, 1/29 (3,4%) foi positivo para Malassezia pachy dermatis no exame direto. No exame microbiológico dos swabs otológicos, observou-se maior freqüência para bactérias do gênero Bacillus 16/29 (55,2%), seguida de Sta phylococcus 15/29 (51,7%), Escherichia coli 7/29 (24,1%), Streptobacillus 1/29 (3,4%), Micrococcus 1/29 (3,4%) e Klebsiella 1/29 (3,4%). Com relação ao exame presuntivo para o gênero Salmonella a partir das amostras de swab retal, observou-se positividade para seis raposas (Cerdocyon thous) e um guaxinim (Procyon cancrivorus). O isolamento de Salmonella spp. em C. thous e em P. cancrivorus indica um risco à saúde pública, principalmente para os profissionais do zoológico que trabalham diretamente com esses animais. Essa pesquisa reforça a importância da criação de estratégias de vigilância epidemiológica voltadas para a prevenção, controle e monitoramento de potenciais reservatórios de agentes etiológicos de doenças infecciosas e parasitárias no ambiente dos zoológicos.


The epidemiological study of pathogens in wild populations in the environment in situ and ex situ is essential for implementation of prevention, control and monitoring of diseases and for development of public policies for public and animal health. The study was conducted at the Zoo of Parque Estadual de Dois Irmãos, Recife/PE, Brazil, from January to July 2011, where we collected anal and otological swabs from 29 Zoo's captive wild carnivores. The analysis of the otological swabs showed that 1/29 (3.4%) were positive for Malassezia pachydermatis on direct examination. In the microbiological examination of otologic swabs we found mainly bacteriae of the genus Bacillus 16/29 (55.2%), followed by Staphylococcus 15/29 (51.7%), Escherichia coli 7/29 (24.1%), Streptobacillus 1/29 (3.4%), Micrococcus 1/29 (3.4%) and Klebsiella 1/29 (3.4%). Regarding the presumptive test for the genus Sal monella from rectal swabs, positive samples were observed in six foxes (Cerdocyon thous) and a raccoon (Procyon cancrivorus). The isolation of Salmonella spp. in C. thous and P. can crivorus indicates risks to public health, especially for zoo professionals who work directly with these animals. This research reinforces the importance of establishing surveillance strategies aimed at prevention, control and monitoring of potential reservoirs of the etiologic agents of infectious and parasitic diseases in the environment of zoos.

ABSTRACT

Adult gnathostomes were discovered in the stomach of the Jeju weasel, Mustela sibilica quelpartis, road-killed in Jeju-do (Province). Their morphological characters were examined to identify the species. Total 50 gnathostome adults were collected from 6 out of 10 weasels examined. In infected weasels, 4-6 worms were grouped and embedded in each granulomatous gastric tumor, except 1 weasel. Male worms were 25.0x1.4 mm in average size, and had a tail with pedunculate papillae, a spicule, and minute tegumental spines. Females were 40.0x2.5 mm in average size, and had a tail without tegumental spines. Pointed and posteriorly curved hooklets were arranged in 8-10 rows on the head bulb. Tegumental spines were distributed from behind the head bulb to the middle portion of the body. The spines were different in size and shape by the distribution level of the body surface. Fertilized eggs were 65.5x38.9 microm in average size, and had a mucoid plug at 1 pole. These gnathostomes from Jeju weasels were identified as Gnathostoma nipponicum Yamaguti, 1941. By the present study, it was confirmed for the first time that G. nipponicum is distributed in Jeju-do, the Republic of Korea, and the Jeju weasel, M. sibilica quelpartis, plays a crucial role for its definitive host.

ABSTRACT

Neste trabalho foi elaborado um etograma e analisados os efeitos qualitativos e quantitativos das diferenças de gênero de um casal de Eira barbara (Carnivora: Mustelidae) em cativeiro. Os dados foram coletados no Zoológico do Parque Estadual Dois Irmãos, Recife - PE, no período de abril a outubro de 2005. Para o etograma, utilizou-se o método Ad Libitum, no horário das 07:00h às 17:00h. Em seguida foram realizadas observações sistemáticas através de Varredura Instantânea para a distribuição do comportamento em um total de 100h. Foram obtidas então 58 condutas comportamentais agrupadas em duas categorias: Individual, com 40 diferentes comportamentos divididos em oito subcategorias; e Social, com 18 comportamentos divididos em três subcategorias. Deste total os comportamentos ‘tentar cópula’, ‘carregar o outro’, ‘agarrar’, ‘vocalizar’ e ‘urinar sobre’ foram exclusivos ou preferencialmente exibidos pelo macho; e ‘ser carregado’, ‘tentar pegar’, ‘esfregar genitália’, ‘molhar-se’, ‘brincar’, ‘caçar’ e ‘carregar comedouro’ e “rosnar” pela fêmea


An ethogram was described and the qualitative and quantitative effects of gender differentiation was analyzed for a male and female Eira barbara (Carnivora: Mustelidae) in captivity. The study was carried out at the Dois Irmãos Zoological Park in Recife, PE Brazil, from April to October, 2005. Observations were made from 07:00h to 17:00h. An ad libitum method was followed for ethogram building, and instantaneous scan sampling for systematic observations (total of 100h observation time). Behavioral categories were grouped into two divisions, individual (40 categories), separated into seven subdivisions; and social (18 categories) separated into two subcategories. Behavior patterns that were exclusively or preferentially exhibited by the male included: attempting to copulate, carrying, grasping, vocalizing, and urinating on; the female’s main behavior categories included: to be carried, attempting to grasp, genital scent marking, getting wet, playing, hunting, carrying the feeding bowl and growling.

ABSTRACT

Trichinosis is a worldwide parasitic infection caused by ingesting an uncooked raw meat containing viable larvae of nematode Trichinella. Although most cases have been reported in Western countries, the incidence has decreased due to strict control of meat handlings and improved hygiene in these countries. In Korea, the first case of Trichinella spiralis was reported in a patient who ingested an uncooked badger. We have also experienced four cases of Trichinella spiralis infestation among family members who showed typical clinical manifestations and laboratory findings after ingesting raw wild swine meat, and herein report the finding.

Trichinosis is a worldwide parasitic infection caused by ingesting an uncooked raw meat containing viable larvae of nematode Trichinella. Although most cases have been reported in Western countries, the incidence has decreased due to strict control of meat handlings and improved hygiene in these countries. In Korea, the first case of Trichinella spiralis was reported in a patient who ingested an uncooked badger. We have also experienced four cases of Trichinella spiralis infestation among family members who showed typical clinical manifestations and laboratory findings after ingesting raw wild swine meat, and herein report the finding.
