The aim of the current study was to evaluate the infection rate by Brucella spp. in wild and in captive animals. Serum samples from 121 animals (94 free-ranging and 27 captive) of different mammal species were evaluated. Sera were submitted to rose Bengal test (RBT) for screening and serum agglutination tests (SAT) and 2-mercaptoethanol test (2-ME) for confirmatory results. Nine animals (five free-ranging and four captive) tested positive in RBT, but negative in the confirmatory tests. Several domestic animal diseases that have control programs are not focused on wild reservoirs, such as brucellosis in Brazil. The study of new reservoirs in wildlife is essential to prevent emerging diseases.

In the recent years, the wild boar (Sus scrofa) trade has increased in Brazil. The present study aimed to detect Leptospira spp. infection in 308 blood samples from wild boars bred in São Paulo state, Brazil. The microscopic agglutination test (MAT) was performed using 29 serovars. Sixty three (63; 20.45%) animals tested positive against the serovars Hardjo (29/63; 46.0%), Copenhageni (11/63; 17.4%), Pomona (8/63; 12.7%), Pyrogenes (4/63; 6.3%), Wolfii (4/63; 6.3%), Autumnalis (3/63; 4.7%), Icterohaemorraghiae (2/63; 3.1%), and Hardjo-miniswajezak (1/63; 15.8%). These results indicate that captive wild boars were infected with Leptospira spp. and may represent a source of infection to humans and other animals.

Pathology to vertebrate hosts has emerged repeatedly in the order Ophiostomatales. Occasional infections have been observed in Sporothrix mexicana at a low level of virulence, while the main pathogenic species cluster in a derived clade around S. schenckii s.str. In this paper, phylogeny and epidemiology of the members of this clade were investigated for 99 clinical and 36 environmental strains using four genetic loci, viz. rDNA ITS and partial CAL, TEF1, and TEF3; data are compared with ampliﬁed fragment length polymorphism (AFLP) genotyping. The four main species of the pathogenic clade were recognised. The species proved to show high degrees of endemicity, which enabled interpretation of literature data where live material or genetic information is...

Autores: Müller, Marina; Nishizawa, Márcia.
Cryptococcosis is an opportunist systemic mycosis considered as zoonosis caused by the complex Cryptococcus neoformans that comprises two etiologic agents, C. neoformans and C. gattii. Both of them can attack birds, humans, domestic animals and wild ones. The infection is produced by spores inhalation. These spores are often isolated from pigeon (Columba livia) faeces. These birds are considered as the natural fungus reservoir. The lesions of this disease can be found in several organ systems and it is one of the mycosis with prompt diagnosis because the infectious agent presents a marked neurological tropism, plenty of fungy elements in the CSF and in the lesions. The treatment of animals and humans must be performed with selected different drugs to...

Main parasitic zoonosis transmitted by fish - a review
Provedor de dados: 195
Autores: Okumura, Maria Paula Martinez; de Pérez, Agar Costa Alexandrino; Espíndola Filho, Antonio.
Parasitic zoonosis transmitted by fish are an ever growing problem which calls the attention of researchers and public health authorities because of the health problems caused to the population after raw / rare fish consumption. In Brazil, dishes based on raw fish, such as "sushi" and "sashimis" are greatly consumed because of the influence of oriental culinary. Data show that there are zoonotic parasites in both Brazilian fresh and sea water fish. However, up to the present, there are no reports of human parasitism in Brazil (except for fagicolosis). It is believed that this statistics are related to the absence of diagnosis rather than the absence of the illness itself. Among diseases transmitted to man by fish consumption are anisakiasis;...

Visceral leishmaniasis is a zoonotic disease caused by the protozoa of the mononuclear phagocyte system, having dogs as its main urban host. Clinical diagnosis is difficult to perform because of the diversity of clinical signs and the occurrence of asymptomatic cases. Thus, the disease is confirmed by employing laboratory methods. This study reports a case of canine visceral leishmaniasis in which the patient presented several clinical signs, and the veterinarian’s knowledge about the disease was necessary to establish the correct diagnosis.

La rabia es una zoonosis reportada por la Organización Mundial de la Salud (OMS) con una elevada mortalidad en África e Asia. Estudios realizados en Angola en las décadas de 1930- 1960 hacen mención a los perros como principales transmisores de la enfermedad diagnosticada en caninos salvajes en el laboratorio. En los últimos años se registra un número elevado de casos en el país, lo que crea un impacto de gran importancia para la salud pública. En este trabajo se analiza el comportamiento de la rabia humana en los años 2007 y 2009 en Huambo y para ello se obtuvieron los datos de los registros del Hospital General de Huambo, Departamento de Salud Pública de Huambo, informes anuales de la Dirección General y Provincial de Huambo del Instituto de los...

ABSTRACT In this study, we described the antifungal activity of three Brazilian propolis extracts: brown, green and from jataí bees against Sporothrix brasiliensis. The extracts were obtained from ethanolic extraction and their chemical composition was determined by high-performance liquid chromatography coupled to mass spectrometry. The cellular toxicity was measured in MDBK (Madin-Darby Bovine Kidney) cells and quantified by the MTT assay (3- (4,5 dimethylthiazol-2yl -2,5-diphenyl-2H bromine tetrazolato). For antifungal activity, the minimum inhibitory concentration (MIC) and minimum fungicidal concentration (MFC) were determined by broth microdilution. The results showed that cell toxicity was not observed at lower concentrations (0.097 to 0.39μg/ml)...

Systemic lupus erythematosus (SLE) is per se a disease characterized by suppressed immune response and thus susceptibility to various opportunistic infections. We describe the case of a 21-yearold woman who developed a rare zoonosis - hemotrophic mycoplasma infection in the initial stage of SLE, complicated with Nocardia asteroides pneumonia afterwards. Nocardia infection coincided with initiation of glucocorticoids and cyclophosphamide therapy for SLE. After the treatment she recovered completely. To our knowledge the only case of human hemoplasmosis (then referred to as eperythrozoonosis) in medical literature was the one described by a group of Croatian authors 22 years ago. No cases of a hemotrophic mycoplasma infection in a SLE patient have been...

OBJECTIVE: In order to evaluate the potential zoonotic transmission of Giardia duodenalis, isolates from humans and dogs in the Northwestern region of the São Paulo State, Brazil were characterized based on the β-giardin gene. METHODS: The samples were analyzed by sequencing of the Nested-PCR products. RESULTS: The A1 and A2 subgenotypes were detected in human and dogs. Cysts of assemblage B, C and D have not been found in any isolates studied. CONCLUSIONS: These results are consistent with the view that giardiasis in the largest endemic region of the Brazil should not be seen as a single entity.

Provedor de dados: 56
Autores: van der Poel,W.H.M.; Pavio,N.; van der Goot,J.; van Es,M.; Martin,M.; Engel,B.
Hepatitis E virus (HEV) is classified within the family Hepeviridae, genus Hepevirus. HEV genotype 3 (Gt3) infections are endemic in pigs in Western Europe and in North and South America and cause zoonotic infections in humans. Several serological assays to detect HEV antibodies in pigs have been developed, at first mainly based on HEV genotype 1 (Gt1) antigens. To develop a sensitive HEV Gt3 ELISA, a recombinant baculovirus expression product of HEV Gt3 open reading frame-2 was produced and coated onto polystyrene ELISA plates. After incubation of porcine sera, bound HEV antibodies were detected with anti-porcine anti-IgG and anti-IgM conjugates. For primary estimation of sensitivity and specificity of the assay, sets of sera were used from pigs...

Abstract Borreliosis caused by Borrelia burgdorferi sensu lato is a cosmopolitan zoonosis studied worldwide; it is called Lyme disease in many countries of the Northern Hemisphere and Lyme-like or Baggio-Yoshinari Syndrome in Brazil. However, despite the increasing number of suspect cases, this disease is still neglected in Brazil by the medical and veterinary communities. Brazilian Lyme-like borreliosis likely involves capybaras as reservoirs and Amblyomma and Rhipicephalus ticks as vectors. Thus, domestic animals can serve as key carriers in pathogen dissemination. This zoonosis has been little studied in horses in Brazil. The first survey was performed in the state of Rio de Janeiro, and this Brazilian Borreliosis exhibits many differences from the...

ABSTRACT: Vesicular stomatitis virus (VSV) is the agent of a vesicular disease that affects many animal species and may be clinically confounded with foot-and-mouth disease in ruminant and swine. Horses are especially susceptible to VSV and may serve as sentinels for virus circulation. The present study investigated the presence of neutralizing antibodies against VSV Indiana III (VSIV-3) in serum samples of 3,626 horses from six states in three Brazilian regions: Southern (RS, n = 1,011), Midwest (GO/DF, n = 1,767) and Northeast (PB, PE, RN and CE, n = 848) collected between 2013 and 2014. Neutralizing antibodies against VSIV-3 (titers ≥40) were detected in 641 samples (positivity of 17.7%; CI95%:16.5-19.0%), being 317 samples from CE (87.3%; CI95%:...

Increase in their population causes damage to rural properties, as they invade and destroy crops. To protect their crops and farm animals, producers hunt wild boars and often consume the product without any sanitary control, becoming exposed to various types of pathogens, including Toxoplasma gondii. Sanitary evaluations of these animals are scarce, especially in relation to the protozoan T. gondii. This study aimed to evaluate the occurrence of this pathogen in wild boars in Brazil. We analyzed 122 blood samples from wild boars (blood clots and serum), collected between 2014 and 2016 in five Brazilian states, using polymerase chain reaction (PCR) and...

ABSTRACT: Bovine vaccinia (BV) is a vesicular disease induced by the Vaccinia virus (VACV) that affects milk production and is an occupational zoonosis. This research had the following objectives: (i) detection of VACV by qPCR in cattle with clinical suspicion of vesicular disease; (ii) symptoms characterization in animals and milkers with clinical suspicion of the disease and virus detection in humans; and (iii) identification of risk factors for infections of VACV in herds from several Brazilian states. A total of 471 bovine epithelial samples from dairy farms, in 15 Brazilian states, were evaluated between 2007 and 2012. The samples were tested by quantitative PCR (qPCR) using SYBR Green® reagents, validated with a lower limit of detection of 100...

ABSTRACT:  Leishmaniasis represents a complex of chronic diseases with a broad geographic distribution and a high significance in public health worldwide. The varied clinical signs in conjunction with the low sensitivity and specificity of canine visceral leishmaniasis (CVL) detection methods make diagnosis of the disease complex. Among the several available laboratory tests, studies have suggested that the detection of parasites in synovial fluid (SF) is a good auxiliary tool in the diagnosis of CVL. However, no study has evaluated the influence of the clinical stage of CVL in the detection of Leishmania sp. in SF. This study aimed to evaluate the detection of Leishmania sp. amastigotes in the SF of dogs at different stages of the disease. The negative...

ABSTRACT: A multiplex PCR technique for detection of  Brucella spp. in samples of bacterial suspension was validated as a complementary tool in the diagnosis of the disease. This technique allows the characterization of the agent without performing biochemical tests, which greatly reduces the time for a final diagnosis, and provides more security for the analyst by reducing the time of exposure to microorganisms. The validation was performed in accordance with the Manual of Diagnostic Tests from OIE (2008) and following the requirements present in the ABNT NBR ISO/IEC 17025:2005. The mPCR validated in this study identified the different species of Brucella ( Brucella abortus ,  B. suis , B. ovis e B. melitensis ) of bacterial suspension obtained from the...

Clostridium difficile infection: main features and occurrence in domestic species in Brazil
Provedor de dados: 65
Autores: Silva,Rodrigo Otávio Silveira; Guedes,Roberto Maurício de Carvalho; Lobato,Francisco Carlos Faria.
Clostridium difficile is an emerging enteropathogen of humans and domestic animals. The bacterium was recently confirmed to be present in foals and dogs in Brazil, with some recent studies suggesting that C. difficile is one of the most important causes of piglet diarrhea in the country. Moreover, some reports also suggest the transmission of this microorganism between animals and humans, raising the possibility that C. difficile is a zoonotic disease. Therefore, the aim of the present review is to describe the main features of C. difficile infection in domestic animals and outline the occurrence of the disease in horses, dogs and pigs in Brazil.
