The causative agent of Chagas disease is Trypanosoma cruzi, which widely distributed throughout the South American continent and extends into North America. Its occurrence in bats poorly described may impact disease’s maintenance epidemiology. aim this study was to detect by PCR assays targeting kDNA nuclear DNA organs 203 urban rural vampire from Brazilian Atlantic Forest, São Paulo state, during pandemic period 2020 2022. In total, 6 (2.97%) were positive for T. cruzi. Infection detected...
Toxoplasmosis and neosporosis are parasitic diseases of global importance. The present study had the objective to determine influence age, sex breed in prevalence antibodies against both dogs from Brotas city, São Paulo State, Brazil. Blood samples 342 were collected, each animal recorded. serological diagnosis for toxoplasmosis performed using immunofluorescent antibody test (IFAT). Fischer's was used calculate association probability variables, with α = 5%. For 26.9% (CI 95% 22.4-31.8%),...
Q fever and brucellosis are zoonoses that cause other systemic clinical signs in humans; their occurrences neglected the differential diagnosis for some diseases is disregarded. This study aimed to investigate seropositivity Coxiella burnetii Brucella spp. antibodies patients suspected of dengue from 38 municipalities state São Paulo, Brazil. The samples (n = 604) were obtained by convenience Adolfo Lutz Institute serum bank. Sera subjected an indirect immunofluorescence assay (IFA) using...
ABSTRACT Background Toxoplasma gondii is a zoonotic parasite with great impact on the health of Neotropical primates (NP). The aim this study was to compare agreement between immunofluorescent antibody test (IFAT) and modified agglutination (MAT) detect IgG anti‐ T . antibodies in NP. Methods Convenience serum samples 77 animals were tested by IFAT MAT according standard protocols, results analyzed using McNemar's χ 2 test. Results included 30 red‐handed howlers ( Alouatta belzebul ), 24...
The performance of a commercial immunofluorescence assay (IFA commercial), an in-house in-house) and indirect enzyme-linked immunosorbent (ELISA) were evaluated in the detection antibodies anti-C. burnetii serum Q fever patients persons without disease. For study, seropositive seronegative samples for (n = 200) from bank Instituto Adolfo Lutz Brazil used. Commercial IFA was considered this study as gold standard diagnosing fever. demonstrated good agreement with test, showing high...
Abstract This study investigated infection by Leishmania spp., Leptospira Toxoplasma gondii, and Trypanosoma cruzi in six-banded armadillos (Euphractus sexcinctus) from the semiarid region of northeastern Brazil. Twenty specimens E. sexcinctus were captured alive wildlife veterinarians their natural habitats different locations. The animals euthanized following induction anesthesia, biological samples collected. Infection with four pathogens was subsequently evaluated: spleen liver...
Canine distemper virus (CDV) has been reported in several wild animal species, but there have no reports of CDV hoary fox (Lycalopex vetulus). This paper characterizes the first case natural infection fox, including clinical and pathologic aspects disease as well viral strain phylogeny.
Detection of Leptospira by PCR had not yet been described in snakes. This study investigated, microscopic agglutination test (MAT) and PCR, the presence antibodies to spp. spp., respectively, venomous non-venomous wildlife captivity All snakes were divided into three groups be compared: Group 1 (wildlife - WS); 2 (snakes intensive IC), 3 (collective semi-extensive -CC). Of 147 studied, 52 (35.4%) positive for leptospirosis MAT, 8 (15.4%) belonging (WS), 34 (65.4%) (IC) 10 (19.2%) (CC)....
The aim of this study was to investigate the occurrence Leishmania spp. antibodies, and its association with feline immunodeficiency virus (FIV) leukemia (FeLV), in domestic cats from an area endemic for canine human leishmaniasis Rio Grande do Norte State, Brazil. Ninety-one were subjected a complete clinical exam, blood samples collected. An epidemiological questionnaire used risk factors. IgG anti-Leishmania antibodies detected by immunofluorescence antibody test (IFAT), cut-off value...
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 reported several species carnivores, presenting threat to wildlife conservation. We described the first case canine infection lesser grison (Galictis cuja). A free-ranging individual, no visible clinical sigs, presented sudden death after one day captivity. Molecular diagnosis for CDV was performed using whole blood...
Concerns about the interface between wildlife, domestic animals, and humans in transmission of visceral leishmaniasis (VL) have been growing due to natural or anthropogenic environmental changes. In this context, investigations infection wild mammals are important assess their exposure vector parasite. A study anti–Leishmania (Leishmania) infantum antibodies was carried out using direct agglutination test (DAT) on 528 free-ranging 38 species from region Botucatu, state São Paulo, Brazil, a...
This study aimed to detect anti-Leptospira spp antibodies and Leptospira DNA in domestic dogs.Blood urine from 106 dogs were evaluated by microscopic agglutination test (MAT) polymerase chain reaction (PCR), respectively.Six (5.7%) one (1%) animals positive MAT PCR, respectively.These results show a low prevalence of infection spp. The absence for the Icterohaemorrhagiae serogroup indicates small relevance these as sources human leptospirosis.
ABSTRACT Aims Leishmaniasis is an endemic disease in several regions of Brazil, a tropical country that presents specific environmental conditions contribute to the development phlebotomine vectors. This study aimed detect Leishmania species naturally infected bats from 17 municipalities São Paulo state. Methods and Results Spleen liver samples 203 were analysed by real‐time PCR confirmed conventional followed gene sequencing. DNA was amplified 6.4% sequencing 3.4% bats. Positive...
The early symptoms of leptospirosis and dengue fever are difficult to distinguish can cause diagnostic confusion. Due the large epidemics that has occurred in Brazil recent years, it is possible cases were unreported. Therefore, we performed a retrospective study detect patients who tested for dengue, but whose laboratory diagnoses negative.Sera samples from 2,017 48 cities located central region São Paulo state, Brazil, studied. All subjected microscopic agglutination test (MAT), 305 which...
The aim of the current study was to evaluate infection rate by Brucella spp. in wild and captive animals. Serum samples from 121 animals (94 free-ranging 27 captive) different mammal species were evaluated. Sera submitted rose Bengal test (RBT) for screening serum agglutination tests (SAT) 2-mercaptoethanol (2-ME) confirmatory results. Nine (five four tested positive RBT, but negative tests. Several domestic animal diseases that have control programs are not focused on reservoirs, such as...
Abstract Toxoplasma gondii is one of the most important protozoa parasites worldwide. Although many seroprevalence studies have been performed in domestic and wild species, data on cumulative incidence spatial distribution T. animals are extremely scarce. In present study, dogs from Botucatu municipality, São Paulo state, were followed for year their blood samples collected three moments: days 1, 180, 360. The sera submitted to immunofluorescence antibody test (IFAT) detect IgG antibodies...
