Ticks and hemoplasma screening in dromedary camels (Camelus dromedarius) from Somalia.

Hemotropic mycoplasmas (hemoplasmas) are small pleomorphic bacteria that parasitize the surface of red blood cells of mammals. Hemoplasmas have been described in different species from the Camelidae Family, such as llamas and alpacas (South American camelids), but data on dromedary camels (Camelus dromedarius) are limited to a few reports. Somalia has one of the world's largest dromedary camel populations, and studies on hemoplasmas and tick-borne pathogens are lacking.

Spatial Owner-Dog Seroprevalence of spp. Antibodies in Oceanic Islands and Costal Mainland of Southern Brazil.

Leptospirosis has been described as a disease neglected worldwide. Affecting humans and animals, the disease is often related to poor environmental conditions such as lack of sanitation and presence of synanthropic rodents. Despite being considered as a One Health issue, no study has focused on comparing owner-dog seroprevalence between islands and seashore mainland.

Detection of Toxoplasma gondii DNA in milk of dairy cows from southern Brazil.

Consumption of unpasteurized cow's milk may be a transmission route for some pathogenic microorganisms, but there is little information about the risk of Toxoplasma gondii infection. Blood and milk samples were collected in a paired and random fashion from 106 dairy cows and bulk-tank milk samples were also collected from each of the six farms, in southern Brazil. Serum anti-T.

Seropositivity of Anti- Antibodies in Owners and Their Dogs Living on Island and Mainland Seashore Areas of Southern Brazil.

Although toxoplasmosis has been considered among the most neglected zoonoses worldwide, no study has focused on the frequency and associated risk factors of owners and their dogs living on an island and mainland seashore areas. Accordingly, anti- IgG antibodies were screened by indirect fluorescent antibody test (IFAT) in owners and dogs from three oceanic islands and two nearby mainland harbor areas, with associated risk factors for toxoplasmosis assessed by univariable and multivariable logistic regression models. Overall, anti- seropositivity was observed in 59/328 (18.

Rapid and noninvasive diagnostic methods may provide on-site detection and immediate social isolation, used as tools to rapidly control virus spreading. Accordingly, the aim of the present study was to evaluate a commercial breath analysis test (TERA.

Risk factors associated with ticks and spp. exposure in wild boars (), hunting dogs, and hunters of Brazil.

Background And Aim: Wild boars have recently been implicated as the maintainers and carriers of spp. ticks, which are essential for spp. transmission.

Serosurvey of anti- () antibodies in hunting dogs and hunters in Brazil.

Background And Aim: Although wild boar hunting activities and the hunting dog trade in the Atlantic Forest and Cerrado biomes of Brazil overlap both with endemic and with non-endemic areas for visceral leishmaniasis, no study to date has focused on spp. exposure among hunting dogs and hunters. The aim of the present study was to assess the presence of spp.

One Health approach on human seroprevalence of anti- antibodies, spp. eggs in dogs and sand samples between seashore mainland and island areas of southern Brazil.

Toxocariasis, caused by spp. nematodes, is among the top 5 neglected parasitic diseases worldwide; however, no comprehensive study to date has serologically compared infections in people and their dogs and environmentally contaminated soil or sand of mainland and island locations. Accordingly, this study aimed to assess the seroprevalence of anti- antibodies in traditional human seashore populations, the presence of eggs in dogs' feces and hair, and the presence of eggs in environmental samples from islands compared to the adjacent mainland of southern Brazil.

Seroprevalence of Anti-Brucella spp. Antibodies in Wild Boars (Sus scrofa), Hunting Dogs, and Hunters of Brazil.

All 86 wild boars (Sus scrofa), 170 hunting dogs, and 49 hunters sampled from three Brazilian regions were seronegative to Brucella spp. by the standard tube agglutination and 2-mercaptoethanol tests, suggesting a low circulation of Brucella spp. in wild boars, hunting dogs, and hunters in such areas.

EXPOSURE OF WILD BOAR (SUS SCROFA) TO THE COMMON VAMPIRE BAT AND LACK OF IMMUNE PROTECTION TO RABIES VIRUS IN BRAZILIAN HUNTERS.

Rabies virus is recognized as one of the most fatal zoonotic agents affecting all mammals. Wild boars (Sus scrofa), classified as a large-size exotic invasive species in Brazil with nationwide hunting permitted, may serve as an extra blood source for the common vampire bat (Desmodus rotundus). Our aim was to document wild boar exposure to vampire bats to determine the seroprevalence of rabies virus antibodies in wild boars and to determine the immune status of hunters in southern and central-western Brazilian regions.

Serosurvey of anti-Neospora caninum antibodies in wild boars (Sus scrofa), hunting dogs and hunters of Brazil.

The protozoan Neospora caninum is an important cause of abortion in cattle worldwide, with domestic dogs serving as the definitive hosts. Although hunting activities have been indicated as a potential risk factor for N. caninum infection in dogs, no serological evidence has so far been reported in hunting dogs, wild boars (Sus scrofa), and hunters.

Leptospira spp. Antibody in Wild Boars (Sus scrofa), Hunting Dogs (Canis lupus familiaris), and Hunters of Brazil.

Hunting activities are a potential risk factor for human infection with Leptospira spp. and, although wild boar seroprevalence has been studied, there are no concurrent serosurveys of wild boars (Sus scrofa), hunting dogs (Canis lupus familiaris), and hunters. The aim of our study was to assess the seroprevalence of Leptospira spp.

Hemotropic mycoplasmas (hemoplasmas) in wild boars, hunting dogs, and hunters from two Brazilian regions.

Haemotropic mycoplasmas (haemoplasmas) are small pleomorphic bacteria infecting erythrocytes of several mammalian species, including human beings. No study to date has focused on the risk of bacteria exposure in hunting activities, particularly in natural environments of highly tick-infested areas. Accordingly, the present study aimed to assess haemoplasma occurrence in the complex encompassing wild boars, hunting dogs and hunters of Brazil.

Serosurvey for Pseudorabies (Aujeszky's Disease) in Free-Range Wild Boars (Sus scrofa) of Brazil.

Free-ranging wild boars (Sus scrofa) from two different Brazilian biomes were sampled. Only one of 36 (2.8%) animals tested from central-western Brazil were positive for antibodies against pseudorabies virus (PRV) by enzyme-linked immunosorbent assay.

Seroprevalence of anti-Toxoplasma gondii antibodies in wild boars (Sus scrofa), hunting dogs, and hunters of Brazil.

Seroprevalence of Toxoplasma gondii has been extensively studied in wild boars worldwide due to the emerging risk for human infection through meat consumption. However, this is the first study that reports toxoplasmosis seroprevalence in wild boars, wild boar hunters and their hunting dogs. The aim of the present study was to evaluate the seroprevalence of anti-T.

Occurrence of antibodies anti -Toxoplasma gondii, Neospora caninum and Leptospira interrogans in a captive deer herd in Southern Brazil.

A large number of Brazilian zoos keep many endangered species of deer, however, very few disease surveillance studies have been conducted among captive cervids. Blood samples from 32 Brazilian deer (Blastocerus dichotomus, Mazama nana and Mazama americana) kept in captivity at Bela Vista Biological Sanctuary (Foz do Iguaçu, Brazil) were investigated for 10 ruminant pathogens, with the aims of monitoring deer health status and evaluating any potential zoonotic risk. Deer serum samples were tested for Brucella abortus, Leptospira (23 serovars), Toxoplasma gondii, Neospora caninum, bovine viral diarrhea virus, infectious bovine rhinotracheitis virus, foot-and-mouth disease virus, western equine encephalitis virus, eastern equine encephalitis virus and Venezuelan equine encephalitis virus.

Serological and molecular survey of Leptospira spp. among cart horses from an endemic area of human leptospirosis in Curitiba, southern Brazil.

Introduction: Cart horses are a re-emerging population employed to carry recyclable material in cities.

Methods: Sixty-two horses were sampled in an endemic area of human leptospirosis. The microscopic agglutination test (MAT) and real-time polymerase chain reaction (qPCR) were performed.

Bacterial microbiota of the ocular surface of captive and free-ranging microbats: Desmodus rotundus, Diameus youngi and Artibeus lituratus.

Objectives: To investigate normal aerobic bacterial microbiota of the eye surface in vvcaptive and free-ranging bats belonging to the suborder Microchiroptera.

Animals Studied: A total of 36 bats belonging to three different species (Desmodus rotundus, Diameus youngi, and Artibeus lituratus) were used to perform this investigation. Thirteen Diameus youngi and six Desmodus rotundus were trapped in a cave, and 17 captive Artibeus lituratus were obtained from an experimental colony.

Detection of RD(Rio) strain of Mycobacterium tuberculosis in tapirs (Tapirus terrestris) from a zoo in Brazil.

Tuberculosis is a chronic infection caused by strains of the Mycobacterium tuberculosis complex and occurs in both animal and human populations. The death of a tapir showing purulent material and a hard mass in the lungs at necropsy raised suspicion of a potential disease caused by mycobacteria species in a Brazilian zoo. Later, two other tapirs with similar signs died and were further investigated.

An outbreak of tuberculosis by Mycobacterium bovis in coatis (Nasua nasua).

Mycobacterium tuberculosis complex, which includes Mycobacterium bovis, infrequently causes severe or lethal disease in captive wildlife populations. A dead coati from a wildlife triage center showing pulmonary lesions compatible with tuberculosis had raised suspicion of a potential disease caused by mycobacteria species and was further investigated. Four native coatis (Nasua nasua) with suspected mycobacterial infection were sedated, and bronchoalveolar lavages and tuberculin skin tests (TSTs) were performed.

Detection of Neospora sp. antibodies in cart horses from urban areas of Curitiba, Southern Brazil.

Neospora caninum is a protozoan parasite which affects dogs as definitive hosts and several mammalian species as intermediate hosts mainly causing abortions and central nervous system disorders. The reemerging population of cart horses for carrying recycling material in urban areas of major cities in Brazil may have an impact on disease spreading, and these animals may be used as sentinels for environmental surveillance. Thus, the present study investigated the frequency of Neospora sp.

Prevalence and molecular characterization of Mycoplasma ovis in selected free-ranging Brazilian deer populations.

Mycoplasma ovis is a hemoplasma that may cause anemia and mortality in small ruminants. Our aim was to determine whether M. ovis infects populations of free-ranging deer in Brazil.

Mycoplasma ovis in captive cervids: prevalence, molecular characterization and phylogeny.

Hemotrophic mycoplasmas (hemoplasmas) are bacteria that attach to red blood cells of mammals, leading to acute and/or subclinical disease in infected animals. It has been suggested that Mycoplasma ovis, a hemoplasma that infects sheep and goats worldwide, may also infect deer. The aim of this study was to evaluate whether South American deer are infected with M.
