Carnivores may have very varied eating habits, including the consumption of insects free in the environment or within grains. The ingestion of these invertebrates is essential for the dispersion of some kinds of coccidia in nature, which occurs through stool. This study shows the presence of Adeleidae pseudoparasites in Cerdocyon thous faeces in Southern Brazil, as well as alerting veterinarians to the existence of spurious infections that may lead to misleading descriptions of new species in these hosts, or attribute wrongly the presence of these protozoa to illness symptoms.


The object of this study was estimate the frequency of reacting animals to BVDV and BoHV-1 in milk-jug bovines cattles breeding in semi-intensive system of production. Were analyzed 156 blood's serum to BVDV and 160 to BoHV-1, from bovines females, by the test of indirect ELISA. The frequency of bovines serologically reacting to BVDV and BoHV-1 were 67,30% (105/156) and 67,50% (108/160), respectively. The results acquired in this research allowed to conclude that the BVDV and BoHV-1 are present in evaluated cattles with a high frequency and the risk factors such as milk production between 1 and 5 liters when it was the BVDV and the absent of veterinary care related to BoHV-1 are related to the infection and there is a positive and strong association between both infections.

Transmissible venereal tumor (TVT) is commonly observed in the external reproductive organs of sexually active canines. However, this tumor can unusually be identified in young dogs which have not reached reproductive capacity. In these latter animals, the tumor presentation is located in regions distant from the genitalia as integument and mucous membranes of body cavities. This study aimed to describe a case of TVT in a puppy dog. A seven month old female dog of the Labrador breed, had disseminated nodules in the skin and left conjunctival mucosa. Cytological examination of the proliferation was chosen, which led to the diagnosis of TVT. Since the dog showed no genital lesions, as she was impuberal, this was considered as an extragenital case. Chemotherapy protocol was established with vincristine sulfate, with complete remission of the lesion at the end of the fourth session. Later there was recurrence of the cutaneous TVT, being employed salvage therapy with vinblastine. However there was tumor resistance to such a drug. Surgical excision of the recurrent lesion was performed. It was demonstrated that TVT may also be adapted to other tissues and affect not only dogs at reproductive age, but also those at the pre-pubertal age.

This paper reports the natural poisoning by Sida carpinifolia (guanxuma, chá-da-índia) in cattle in Rio Grande do Sul, Brazil. Five cattle were affected in the period 2001-2008. Clinical signs included weight loss, incoordination, walking difficulty, generalized tremors, frequent falls, and death. Microscopically, the main changes were vacuolation of Purkinje neurons in the cerebellum, pancreatic acinar cells, and thyroid follicular cells. Transmission electron microscopy revealed vacuoles bordered by membrane containing finely granular material. Lectin histochemistry showed positive staining in neurons with the lectins Concanavalia ensiformis (Con-A), Triticum vulgaris (WGA), and Succinyl Triticum vulgaris (sWGA).

Leishmaniosis is a zoonosis caused by protozoa of the genus Leishmania. American cutaneous leishmaniosis (ACL) is mainly caused by the species L. amazonensis and L. braziliensis, and American visceral leishmaniosis (AVL) is caused by L. infantum chagasi. In addition to their proven roles as reservoirs of AVL, dogs are also suspected by researchers to be reservoirs of ACL due to reports of this infection in domestic environments and of infected dogs in endemic areas. The aim of this study was to detect Leishmania sp. infection in dogs from Vila Operria, Buerarema, Bahia, using parasitological tests, indirect immunofluorescent assay (IFA) and polymerase chain reaction (PCR). Furthermore, this study also aimed to identify risk factors associated with illness in dogs in this locality by conducting an epidemiological survey. For this purpose, 292 dogs were clinically evaluated for the presence of skin lesions, and the dogs that showed these changes were submitted to scarification injury to enable preparation of slides for microscopic study of amastigotes. Subsequently, the dogs underwent blood sampling for serological (IFA) and molecular (PCR) tests. Additionally, the owners of the dogs answered an epidemiological questionnaire to facilitate the identification of risk factors for exposure of dogs to pathogens of ACL. Of the 292 dogs studied, 13 (4.5%) had lesions suggestive of ACL, but with a negative parasitological examination and 147 (50.3%) were seropositive according to the IFA. Of the 273 dogs studied using PCR test, 10 (3.66%) were positive for L. braziliensis, and all samples were negative for L. infantum chagasi. Wastelands in the peridomicile and the presence of light in the household were risk factors associated with ACL. The results show that Vila Operria has asymptomatic dogs with ACL and that the detection sensitivity of the IFA was higher than that of PCR for the infected dogs.

This study aimed to evaluate the presence of Staphylococcus coagulase positiva in craft cheeses produced in the city of Uberlândia-MG and to determine the incidence of samples inside and outside the standards allowed by law. We analyzed 50 samples of fresh Minas cheese, the results indicated that 88% of samples were out the standard established by the Ministry of Health for this microorganism. From these results we can conclude that the cheeses produced in the city Uberlândia not meet legal standards concerning the presence of Staphylococcus coagulase-positive, representing a health hazard.

Rabies continues to be a challenge for public health authorities and a constraint to the livestock industry in Latin America. Wild and domestic canines and vampire bats are the main transmitter species and reservoirs of the disease. Currently, variations observed in the epidemiological profile of rabies, where the species of hematophagous bat Desmodus rotundus constitutes the main transmitting species. Over the years, knowledge has accumulated about the ecology, biology and behavior of this species and the natural history of rabies, which should lead to continuous development of methods of population control of d. Rotundus as well as prevention and diagnostic tools for rabies. Ecological relationships of this species with other hematophagous and non-hematophagous bats is unknown, and there is much room for improvement in reporting systems and surveillance, as well as creating greater awareness among the farming community. Understanding the impact of human-induced environmental changes on the rabies virus in bats should be cause for further investigation. This will require a combination of field studies with mathematical models and new diagnostic tools. This review aims to present the most relevant issues on the role of hematophagous bats as reservoirs and transmitters of the rabies virus.

Over the last years, food safety has been considered the essential factor for health promotion. The supply of meals at the schools, should guarantee a nutritionally balanced meal that suits students needs, following the general food hygiene and safety norms. In this context, two systematic and quantified girds able to objectively analyze the hygiene, physical facilities and environment and sanitary conditions of the school canteens, either individually or grouped, were developed, allowing characterizing the studied establishments. Moreover, it is an enormous effort for the standardization of evaluation criteria, as needed to properly and consistently meet the reality of this sector, allowing acting at the level of Food Safety, as a priority, and the Food Quality, as added value.

The Art and Craft Fair of Boa Viagem in Recife - PE/ Brazil is much visited mainly due to their trade of typical foods. Considering, among other things, the constant risk of food contamination at the site aimed to assess the sanitary conditions of the food trade. For this, we used a checklist based on the checklist contained in Collegiate Board Resolution (RDC) n 275/02 and the determinations of RDC n° 216/04, both the National Health Surveillance Agency (Anvisa),Ministry of Health. The checklist was divided into four blocks: Exhibition of food for sale and / or consumption; Food preparation; Food handlers; and Tent facilities. From the results obtained, the tents were classified into three groups according to the percentage of items served. After analyzing the results, it was found that 25% of the blocks showed high attendance to the items evaluated, and others 75% medium and low attendance. So great are the possibilities of food contamination and hence the occurrence of foodborne diseases. It is necessary, therefore, that changes occur to the adequacy of food services to existing legislation through local infrastructure improvements, training of handlers and joint action by the regulatory agencies in order to provide safe food for the population.
