ABSTRACT Brucella ovis, a non-zoonotic species, is the etiological agent of ovine brucellosis, an infectious disease of clinical or subclinical occurrence in sheep flocks. Until then, there is no serological study of anti-Brucella ovis antibodies in purebred sheep herds. This study aimed to determine the presence of anti-Brucella ovis antibodies in purebred sheep flocks with breeding purposes from Parana State. Blood samples from 728 animals, of which 563 were females and 165 males, between 8 and 56 months of age from the six major sheep producing mesoregions of Parana, were submitted to detection of anti-Brucella ovis antibodies by the Agar Gel Immunodiffusion technique using an antigen from the bacteria Brucella ovis (Reo 198). The results indicate the presence of this disease in purebred sheep from Parana State in a low occurrence of 0.27% (2/728). The only two positive animals were rams, Santa Inês breed, from the same flock in the East Center region of Parana, without clinical disease. In conclusion, Brucella ovis is present in purebred sheep in Parana State, Brazil, and this low occurrence may have occurred due to rigorous breeding systems that may contribute to reduce the transmission of this disease.

The present work aims to estimate the seroprevalence of Bovine Enzootic Leukosis - LEB and to identify the risk factors associated with seroreactivity for infection by the LEB virus, in cattle from herds raised in the Teresina Microregion, in the State of Piaui, Brazil. 420 blood samples were examined in 14 municipalities belonging to the microregion, the technique used for the research was Immunodiffusion in Agar Gel (IDGA). There was a prevalence rate of 19.52% (82/420) of seroreagent animals, with the occurrence of at least one animal positive for LEB in each herd evaluated. The results show that prevention and control measures are necessary for better surveillance of herds.

ABSTRACT: Equine coital exanthema is a venereal infectious disease poorly reported in horses in Brazil and was never described in the northeastern region of the country. This work aims to describe the clinical and pathological aspects of an outbreak of equine coital exanthema caused by equid alphaherpesvirus 3, occurred in a herd of horses at the semiarid region of the State of Rio Grande do Norte. Main clinical signs consisted of anorexia, hiporexia, fibrinous or purulent secretion in the penis mucosa and vagina. Two mares presented mild to minimal lesions that consisted of scars in the mucosa of the vagina and in the perivulvar region. In a stallion the disease consisted of severe, multifocal, umbilicated-exanthematous ulcers of approximately 1cm in diameter on the penis mucosa. Other areas where ulcers and crusts were focally observed included the skin of the scrotum and on the lips and mucocutaneous junctions of the oral cavity. Histologically, the main lesion consisted of multifocal severe ulcerative and fibrinous necrotizing balanoposthitis and mild multifocal necrotizing, lymphocytic dermatitis in the lips and scrotum. The equide alphaherpesvirus 3 DNA was amplified in blood samples and penis mucosa using the PCR technique. This is the first report of molecular diagnosis of equine coital exanthema affecting horses in northeastern Brazil. Further studies should be carried out in order to investigate the epidemiology and the importance of this herpetic disease in the country.

Sheep breeding has been important in agribusiness, transforming the Brazilian productive scenario. However, it is still deficient due to the damages caused by infectious diseases. Leptospirosis is a severe disease with global distribution, caused by bacteria from the Leptospira genre affecting both humans and animals. The general infection is unapparent, or its clinical signs, when present, are similar to other infections. Brucellosis is an infectious disease caused by bacteria from the Brucella genre responsible for reproductive disorders in animals, especially ruminants. The purpose of this paper was to seroepidemiological study of Leptospira spp. and Brucella ovis in sheep and dogs from nonmechanized rural properties from the northwestern region in the state of Paraná, Brazil. In order to detect anti-Leptospira antibodies, microscopic agglutination (MAT) was performed. For anti-Brucella antibodies, the agar gel immunodiffusion assay (AGID) was performed. From the total 542 samples from sheep sera analyzed, 11.25% were considered reagent to Leptospira spp. and 18.26% to Brucella ovis. From the 36 dog samples, 25% were reagent to MAT and AGID. From the 32 properties analyzed, 75% were considered positive for leptospirosis and 56.25% for brucellosis. Antibodies against the most probable serovars were Hardjo (34.42%) and Butembo (44.44%) in sheep and dogs, respectively, and the variable exchange of animals among properties was associated to leptospiric infection (p=0.028) in sheep. Leptospirosis and brucellosis are present in the sheep herd and dogs in the rural properties studied, and such result is a warning of the zoonotic importance and the need to establish sanitary programs directed to these animal species.

ABSTRACT: This study aimed to carry out a serum epidemiological survey of goat arthritis encephalitis in the sisal region of Bahia, Brazil, and to evaluate risk factors. We evaluated 831 samples of goat blood serum among males and females older than six months, from 49 farms distributed among the municipalities of Araci, Cansanção, Conceição do Coité, Itiúba, Monte Santo, Nordestina, Queimadas, Santa Luz, São Domingos and Valente. An epidemiological questionnaire for the analysis of possible risk factors was applied. All sera were tested for immune-agar gel. The seroprevalence obtained in surveyed herds was 1.56% (13/831). There was significant difference (p<0.05) for animal racial pattern, type of farming and breeding systems. However, when considering herds with predominantly dairy breeds (Saanen and Alpine Pardo), the seropositivity in animals from Valente, Conceição do Coité and São Domingos amounted to 5.06% (12/237). In these municipalities, from 14 properties analyzed, five (38.5%) had at least one positive-testing animal. This result is extremely worrying when one considers that few control measures are adopted by farmers to prevent the goat arthritis encephalitis in the most important dairy region of Bahia state.

Altered State Of Consciousness

Introduction. Acute viral encephalitis is an infectious disease, which is characterized by sudden onset, serious clinical picture and with an uncertain outcome. Disturbances of consciousness are common in the course of acute viral encephalitis. Consciousness is the highest form of psychic life and consciousness disturbances may include quantitative (somnolentia, sopor, coma) and qualitative symptoms (convulsions, twilight state). Material and methods. We investigated 63 patients with acute viral encephalitis. The youngest patient was 15, and the oldest one 69 years of age. We examined the state of consciousness in all patients. Results Of all examined patients, 54 (85.72%) patients had disturbances of consciousness, 9 (14.25%) patients had no consciousness disturbances, 11 (17.46%) patients had sopor and 24 (38.09%) patients were in coma. The highest percentage of lethal outcomes was recorded in coma patients (12.5%). The longer the duration of consciousness disturbances, the higher the mortality among these patients. Discussion Subjective and objective factors cause different grades and duration of consciousness disturbances. The highest percentage of patients who recovered without consequences was established in the group of patients (81.82%) with somnolence. The highest percentage of patients who recovered with consequences (20.8%) and patients (12.5%) with lethal outcome was recorded in the group of patients in coma. These findings are in correlation with literature data. .

Resistance To Infection

To determine the presence and prevalence of bluetongue (BT) infection in a variety of domestic animal species in different geographical regions of the Sudan, a serological study using the agar gel precipitation technique was initiated. A total of 2142 serum samples were examined. Of the numbers tested approximately 28% of sheep, 11.2% of goats, 8% of cattle and 4.9% of camels were positive for group-specific antibodies to BT virus antigen, indicating previous exposure to BT infection. None of the samples tested from horses or donkeys were positive. The findings suggest that the disease is widely distributed in most parts of the Sudan where possible insect vectors prevail and may be endemic in sheep in Juba District, Equatoria Province, Southern Region. Goats appeared to have some degree of resistance to infection compared with sheep, and there seemed to be no significant differences in positive rates between farm and free-range cattle.It is concluded that BT infection may cause clinical disease in sheep, while it is probably subclinical or inapparent in goats, cattle and camels of the Sudan.

The Impact

ABSTRACTObjective: Legal preparedness is a critical component of comprehensive public health preparedness for public health emergencies. The scope of this study was to assess the usefulness of combining didactic sessions with a tabletop exercise as educational tools in legal preparedness, to assess the impact of the exercise on the participants’ level of confidence about the legal preparedness of a public health system, and to identify legal issue areas in need of further improvement.Methods: The exercise scenario and the pre- and postexercise evaluation were designed to assess knowledge gained and level of confidence in declaration of emergencies, isolation and quarantine, restrictions (including curfew) on the movement of people, closure of public places, and mass prophylaxis, and to identify legal preparedness areas most in need of further improvement at the system level. Fisher exact test and paired t test were performed to compare pre- and postexercise results.Results: Our analysis shows that a combination of didactic teaching and experiential learning through a tabletop exercise regarding legal preparedness for infectious disease emergencies can be effective in both imparting perceived knowledge to participants and gathering information about sufficiency of authorities and existence of gaps.Conclusions: The exercise provided a valuable forum to judge the adequacy of legal authorities, policies, and procedures for dealing with pandemic influenza at the state and local levels in Massachusetts. In general, participants were more confident about the availability and sufficiency of legal authorities than they were about policies and procedures for implementing them. Participants were also more likely to report the need for improvement in authorities, policies, and procedures in the private sector and at the local level than at the state level.
