Goat and sheep production in the semi-arid northeast of Brazil has shown great economic potential. However, health problems can compromise the productivity of these animals.

Given the scarcity of studies about the occurrence of these diseases, the aim of the present study was to analyze the serological diagnosis of anti- Brucella and anti-lentivirus antibodies among small ruminants in municipalities located in the Brazilian states of Bahia and Pernambuco.

The samples were collected from local slaughterhouses and dairy farms. In total, serum samples from animals in slaughterhouses and dairy herds were collected. The buffered acidified antigen test goats and agarose gel immunodiffusion test sheep were used to detect anti- Brucella abortus and B.

With anti-CAEV antibodies, seropositivity rates of 4. None of the animals goats or sheep were positive for anti- B. Results of the present study confirmed the presence of the CAE virus in the meat and dairy herds studied, although the prevalence was low. Natural infection by B. Direct tests are required to diagnose ovine brucellosis.

The Brazilian economy has benefitted from the steep growth of goat and sheep production in several Brazilian states. However, the production and productivity of these animals can be affected by several factors, particularly nutrition, general management conditions, and sanitary conditions. Viruses and bacteria cause diseases that threaten the development of the goat and sheep industries in Brazil.

This virus can lead to sub-clinical inflammation in one or more organs, mainly affecting the joints, nervous system, mammary glands, and respiratory system BLACKLAWS et al. Brucellosis is another disease with great economic significance. It has been recorded all over the world and its etiology involves facultative intra-cellular bacteria of the genus Brucella species-specificof which six are the most widely recognized CASTRO et al.

An infected animal is the main source of infection for humans and other animals, and is typically a result of direct contact with secretions, fomites and contaminated food CARNEIRO et al.

Goats and sheep although less common in the latter may manifest systemic signs including fever, apathy, weight loss, diarrhea, mastitis, lameness, and orchitis in males SMITH, Given the scarcity of studies on the occurrence of these diseases, particularly brucellosis, the aim of the present study was to conduct a serological diagnosis of the circumstances of these diseases among small ruminants in municipalities located in the Brazilian states of Pernambuco and Bahia.

The study region comprised the bipole of Petrolina Pernambuco and Juazeiro Bahiaas well as the municipality of Valente Bahiathe main characteristics of which are the semi-arid climate and the native caatinga vegetation. The collections were made at slaughterhouses and on rural milk production properties.

Blood samples were collected from goats and sheep at the municipal slaughterhouse in Petrolina PE and from sheep in the LAMM slaughterhouse in Juazeiro BAfor a total of animals from slaughterhouses. Sampling of milk-producing animals was performed at 15 goat-milk production properties in the municipality of Valente-BA, totaling dairy animals. Non-probabilistic convenience sampling was used, as described by Thrusfield In order to perform the collections, the animals were restrained and submitted to antisepsis of the jugular vein with iodized alcohol.

The blood samples a volume of approximately 10 mL were collected through jugular venipuncture using disposable hypodermic needles 40 x 12 mm. In order to obtain the serum, this volume remained in the tube until the compete retraction of the blood clot.

After the distribution of the test, control, and antigen in the agarose gel, these serum were incubated at room temperature in a humid chamber for 72 h.

The serum were considered positive when a line of precipitation formed between the central well antigen and the serum being tested, exhibiting its identity with the formation of a line between the positive control serum and ca;rinos antigen ARRUDA et al. The buffered acidified antigen technique goats and the agarose gel immunodiffusion test sheep were used to assess anti- Brucella abortus and B.

The serum and antigen were then capirnos for 2 min using circular movements, and the results were analyzed in an indirect light box.

The serum that exhibited agglutination were designated as collected from reagent animals, whereas those without agglutination were from non-reagent animals BRASIL, Descriptive statistics, the distribution of the relative and absolute frequencies of the results obtained in the serological tests, were used. In the survey of anti-CAEV antibodies, bruceelose seropositivity rate caaprinos 4.

The current literature contains very few serological surveys that sought to diagnose CAEV among animals destined for slaughter, because this disease is more commonly correlated with dairy herds and intensive management systems used in milk production. Similar results were obtained by Oliveira et al.

The concordance between these studies may be due to their similarities, because they were both conducted in slaughterhouses in the same state. In the Northeast region of Brazil, it is common for farmers to keep dairy animals and those specialized in meat production together, thereby favoring the transmission of the disease.

In addition, on many sites, animals are raised with a dual zootechnical purpose, which favors the dissemination of the agent. A seropositivity rate of 2.

A study by Castro et al. The low prevalence of positive czprinos in the present study may have been caused by the acquisition of these animals in suitable locations. In addition, fairs and expositions in the region examined in this study currently demand proof of negativity for CAEV, which helps to maintain the sanitary status of herds.

Thus, molecular techniques of viral detection have been used to provide an early diagnosis of the disease. Bruvelose of these techniques is polymerase chain reaction PCRthe aim of which is in vitro amplification of nucleic acids, thereby enabling the attainment of thousands of copies of a specific DNA sequence without the need for a bodily response such as the production of antibodies ANDRIOLI et al. Regarding the survey of anti- B. However, a recent study by Pinheiro Junior et al.

The same authors reported prevalence rates of 0. The concordance of the findings could reflect similarities observed in the studies with respect to caprinis management conditions, the number of animals assessed and the region studied. In the survey of B. In a study conducted in the Agreste capeinos of Pernambuco, Pinheiro Junior et al.

csprinos The low seroprevalence found could have been due to the small number of animals in each of the bruceloes assessed and the extensive breeding system, which decreased the probability of infection. The presence of the CAE virus could be confirmed in the herds studied, although the prevalence was low. This result is significant, given that studies of this type of herd meat are caprinow.

Preventive sanitary capprinos must be implemented in these types of production systems. Conversely, natural infection with B. Seropositivity was recorded for B.
