Services on Demand Journal. However, health problems can compromise the productivity of caprinod animals. Current therapy in theriogenology, 2. Results of the present study confirmed the presence of the CAE virus in the meat and dairy herds studied, although the prevalence was low. Given the scarcity of studies about brucelos 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.

Vut In addition, on many sites, animals are raised with a dual zootechnical purpose, which favors the dissemination of the agent. The blood samples a volume of approximately 10 mL were collected through jugular venipuncture using disposable hypodermic needles 40 x 12 mm.
Retroviral Infections in Sheep and Goats: Transmission of small ruminant lentiviruses. One 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. 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 buffered acidified antigen test goats and agarose gel immunodiffusion test sheep were used to detect anti- Brucella abortus and B. How to cite this article.
The serum and antigen were then mixed for 2 min using circular movements, and the results were analyzed in an indirect light box. The samples were collected from local slaughterhouses and dairy farms. A study by Castro et al. 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, 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. 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.
Natural infection by B. Regarding the survey of anti- B. Viruses and bacteria cause diseases that threaten the development of the goat and sheep industries in Brazil. 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.
Routes of transmission and consequences of small ruminant lentiviruses SRLVs infection and eradication schemes. None of the animals goats or sheep were positive for anti- B. Services on Demand Journal. Results of the present study confirmed the presence of the CAE virus in the meat and dairy herds studied, although the prevalence was low. Serological response of sheep and goats to conjunctival Brucella melitensis Rev.
January 21, ; Accepted: 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.
However, a recent study by Pinheiro Junior et al. Preventive sanitary measures must be implemented in these types of production systems. Non-probabilistic convenience sampling bfucelose used, as described by Thrusfield The low prevalence of positive animals in the present study may have been caused by the acquisition of these animals in suitable locations.
However, health problems can compromise the productivity of these animals. Bruxelose 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 vaprinos these diseases among small ruminants in municipalities located in the Brazilian states of Pernambuco and Bahia.
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. A seropositivity rate of 2. In total, serum samples from animals in slaughterhouses and dairy herds were collected. Causes and diagnosis of abortion in brucelosse. Goats and sheep although less common in the latter may manifest systemic signs including fever, apathy, weight loss, diarrhea, mastitis, lameness, and orchitis in caprinso SMITH, 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.
Goat and sheep production in the semi-arid northeast of Brazil has shown great economic potential. In a study conducted in the Agreste region of Pernambuco, Pinheiro Junior et al. In the survey of B. The collections were made at slaughterhouses and on rural milk production properties.
The buffered acidified antigen technique goats and the agarose gel immunodiffusion test sheep were used to assess anti- Brucella bruceloose and B. The same authors reported prevalence rates of 0. Most Related.
