| The prevalence of anti-lentiviruses antibodies of small ruminants was investigated in goat herds in the city of Teresina, PI, Brazil. A seroepidemiological survey was conducted involving 480 animals, apparently healthy, belonging to six rural properties. The diagnostic test was the agar gel immunodiffusion (AGID), using antigens produced from cellular cultures infected with caprine arthritis encephalitis virus (CAEV Cork). Prevalences by gender and age were estimated considering sampling fractions for each farm. A general prevalence of 4.2%, was observerved, being 4.2% for females and 3.6% for males. Prevalences were higher among older goats. Regarding the breed standard, 23.5% were of the Anglo Nubian, 5.9% of the Boer, 35.3% Anglo Nubian x Boer... |

| A infecção por Brucella ovis é considerada uma das principais causas de epididimite e infertilidade em carneiros, resultando em falhas reprodutivas e perdas econômicas significativas em rebanhos ovinos ao redor do mundo. O estudo teve o objetivo de avaliar três testes sorológicos disponíveis para o diagnóstico da brucelose ovina por B. ovis, utilizando 181 soros ovinos. Amostras de soro provenientes de carneiros experimentalmente infectados foram coletadas ao longo de 192 dias pós-infecção (n=117) e durante o período pré-infecção (n=9). Adicionalmente, amostras de soro foram obtidas de ovinos provenientes de um rebanho livre para B. ovis (n=55). As técnicas de imunodifusão em gel de agar (IDGA), utilizando dois antígenos disponíveis comercialmente, e de... |

| This paper consists of a brief review on equine Infectious anemia added of the results of serological diagnosis of this infection performed at the Federal University of Santa Maria, RS, Brazil, between 1979 to 1990. A total of 7,035 serum samples were tested by the agar gel immunodiffusion test (Coggins test), to which 40 (0,57%) reacted positively. This percentage of positivity is lower than in other regions of Brazil, probably due to the lack of predisposing factors for equine infectious anemia virus spread, such as, a low density of blood-sucking insects in the South of Brazil and the seldom use of massive therapies and vaccinations in the region. |

| The purpose of this work was to evaluate two serological assays: double immunodiffusion (DI) and immunoblotting (IB) in immunodiagnosis of paracoccidioidomycosis (PCM). We evaluated by IB assay 23 sera samples from patients with clinical confirmation of PCM, all of them with negative DI results against culture filtrate from Paracoccidioides brasiliensis isolate 113. For IB, as well as for comparative DI assay, we employed soluble components of the cell wall outer surface (SCCWOS) from P. brasiliensis isolate 113 cultivated at 36°C in Fava-Neto's agar medium for 5 and 10 days. Among the 20 sera samples analyzed by DI, 13 (65%) were negative and 7 (35%) were positive against SCCWOS obtained on the 5th and 10th days. By IB assay, 95.4% and 100% of sera... |
