1. Establishment of a Pathogenicity Index for Mice to Pasteurella multocida Strains Isolated from Poultry and Swine
ABSTRACT Fowl cholera is a contagious disease that results from infection by the bacterium Pasteurella multocida. This microorganism is extensively distributed among animal species, but little is known regarding it’s pathogenesis and specificity to various hosts. Many studies using pathogenicity evaluation methods are subjective and difficult to quantify b

2. CBCT-based evaluation of integrity of cortical sinus close to periapical lesions
The purpose of the present study was to test the applicability of cone beam computed tomography (CBCT) to evaluate the integrity of the cortical sinus close to periapical lesions. Two observers analyzed samples of 64 alveoli of first molar roots in macerated swine maxillas prepared with perchloric acid to simulate periapical lesions. The specimens were evalu

3. Development and validation of a genotype 3 recombinant protein-based immunoassay for hepatitis E virus serology in swine
Hepatitis E virus (HEV) is classified within the family Hepeviridae, genus Hepevirus. HEV genotype 3 (Gt3) infections are endemic in pigs in Western Europe and in North and South America and cause zoonotic infections in humans. Several serological assays to detect HEV antibodies in pigs have been developed, at first mainly based on HEV genotype 1 (Gt1) antig

4. Standardization of enzyme immunoassay (ELISA) for serology, detection and quantification of porcine circovirus type 2 / Padronização de ensaios imunoenzimáticos (ELISA) para sorologia, detecção e quantificação do circovírus suíno 2
Porcine circovirus 2 (PCV-2) is the major causative agent of postweaning multisystemic wasting syndrome (PMWS) and is associated with different syndromes that affect the swine. The term PCVAD (Porcine circovirus associated diseases) was introduced in 2006 to gather many diseases. Since serological studies are essential for monitoring the virus, the aim of th

5. Sensibilidade e especificidade do perfil estral para o diagnóstico de ovulação em fêmeas suínas / Sensitivity and specificity of estrus profile for ovulation diagnosis in female swine
fêmea suína é poliéstrica anual, tem a duração aproximada de 21 d (dias), com variação entre 17-25 d. O processo de recrutamento da população de folículos ovulatórios inicia-se com o declínio nas concentrações plasmáticas de progesterona que caracterizam o final da fase luteal do ciclo estral, embora o sinal endócrino específico para este r

6. Sorologic evaluation of swine cysticercosis by ELISA using antigens: total extract and scolex from Cysticercus cellulosae and vesicular fluid from Cysticercus longicollis / Avaliação sorológica da cisticercose suína pelo ELISA utilizando os antígenos: total e de escólex de Cysticercus cellulosae e líquido vesicular de Cysticercus longicollis
Swine cysticercosis is a disease caused by the Taenia soliums metacestodes, called Cysticercys cellulosae (Cisticerci). This disease is largely spread around the world and is more frequent in countries where swine meat consumption is high and sanitary conditions are poor, as in developing countries. Cysticercosis is harmful to the raising of the swine beca

7. Highly Sensitive PCR Assay for Routine Diagnosis of African Swine Fever Virus in Clinical Samples
This work provides a novel, highly sensitive, hot start PCR method for rapid and specific detection of African swine fever virus (ASFV) that can be used as a routine diagnostic test for ASFV in surveillance, control, and eradication programs. A confirmatory test of the specificity of this method based on restriction endonuclease analysis was also developed.

8. Characterization of pseudorabies virus antibody responses in young swine after infection and vaccination by using an immunoglobulin M antibody capture enzyme-linked immunosorbent assay.
An immunoglobulin M (IgM) antibody capture enzyme-linked immunosorbent assay (MACELISA) was developed for the detection of pseudorabies virus (PRV)-specific IgM antibody in swine sera because false-positive reactions frequently occurred when sera from older swine were tested with an indirect IgM enzyme-linked immunosorbent assay. Monoclonal mouse anti-swine

9. Diagnostic Evaluation of a Real-Time Reverse Transcriptase PCR Assay for Detection of Classical Swine Fever Virus
A fluorogenic-probe hydrolysis (TaqMan)-reverse transcriptase (RT) PCR for classical swine fever virus (CSFV) was evaluated for diagnostic sensitivity and specificity by using clinical samples obtained from the Dominican Republic, where the disease is enzootic. The sensitivity of this test, using nasal swab samples taken from both symptomatic and asymptomati

10. New method of antibody detection by indirect immunoperoxidase plaque staining for serodiagnosis of African swine fever.
An indirect immunoperoxidase plaque-staining method was developed for detecting antibody to African swine fever virus infection. In both sensitivity and specificity, the test was comparable to indirect immunofluorescence. Because it has all of the desirable features of the indirect immunofluorescence test and may also be readily used for testing large number

11. Amino Acid Residues Contributing to the Substrate Specificity of the Influenza A Virus Neuraminidase
Influenza A viruses possess two glycoprotein spikes on the virion surface: hemagglutinin (HA), which binds to oligosaccharides containing terminal sialic acid, and neuraminidase (NA), which removes terminal sialic acid from oligosaccharides. Hence, the interplay between these receptor-binding and receptor-destroying functions assumes major importance in vira

12. Monoclonal antibodies specific for African swine fever virus proteins.
We have obtained 60 stable hybridomas which produced immunoglobulins that recognized 12 proteins from African swine fever virus particles and African swine fever virus-infected cells. Most of the monoclonal antibodies were specific for the three major structural proteins p150, p72, and p12. The specificity of some monoclonal antibodies for the structural pro
