BCG therapy remains at the forefront of immunotherapy for treating patients with superficial bladder cancer. The high incidence of local side effects and the presence of non-responder diseases have led to efforts to improve the therapy. Hence, we proposed that an auxotrophic recombinant BCG strain overexpressing Ag85B (BCG ∆leuD/Ag85B), could enhance the(More)
Natural products continue to be an invaluable resource of anticancer drug discovery in recent years. Propolis is known for its biological activities such as antimicrobial and antitumor effects. This study assessed the effects of Brazilian red propolis (BRP) on apoptosis and migration potential in human bladder cancer cells. The effect of BRP ethanolic(More)
Bacillus sphaericus produces a two-chain binary toxin composed of BinA (42 kDa) and BinB (51 kDa), which are deposited as parasporal crystals during sporulation. The toxin is highly active against Culex larvae and Aedes and Anopheles mosquitoes, which are the principal vectors for the transmission of malaria, yellow fever, encephalitis, and dengue. The use(More)
Visceral toxocariasis is a neglected zoonosis caused by Toxocara canis larvae in unusual hosts. In dogs, the definitive host, the infection occurs mainly through transplacental and transcolostral transmission. Studies on experimental models have shown that vertical transmission may result from acute infections. Considering that toxocariasis is characterized(More)
Neosporosis is a disease caused by the apicomplexan parasite Neospora caninum, which is closely related to Toxoplasma gondii. N. caninum infection represents an important cause of reproductive failure in sheep, goats, horses, and cattle worldwide. The diagnosis of neosporosis is based on the detection of pathogen-specific antibodies in animal sera or the(More)
BACKGROUND Caseous lymphadenitis (CLA) is an infectious disease that affects small ruminants and is caused by Corynebacterium pseudotuberculosis. This disease is responsible for high economic losses due to condemnation and trim of infected carcasses, decreased leather and wool yield, loss of sales of breeding stock and deaths from internal involvement.(More)
Neospora caninum is the etiologic agent of neosporosis, which leads to economic impacts on cattle industry. The reference method for serodiagnosis of neosporosis is the indirect fluorescent antibody test (IFAT). However, IFAT is laborious, expensive, and is not practicable in high throughput screening. In order to facilitate the serological diagnosis of(More)
Background Caseous lymphadenitis (CLA) is a disease caused by the bacteria Corynebacterium pseudotuberculosis which affects small ruminants such as sheeps and goats, leading to severe economic losses. The development of more sensitive and specific diagnoses showing effectiveness on asymptomatic animals is essential for disease's control. This study purposes(More)
The caseous lymphadenitis (CLA) is a common disease that affects ruminants around the world. The CLA is caused by gram-positive bacteria known as Corynebac-terium pseudotuberculosis, which is an intracellular facultative pathogen. In Brazil, the high prevalence occurs principally in northeast and southwest, where has the major herd of sheep and goat causing(More)
