In silico and in vitro evaluation of primers for molecular differentiation of Leishmania species.

Leishmaniasis is a zoonotic disease caused by over 20 species of protozoan parasites of the genus Leishmania. Infection is commonly spread by sandflies and produces a wide spectrum of clinical signs and symptoms. Therefore, from an epidemiological and therapeutic standpoint, it is important to detect and differentiate Leishmania spp.

Growth Rate and Acceleration Analysis of the COVID-19 Pandemic Reveals the Effect of Public Health Measures in Real Time.

Ending the COVID-19 pandemic is arguably one of the most prominent challenges in recent human history. Following closely the growth dynamics of the disease is one of the pillars toward achieving that goal. We aimed at developing a simple framework to facilitate the analysis of the growth rate (cases/day) and growth acceleration (cases/day) of COVID-19 cases in real-time.

Seroprevalence rates of antibodies against Leishmania infantum and other protozoan and rickettsial parasites in dogs.

Canine visceral leishmaniasis (CVL) is caused by the protozoan Leishmania infantum, which infects dogs and humans in many regions of Brazil. The present study involved an indirect fluorescent antibody test (IFAT) to analyze L. infantum, Ehrlichia spp.

Usefulness of serological ELISA assay for Taenia saginata to detect naturally infected bovines.

Bovine cysticercosis, a cosmopolitan disease caused by Taenia saginata, leads to economic losses due to carcass devaluation at slaughter. Sanitary inspection at slaughterhouses, the routine diagnostic method in Brazil, lacks the necessary sensitivity to detect the mildly infected cattle that are typically encoutered in Brazil. In this study we have tested cattle sera from animals diagnosed as positive and negative by veterianry inspection for (1) anti-parasite antibodies using metacestodes antigens (T.

Visceral leishmaniasis in a captive crab-eating fox Cerdocyon thous.

Visceral leishmaniasis (VL) is a zoonotic disease with worldwide distribution. The crab-eating fox (Cerdocyon thous) is considered a wild reservoir of many zoonotical diseases, particularly VL. This study reported the presence of Leishmania infantum amastigotes in different organs of one captive C.

Taenia saginata: production and characterization of monoclonal antibodies against Taenia saginata metacestode antigens.

Cysticercosis is a major cause of economic loss in bovine production due to meat condemnation. Chemotherapy is being used in Brazilian cattle and a diagnostic test to improve the treatment program is desired. We produced monoclonal antibodies against crude (TAEB) and cyst fluid (TAEF) Taenia saginata metacestode antigens using immunized BALB/c mice.

[Parasitological, immunohistochemical and histopathological study for Leishmania chagasi detection in splenic tissues of dogs with visceral leishmaniasis].

The purpose of this work was a Canine Visceral Leishmaniasis--CVL study by parasitological direct examination of Leishmania (L.) chagasi (imprinting and histological), immunohistochemical test and histopathological analysis using spleen tissues from 34 dogs euthanized by the Zoonotic Disease Control Centre from Ilha Solteira, SP, Brazil. According to the clinical signs, the dogs were divided in three groups: asymptomatics (8 dogs), oligosymptomatics (17 dogs) and symptomatics (9 dogs).
