Mycobacterium leprae in Nine-Banded Armadillos (Dasypus novemcinctus), Ecuador.

We found Mycobacterium leprae, the most common etiologic agent of Hansen disease or leprosy, in tissues from 9 (18.75%) of 48 nine-banded armadillos (Dasypus novemcinctus) collected across continental Ecuador. Finding evidence of a wildlife reservoir is the first step to recognizing leprosy zoonotic transmission pathway in Ecuador or elsewhere.

A unique presentation of subcutaneous infection: A case report of a diagnostic challenge.

Introduction: is a yeast-like anamorphic rare fungus commonly found in tropical areas. This case report is the first one located in South America.

Case Report: A 67-year-old patient presented with a 5-year history of right foot pain attributed to foot trauma while at sea 5 years prior.

The impact of detailed history taking: a case report of pediatric pulmonary and hepatic hydatid disease from Ecuador.

Background: Echinococcosis is a uncommon condition in pediatric patients, and encompasses alveolar and cystic forms, predominantly affecting the lungs and liver. Transmission occurs primarily through zoonotic means, such as the contamination of water and food by infected dog and other canid feces. Diagnosis can be challenging due to nonspecific symptoms that often mimic pneumonia.

Hepatitis B Virus (HBV) Genotypes in an Ecuadorian Population: A Preliminary Study.

Chronic hepatitis B virus (HBV) infection affects 257-291 million people worldwide. The World Health Organization reported 890,000 HBV-related deaths in 2019, higher than reported previously. There are 10 HBV genotypes (A-J) subdivided into several subgenotypes that differ considerably by geography.

Identification of the Genotypes Circulating in the Ecuadorian Population Infected with the Hepatitis C Virus (HCV).

Introduction: The hepatitis C virus (HCV) is responsible for 1.5 million new infections, and around 290 thousand deaths worldwide. 15 to 30% of the patients that go into a chronic phase of the disease will develop cirrhosis or hepatocellular carcinoma within 20 years and is the leading etiology for liver transplantation.
