“…Very few studies were conducted on armadillo’s species and only in Brazil. As reported in Table 1 , serogroup Autumnalis, Cynopteri, Hebdomadis and Pomona were isolated from kidneys of nine-banded armadillo ( Dasypus novemcinctus ) [ 88 , 95 ]. Also, a strain belonging to serogroup Pomona was isolated from the urine of a six-banded armadillo ( Euphractus sexcinctus ) [ 78 ].…”

Leptospirosis is a re-emerging worldwide zoonotic disease. Even though the primary serological test for diagnosis and surveying is the microscopic agglutination test (MAT), isolation remains the gold-standard test to detect Leptospira infections. The leptospirosis transmission is linked to maintenance and accidental hosts. In the epidemiology of Leptospira some serovar are strictly related to specific maintenance hosts; however, in recent years, the bacterium was isolated from an even wider spectrum of species. The aim of this review is to report the isolation of Leptospira strains in animals which could be recognized as “unconventional” hosts, analyzing studies from 1960 to 2020 that highlighted the Leptospira isolation. This scientific literature aimed to provide evidence of infection in several animal species including of the Carnivora, Didelphimorphia, Rodentia, Cetacea, Cingulata, Afrosoricida, Chiroptera and Primate orders, as well as in Reptilia and Amphibia classes. In conclusion, the spreading of Leptospira is attention-worthy because the infection could occur in all the animal species ranging in a specific area. Further screening and isolations are needed to collect all necessary data to gain a complete understanding of leptospirosis epidemiology and its modifications.

“…As ornamental animals, they are often globally transported to various zoos. Six-banded armadillos have been previously reported to be infected with Mycobacterium leprae (Frota et al 2012;da Silva Ferreira et al 2020) and Leptospira (Dalazen et al 2020), but little is known about their exposure to and/or infection due to other zoonotic pathogens. In the present study, we report a case of S. saprophyticus infection in six-banded armadillos.…”

Two six-banded armadillos (Euphractus sexcinctus) suddenly died in a zoo of Nanjing, Jiangsu province, China, after exhibiting weak breath, high temperature, and nasal bleeding. Autopsy revealed dark brown appearance and enlargement of the visceral organs and several granular white necrotic foci in the spleen and liver of the two armadillos. Histological analysis revealed serious congestion, haemorrhage, and multiple necrotic foci in the spleen and liver; lungs exhibited congestion. Moreover, the bacterium suspected to be responsible for the death of the armadillos was observed in the spleen and lung tissue samples. Several gram-positive cocci were observed in the contacting smears of liver tissue samples. Biochemical analysis revealed that the isolated bacterium was Staphylococcus saprophyticus and was designated as S.S NH2021; 16S rRNA and gap gene sequencing of the isolate provided similar findings. Strain S.S NH2021 was resistant only against penicillin. Moreover, the mice challenged with high load of the isolated bacterium died and exhibited histopathological changes similar to those observed in the armadillos. To the best of our knowledge, this is the first report on S. saprophyticus infection in armadillos. This study provides a reference for breeding and management of six-banded armadillos in zoos.

Two six‐banded armadillos (Euphractus sexcinctus) suddenly died in a zoo in Nanjing, Jiangsu Province, China, after exhibiting weak breath, high temperature and nasal bleeding. Postmortem examination revealed dark brown appearance and enlargement of the visceral organs, and several granular white necrotic foci in the spleen and liver of the armadillos. Histological analysis revealed serious congestion, haemorrhage and multiple necrotic foci in the spleen and liver; the lungs exhibited congestion. A bacterium suspected to be responsible for the death of the armadillos was observed in the spleen and lung tissue samples. Several Gram‐positive cocci were observed in impression smear of liver tissue samples. Biochemical analysis and 16S rRNA gene sequencing revealed that the isolated bacterium was Staphylococcus saprophyticus, and the strain was designated S.S NH2021. Strain S.S NH2021 was resistant only to penicillin. To the best of our knowledge, this is the first report of S. saprophyticus infection in armadillo.
