Trop Anim Health Prod . 2021 Mar; 53(2):194. PMID: 33666800

At present, little is known regarding the prevalence of buffalo leptospirosis worldwide, especially with respect to which Leptospira strains may infect this animal species. Furthermore, most investigations into this disease...

Leptospira strains isolated from cattle in the Amazon region, Brazil, evidence of a variety of species and serogroups with a high frequency of the Sejroe serogroup

Barbosa Guedes I, de Souza G, Rocha K, Cavalini M, Damasceno Neto M, Castro J, et al.

Comp Immunol Microbiol Infect Dis . 2020 Nov; 74:101579. PMID: 33246243

In Brazil, there have been few leptospires isolated from cattle, especially in the Amazon, implying that the epidemiology of the disease in this region is still largely unclear. In a...

Leptospira transport medium (LTM): A practical tool for leptospires isolation

Barbosa Guedes I, Rocha K, Negrao M, de Souza G, Castro J, Cavalini M, et al.

J Microbiol Methods . 2020 Jun; 175:105995. PMID: 32593629

The isolation of Leptospira is challenging, since the bacteria of this genus are susceptible to adverse environmental conditions and may not remain viable for extend periods in urine samples. This...
