Changes in lipid abundance are associated with disease progression and treatment response in chronic <em>Trypanosoma cruzi</em> infection
Background: Chagas disease, caused by the parasite Trypanosoma cruzi, is a zoonosis that affects more than seven million people. Current limitations on the diagnosis of the disease hinder the prognosis of patients and the ...
Pseudomonas guineae sp.nov, a novel psychrotolerant bacterium from an Antarctic environment
Two Gram-negative, cold-adapted, aerobic bacteria, designated strains M8T and M6, were isolated from soil collected from the South Shetland Islands. The organisms were rod-shaped, catalase- and oxidase-positive and motile ...
Seroepidemiological study of <em>Leishmania infantum</em>, <em>Toxoplasma gondii</em>and <em>Dirofilaria immitis</em> in pet ferrets (<em>Mustela putorius furo</em>) in Spain
Ferrets are susceptible to infections with <em>Leishmania infantum</em>, <em>Toxoplasma gondii</em>, and <em>Dirofilaria immitis</em>; however,</p><p>epidemiological data on these infections are limited in Europe. A total ...
Higher-order organisation of extremely amplified, potentially functional and massively methylated 5S rDNA in European pikes (Esox sp.)
Background Pikes represent an important genus (Esox) harbouring a pre-duplication karyotype (2n = 2x = 50) of economically important salmonid pseudopolyploids. Here, we have characterized the 5S ribosomal RNA genes (rDNA) ...
