First detection of feline sporotrichosis (Sporothrix brasiliensis) at the zoonoses control service in Campo Grande, Mato Grosso do sul, Brazil.

Sporotrichosis is a traumatic mycosis affecting the skin or subcutaneous tissues caused by Sporothrix dimorphic fungus. The fungal complex includes several pathogenic species, out of which S. brasiliensis and S. schenckii are predominant in Brazil. In Mato Grosso do Sul (MS) state, the first human and animal cases were reported in 2016 in Corumbá and Ladário cities. Accordingly, we present the first occurrences of feline sporotrichosis detected in the state capital Campo Grande, MS, by the Zoonoses Control Service (ZCS) of the Municipal Public Health Department. The study included four allochthonous cases of feline sporotrichosis originating from Corumbá, MS, attended by the ZCS. All four cats presented classical clinical signs of sporotrichosis, as ulcerative nodular cutaneous lesions. Three slides tested positive by direct microscopy and PCR, followed by Sanger sequencing confirmed Sporothrix brasiliensis in two samples. The initial suspicion and diagnosis of feline sporotrichosis at the ZCS highlights the importance of accurate surveillance of sporotrichosis in non-endemic areas to enhance the capacity to prevent, detect and respond to emerging diseases in Campo Grande.

RETRACTED: Bovine Herpesvirus 5 promotes mitochondrial dysfunction in cultured bovine monocyte-derived macrophages and not affect virus replication.

This article has been retracted: please see Elsevier Policy on Article Withdrawal (https://www.elsevier.com/about/our-business/policies/article-withdrawal). This article has been retracted at the request of the Editors-in-Chief and Authors. Fig 1A is a duplicate of a figure that has already been published in da Silva SEL et al. Archives of Virology 2018;163:1043-1049; 10.1007/s00705-018-3704-2. These two papers report studies performed with cells from two different animal species (bovine cells for the Veterinary Microbiology paper and chicken cells for the Archives of Virology paper). The reuse of the same figure in the Veterinary Microbiology paper to describe cells that were supposed to be from a different species is thus inappropriate and also puts into question the reliability of the other results presented in this paper. In addition, the Editors-in-Chief have remaining concerns about the strong similarities of other data presented in the two papers. Even if these concerns were addressed, the re-use of any data has to be clearly indicated and appropriately cited. As such this article represents a misuse of the scientific publishing system. The scientific community takes a very strong view on this matter and apologies are offered to readers of the journal that this was not detected during the submission process.

Systemic oxidative stress in Suffolk and Santa Ines sheep experimentally infected with Haemonchus contortus.

The mechanisms responsible for the imbalance between oxidants and antioxidants in sheep infected with Haemonchus contortus are not well established. This study aimed to prove the hypothesis that oxidative stress occurring during infection by H. contortus varies according to breed, and that the parasite burden correlates with hypoalbuminaemia and anaemia. Thus, after deworming and confirming the absence of infection, two different sheep breeds, Suffolk (n = 15) and Santa Ines (n = 22), were orally inoculated with a single dose of 5,000 L3 of H. contortus. The egg counts per gram of faeces (EPG), packed cell volume (PCV) and concentrations of several plasma markers of oxidative stress (lipid peroxidation, albumin, uric acid, total bilirubin, total antioxidant capacity [TAC], total oxidant concentration [TOC] and the oxidative stress index [OSI]) were quantified before (control group) and during the experimental infection (28, 34 and 42 days post-inoculation). In both breeds, TOC increased at 28 days and TAC increased at 42 days. In Suffolk sheep, there was a positive correlation of EPG with oxidant components (28 days) and a negative correlation of EPG with PCV (42 days). In Santa Ines sheep, there was a positive correlation of EPG with bilirubin (r = 0.492; p = 0.020). H. contortus infection caused oxidative stress, which varied according to the breed. Parasite burden was not associated with hypoalbuminaemia, whereas there was a negative correlation with PCV. This research provides the first evidence that the antioxidant status contributes more to the resilience to H. contortus in Santa Ines sheep compared to Suffolk sheep.
