This survey evaluates, after more than a decade since the last epidemiological survey, the current situation and trend of CE in sheep of the highly endemic island of Sardinia (Italy). From 2012 to 2018, out of a total of 1416 sheep, 65.3% were found positive for CE. Cyst fertility has increased slightly from 10.3% in 2006 (Scala et al. 2006) to 11.7% in the present survey (χ2 = 1.07; P = 0.30018) with a peak of 14.0% in the province of Sassari. Overall, 6815 hydatids were found and classified as sterile (26.2%), fertile (14.4%), caseous (5.3%), or calcified (54.1%) based on their morphology. All isolates were identified as E. [https://www.selleckchem.com/products/azd-1208.html selleck chemicals] granulosus sensu stricto (former G1/G3, strains). Results shown as the implementation of new European Council Regulations and in particular of 21/2004 that established a system for the individual identification and tracking of sheep could be a step forward towards a better control of animal movement, preventing illegal slaughtering on the island as well as in other countries experiencing similar problems. Even if at first sight the general situation of Sardinia regarding CE seems a little better compared with the past, our findings indicate that in some Provinces the epidemiological situation is not improved since 2006.Lice from family Echinophthiriidae are of the few insects that have successfully colonized marine environment living as ectoparasites of pinnipeds, i.e., sea lions, seals, and the walrus. They have developed unique adaptations to cope with the amphibious lifestyle of their hosts. Because eggs do not survive underwater, lice could only reproduce when their host remains on pack ice enough time. Consequently, lice generations per year are limited by host haul-out behavior. The objective of this work is to study the effect of host sex and age class, and the annual variation on the prevalence and mean abundance of Antarctophthirus lobodontis in crabeater seals from the Antarctic Peninsula. During three consecutive field-seasons, we collected lice from 41 crabeater seals (23 females, 16 males, 2 indeterminate, being 24 adults, and 17 juveniles). We investigated this effect on the prevalence and mean abundance by a generalized linear model formulation in a Bayesian framework. According to the lowest Deviance Index Criterion model, sex host does not affect prevalence nor mean abundance. We found that juveniles present greater abundance and prevalence than adults, possibly due to foraging habits. They spent more time on the ice than adults in groups of dozens of animals. This behavior would favor both egg development and lice transmission. We do not find adult females with lice, which suggests that transmission of A. lobodontis should be horizontal. The high mean abundance of lice in 2014 could be associated with an unusual increase in Lobodon carcinophaga population, probably related to the pack-ice availability and zooplankton abundance.This is the first study showing an in vivo microautophagy upregulation by Leishmania infantum in dogs. Both Leishmania amastigotes and promastigotes were detected in the cytoplasm of many professional and nonprofessional phagocytic cells of popliteal lymph node of three dogs suffering from chronic cutaneous leishmaniasis. Ultrastructurally, parasites appeared to be wrapped by lysosomes and/or multivesicular bodies. Neither phagophores nor double-membraned vacuoles consistent with autophagosomes were observed. Transcription factor EB (TFEB), a key factor involved in lysosome biogenesis, showed a statistically significant increase in the total component when examined by western blot in samples from leishmaniotic dogs compared with samples from healthy dogs. Instead, phosphorylated TFEB showed unmodified expression levels both in leishmaniotic and healthy dogs. Furthermore, Hsc70 and endosomal sorting complex required for transport (ESCRT)-I, which are known to play a role in microautophagy, showed no variation in expression levels both in diseased and healthy animals. Vps4A/B, an evolutionary conserved ATPase responsible for ESCRT-I complex disassembly and MVB maturation, was statistically significantly overexpressed in lymph nodal samples from leishmaniotic dogs. Bag3 was downregulated in diseased dogs whereas CHIP, p62, and LC3-II did not show any variation in expression levels. The altered expression profile of Bag3 suggested an altered interaction of Bag3 with Hsc70 and CHIP, which usually form a molecular complex involved in autophagosome-lysosome pathways. Ultrastructural and molecular findings suggested that the microautophagy pathway is upregulated in lymph nodes of dogs suffering from a chronic natural infection by Leishmania infantum.To enhance specific or total sophorolipids (SLs) production by Starmerella bombicola for specific application, mutant library consisting of 106 mutants from 7 batches was constructed via atmospheric and room-temperature plasma (ARTP). When compared to the wild strain, 11, 36 and 12 mutants performed increases over 30% in lactonic, acidic or total SLs production. Genetic stability investigation showed that 8, 7, and 4 mutants could maintain the improved SLs production capacity. Mutants of A6-9 and A2-8 were selected out for enhanced specific SLs and total SLs production in fed-batch cultivation in flask. Without optimization, A6-9 obtained the highest reported lactonic SLs production of 51.95 g/l and A2-8 performed comparable acidic and total SLs production of 68.75 g/l and 100.33 g/l with all the reported stains. The structural composition of the obtained SLs was analyzed by HPLC and LC/MS, and the results confirmed the enhancement of SLs and certain SL components. These mutants would be important in industrial applications because the production and purification costs of SLs could be greatly reduced. Besides, the acquisition of these mutants also provided materials for the investigation of regulation mechanism of SLs biosynthesis for further genetic engineering of S. bombicola. Furthermore, critical micelle concentration (CMC), minimum surface tension (STmin) and hydrophilic-lipophilic balance (HLB) of the SLs obtained from the wild and mutant strains were also examined and compared. These results demonstrated the feasibility of obtaining SLs with different properties from different strains and the high efficiency of mutation breeding of S. bombicola by ARTP.
