The growth capacity at 39 degrees C and 42 degrees C, production of hydrolytic enzymes and hemolytic activity of 21 clinical and reference strains of seven species of Candida spp were evaluated in vitro.Candida dubliniensis and Candida krusei demonstrated lower virulence potential and Candida albicans higher potential.

Slaughterhouse environments are prone to microbial contamination, influenced by factors like set-up, size and area as well as disinfection practices. Thus, effective control measures are crucial to prevent the spread of pathogens and their contaminant genes (antimicrobial resistance genes and virulence factors) throughout the food chain. In the present study, we assessed the microbial contamination in environmental surfaces of three slaughterhouses located in the Jaén province (Spain).

It was a general belief that drug resistance in Mycobacterium tuberculosis (Mtb) was associated with lesser virulence, particularly rifampicin resistance, which is usually produced by mutations in the RNA polymerase Beta subunit (RpoB). Interestingly, this kind of bacterial mutations affect gene transcription with significant effects on bacterial physiology and metabolism, affecting also the bacterial antigenic constitution that in consequence can produce diverse immune responses and disease outcome. In the present study, we show the results of the Mtb clinical isolate A96, which is resistant to rifampicin and when used to infect BALB/c mice showed hypervirulence, apparently by rapidly polarization of the Th2 immune response through early and high production of IL-4.

Vulvovaginal candidiasis (VVC) is one of the most common infections caused by . VVC is characterized by an inadequate hyperinflammatory response and clinical symptoms associated with colonization of the vaginal mucosa. Compared to other host niches in which can cause infection, the vaginal environment is extremely rich in lactic acid that is produced by the vaginal microbiota.

Birds have evolved seasonal adaptations in multiple aspects of the innate and adaptive immune systems. Seasonal immunological adaptations are crucial for survival in harsh environmental conditions and in response to increased prevalence of acute and chronic diseases. Similar to other vertebrates, birds exhibit remarkable plasticity in cytokine production, chemotaxis, phagocytosis and inflammation across the year.
