L'ús d'esperma criopreservada en la inseminació artificial (IA) d'espècies d'interès productiu permet un major control sanitari i la creació de bancs de germoplasma d'alt valor genètic, entre d'altres avantatges. En el ...
El present treball analitza la morfologia espermàtica de l'ejaculat de Sus domesticus, la histologia del conducte epididimari i la qualitat de l'esperma epididimari. El material d'estudi prové de mascles reproductors porcins ...
Una soca de Lactobacillus salivarius resistent a la rifampicina, CTC2197, es va assajar com a probiòtic en pollastres, estudiant la seva capacitat de prevenir la colonització de Salmonella enteritidis C-114 en pollastres. ...
This thesis aims to develop a new non-invasive tool based on faecal bacterial markers for the early detection of colorectal cancer, which is capable of detecting precancerous lesions before the onset of clinical signs. ...
This doctoral thesis studies the abundance, diversity, seasonal dynamics and activity of Epsilonproteobacteria in a meromictic basin of Lake Banyoles during three year cycles. We applied a complementary array of molecular ...
In this PhD thesis Faecalibacterium prausnitzii populations of patients with gut disease and healthy individuals have been characterized. First, isolates from healthy volunteers have been phenotypically characterised, ...
En el presente estudio se analizan los efectos de los fotoperiodos ambientales de otoño e invierno y los fotoperiodos experimentales de 24, 12 y 0 horas de luz artificial sobre la calidad del semen de machos reproductores ...
ENG- The present doctoral thesis explores and compares the oral microbiome of ancient dental plaque from burial sites in the ancient Roman city of Tarraco (modern-day Tarragona) with dental plaque from present-day individuals. ...
Adherent-invasive Escherichia coli (AIEC) is a bacterium found in the intestine that can adhere to and invade intestinal epithelial cells and to survive and replicate inside macrophages. Although it has also been detected ...
Nowadays, the combination of the autotrophic nitrification together with heterotrophic denitrification is the most common process for N-removal in the WWTPs. However, when the C:N ratio is low, this two-step process does ...
Microbial electrosynthesis (MES) is engineered to use electric power and carbon dioxide (CO2) as the only energy and carbon sources in reductive bioelectrochemical processes for biosynthesis. This technology is conducted ...
La malaltia de Crohn és una malaltia inflamatòria intestinal crònica d'etiologia encara desconeguda. Actualment es pensa que hi participen factors genètics i immunològics que confereixen una susceptibilitat a l'hoste, i ...
Inflammatory bowel disease (IBD) is a group of immune-mediated chronic inflammatory intestinal conditions of multifactorial etiology. Unfortunately, there are still some gaps in its pathophysiology and, therefore, in its ...
This thesis shows how the metals of natural and anthropic origin change significantly the composition of the prokaryotic communities (mainly the composition of bacteria). The β-diversity is the most sensitive variable to ...
ENG- Intestinal microbiota, a diverse community of microorganisms residing in the gastrointestinal tract, plays a crucial role in digestion, nutrient absorption, and immune system regulation, thus influencing overall gut ...
The gut microbiota (GM) plays a pivotal role in the maintenance of gut homeostasis, and the pathogenesis of inflammatory bowel disease (IBD) which includes Crohn's disease (CD) and ulcerative colitis (UC). The degree of ...
The overuse of antibiotics has led to the selection of resistant strains. This thesis investigated the occurrence of antibiotic resistance genes (ARGs) in aquatic microbial communities influenced by anthropogenic activities. ...
Biogas is a highly recognized alternative to fossil fuels towards a sustainable energy production. Massive use of biogas depends on the removal of contaminants that may affect performance of processing equipment and energy ...
