“…During foodborne S. enterica and E. hirae infection, pathogens can pass the gut epithelial cell lining and translocate to extra-intestinal organs like the spleen, liver, and bladder [ 3 ]. Moreover, it has been shown that both bacteria are models of UTIs related to gastrointestinal infections and other physiological disorders [ 3 , 6 , 7 , 11 , 12 ]. Therefore, our attention was focused on the effect of xyloglucan plus gelose following salmonella and enterococcus oral infection in the bladder.…”

Acute infectious gastroenteritis (GE) and urinary tract infection (UTI) are common diseases and are normally perceived as mild and limiting illnesses. Xyloglucan is a natural plant polymer with protective barrier properties, also known as “mucosal protectors”, which is the main ingredient of medical devices developed for the management of different diseases, such as gastrointestinal diseases, urinary tract infections, or respiratory allergic diseases. The aim of this study was to evaluate the protective effect of xyloglucan in association with gelose (also called agar) in an experimental model of bacterial GE and UTI in rats. Two kinds of infection were induced by oral administration of Salmonella enterica and Enterococcus hirae for three days. Two days before the bacterial administration, preventive oral treatment with xyloglucan + gelose (10 mg/kg + 5 mg/kg) was performed daily until the seventh day. Twenty-four hours after the last treatment, rats were sacrificed and urinary tracts and intestines for different analysis were collected. The results showed that xyloglucan plus gelose was able to reduce intestinal morphological changes (p < 0.05 for both), tight junctions (TJ) permeability (p < 0.001 for both), and neutrophil infiltration (p < 0.05 for both) induced by bacterial infections, highlighting its barrier proprieties. Moreover, the compound reduced the number of bacterial colonies in the urinary tract favoring elimination by feces. The results obtained in the present study suggest that the protective barrier properties of xyloglucan plus gelose allow the prevention of GE and UTI in models of infections in rats.

“…Moreover, although it is a rare cause, several authors have demonstrated a growing frequency of Salmonella spp. isolated in urine samples from UTIs with an unrecognized cause or related to immunodeficiency or a urological abnormality [ 6 , 7 , 8 ]. Over the past decade, Enterococcus spp.…”

“…In a cohort single-center study that reviewed all cases of NTS urinary tract infections, 27% of patients had isolated symptomatic NTS urinary tract infection without gastroenteritis or Salmonella isolated from a fecal sample. These individuals were found to have a higher rate of underlying lower urinary tract malignancies, as well as higher rates of diabetes and underlying immunosuppressive states [23].…”

Background We report the first case of canine Salmonella meningoencephalomyelitis and second case of canine Salmonella bacteriuria, as well as the first reported case of Salmonella enterica subspecies houtenae in a dog. Case presentation Immunosuppressive treatment in a dog for a relapse of steroid-responsive meningitis and arteritis (SRMA) allowed for the opportunistic establishment of a bacteremia with Salmonella enterica subsp. houtenae, ultimately causing meningoencephalomyelitis and subclinical bacteriuria. The bacterial infections were treated with a four-month course of amoxicillin; clinical treatment success was determined by serial negative urine cultures and lack of clinical signs correlated to the meningoencephalomyelitis. Conclusions Both the bacteriuria and meningoencephalomyelitis represented opportunistic infections in a dog immunosuppressed for SRMA. The clinical course of this infectious meningoencephalitis emphasizes the importance of differentiating relapse of initial disease from opportunistic infection occurring in a compromised central nervous system. The novel Salmonella species identified in this case acts as a reminder that infectious disease diagnostics should not be curbed by anecdotal prediction of routine pathogenic suspects.

La infección del tracto urinario es un importante problema de salud. La infección urinaria causada por microorganismo del genero Salmonella es rara y se asocia a enfermedades inmunosupresoras. Presentamos el caso de una paciente con antecedente de Diabetes Mellitus que presenta molestias urinarias y urocultivo positivo a Salmonella no tiphy. Con el avance de la medicina y el aumento de procesos inmunospuresores puede verse con mayor frecuencia este tipo de patologías.
