The study’s objective was to determine the epidemiological, clinical, and laboratory characteristics of cases of invasive salmonellosis and the antibiotic susceptibility profile of salmonella isolates (2013-2017), in a series of cases of patients with Salmonella spp. isolated from secretions and/or body fluids with or without positive stool culture (n=70). For the evaluation of antibiotic susceptibility, the first isolate was considered in all cases of salmonellosis (n=168). The highest frequency of cases occurred between 0 to 4 years (14.3%) and over 65 years (24.3%). The most frequent symptoms were fever (66.1%), diarrhea (40.7%), and sensory issues (40.7%). Human immunodeficiency virus (HIV) infection was the most common co-morbidity (42.4%). The frequency of susceptibility was 83.3% to ceftriaxone, 78.8% to cotrimoxazole, and 75.0% to chloramphenicol. Only 50.8% were susceptible to ciprofloxacin. We concluded that invasive salmonellosis was more common in young children and the elderly and that HIV infection was the most common comorbidity.
