“…All 70 Salmonella isolates were resistant to amoxicillin/clavulanic acid, streptomycin and neomycin (Table ). This agrees with previous reports in which antibiotics have only limited effectiveness against Salmonella strains isolated from sources as diverse as vegetables, carrots, tomatoes, meat, dairy products, wild animals, compost, soils, wastewater, potable water and human feces . However, 65 of the 70 isolates were susceptible to chloramphenicol and nalidixic acid, while 60 and all 70 isolates were sensitive to ciprofloxacin and ceftriaxone respectively (Table ).…”

“…In addition, strains isolated from cow manure and human feces in Ethiopia and Nigeria have been reported sensitive to ciprofloxacin, a result due to the almost total absence of ciprofloxacin use in these countries . Chloramphenicol sensitive strains have been isolated from vegetables . In contrast, ciprofloxacin‐ and ceftriaxone‐resistant Salmonella strains have been isolated in China and the USA .…”

The presence of multidrug-resistant Salmonella in vegetables is a significant public health concern. Multidrug-resistant Salmonella strains were isolated from raw tomatoes purchased in public markets in Mexico and challenged with roselle Hibiscus sabdariffa calyx extracts, sodium hypochlorite and acetic acid. On tomatoes, the extracts caused a greater reduction in the concentration of antibiotic-resistant Salmonella strains than sodium hypochlorite and acetic acid. Roselle calyx extracts are a potentially useful addition to disinfection procedures of raw tomatoes in the field, processing plants, restaurants and homes.

“…A loopful from each of the enriched broths were streaked onto Hektoen Enteric Agar (HEK) (Merck), Salmonella-Shigella Agar (Merck) and Xylose Lysine Deoxycholate Agar (XLD) (Merck), Agar plates were incubated at 37 °C for 18 to 24 h. About 5 characteristic colonies of Salmonella were randomly picked from each plate and inoculated into Triple Sugar Iron Agar (TSA) (Merck) and Lysine Iron Agar (LIA) (Merck) slants. Each culture showing presumptive-positive TSI and LIA results were maintained on Tryptone Soya Agar (TSA)(Merck) (Salleh et al, 2003;Lertworapreecha et al, 2013).Gram reaction and oxidase test were carried out on the presumptive isolates. Suspected Salmonella colonies were confirmed by biochemical reactions using Analytical Profile Index (API) 20E strips (bioMérieux, Marcy-L'Étoile France).…”

ABSTRACT:The aim of the study was to isolate Salmonella from fresh cabbage and spinach vegetables, determine antimicrobial resistance and biofilm formation of the isolates. Spinach and cabbage farm vegetables were found to harbour Salmonella. A total of eighty-two Salmonella isolates were recovered from both vegetables and subjected to antimicrobial reactions. Salmonella isolate showed sensitivity against the aminoglycoside and quinolones.Isolates from cabbage showed ≥ 80% susceptibility to nalidixic acid and ciprofloxacin and an average of 72% susceptibility was exhibited against gentamicin and ofloxacin. Also, isolates from spinach vegetable demonstrated excellent sensitivity against chloramphenicol (94%), nalidixic acid (90%) and ofloxacin (82%). Variable resistant patterns was observed for tetracycline (58%: 47%), ampicillin (55.5%: 31.4%), erythromycin (58.1%: 62.7%), streptomycin (64.5%: 76.5%), cephalothin (35.5%: 39.2%) against isolates from cabbage and spinach respectively. The assessment of biofilm formation by Salmonella on microtitre plate showed that all Salmonella isolates were able to form biofilms. Isolates from cabbage were mainly strong producer 15(48.3%), while 11(35.5%) of the isolates were moderate producers and 6(16.1%) weak producer. On the other hand, 28(54.9%) of Salmonella isolates from spinach vegetable were moderate producer, 12(23.5%) weak producer and 11(21.5%) strong producer. The finding of this study shows that cabbage and spinach is potential host for the transmission of Salmonella to humans or other animals. The ability of the isolates to form biofilm reveals the potential of the isolates to persist on the vegetable and the pathogenic status of the isolates as well as ability to resist antimicrobial chemotherapy. © JASEM http://dx
