“…S. Saintpaul was responsible for a large foodborne outbreak of salmonellosis involving 1500 cases with 21% hospitalizations and two deaths in the United States (Barton et al, 2011). Gonose et al (2012) reported S. Blockley as the etiology of foodborne illness characterized by diarrhea, stomach cramp and headaches in three adult males in South Africa.…”

Invasive non-typhoidal salmonellosis characterized by gastroenteritis and bacteremia is endemic in sub-Sahara Africa. Most infections are foodborne with animals serving as asymptomatic carriers. We investigated Salmonella serovars and associated resistance genes in chicken meat using culture, minimum inhibitory concentrations and PCR amplification of resistance genes. Of 100 samples examined, 28 (28%) were Salmonella positive and spread across six serovars: Haifa (71.4%), Chomedey (7.1%), Saintpaul (7.1%), Kainji (7.1%), Derby (3.6%), and Blockley (3.6%). Antimicrobial resistance was observed to ciprofloxacin (85.7%), nalidixic acid (75.0%), sulfamethoxazole (67.9%), tetracycline (67.9%), trimethoprim (42.9%), gentamicin (35.7%), streptomycin (32.1%), ampicillin (10.7%), chloramphenicol (10.7%), kanamycin (7.1%) and florfenicol (3.6%). All isolates were susceptible to cefotaxime, ceftazidime and colistin, whereas 19 (67.9%) showed multidrug resistance to at least three antimicrobials. The predominant resistance type was Cip-Gen-Nal-Smx-Tet-Tmp detected in six (21%) isolates. Multidrug resistance of Salmonella serovars was high in the sampled chicken meat with resistance most observed against ciprofloxacin. This suggests possible horizontal transfer of plasmid-mediated quinolone resistance genes, which may compromise the clinical use of fluoroquinolones. Thus, improved hygiene and provision of adequate facilities at meat processing centers could help limit meat contamination and foodborne transmission of multi-resistant non-typhoidal Salmonella serovars from chickens to humans.

Human infections with Salmonella Blockley are uncommon, and cases described in the literature are usually gastrointestinal in origin. We report a case of an implantable cardioverter-defibrillator (ICD) infection in a 76-year-old Chinese man who presented with pain, redness, and warmth from the ICD pocket site, which later developed a sinus draining purulent material. S. Blockley was isolated from the wound and the patient underwent device removal and treatment with intravenous ceftriaxone. S. Blockley was cultured from the generator and the leads. The patient did not develop fever or bacteremia. This is, to the best of our knowledge, the first reported case of S. Blockley cardiac device infection.
