“…Other identified Bacillus species were B. clausii, B. foraminis, B. flexus, B. coagulans, and B. hortii. Other species were also identified in the tested products, such as Lactococcus garvieae, an emerging zoonotic pathogen that has been associated with endocarditis (Malek et al 2019), as well as a case of meningitis (Tandel et al 2017).…”

Previous studies have characterized bacterial communities in menthol versus non-menthol cigarettes. However, these studies evaluated commercial cigarettes, for which levels of chemical constituents are largely unknown, and therefore, could not assess the impact of varying nicotine and menthol concentrations on tobacco bacterial communities. To address this knowledge gap, we performed time-series experiments using SPECTRUM research cigarettes with varying nicotine and menthol levels. Cigarettes were incubated under three storage conditions for 14 days. Cigarette tobacco was then sub-sampled (n = 288), DNA extracted, and subjected to PCR amplification of the V3V4 region of the 16S rRNA gene, followed by Illumina HiSeq sequencing. Sequences were analyzed using QIIME and R. Incubation under varying conditions did not affect bacterial diversity. However, significant differences in bacterial communities were observed across varying nicotine concentrations in menthol and non-menthol products. For example, Pseudomonas spp. was negatively correlated with nicotine concentrations in menthol cigarettes. A significantly higher relative abundance of P. veronii and P. viridiflava was observed in menthols versus nonmenthols, while a significantly higher relative abundance of Bacillus foraminis and B. coagulans was found in non-menthols versus menthols. Additional bacteria (e.g., Staphylococcus spp., Jeotgalicoccus psychrophilus, and B. flexus) significantly changed in relative abundance between days 0 and 14. Our findings demonstrate that nicotine and menthol levels have a significant impact on the relative abundance of potential bacterial pathogens present in cigarettes. Future work is needed to demonstrate whether these tobacco-associated bacteria could be transferred to users while smoking, ultimately contributing to adverse respiratory impacts. Key points• Varying nicotine levels changes bacterial composition of research cigarettes.• Mentholation affects the tobacco bacterial microbiome.• SPECTRUM research cigarettes are dominated by Pseudomonas and Bacillus.

“…En 1955 se reportó el primer caso de endocarditis infecciosa por Lactococcus spp. en seres humanos, desde entonces en diferentes países se han comunicado casos de infecciones a nivel del tracto urinario, colecistitis acalculosa, meningitis, endocarditis en válvulas nativas y protésicas, prótesis articulares 4,5,6,7 . En nuestra búsqueda encontramos solo dos casos de compromiso multivalvular, en los cuales al menos una de las dos válvulas comprometida era protésica 8,9 .…”

Lactococcus garvieae es una causa inusual de bacteriemia. No existen guías diagnósticas y terapéuticas actuales disponibles para tratar las infecciones causadas por estos organismos. Con base en un informe de caso, proporcionamos una revisión de la literatura sobre bacteriemia causada por L. garvieae y destacamos los desafíos de diagnóstico y tratamiento de estas infecciones y las implicaciones para el manejo. Comunicamos el primer caso de bacteriemia por Lactococcus garvieae en Colombia.

“…Moreover, L. garvieae has been described as an opportunistic pathogen for humans, mainly affecting immunosuppressed patients, presenting co-morbidity factors such as age and concomitant diseases, though different cases have been reported in young and immunocompetent patients too [3,4]. It has mainly been isolated in cases of endocarditis [5,6], bacteriemia [3,7], peritonitis [3], liver abscess [8], osteomyelitis [9], spondylodiscitis [10], meningitis [11] and urinary tract infections [12,13]. Recently, a case of paediatric sepsis and the first description of recurrent throat infection in two children have been reported, both associated with multi-drug resistance [4,14].…”

Lactococcus petauri is a recently described species of the genus Lactococcus. It was reported as an etiological agent of piscine lactococcosis together with Lactococcus garvieae. L. garvieae was already described as an opportunistic pathogen in human infections, with a potential zoonotic role. This paper represents the first report of a human urinary tract infection caused by L. petauri. A 91-year-old man was admitted to the emergency department for a femur fracture consequent to a domestic accident. The fracture was reduced by surgery and a catheterized specimen urine culture revealed a high bacterial load sustained by Gram-positive cocci, identified by Vitek 2 compact as L. garvieae, and subsequently as L. petauri through Internal Transcribed spacer 16S-23S r-RNA amplification. The number of L. petauri infections in humans is expected to rise in the near future mainly due to diagnostic improvement. A dedicated survey on L. garvieae and L. petauri infections in humans should be performed to better understand their role as pathogens and as zoonotic agents.
