Sarcina, a new threat in the bariatric era

Emphysematous abomasitis in a lamb by bacteria of the Sarcina genus in Southern Brazil

“…In this report the diagnosis was based on morphological findings, and was not carried out the bacterial isolation. In previous studies in animals and humans the histology and cytology methods have been often used because bacteria of Sarcina genus have an unique morphological feature that is not found in other agents, as well as its extremely difficult isolation of which in most cases revealed negative results (DEBEY et al, 1996;VATN et al, 2000;EDWARDS et al, 2008;KUMAR et al, 2014;BHAGAT et al, 2015;SOPHA et al, 2015). In a previous study, 67 lambs with abomasal disease (abomasal bloat or rupture) and 45 healthy lambs were analyzed histopathologically, and the study found bacteria of the Sarcina genus in the abomasum of 53 lambs with abomasal disease and the absence of this bacteria in the abomasum of healthy lambs, demonstrating a possible causal association between bacteria from the Sarcina genus and gas accumulation in the abomasum.…”

A rare case of Sarcina ventriculi diagnosed on fine‐needle aspiration

“…Impaired gastric emptying could potentially lead to the growth of S ventriculi organisms, which are acid tolerant and use the retained food for fermentative metabolism . In addition to gastric biopsies, S ventriculi has been reported in cytology samples including brushing cytology of the esophagus and stomach and one case of FNA of pyloric ulcer . In our patient, delayed gastric emptying was a result of GOO due to pyloric strictures caused by prior ulcers.…”

“…1 This organism was first identified by Goodsir in 1842 in gastric contents. 2 Sarcina ventriculi is linked with conditions causing delayed gastric emptying and have been associated with abdominal pain, nausea, peptic ulcer, and diarrhea, 1,[3][4][5] and rarely life-threatening complications such as gastric perforation and emphysematous gastritis. 6,7 Sarcina ventriculi has also been reported in gastric specimens from asymptomatic patients.…”

PathogenicSarcinain urine

“…It is a Gram-positive, spore forming, obligate anaerobic coccus belonging to the Clostridiaceae family 4. The organism's peculiar arrangement in tetrads and octets is readily identified by light microscopy 5. There has been an exponential rise in the number of publications documenting Sarcina in the UGIT of human beings 1.…”
