“…Core-genome phylogeny confirmed the placement of C. marimammalium within the order Lactobacillales , where it forms a unique clade, which is consistent with previous 16S gene phylogenetic analyses (1). Preliminary reconstruction using Pathway Tools v.16 (11) revealed an overall reduced metabolic network with a particularly limited capacity for de novo amino acid biosynthesis compared to other closely related organisms.…”

“…Catellicoccus marimammalium was first isolated from the carcass of a porpoise that had succumbed to severe enteritis and peritonitis along the coast of Scotland (1). A low-G+C Gram-positive catalase-negative facultative anaerobe, C. marimammalium is closely related to, but biochemically distinct from, other genera within the order Lactobacillales (1).…”

Recently, 16S rRNA gene-based surveys and species-specific PCR assays have shown high host distribution and an abundance of species closely related to C. marimammalium in different waterfowl (2–4).…”

Avian feces contaminate waterways but contribute fewer human pathogens than human sources. Rapid identification and quantification of avian contamination would therefore be useful to prevent overestimation of human health risk. We used subtractive hybridization of PCR-amplified gull fecal 16S RNA genes to identify avian-specific fecal rRNA gene sequences. The subtracters were rRNA genes amplified from human, dog, cat, cow, and pig feces. Recovered sequences were related to Enterobacteriaceae (47%), Helicobacter (26%), Catellicoccus (11%), Fusobacterium (11%), and Campylobacter (5%). Three PCR assays, designated GFB, GFC, and GFD, were based on recovered sequence fragments. Quantitative PCR assays for GFC and GFD were developed using SYBR green. GFC detected down to 0.1 mg gull feces/100 ml (corresponding to 2 gull enterococci most probable number [MPN]/100 ml). GFD detected down to 0.1 mg chicken feces/100 ml (corresponding to 13 Escherichia coli MPN/100 ml). GFB and GFC were 97% and 94% specific to gulls, respectively. GFC cross-reacted with 35% of sheep samples but occurred at about 100,000 times lower concentrations in sheep. GFD was 100% avian specific and occurred in gulls, geese, chickens, and ducks. In the United States, Canada, and New Zealand, the three markers differed in their geographic distributions but were found across the range tested. These assays detected four important bird groups contributing to fecal contamination of waterways: gulls, geese, ducks, and chickens. Marker distributions across North America and in New Zealand suggest that they will have broad applicability in other parts of the world as well. Contamination from gulls, Canada geese, ducks, and other birds negatively impacts water quality (5, 16, 24, 33a, 49, 56). Their feces are sources of fecal coliforms, enterococci, and Escherichia coli, and their presence is correlated with elevated fecal indicator bacteria (FIB) and beach closures (2,22,23,38). Pathogenic E. coli and Campylobacter, Salmonella, Giardia, and Cryptosporidium spp. occur in bird feces (11,18,19,42) and can infect domestic poultry and humans (27, 41) and contaminate shellfish (1). Bird feces are also a source of antibiotic resistance genes (34,39,50). Recently, because of avian influenza, concerns have risen about pathogen movement due to bird migration (8,10,17,28,30).Although pathogens occur in bird feces, exposure to bird feces is considered less harmful to humans than exposure to other sources of fecal contaminants, especially that of humans (43, 51). For example, molecular evidence indicates that genotypes of certain parasites in birds, such as Giardia and Cryptosporidium, are host adapted and cannot cross-infect among different hosts (20, 57). The relative human health risks of bird and human fecal contamination will be more amenable to measurement once reliable methods are developed to distinguish them quantitatively. The ability to rapidly identify and quantify fecal contamination from birds will improve our ability to estimate human health risk from conta...

“…This finding is interesting, as C. marimammalium was recently described as a new group of low-GϩC gram-positive bacteria isolated from a porpoise and a gray seal (21). This group is part of the Bacilli class and specifically belongs in the Enterococcaceae family, which houses the genera Enterococcus, Melissococcus, Tetragenococcus, and Vagococcus.…”

In spite of increasing public health concerns about the potential risks associated with swimming in waters contaminated with waterfowl feces, little is known about the composition of the gut microbial community of aquatic birds. To address this, a gull 16S rRNA gene clone library was developed and analyzed to determine the identities of fecal bacteria. Analysis of 282 16S rRNA gene clones demonstrated that the gull gut bacterial community is mostly composed of populations closely related to Bacilli (37%), Clostridia (17%), Gammaproteobacteria (11%), and Bacteriodetes (1%). Interestingly, a considerable number of sequences (i.e., 26%) were closely related to Catellicoccus marimammalium, a gram-positive, catalasenegative bacterium. To determine the occurrence of C. marimammalium in waterfowl, species-specific 16S rRNA gene PCR and real-time assays were developed and used to test fecal DNA extracts from different bird (n ‫؍‬ 13) and mammal (n ‫؍‬ 26) species. The results showed that both assays were specific to gull fecal DNA and that C. marimammalium was present in gull fecal samples collected from the five locations in North America (California, Georgia, Ohio, Wisconsin, and Toronto, Canada) tested. Additionally, 48 DNA extracts from waters collected from six sites in southern California, Great Lakes in Michigan, Lake Erie in Ohio, and Lake Ontario in Canada presumed to be impacted with gull feces were positive by the C. marimammalium assay. Due to the widespread presence of this species in gulls and environmental waters contaminated with gull feces, targeting this bacterial species might be useful for detecting gull fecal contamination in waterfowl-impacted waters.
