Abstract

Bats are economically important animals and serve as food sources in some African regions. They can be colonized with theStaphylococcus aureuscomplex, which includesStaphylococcus schweitzeriandStaphylococcus argenteus. Fecal carriage ofS. aureuscomplex in the straw-colored fruit bat (Eidolon helvum) has been described. However, data on their transmission and adaptation in animals and humans are limited. The aim of this study was to investigate the population structure of theS. aureuscomplex inE. helvumand to assess the geographical spread ofS. aureuscomplex among other animals and humans. Fecal samples were collected fromE. helvumin Obafemi Awolowo University, Ile-Ife, Nigeria. The isolates were characterized by antimicrobial susceptibility testing,spatyping and multilocus sequence typing (MLST). Isolates were screened for the presence oflukS/lukF-PV and the immune evasion cluster (scn, sak, chp) which is frequently found in isolates adapted to the human host. A Neighbor-Joining tree was constructed using the concatenated sequences of the seven MLST genes. A total of 250 fecal samples were collected and 53 isolates were included in the final analysis. They were identified asS. aureus(n= 28),S. schweitzeri(n= 11) andS. argenteus(n= 14). Only oneS. aureuswas resistant to penicillin and another isolate was intermediately susceptible to tetracycline. Thescn, sak, andchpgene were not detected. Species-specific MLST clonal complexes (CC) were detected forS. aureus(CC1725),S. argenteus(CC3960, CC3961), andS. schweitzeri(CC2463). STs ofS. schweitzerifrom this study were similar to STs from bats in Nigeria (ST2464) and Gabon (ST1700) or from monkey in Côte d'Ivoire (ST2058, ST2072). This suggests host adaptation of certain clones to wildlife mammals with a wide geographical spread in Africa. In conclusion, there is evidence of fecal carriage of members ofS. aureuscomplex inE. helvum.S. schweitzerifrom bats in Nigeria are closely related to those from bats and monkeys in West and Central Africa suggesting a cross-species transmission and wide geographical distribution. The low antimicrobial resistance rates and the absence of the immune evasion cluster suggests a limited exposure of these isolates to humans.

Attention Score in Context

Attention Score in Context

This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 01 March 2018.
All research outputs
#17,932,482
of 23,025,074 outputs
Outputs from Frontiers in Microbiology
#17,430
of 25,149 outputs
Outputs of similar age
#314,628
of 446,086 outputs
Outputs of similar age from Frontiers in Microbiology
#428
of 558 outputs
Altmetric has tracked 23,025,074 research outputs across all sources so far. This one is in the 19th percentile – i.e., 19% of other outputs scored the same or lower than it.
So far Altmetric has tracked 25,149 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 6.3. This one is in the 22nd percentile – i.e., 22% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 446,086 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 24th percentile – i.e., 24% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 558 others from the same source and published within six weeks on either side of this one. This one is in the 18th percentile – i.e., 18% of its contemporaries scored the same or lower than it.
