Table 2. Detection of enteric colonization with third-generation cephalosporin-resistant Enterobacteriaceae in returned soldiers and previously reported detection rates in selected African and Asian countries (in alphabetic order).

Country	Resistant isolates in returned soldiers, n (%)	Percentage of resistant isolates within all analyzed Enterobacteriaceae in studies in the named countries (years of analysis)	References from previous studies
Central African Republic	0/1 (0)	12% of infections (2004–2006)	[19]
China	0/1 (0)	41% colonization (2011–2012) and 38–69% of infections (2011)	[20, 21]
Ethiopia	0/1 (0)	33% of infections (2003–2004)	[22]
Gabon	0/6 (0)	45% colonization (2012) and 15% of infections (2009–2012)	[5, 23]
Ghana	1/9 (11.1)	49% of infections (2011–2012)	[24]
Indonesia	0/3 (0)	2% colonization (2001–2002) and 36% of infections (2005)	[25, 26]
Morocco	0/1 (0)	43% colonization (2012) and 8% of infections (2010–2011)	[27, 28]
Nigeria	1/13 (7.7)	37% of infections (2013)	[29]
Pakistan	0/2 (0)	60% of infections (2009)	[30]
Senegal	0/5 (0)	4% of infections (2004–2006)	[31]
Tanzania	1/7 (14.3)	79% of infections (2011–2012)	[32]
Thailand	1/3 (33.3)	12% of infections (2004–2010)	[33]
Uganda	3/41 (7.3)	79% of infections (2011–2012)	[34]
Vietnam	0/1 (0)	40–49% of infections (2009–2011)	[35]

Interpretation has to be performed with care due to the very low numbers of assessed returned soldiers. A trend to very low colonization rates in the returnees is nevertheless detectable.
