Seroprevalence and associated risk factors of leptospirosis in slaughter pigs; a neglected public health risk, western Kenya

Table 2 Seroprevalence of Leptospira serovars and serogroups by microscopic agglutination test (titer > 1:40) among 83 positive samples in Busia County, Kenya

Genomospecies	Serogroup	Serovar	Positive (n)	Prevalence (%)	95% CI
L. santarosai	Hebdomadis	Hebdomadis	1	0.4	0.01–2.2
L. interrogans	Bataviae	Bataviae	9	4.8	1.7–6.7
	Pomona	Pomona	2	0.8	0.1–2.8
	Australis	Lora	54	21.4	16.5–27.0
L. kirschneri	Grippotyphosa	Grippotyphosa	8	3.2	1.4–6.2
L. kirschneri	Icterohaemorrhagiae	Sokoine	9	3.6	1.7–6.7
L. borgpetersenii	Ballum	Kenya	13	5.2	2.8–8.7
L. borgpetersenii	Sejroe	Sejroe	1	0.4	0.01–2.2

Data are number of samples Leptospira positive (cut-off titer > 1:40), the serovar specific prevalence and their 95% confidence interval. MAT end-point titre was defined as the highest dilution at which ≥50% of leptospires were still agglutinate
