Summary of the number of pathogen and host species and genes within version 3.0 of PHI-base

Host/Entry type	Vertebratea	Planta	Fungal	Insect
Host species	8	51	3	3
Genes in totalb	339	588	3	8
Pathogenicity genes	50	97	0	0
Virulence genes	243	241	3	6
Effector genes	0	64	0	0
Anti-infective targetc	5	19	0	0

^aTotal entry numbers for each of the top three vertebrate and plant-attacking species are 353 and 288, respectively (the same gene can be tested for function on different hosts from different kingdoms).

^bSome genes were tested on more than one host, some genes have no specific host.

^cThirteen anti-infective targets are broad-range and have no specific host associated.
