3.3 Genetic patterns in Brazil
According to databases sought, Brazil owns the major quantity of studies, a total of 16/30 articles. For this reason, it is suitable to describe the genetic patterns found specificly in this Country, among its five geographical regions (North, Northeast, Middle-West, Southeast and South). Genotypes are listed in Table 4 by region, and illustrated in Figure 3 . One of the articles studied chickens from ParĂ¡ (North) and Rio Grande do Sul (South).
A total of 259 isolates were identified in Brazil, classified in 107 different genotypes. 1 (0,4%), 5 (2,0%), 1 (0,4%), 142 (56,1%), 1 (0,4%) and 103 (40,7%) were from Clonal Type I, II, III, Atypical, Mixed and Not defined, respectively. Overall, genotypes ToxoDB #1, #2, #6, #7, #8, #10, #11, #13, #14, #16, #19, #21, #24, #26, #30, #32, #36, #44, #48, #53, #55, #59, #60, #61, #62, #64, #65, #75, #88, #94, #95, #97, #98, #108, #109, #111, #116, #120, #122, #140, #146, #152, #162, #163, #175, #206, #213, #214, #215, #216, #235, #248, #251, #252, #253, #273, #274, #277, #278, #279 and #280 were identified. ToxoDB #59 was the most frequent genotype.
