“…In BH-strain endemic areas, individuals with decompensated hepatosplenomegaly are commonly observed. In areas where patients are infected with the SJ strain, the commonly described clinical manifestations include the intestinal form with a slightly enlarged spleen [ 8 ].…”

The pathogenesis of three different Schistosoma mansoni strains from the Brazilian states of Minas Gerais (BH strain) and São Paulo (SJ and SD strains) was evaluated in experimentally infected mice. Observations of the most severe clinical cases among local patients treated (SD strain) in the city of Campinas (São Paulo, Brazil) formed the basis of this study. Mice were used as definitive hosts and were infected with cercariae from Biomphalaria tenagophila (SJ and SD strains) and Biomphalaria glabrata (BH strains). The parameters analyzed were as follows: number of S. mansoni eggs in mice feces; number of granulomas per tissue area in liver, spleen, lungs, pancreas, and ascending colon; measurements of hepatic and intestinal granulomas; number of adult worms; and measurements of trematode eggs. The comparison among the three strains indicated that the SD strain, isolated in Campinas, presented a higher worm recovery relative to the number of penetrating cercariae. In addition, when compared to the SJ and BH strains, the SD strain demonstrated similar pathogenicity to the BH strain, with a greater quantity of granulomas in the viscera, as well as larger granulomas and eggs. Furthermore, a greater quantity of trematode eggs was also shed in the feces.

“…In areas that are considered endemic for the BH strain, there are frequent cases of decompensated hepatosplenomegaly, which does not occur in regions where the SJ strain is present. Instead, almost all cases of infection with the SJ strain are asymptomatic, with the exception of rare cases of compensated hepatosplenomegaly [ 19 , 20 ]. In addition, adult worms and eggs of the BH strain are typically larger than those of the SJ strain [ 10 , 14 , 21 – 27 ].…”

The increased pathogenesis of the Schistosoma mansoni BH strain compared with the SJ strain has been attributed to the number of granulomas formed in experimental infections, which increase the mortality in definitive hosts. The aim of the present study was to investigate the development of granulomas around the eggs of the S. mansoni BH and SJ strains and to determine whether this host reaction was strain specific. Four experimental groups were analyzed. Two groups contained mice inoculated in the caudal vein with eggs from the S. mansoni BH or SJ strains and the other two contained mice that were infected with cercariae of the BH strain prior to being inoculated with eggs. The number of granulomas per tissue area in the lungs and liver, as well as the size of the granulomas, was analyzed to characterize the response to schistosome infection. The largest granulomatous responses were observed around eggs of the BH strain. Granulomas covered a larger area in the lungs of mice that were previously infected with cercariae and subsequently inoculated with eggs of the BH strain. These results indicated that specific granulomatous responses occurred following an infection with the BH and SJ strains of S. mansoni.

“…Sua história se confunde com a ascensão e queda econômica do próprio Vale do rio Paraíba do Sul, ou seja, inicialmente como rota de passagem para as regiões auríferas, depois o ciclo do café formando grandes fortunas e posteriormente, o declínio do café, a exaustão dos solos, a abolição da escravatura e finalmente, a construção da Rodovia presidente Dutra que a isolou, juntamente com várias cidades, das rotas comerciais (Santos, 2002).…”
