“…From 138 R. norvegicus captured in Salvador, Brazil, 56.5% were parasitized by C. hepaticum (Galvão, 1976), and in the city of São Paulo, 59% from 205 rodents (R. norvegicus and R. rattus) were also parasitized (Chieffi et al, 1981). Records of the nematode were also recently registered in the city of Belém, in Eastern Amazon (Moreira et al, 2013).…”

The occurrence of the black rat, Rattus rattus , in major Brazilian cities has increased in the recent years. To evaluate if the efforts of public rodent control have been reaching the species in the city of São Paulo, a survey was conducted in flooding areas using live trapping before and after implementation of the control program. Captures were carried out from 2009 to 2011, and animals were evaluated for their risk of zoonosis transmission. The number of R. rattus captured after control did not differ from the number of animals captured before the control program in the Spring/Summer season, but, in the Autumn/Winter season, effective control was observed. Low infestations of Ctenocephalides felis (Siphonaptera) and Echinolaelaps echidninus (Acarina) were observed, and antibodies against Leptospira spp. were detected in just 1 of 65 serum samples. Ten out of 18 serum samples were sororeactive for Vaccinia virus, suggesting contact between R. rattus and the pathogen Calodium hepaticum (= Capillaria hepaticum ) (Nematoda) was found in the liver of 73.4% of captured R. rattus. In conclusion, R. rattus may not be effectively controlled by the rodent Control Program in the city of São Paulo, and represents a threat to human health, justifying permanent environmental management and educational programs.

“…Although previously published studies show that the prevalence of C. hepatica in certain rodent species, tends to be high (between 56.5 and 89.3%) 5 , 7 , 20 , 31 , the prevalence of C. hepatica infection appears to be low among residents of the studied area and among rodents that live close to their dwellings.…”

Introduction: Hepatic capillariosis, caused by Capillaria hepatica (Calodium hepaticum) (Bancroft, 1893), Travassos, 1915 (Nematoda, Trichinelloidea, Capillariidae), is a common zoonosis in rodents but is rare in humans. Seventy-two cases in humans have been reported worldwide since the first case was described by MACARTHUR in 192417,27. This study aimed to determine the prevalence of Capillaria hepatica in humans and rodents in an urban area of Porto Velho, the capital of Rondônia, in Brazil. Methods: After conducting a census of the area, 490 residents were randomly selected, and, after signing a term of consent, provided blood samples that were screened for anti-Capillaria hepatica antibodies. Simultaneously, rats were captured to assess the prevalence of this parasite in rodents by histopathological examination in liver sections. Results: A prevalence of 1.8% was found among residents who had specific antibodies at a dilution of 1:150, indicating exposure to parasite eggs; 0.8% of the subjects also had positive titers at a dilution of 1:400, indicating true infection. The prevalence in rats was 2%. Conclusions: The prevalence of infection with this parasite among humans and rats was low. While the prevalence encountered among humans was within the limits reported in the literature, the prevalence among rodents was much lower.

PREVALENCE OF Calodium hepaticum (SYN. Capillaria hepatica) IN Rattus norvegicus IN THE URBAN AREA OF RIO DE JANEIRO, BRAZIL

The nematode Calodium hepaticum (syn. Capillaria hepatica) is a zoonotic helminth found mainly infecting rats. It was studied the prevalence of C. hepaticum infection in Rattus norvegicus in an urban area of Rio de Janeiro (Brazil), with low urban planning and sanitation. The presence of C. hepaticum was identified through visible yellowish-white lesions in liver tissue and histological analyses. The total prevalence of infection was 45%, with no significant differences between sex and age. The presence of infected rodents near the peridomestic area poses substantial risk to human health.
