Xiphidiocercariae, aquatic larval stages of some trematodes are considered a potential instrument for biological control of mosquitoes. In this study we evaluated its natural occurrence in Campinas region and two places in Vale do Ribeira (Registro and Miracatu), Sao Paulo State. Snails were obtained from fresh water collections from September 1996 to February 1999. The species collected were Lymnaea columella, Physa marmorata, Biomphalaria tenagophila, Biomphalaria sp., Drepanotrema cimex, D. lucidum and Drepanotrema sp. Fasciola hepatica, xiphidiocercariae (Haematoloechidae) and echinostomatid cercariae were detected in the lymnaeids snails from Miracatu, SP. In the same locality were found planorbids snails parasitized by furcocercariae, echinostomatid cercariae and xiphidiocercariae. The xiphidiocercariae found in the planorbids were different from those obtained from lymnaeids. One Biomphalaria sp. infected with furcocercariae was found in Louveira, SP. In the ROSA place (Campinas, SP) an individual of Biomphalaria sp. and one of L. columella were found infected by the furcocercariae and echinostomatid cercariae, respectively. In the place UNI-I, in Campinas, one L. columella was infected by furcocercariae. Double infection in snails from Miracatu was also observed

Aedes albopictus larvae were exposed, either individually or in groups, to different concentrations of xiphidiocercariae of Haematoloechus sp. for parasitological studies. It was observed the acute lethal effect and some aspects of the host-parasite relationship, such as delay or progress in the host life cycle, the number and location of the metacercariae in the host, adult host malformations and the amount of metacercariae required to cause death. A delay in the cycle and a high mortality rate was in general observed. Inside the larvae, the metacercariae were found predominantly in the thorax, abdominal segments and in the head, along with a reduced number in the anal lobe and cervix. It was shown that in addition to the quantity of metacercariae present, their location in the larvae was also relevant in the determination of mortality and anomalies. Malformed adults developed from larvae containing from one to three metacercariae.

The metropolitan region of Recife, Brazil is endemic for Dirofilaria immitis and has an environment favorable to the development of Culex quinquefasciatus. The goal of this study was to evaluate the vector competence of the Cx. quinquefasciatus RECIFE population for D. immitis transmission. A total of 2,104 females of Cx. quinquefasciatus RECIFE population were exposed to different densities of D. immitis microfilariae blood meals, ranging from 1,820 to 2,900 mf/ml of blood, in a natural membrane apparatus. The results showed a variation between 92.3% and 98.8% of females fed. The exposure of the Cx. quinquefasciatus RECIFE population to different densities of microfilariae did not influence the mortality of the mosquitoes. Infective larvae from D. immitis were observed in the Malpighian tubules beginning on the 12th day, whereas larvae were observed in the head and proboscis beginning on the 13th day following infection. The vector efficiency index (VEI) presented by the mosquitoes ranged from 7.8 to 56.5. The data demonstrates that the Cx. quinquefasciatus RECIFE population has great potential for the transmission of D. immitis, as it allowed the development of the filarid until the infectious stage at the different densities of microfilariae to which it was exposed.

Rhipicephalus sanguineus sensu lato (s.l.) is one of the most widespread ixodid ticks and is a competent vector of several vector-borne pathogens of veterinary and medical concern. For instance, this tick species transmits nematodes of the genus Cercopithifilaria and protozoa of the genus Hepatozoon to carnivores, including dogs. Here we investigated the occurrence of Cercopithifilaria spp. and Hepatozoon spp. in a population of ticks collected from naturally infested dogs living in rural areas of Northeastern Brazil. From August 2016 to June 2017, 758 tick specimens (mean ticks per month = 68.9 ±71.4) were sampled from 75 dogs (mean ticks per dog = 10.11 ± 5.2) and dissected under a stereomicroscope in order to visualize Cercopithifilaria spp. larvae and Hepatozoon spp. oocysts and sporocysts. R. sanguineus s.l. was the only species collected, peaking in September (n = 273) and decreasing in February 2017 (n = 39). Different larval stages of Cercopithifilaria bainae were identified in 7 out of 758 (0.93%) ticks. In addition, 4 specimens (0.53%) were positive for oocysts and free sporocysts of Hepatozoon canis. The identity of both species of parasites was molecularly confirmed. These results account for the predominance of R. sanguineus (s.l.) in domestic dogs from rural locations of the study area, as well as for the presence C. bainae and H. canis in these tick populations.
