A case of polyparasitism in an 8-year-old female cat from Southern Brazil is reported. Among the described clinical signs, both gurltiosis and lagochilascariasis are of rare occurrence, being categorized as neglected diseases. The diagnosis of feline crural parasitic paraplegia was established through clinical signs, necropsy lesion observations, and the presence of Gurltia paralysans in histological sections of the spinal cord.

The redescription of has brought to focus Scanning Electron microscopic evidence of evolutionary consequence. The intestinal caeca, ventriculus and ventricular appendix of family Anisakidae; ventriculus and ventricular appendix of family Raphidascaridae; and along with it, post-cloacal collarette of family Physalopteridae in worms recovered from coral-reef associated fish hosts at '' island, evidently confirmed that the characters of as many as three families were encountered in . The selective adaptation of these specific characters exhibited significant evolutionary trend, and indeed these could radiate connecting link features of Raphidascarididae.

Co-evolutionary adaptation of hookworms with their mammalian hosts has been selected for immunoregulatory excretory/secretory (E/S) products. However, it is not known whether, or if so, how host immunological status impacts the secreted profile of hematophagous adult worms. This study interrogated the impact of host Signal transducer and activator of transcription 6 (STAT6) expression during the experimental evolution of hookworms through the sequential passage of the life cycle in either STAT6 deficient or WT C57BL/6 mice.

The present study aims to assess the performance of different molecular targets using various matrices of samples for the detection of Uncinaria stenocephala (US) in hookworm infected dogs. To this end, the DNA extraction was performed on the following matrices of samples: (i) larvae of US obtained from experimentally infected dogs with US with different larvae counts per microliter (µl); (ii) pure US eggs suspension in distilled water with different egg counts per µl; (iii) spiked dog fecal samples with different US eggs per gram (EPG) of feces; (iv) feces from dogs naturally infected with hookworm eggs; (v) fecal suspension with hookworm eggs recovered from the FLOTAC apparatus. All the samples were tested with four different PCR protocols targeting specific regions for the detection of both hookworms US and AC as follows: Protocol A (ITS1, 5.
