Persistent infection with Strongyloides venezuelensis in the Mongolian gerbil (Meriones unguiculatus) Byeong-Kirl Baek, In-Soo Whang, M. Khyrul Islam, Byeong-Soo Kim, Ibulaimu Kakoma Korean J Parasitol 2002;40(4):181-186. Published online December 30, 2002 DOI: https://doi.org/10.3347/kjp.2002.40.4.181 Abstract PDF To examine the fate of Strongyloides venezuelensis, Mongolian gerbils (Meriones unguicalatus) were orally infected with 1,000 L₃ larvae per animal. Altogether, 50 gerbils divided into 5 groups of 10 each were monitored for a period of 570 days to document the kinetics of faecal egg output, adults worm population, morphological development, fecundity, and hematological changes including peripheral blood eosinophilia. This study chronicled a life long parasitism of S. venezuelensis in the gerbil host, and showed that S. venezuelensis infection was quite stable throughout the course of infection and the worms maintained their normal development as evidenced by their body dimension. A progressive loss of body condition of the infected gerbils was observed as the level of infection advanced. However, no detectable pathological changes were observed in the gastrointestinal tract. The present findings indicate that an immunocompetent host, such as the Mongolian gerbil, can serve as a life long carrier model of S. venezuelensis if the worms are not expelled within 570 days after infection.

Published online September 30, 2000 DOI: https://doi.org/10.3347/kjp.2000.38.3.187 Abstract PDF To determine association of grassland with parasitic diseases of livestock in Bangladesh, the 'Tracer' animals (two cow calves and two goats) were released for a month in a grassland used for communal grazing of livestock near school premise in Kanthal, Trishal, Mymensingh, Bangladesh. After slaughtering of the tracer animals, their gastrointestinal tract examination revealed six species of nematode and one cestode. The nematode species were Haemonchus contortus, Trichostrongylus axei, Mecistocirrus digitatus, Oesophagostomum spp., Trichuris spp. and Bunostomum sp. The cestode was one of the genus Moniezia. With this preliminary study, grasslands are thought to be one of the main sources of gastrointestinal parasitic diseases of livestock in Bangladesh.

Published online June 30, 1999 DOI: https://doi.org/10.3347/kjp.1999.37.2.101 Abstract PDF Rats were immunized through an initial infection with 1,000 filariform larvae (L₃) of Nippostrongylus brasiliensis and after complete expulsion of worms they were challenged with 1,000 L₃ of Strongyloides venezuelensis to investigate whether cross-resistance developed against a heterologous parasite. Nippostrongylus brasiliensis-immunized rats developed a partial cross-resistance against S. venezuelensis migrating larvae (MSL₃) in the lungs and adult worms in the small intestine. The population of MSL₃ in the lungs were significantly lower (P<0.05) in immunized rats (22.0 ± 7.4) compared with controls (105.0 ± 27.6). The populations of adult worms, egg output and fecundity were initially decreased but from day 14 post-challenge they did not show any significant difference between immunized and control rats. However, the length of worm in immunized rat was revealed as retardation. Peripheral blood eosinophilia was significantly decreased (P<0.05) on day 7 post-challenge and then gradually increased, which peaked on day 42 post-challenge when most of the worms were expelled. These results suggest that peripheral blood eosinophilia is strongly involved in the worm establishment and expulsion mechanisms.

Khyrul Islam, Kiku Matsuda, Jin-Ho Kim, Byeong-Kirl Baek Korean J Parasitol 1999;37(1):13-19. Published online March 31, 1999 DOI: https://doi.org/10.3347/kjp.1999.37.1.13 Abstract PDF The effects of in vitro culture methods on morphological development and infectivity of Strongyloides venezuelensis filariform larvae (L₃) to rats were investigated. A significantly higher body length was observed in L₃ from filter paper culture (597.3 ± 32.2 ?m) than those in fecal (509.9 ± 35.0 ?m) and nutrient broth culture (503.3 ± 31.0 ?m) (P<0.05). Larval infectivity was assessed by exposing rats to 1,000 L₃ from each culture and worms were recovered from the lungs and small intestines. Recovery rate of these worms did not show any significant difference. A significantly greater body length of adults was recorded in those corresponding to the L₃ harvested from filter paper (2,777.5 ± 204.4 ?m) and nutrient broth culture (2,732.5 ± 169.8 ?m) than those corresponding to the L₃ obtained from fecal culture (2,600.5 ± 172.4 ?m) (P<0.05). Although worm fecundity and EPG counts differed among culture methods but worm burdens and course of infection did not. These findings suggest that the methods of cultures have a significant effect on the morphological development of the larvae to the L₃ stage, but do not influence the infectivity to rats.
