| a general survey of blood and tissue parasites of some rodents in arbil province, iraq. | in a survey of blood and tissue parasites from 233 mice and rats, consisting of 105 specimens of house mice (mus musculus), 99 black rats (rattus rattus), and 29 norway rats (rattus norvegicus), collected from different localities of arbil province, northern iraq, trypanosoma lewisi was found in 7 (7.07%) of 99 r. rattus and in 5 (17.86%) of 29 r. norvegicus, while trypanosoma musculi was found in 4 (3.80%) of 105 m. musculus and this is the first record of this trypanosome from rodents in iraq. ... | 1988 | 3052538 |
| natural babesia infection sought in black and norway rats trapped in five egyptian governorates. | babesiosis is a protozoal disease caused by members of the genus babesia transmitted by the ixodid ticks. it is a parasite of various mammalian hosts as bovine (b. bovis), equine (b. equi), rodent (b. microti), canine (b. canis) and others. human cases of babesiosis have been reported from several countries including egypt. it is now well established that man may become infected (fulminating or subclinical) with several species of babesia without prior splenectomy. in this paper, a total of 398 ... | 1993 | 8376851 |
| schistosoma japonicum in the black rat, rattus rattus mindanensis, from leyte, philippines in relation to oncomelania snail colonies with reference to other endoparasites. | this study examined the prevalence of schistosoma japonicum infections in field rats, rattus rattus mindanensis, according to different trapping locations. between october 1995 and january 1996, traps were set in the municipality of palo, leyte, philippines to determine the correlation of rats infected with schistosomiasis to the proximity of the intermediate snail host, oncomelania hupensis quadrasi, colonies. of the 22 rats that were caught within a snail colony, 21 (95.5%) were positive for s ... | 1999 | 10774707 |
| infection by trypanosomes in marsupials and rodents associated with human dwellings in ecuador. | small mammals trapped in domestic and peridomestic environments of rural ecuador were screened for trypanosome infection by direct microscopy and hemoculture. identification of species of trypanosomes was then performed by morphological characteristics and by polymerase chain reaction (pcr) assays. of 194 animals collected, 15 were positive for infection (7.73%). eight (4.12%) were infected with trypanosoma cruzi (1 of 33 didelphis marsupialis; 7 of 61 rattus rattus). eleven r. rattus (18.03%) h ... | 2006 | 17304802 |
| molecular survey of rodent-borne trypanosoma in niger with special emphasis on t. lewisi imported by invasive black rats. | invading rodent species can harbor parasites with potential transmission to native rodents and/or humans. to investigate trypanosomes prevalence in rodents, the spleen of 76 rodents from niger identified by their karyotype was used as a dna source for trypanosoma detection using a newly developed qpcr assay. of the invasive black rat, rattus rattus, 71% (10/14) were pcr positive as well as 6% (4/62) of native african rodents. sequences of ~400bp of the ssu rdna gene identified phylogenetically c ... | 2010 | 21126503 |
| some field and laboratory studies on rattus rattus subspecies and rattus norvegicus in two egyptian governorates of different ecological characters. | both damietta and qualyobia governorates were examined for the seasonal activities of rattus species and subspecies and their natural infection with trypanosoma lewisi. the common domestic rodents identified were rattus r. alexandrinus, r. r. frugivorus and rattus norvegicus. they were common all the year round except in winter for r. norvegicus in damietta. gravid females of the three rodent species, were identified in damietta in summer, in addition to autumn for r. norvegicus only. in qualyob ... | 2002 | 12512813 |
| pcr identification of trypanosoma lewisi, a common parasite of laboratory rats. | trypanosoma (herpetosoma) lewisi is a trypanosome of the sub-genus herpetosoma (stercoraria section), parasite of rats (rattus rattus and rattus norvegicus) transmitted by fleas. t. lewisi has a stringent species specificity and cannot grow in other rodents such as mice. rats are infected principally by oral route, through contamination by flea faeces or ingestion of fleas. trypanosoma lewisi infections in rat colonies can interfere with research protocols and fleas of wild rats are often the so ... | 2002 | 12234387 |
| [prevalence of protozoa infections in synanthropic rodents in valdivia city, chile]. | in order to determine the prevalence of infection by blood and intestinal protozoa in 57 synanthropic rodents from valdivia city, a study was carried out in the period march-september 1986. the group of rodents studied was constituted by 31 mus musculus, 19 rattus rattus and 7 oryzomys longicaudattus, being 42 males and 15 females. diagnostic forms of protozoa were found in 70.2% of the investigated animals. the presence of five species of enteroprotozoa and one species of hemoflagelate was dete ... | 1995 | 8762669 |
| the parasites obtained and bacteria isolated from house rats (rattus rattus linnaeus, 1758) caught in human habitations in ibadan, nigeria. | a total of 169 house rats were killed in different households distributed within five localities of ibadan. a wide range of parasites were encountered. the flea, ceratophylus fasciatus was the commonest ectoparasite found. trichostrongylus columbriformis eggs were the commonest nematode and hymenolepis diminuta the only cestode. escherichia coli was the commonest bacterium found. the incidence of helminthiasis, especially h. diminuta, was generally high among rats trapped in the villages and the ... | 1981 | 7037672 |
