ABSTRACT
A fifty-four year old woman underwent colonoscopy due to symptoms of altered bowel habit and weight loss. There was a malignant looking lesion at her rectosigmoid junction [Fig. 1a] which was confirmed histologically to be a moderately differentiated adenocarcinoma. Although the blood results were normal, her CT scan and MRI [Fig 2a] showed an apple core lesion at rectosigmoid junction which was deemed to be Stage IIIC (T4aN2aM0)

In Rangoon and vicinity Suncus murinus comprises almost 20% of the small mammal population with almost equal load of mesostigmatid mites compared to murine rodents. Suncus murinus was infected by four species of laelapids, out of which L. myonyssognathus seems to infest more on urban S. murinus. The infestation of the free living Androlaelaps or Hypoaspis species is higher on the rural shrews while the Cheyletus species is higher on the urban than the rural S. murinus.

Examination of 536 female mesostigmatid mites of 177 samples collected from Bandicota bengalensis in Rangoon, Burma revealed 6 species present: Laelaps echidnina, L. nuttalli, L. myonyssognathus, Laelaps sp. A and B of Allred, 1970, and Liponyssoides muris, all of which were elsewhere reported from Rattus spp. in Rangoon. Analysis of variation in abundance by season found no significant differences except for Liponyssoides muris which was most common in the hot dry season, March through May.

In Rangoon, Burma, over half the commensal B. bengalensis taken in live traps were found to be infested with Xenopsylla species fleas. X. astia infestations were twice as common as those of the classic plague vector X. cheopis. In terms of absolute numbers X. astia outnumbered X. cheopis by 10 to 1. X. astia was more commonly found as a monospecific infestation, and X. cheopis was more commonly found mixed with X. astia. The flea indicies were high, with a specific index of 2.4 for X. cheopis and 10.2 for X. astia. The flea indicies and flea sex ratios remained stable across the host population and could not be correlated to changes in the head and body length of the host and were not different on male or female hosts. The evidence of this and other surveys is that X. cheopis is not as well adapted for parasitism on free ranging B. bengalensis as is X. astia.
