SUMMARY: Dogs are the main transmitter of rabies virus for humans in Sri Lanka. Therefore, updated information on the dog rabies vaccination coverage and dog ecology are essential for launching an effective rabies elimination program in the country.
A descriptive cross sectional study was conducted in 120 clusters. Counts recorded at the vaccination centres were considered as the capture sample. In the recapture sample, data collected on humans and dogs through the questionnaire survey administered on households were considered. Number of dogs vaccinated against rabies and the total number of people in the dog-owning households that attended the vaccination centres were 2508 and 8690
respectively. The household survey of the study included 2207 households, which includes 8650 family members. Among these households, 774 houses had dogs which included 3382 family members.
From the 2933, free-roaming owned dogs and free-roaming dogs with undetermined ownership counted through the transect line, 1413 had been marked in the study areas. Out of 838 owned confined and owned freeroaming dogs found during the questionnaire survey administered on 2207 households, 579 were recorded as recaptured.
The estimated human population of the area surveyed was 34,901. The tabulated ratio of the total dog population in total human was 1:6.7 and owned dog population to human ratio was 1:9.6. The estimated owned dog population was 3630 and the total dog population was 5205. The total dog vaccination coverage is 48% (2508/5205).Owned (confined and free-roaming) dog vaccination coverage achieved was 69%. Vaccination coverage among owned free-roaming dogs was 54% and significantly low (P<0.005), compared to owned confined dogs which was 77% . Majority of the dogs owned were local breeds (90.5%) aged between 1 and 5 years old. Findings revealed that 34% of the owned dogs were allowed to roam freely during the day.
During annual mass vaccination campaigns, there should be a method to include dogs in all three categories i.e. Owned confined, owned free-roaming and dogs with undetermined ownership status. Considering confinement status practiced, allowing dogs to roam freely should be discouraged. This could potentially be acquired through implementing educational programs and new legislations bound with legal means.

SUMMARY: Canine hepatozoonosis caused by H. canis is usually recognized as a mild clinical disease characterized by mild anaemia and lethargy. Complicated clinical manifestations of H. Canis infection have been occasionally observed in dogs. This clinical communication describes acute hepatozoonosis in five dogs characterized by neurological symptoms, ataxia or paresis, emaciation and anaemia.

SUMMARY: Piscine mycobacteriosis is a systemic, chronic, progressive disease in fish caused by the nontuberculous mycobacteria (NTM). It has significant economic and public health impacts on commercial culture of ornamental fish. Clinical manifestation and the pathology of the infection in ornamental fish may vary depending on the species of fish affected and the species of the pathogenic NTM involved. This clinical communication describes mycobacteriosis in two different ornamental species; gold fish (Carassius auratus) and koi carp (Cyprinus carpio).
