T HIS study came as an update on communicable parasitic diseases in Iraq. Leishmaniasis, echinococcosis and toxoplasmosis are the most serious communicable ones with important socio-economic problems. The present study was done during 2021. The study area included all Iraqi provinces, the analysis of all cases has been taken into account for more than ten years ago from 2011 to 2020. The distribution of parasitic communicable diseases in that period included four parasitic diseases; toxoplasmosis, leishmaniasis (cutaneous and visceral) and echinococcosis. Communicable parasitic diseases were classified according to provinces, total number of echinococcosis, toxoplasmosis, cutaneous leishmaniasis (CL) and visceral leishmaniasis (VL) recorded 6364, 7097, 89359 and 4453, respectively, CL ( 89359) was the highest communicable disease and the lowest one was VL ( 4453), with significant differences (p<0.05). Echinococcosis (6364) and toxoplasmosis (7097) infections were high without significant differences (P>0.05). Sex distribution of communicable parasitic diseases during 2011-2020 were done. In conclusion, this study indicates that communicable parasitosis is endemic in Iraq, it is more prevalent in rural areas than in urban one; because of the environmental factors which play an important role for increasing the chances of infection.

Fresh water fishes infected with different species of genus Trypanosoma parasite that is similar to that same genus in blood of mammals. Trypanosomiasis or sleeping sickness disease that causes by protozoa flagellate parasites which live inside cell called Trypanosoma. Fish parasites play an important role in regulating the population of their hosts. This study was implemented to verify the infection with Trypanosoma sp. report the cellular intervening through inflammatory response in blood smears of infected fishes. A total of 190 fishes of three species Carasobarbus luteus, Aspius vorax and Liza abu were collected from Al-Hamare and Al-Chibayish marsh south of Iraq. The flagellate parasite Trypanosoma sp. observed in blood of Carasobarbus luteus 41.42% and Aspius vorax 12.28% fishes, while no infection was recorded with Trypanosoma sp. in Liza abu fishes. Prevalence and mean intensity of infection were calculated. The different counts and various types of inflammatory cells were monitored, there are increased in lymphocytes in the infected fishes. Statistically, there are significant differences (p<0.05) among species of infected fish with Trypanosoma sp.
