Dogs, being companion animals serve a variety of economic, social, and cultural purposes.
Among the diseases of dogs, tick-borne protozoa are drawing attention globally for both
human and animals. The aim of this study was to observe the prevalence of tick-borne
protozoan infections as well as some selective hematological parameters of stray dogs in
Dhaka city. A total number of 160 dogs from various places in the study area were selected
randomly and examined for both tick and protozoan infection. Only one species of hard
tick, Rhipicephalus sanguineus was identified where 49 (30.62%) among the study
population were found to be infested with this tick. There were differences in tick burdens
in two seasons with higher infestation levels in Summer (37.50%) followed by Winter
(26.92%). Ticks ranging from 1-16 were removed from dogs where most of the ticks were
collected from the neck and chest region (P <0.001). On the other hand, examinations of
blood smear confirmed three protozoan species (Babesia canis, Babesia gibsoni, and
Hepatozoon spp.) comprising 23.13% of the overall prevalence. Among the protozoan
species, B. canis (11.88%) was the most prevalent protozoa. Subsequently, only 10.81% of
the infected samples showed multiple infections. In both cases, females were more infected
than males. Among the hematological parameters, the RBC counts, Hemoglobin, and PCV
of all infected dogs were significantly lower (P <0.001) compared to the healthy group.
Moreover, the eosinophil of the infected groups showed higher values (11.00 % and
12.70% for protozoa and ticks, respectively) than the normal range indicating parasitic
infections. Therefore, these results suggest the necessity of frequent blood examinations to
enhance animals’ welfare and disease prevention.

Rodents are small mammals which are responsible for the transmission of various deadly
pathogens with zoonotic significance. Blood borne protozoans play a crucial role in this
regards. The present study was performed to determine the prevalence of blood protozoan
parasites of murine rodents in Dhaka city, Bangladesh. A total of 80 rodents with four
rodent species were captured, namely, Rattus norvegicus (n=28), Rattus rattus (n=14),
Bandicota bengalensis (n=30) and Mus musculus (n=8). The rodents were live captured by
using traps from stationary/grocery shops (n=25), local rent houses (n=20), houses from
slum areas (n=15) and fish markets (n=20). The overall prevalence of this study was 50%.
The highest infection rate was found in R. norvegicus (57.14%) followed by B. bengalensis
(53.33%), M. musculus (37.5%) and R. rattus (35.71%). Among the different areas, the
highest prevalence was recorded in slum areas (66.67%) followed by fish markets (50%),
stationary/grocery shops (48%), and local rent houses (40%). Five blood protozoa detected
from the rodents which were Plasmodium spp. (31.25%), Anaplasma marginale (21.25%),
Anaplasma centrale (17.5%), Babesia spp. (10%), and Trypanosoma spp. (3.75%). The
ratio of single and mixed infection was equal (50%). Among the observed blood protozoa,
Trypanosoma spp. and Babesia spp. have a great public health significance. Therefore,
proper attention is recommended to prevent rodent born protozoal zoonosis through
integrated control program.

BASHAR, MUHAMMAD SAIFUL
The gastro-intestinal parasites have always been a problem causing severe
parasitism in game birds where the herds are kept in small-range of area. This
present study was carried out to investigate the gastro intestinal parasites in game
birds in Dhaka and Cumilla city of Bangladesh. The samples were examined by
routine coproscopical methods for the presence of different parasites and oocysts.
The overall prevalence of intestinal parasitic infection was 42% in Bangladesh.
These were documented different gastrointestinal parasites viz, Ascaridia galli,
Heterakis gallinarum, Capillaria sp., Balantidium coli, Eimeria spp., Giardia sp. in
Bangladesh. The highest intestinal parasitic infection (60%) was observed in the
fecal sample collected from Mirpur and Cumilla, followed by Shatfeet (40%),
Katabon (28%) and Mohammadpur (20%) whereas, Ascaridia galli (25%)
Heterakis spp. (8%), Capillaria spp. (8%), Balantidium coli (7%), Eimeria spp.
(8%) and Giardia spp. (2%) were observed. In this investigation, the prevalence of
Ascaridia galli was highest in pigeon (38.71%) followed by parrot (33.33%), dove
(30.77%), quail (25.00%), cockatoo (14.28%), guinea fowl (14.28%) and
budgerigar (13.33%) respectively. The prevalence of Heterakis gallinarum was
16.13%, 15.38% and 14.28% in pigeon, dove and cockatoo respectively. The
prevalence of single infection (23%) was higher than the multiple infection (19%)
of helminthes. Alongside, the prevalence of helminthic infection (29.0%) was
found relatively higher than protozoan infection (24.0%). Therefore, the necessary
steps should be undertaken to control the parasitic infection of pet birds.

ISLAM, SUMAIYA
Poultry is a promising sector in Bangladesh that is growing at a rapid pace and has
grown to become the most important and advanced segment of the livestock sector in
the country. Commercial poultry is infected with a variety of parasites. As a result, the
goal of this research was to look into the population dynamics and morphological
identification of lice in commercial poultry farms of Kishoreganj, Gazipur,
Mymensingh, Tangail and Narsingdi. From November 2020 to April 2021, a total of
245 layer chickens were examined for lice infestation. All the lice were identified
microscopically at the Laboratory of Microbiology and Parasitology. A total of 149
chickens (60.81 %) were infested with lice out of 245 evaluated. During the study,
four lice species were identified: Menacanthus stramineus, Menopon gallinae from
sub-order Amblycera and Gnoiocotes gallinae, Lipeurus caponis from sub-order
Ischinocera. Among them, M. stramineus was the most prevalent species (60.78%)
detected in breast and thigh, followed by M. gallinae (49.02%) in body feathers, L.
caponis (34.90%) in wing feather and G. gallinae (15.03%) in fluff. The highest
prevalence of lice was found in Gazipur (83.93%) followed by Mymensingh
(80.65%), Tangail (72.73%), Narsingdi (66.67%). No lice were detected in
Kishoreganj. This research strongly suggests that poultry lice are a major problem in
commercial poultry chicken. It is indeed necessary to develop an effective control
measure to improve output of commercial poultry in Bangladesh.
