To study the prevalence of gastrointestinal parasites of deer, 127 fecal samples were collected from Char Kukri Mukri upazilla of Bhola district of Bangladesh during the period from January to May, 2013. Eighty eight samples were found to be infected with gastrointestinal parasites and overall prevalence rate was 69.29%. Fasciola sp. (8.66%), Paramphistomum sp. (20.47%), stomach worm (18.11%), hook worm (20.47%), Strongyloides sp. (1.57%), Oesophagostomum sp. (1.57%), Eimeria sp. (6.30%) and Balantidium coli (1.57%) were found. The overall prevalence of nematode, trematode, protozoan and mixed infection were 29.13%, 25.19%, 5.51% and 9.45% respectively. Seasonal prevalence of gastrointestinal parasites in summer and winter were 70.59% and 66.67% respectively. The range of EPG/CPG/OPG varied from 100 to 300 among the parasites and highest count was found in Paramphistomum sp. (300), hook worm (300) and stomach worm (300). This study provided a first overview on parasites in deer in the vicinity of villages, but to evaluate parasite transmission dynamics much more studies were required on livestock and on wild herbivores.

Ectoparasite infestations have direct and indirect negative impacts on its host. Ectoparasite fauna of pigs of Bangladesh is not well documented. Our objective was to detect the ectoparasite fauna among the pigs in Rangamati district of Bangladesh. We examined, 480 pigs from 104 households by close inspection and detected one species of louse (e.g., Haematopinus suis), three species of ticks (Amblyoma testudinarium, Haemaphysalis bispinosa, and Rhipicephalus sanguineus), and one species of flea (Ctenocephalides canis). Pathology and economic losses due to the detected ectoparasites in Rangamati district need further investigation for the betterment of the local pig industry. Bangladesh J. Agri. 2022, 47(1): 88-94

Mosquitoes are the small insects belonging to the order diptera. They are familiar parasitic vectors of a number of transmissible and life menacing diseases. The study was conducted at the Bangladesh Agricultural University (BAU) campus and its surrounding areas in Mymensingh, Bangladesh from January to June, 2013 detect adult mosquito species and their status. Adult mosquitoes were collected using light traps (LTs), insect collecting nets, and human bait (HB) from households, cattle sheds, rice field, botanical garden, dairy farm and poultry farm and staff residential quarters. A total of 2,750 adult mosquitoes were collected from these places. Ten species of mosquitoes under two genera were identified. Among the two genera Culex (84.3%) was the leading group dominated over Anopheles (15.7%) in all areas. In case of Culex species, the most prevalent mosquito species was the Cx. quinquefasciatus (39%) followed by Cx. fuscocephala (23.7%), Cx. tritaeniorhynchus (15.8%), Cx. gelidus (4.0%), Cx. whitmorei (1.2%), Cx. vishnui (0.3%) and Cx. whitei (0.3%). On the other hand, among Anopheles species, An. bengalensis (11.1%) was found in the highest percentage followed by An. vagus (3.8%) and An. jayporiensis (0.8%). Among the studied areas, the highest prevalence of mosquitoes were collected from cattle sheds (40.7%), followed by households of Balashpur (16.2%), Boyra (14.9%) and Kewatkhali (12.4%). Though Culex species was found as dominant species in all areas, the highest percentage (96.7%) was found in staff residential area in BAU campus, whereas, the highest prevalence of Anopheles species (28.7%) was found in cattle shed. We found that two genera were prevalent together in almost all areas, however, though Culex was the dominant one. In conclusion, our survey provided useful information on the prevalence of mosquito species regarding the distribution and diseases control.Progressive Agriculture 26:60-66, 2015

The prevalence of snail-borne trematodes (SBTs) of cattle and their vector snails in Rajshahi district in Bangladesh were determined. A total of 380 faecal samples of cattle were collected and examined using Modified Stoll’s Ova Counting Technique. Of the smaples examined, 130 (34.2%) animals were found affected with SBTs, and the mean egg per gram of faeces (EPG) was 180.3 ± 0.8. The trematodal infections by Fasciola gigantica (1.1%), different amphistomes (32.9%), and Schistosoma spindale (0.8%) were detected among the infected cattle. The effects of age, sex, breed, and body condition of the cattle on the prevalence of SBTs were determined. The infection rate was higher in young (> 2- 4 years) cattle (46.5%), followed by calves of ≤ 2 years (35.3%), and the lowest in older (> 4 years) cattle (20%). The prevalence of trematode infections was significantly (P<0.0001) higher in females (36.5%) than in male (28.3%) cattle. The prevalence was higher in cattle with poor body condition (48.7%) than in cattle with normal body condition (24.8%). Significantly (P<0.008) higher prevalence of trematode infection was recorded in indigenous cattle (41.2%) than in cross-bred cattle (26.9%). It is suggested that SBT infection is a common problem in cattle in Rajshahi district of Bangladesh. Particular emphasis should be given to proper management and regular deworming, and sustainable control measures should be developed for the prevention of SBT infection in cattle. Bangl. vet. 2021.
