We investigated the infection rate of gastrointestinal (GI) parasite eggs and premature stages from different wild animals and birds in Bangabandhu Sheikh Mujib Safari Park, Dulahazra, Cox’s Bazar.  A total of 56 fecal samples were collected from 24 species during July to November 2012 using modified Stoll’s ova dilution technique.  Coprology analysis revealed that the overall rate of parasitic infection was 78.6%, of which 51.8% were helminths and 35.7% protozoa.  The identified parasites were Paramphistomum spp. (7.1%), Fasciola spp. (5.4%), strongyles (26.8%), Ascaris spp. (3.6%), Strongyloides spp. (7.1%), Dictyocaulus spp. (5.4%), Trichuris spp. (3.6%), Capillaria spp. (5.4%), Heterakis spp. (3.6%), and Balantidium coli (35.7%).  Mixed infection (21.4%) was observed in nine animals, including co-infection with Balantidium coli and strongyles in Tiger Panthera tigris, Sambar Deer Rusa unicolor and Pig-tailed Macaque Macaca nemestrina, Strongyloides spp., Trichuris spp. and larvae of Dictyocaulus spp. in Capped Langur Trachypithecus pileatus, Balantidium coli and Capillaria spp. in Clouded Leopard Neofelis nebulosa, Fasciola spp. and Balantidium coli in Spotted Deer Axis axis, Ascaris spp. and strongyles in African Elephant Loxodonta africana, Strongyloides spp. and Heterakis spp. in Peafowl Pavo cristatus and Heterakis spp. and strongyles co-infection in Great Pied Hornbill Buceros bicornis.  It is concluded that GI parasites were prevalent in this safari park.  Further epidemiological investigation is necessary for controlling parasitic infection.

Black tiger shrimp (Penaeus monodon Fabricius 1798) cultured in Bangladesh was investigated for the presence of microsporidian parasite. Histological section of hepatopancreas showed a large number of microsporidian spores under light microscopy. Spores under scanning electron microscope appeared oval shapes. Histology of infected shrimps showed severe degeneration of hepatopancreatic tubules. Early and late stage of microsporidian parasites in hepatopancreatic tubules were also observed. DNA extracted from the hepatopancreas of shrimps were subjected to PCR amplification using primers targeting microsporidian SSU rRNA gene. The PCR amplified an expected product of ~328 bp and the sequences showed 81 -82% identity with the Paranucleospora theridion reported from western Norway in 2008. Further screening of field samples was carried out using EHP-specific primers. DNA extracted from ten hepatopancreas samples of P. monodon were tested and none found to be positive for EHP (Enterocytozoon hepatopenaei). This is the first report for the identification of microsporidian parasites in cultured shrimp along the south-west region of Bangladesh.

Background: Elective or emergency caesarean sections are routinely done under spinal anaesthesia (SA) with bolus dose of local anaesthetic drugs. Objective: To compared fractionated dose with bolus dose in SA for haemodynamic stability and duration of analgesia in patients undergoing elective lower segment caesarean section (LSCS). Methods: The present study was carried out in the Department of Anaesthesiology, Ad-din Akij Medical College Hospital, Khulna from January 2018 to December 2018 on sixty female patients (thirty in each group) of the American Society of Anesthesiologists physical status I–III, age from 18 to 40 years, height from 140 to 180 cm, singleton pregnancies scheduled for elective LSCS under SA. Patients with pre-existing diseases or pregnancy-induced hypertension, cardiovascular or cerebrovascular disease, any contraindication to SA, those weighing <50 kg or >110 kg and those taller than 180 cm or shorter than 140 cm and severely altered mental status, spine deformities or history of laminectomy were excluded from the study. Results: The mean duration of analgesia was statistically significant (p<0.05) between two groups. Mean pulse rate- after 5 min, after 10 min, after 15 min, after 30 min, after 45 min and after 60 min were significantly (p<0.05) higher in group F than group B. Mean arterial pressure- before given study drug, after 0 min, after 5 min, after 10 min, after 15 min, after 30 min, after 45 min and after 60 min were not significantly (p>0.05) between two group. 14 patients (46.7%) in group B and 5 patients (16.7%) in group F required vasopressor. The difference was significant (p<0.05) between two groups. Conclusion: Separation process in which a certain quantity of a mixture dose of SA provides better haemodynamic stability and longer period of analgesia compare to bolus dose in patients undergoing elective caesarean section.
