In the present investigation, 30 Long-Evans were examined. Out of 30, 23 rats were infected by helminth parasites, two species of helminth parasites from two taxonomic groups were identified, cestode Hymenolepis nana and nematode Syphacia muris . The prevalence and intensity of parasites were quite different in different groups of helminth parasites in hosts. The prevalence and intensity of infestation of cestodes were 26.67% and 5.57±1.5 while higher of nematodes 66.67% and 60.85±8.1 in the Long-Evans respectively. Hymenolepis nana was found in small intestine and Syphacia muris in all parts of the alimentary tract. The prevalence and intensity of infestation was 36.67% and 5.09±1.6 respectively in small intestine. The prevalence of infestation was similar both in large intestine and caecum (63.33%), and in rectum (63.33%). The intensity of infestation was 24±3.30 and 39.16±4.10 in large intestine and caecum, and in rectum respectively. Key words: Long-Evans; Rattus norvegicus; cestodes; nematodes; prevalence; intensity. DOI: http://dx.doi.org/10.3329/ujzru.v29i1.9464 UJZRU 2010; 29(1): 41-45

Toxicity of pirimiphos-methyl and three essential oils, viz. cardamom [ Elettaria cardamomum (L.) Maton.], cinnamon ( Cinnamomum aromaticum Nees) and clove [ Syzygium aromaticum (L.) Merr. & Perry]; either singly or in mixture in different ratios were investigated on the cowpea weevil, Callosobruchus maculatus (F.) adults, through residual film bioassay. The LD 50 of pirimiphos-methyl was 0.011 μg cm -2 and that of cardamom, cinnamon and clove oils were 20.68, 12.38 and 16.89 μg cm-2 respectively after 24 h post-treatment. Pirimiphos-methyl and tested essential oils were used as mixture of 1:1, 1:2, 1:5, 1:10 and 1:20 and the LD50 values were calculated. All essential oils when combined with pirimiphos-methyl proved to be antagonistic effect against C. maculatus adults except cardamom oil which offered synergistic effect at the 1:20 ratio with pirimiphos-methyl.

A study was conducted to investigate about the prevalence of parasitic diseases in different abattoirs in selective area of Bangladesh such as Comilla and Brahmon Baria districts. Animals were examined for post-mortem defects in different abattoirs of those districts. The study started from February, 2008 to August, 2008. The total examined animals were 3510, among them 1460 cattle, 620 buffaloes, 970 goats and 460 sheep. Age, sex and breed of the examined animals were recorded as far as practicable. The overall prevalence of hydatidosis was highest (26.01%) followed by fascioliasis (20.74%), amphistomiasis (19.62%). The prevalence of above mentioned diseases was higher in older animals. The prevalence of hydatidosis, fascioliasis and amphistomiasis was higher in male in case of cattle and goats. But the prevalence of those diseases was distinctly higher in female animals in case of buffaloes and sheep. The proportional prevalence of different disease conditions in cattle was much higher in Hariana breed than those of local and crossbred cattle.

进行了一项研究，以调查孟加拉国选择性地区(如Comilla和Brahmon Baria地区)不同屠宰场寄生虫病的流行情况。在这些地区的不同屠宰场对动物进行了死后缺陷检查。研究开始于2008年2月至2008年8月。共检测动物3510头，其中牛1460头，水牛620头，山羊970头，绵羊460头。尽可能地记录被检查动物的年龄、性别和品种。总患病率以包虫病最高(26.01%)，其次为片形吸虫病(20.74%)、amphistomasis(19.62%)。上述疾病的患病率在老年动物中较高。牛、山羊中男性包虫病、片吸虫病和amphistomasis患病率较高。但这些疾病在雌性动物中的患病率明显更高，比如水牛和绵羊。哈里亚纳牛中不同疾病状况的比例患病率远高于地方和杂交牛。关键词:屠宰场;人畜共患疾病;寄生虫;家畜。DOI: 10.3329/ujzru.v28i0.5281 Univ. j. zool。Rajshahi university .

A farm economy depends upon a calf per year per cow. Mummified foetus is a reproductive disorder which is responsible for farm economic loss by extending the inter calving period as well as foetal loss. The incidence of mummified foetus in cattle is low and sporadic but the incidence may be higher in some herds (Roberts, 1971). In cattle fetal mummification occurs with an incidence of 0.13-1.8% (Barth, 1986). In Bangladesh there is no accurate account about the incidence of mummified foetus in cow but sporadically mummified foetus occurred throughout the country. Talbot & Hafs (1974) treated the mummified foetus in cow with Prostaglandin F2α. However, such foetus might be treated with intramuscular administration of Stilbestrol, Estradiol, Respositol diethylstilbestrol or manual removal of the persistent corpus luteum (Roberts, 1971). Most mummified foetuses will remain in the uterus until treatment is given to expel them or until their removed by caesarean section (Wenkoff & Manns, 1977). The choice of treatment of this problem is injection of prostaglandin F2α and in failure case caesarean section. There is some evidence of failure to expel mummified foetus by the treatment with prostaglandin F2α. To overcome this type of complication the author has had personal interest to deliver the mummified foetus with cesarean section rather than Prostaglandin F2α injection. Arthur et al. (1996) showed that treatment of mummified foetus with Prostaglandin F2α create some complexicity in cattle like maceration of mummified foetus and packed in the birth canal instead of expelled out. It occurs as a consequence of uterine infection, pyometra, chronic endometritis and finally the animal should therefore be sent for slaughter.

The repellent activity of monoterpenoids viz. eugenol, zimtaldehyde and neem oil against pulse beetle, Callosobruchus maculatus (F.) was investigated. Responses varied significantly with compound, dose and exposure time. The tested components showed highest level of repellency against C. maculatus at a dose of 1 μl. Over 80%, Class V, repellency was achieved after 5 to 60 min. treatment with the components at a dose of 1 μl. The repellent action of zimtaldehyde showed the highest repellency (87.41% at 10 min exposure) status against C. maculatus than neem oil and eugenol, while the lowest (79.46%) was recorded for eugenol at 25 min exposure level.
