Influenza virus surveillance, poultry outbreak investigations and genomic sequencing were assessed to understand the ecology and evolution of low pathogenicity avian influenza (LPAI) A viruses in Bangladesh from 2007 to 2013. We analyzed 506 avian specimens collected from poultry in live bird markets and backyard flocks to identify influenza A viruses.(More)
In Bangladesh, little is known about the genomic composition and antigenicity of highly pathogenic avian influenza A(H5N1) viruses, their geographic distribution, temporal patterns, or gene flow within the avian host population. Forty highly pathogenic avian influenza A(H5N1) viruses isolated from humans and poultry in Bangladesh between 2008 and 2012 were(More)
BACKGROUND Nipah virus (NiV) is an emerging disease that causes severe encephalitis and respiratory illness in humans. Pigs were identified as an intermediate host for NiV transmission in Malaysia. In Bangladesh, NiV has caused recognized human outbreaks since 2001 and three outbreak investigations identified an epidemiological association between close(More)
We investigated unusual crow mortality in Bangladesh during January-February 2011 at two sites. Crows of two species, Corvus splendens and C. macrorhynchos, were found sick and dead during the outbreaks. In selected crow roosts, morbidity was ~1 % and mortality was ~4 % during the investigation. Highly pathogenic avian influenza virus H5N1 clade 2.3.2.1 was(More)
The parasites of genera Haemoproteus, Plasmodium, and Leucocytozoon are well-known avian haematozoa and can cause declined productivity and high mortality in wild birds. The objective of the study was to record the prevalence of haematozoan parasites in a wide range of wetland birds in Bangladesh. Six species of Haemoproteus, seven species of Plasmodium,(More)
We tested 1149 ruminant sera conveniently collected from three districts of Bangladesh to identify the serological evidence of Coxiella burnetii infection in cattle and goats by enzyme-linked immunosorbent assay. We found that 0.7% (8/1149) of ruminants had detectable immunoglobulin G for C. burnetii: 0.65% (4/620) in cattle and 0.76% (4/529) in goats. A(More)
Detection of zoonotic pathogens carried by bats is important both for understanding disease ecology and for developing preventive measures. Pteropus fruit bats have been identified as potential carriers of Salmonella enterica serotype Typhi. A cross-sectional study was conducted to determine the prevalence of Salmonella Typhi and other Salmonella serotypes(More)
Araştırmanın amacı sığırlarda helmintlere karşı uygun enjektabl formülasyonunun belirlenmesidir. Ellialtı adet sığır üç gruba ayrıldı. Birinci grup (n: 27), ikinci grup (n: 16) ve üçüncü grup (n: 14) sırası ile ivermektin+klorsulan, nitroksinil ve her iki ürün birlikte uygulandı. Her üç grupta da ilaçlar ilaçlar Fasciola türlerine karşı %100 etkili bulundu.(More)
Background In March 2011, a multidisciplinary team investigated 2 human cases of highly pathogenic avian influenza A(H5N1) virus infection, detected through population-based active surveillance for influenza in Bangladesh, to assess transmission and contain further spread. Methods We collected clinical and exposure history of the case patients and(More)
Araştırmanın amacı dört antelmentiğin (piperazin sitrat, albendazol, fenbendazol, ivermektin) doğal enfekte ördeklerde etkinliğini belirlemektir. Farklı çiftliklerden elde edilen yirmi ördek temin edilerek dışkıları üç ayrı helmint açısından incelendi. Ördekler dört eşit gruba beş uygulama yapılacak şekilde ayrıldı. Dışkının her gramındaki yumurta oranı(More)
