To determine the epidemiology of outbreaks of avian influenza A virus (subtypes H5N1, H9N2) in chickens in Bangladesh, we conducted surveys and examined virus isolates. The outbreak began in backyard chickens. Probable sources of infection included egg trays and vehicles from local live bird markets...

To evaluate risk factors for infection with highly pathogenic avian influenza A virus (H5N1) in backyard chickens in Bangladesh, we conducted a matched case-control study. We enrolled 25 case farms (cases March-November 2007) and 75 control farms (June-November 2007). We used a questionnaire to coll...

BACKGROUND: Eucalyptus pauciflora (the snow gum) is a long-lived tree with high economic and ecological importance. Currently, little genomic information for E. pauciflora is available. Here, we sequentially assemble the genome of Eucalyptus pauciflora with different methods, and combine multiple ex...

A matched case-control study was carried out to identify risk factors for highly pathogenic avian influenza A virus (subtype H5N1) infection in commercial chickens in Bangladesh. A total of 33 commercial farms diagnosed with H5N1 before September 9, 2007, were enrolled as cases, and 99 geographicall...

Siadenoviruses have been detected in wild and captive birds worldwide. Only nine siadenoviruses have been fully sequenced; however, partial sequences for 30 others, many of these from wild Australian birds, are also described. Some siadenoviruses, e.g., the turkey siadenovirus A, can cause disease; ...

Small-scale commercial chicken farms (FAO-defined system 3) with poor biosecurity predominate in developing countries including Bangladesh. By enroling fifteen highly pathogenic avian influenza (HPAI) cases occurring in such farms - (February - April 2008) and 45 control farms (March-May 2008) with ...

Goat farming in Bangladesh is primarily centred on indigenous Black Bengal goat, a highly prolific breed. Searching for genetic markers associated with prolificacy in this breed is vital for the country’s goat breeding industry. However, there are no reports on polymorphisms associated with the fert...

The aim of this longitudinal study was to verify the prevalence and antibiotic susceptibility pattern of Escherichia coli (E. coli) in cattle reared on Bathan and intensive farming system in Bangladesh. Fecal materials originated from recto anal junction (RAJ) of 100 cattle used for primary screenin...

Abstract The events surrounding the 1947 partition and the attack on Sikhs in the Golden Temple and Delhi continue to affect Sikhs today. Memory of the specifics and related issues plays a major role in politics both in India and within the diaspora. This paper explores the literature on the events ...

This study was conducted to establish the normal dimensions of the different segments of the female reproductive tract of the Black Bengal goats. The reproductive tracts of 56 adult non-gravid, female Black Bengal goat were collected and biometric parameters of different segments of the female repro...

A retrospective study was performed to assess the mortality rates and clinical signs in commercial and backyard chickens naturally infected with the highly pathogenic avian influenza (HPAI) H5N1 virus in Bangladesh. All of the 33 commercial and 25 backyard farms, recorded during the first wave of HP...

vertical transmission. In the long term, such co-propagation can lead to the evolution of specialized microbiomes and functional interdependencies with the host. However, microbiomes are vulnerable to environmental stressors, particularly anthropogenic disturbance such as antibiotics, resulting in d...

BACKGROUND AND AIM: (STEC) has emerged as significant foodborne pathogens. Ruminants are the primary reservoir of the zoonotic STEC. In Bangladesh, previous studies reported the presence of STEC in cattle, goat, and sheep; however, there is little information about STEC carriage by buffaloes. This s...

Polymorphisms in growth differentiation factor 9 (GDF9) and bone morphogenetic protein 15 (BMP15) genes have been found to be associated with litter size in goats across the globe. Our previous study detected single-nucleotide polymorphisms (SNPs) in GDF9 and BMP15 genes associated with litter size ...

A cross-sectional survey was carried out in Bangladesh with the sampling of 514 Black Bengal goats on smallholdings to determine the presence of sorbitol non-fermenting (SNF) Shiga toxin-producing E. coli (STEC). Swab samples collected from the recto-anal junction were plated onto cefixime and potas...

BACKGROUND & OBJECTIVES: Wuchereria bancrofti has shown nocturnal periodicity in India and other endemic countries of the world except pacific regions where non-periodic or diurnal sub-periodic forms have been reported. Presence of sub-periodic form of W. bancrofti in Andaman and Nicobar Islands, In...

Abstract Background Shiga toxin‐producing Escherichia coli (STEC) are zoonotic foodborne pathogens and a significant concern with the emergence of antibiotic resistance. Close human contact might have a higher chance of being transmitted to humans from sheep if the sheep population is a potential re...

The study was conducted to estimate the genetic parameters of Holstein crossbred dairy cows in Chittagong, Bangladesh. Study population consisted of animals from three genetic backgrounds: i) 50% Holstein × 50% Local (H × L); ii) 50% Holstein × 50% Shahiwal (H × SL); and iii) 25% Holstein × 25% Shah...
