Neonatal calf diarrhea (NCD) is a common disease affecting the newborn calf and the most
critical period is in the first few days following birth of the calf which is also known as calf
scours. Keeping animals in close confinement where the opportunity for transmission of
causative agents of NCD. The diarrhea and other clinical signs seen with the disease are
caused by the interaction of any of several possible infectious causes. This study was carried
out to isolate, identify and detect the antimicrobial resistant profile of E. coli and Salmonella
from diarrheic calves. A total of one hundred and twenty five fecal specimens were collected
directly from the rectum of diarrheic calves. Of the samples collected 35 (25%) and 11 (8.8%)
was found positive for E. coli and Salmonella respectively. Antimicrobial resistance of these two
isolate was found against Amoxycillin and Tetracycline whereas a high sensitivity was found
towards Ciprofloxacin, Levofloxacillin, Azithromycin and Cefotaxime. Serotyping was done
by using specific antisera to identify variants of the somatic (O) and flagellar (H) antigens.
Cultural and biochemical features also reveal the presence of pathogens in the diarrheic

Schistosomus reflexus (SR) is a congenital birth defect resulting in the malformation of the
whole body. This malformed calves unable to pass through the birth canal and must be
recuperated by caesarean section or fetotomy. This anomaly frequently observed in
ruminants and its characteristic features include spinal inversion, exposure of the abdominal
organs because of a large opening in the ventral abdominal wall, crooked and improperly
positioned limbs adjacent to the skull. Recovery from Schistosomus reflexus (SR) was
carried out by caesarean section and finally the dam was recovered after a continuous
treatment regimen. Investigation from preliminary analysis of related cases depicts that SR
has a genetic aetiology.

A cross-sectional study was conducted to estimate the seroprevalence of Newcastle disease (ND) in backyard chickens at Gazipur distri ct of Bangladesh. Individual serum sample was collected from clinically healthy and non-immunized backyard chickens in four randomly selected upazilla (Sreepur, Kapasia, Kaliakor and Gazipur sadar) under Gazipur district. A total of two hundred samples (50 f rom each upazila) were collected from October 2009 to February 2010. Haemagglutination Inhibition (HI) test was used to determine titer of antibodies against Newcastle disease virus. The mean log2 HI titer to NDV in blood sera of the study population were found 5.54, 6.25, 4.38, 5.32 and seroprevalence were 42.53%, 45.99%, 31.91%, and37.82% in Sreepur, Kapasia, Kaliakor and Gazipur sadar upazilas respectively. The overall antibody titer and seroprevalence of Newcastle disease virus was recorded 5.37 and 39.56% respectively. Further detailed study focusing on Newcastle Disease (ND) virus strain identification and improved management packages to reduce the prevalence of Newcastle Disease (ND) are recommended.

Cattle and other ruminants are natural reservoir of sorbitol non–fermenting shiga toxin
producing Escherichia coli (SNF–STEC), and human beings can be infected through food chain.
Likewise, anti-microbial resistant strain of animal origin may be transmitted to human. The
objectives of this study were to determine the antimicrobial resistance profile of SNF–STEC
isolated from smallholdings cattle. A total of 57 SNF E. coli isolates were tested, of which 88%,
84% and 82% were sensitive to chloramphenicol, gentamicin and ciprofloxacin, respectively. All
the isolates (100%) were resistant to penicillin, whereas, 53% were resistant to trimethoprim–
sulfamethoxazole. Among the 57 SNF E. coli, 28 were shiga toxin producing (carrying stx1 or stx2
gene) which exhibited the highest resistance (57%) against trimethoprim–sulfamethoxazole and
tetracycline, and the lowest (4%) against chloramphenicol. Of the Stx1 genotypic isolates, 60%
and 40% were resistant to trimethoprim–sulfamethoxazole and ampicillin, respectively. On the
other hand, 58% Stx2 genotypic isolates were resistant to tetracycline, whereas 44% both of hly
and eae genotypic isolates were resistant to trimethoprim–sulfamethoxazole. About 60% isolates
carrying all the three STEC virulent genes were resistant to ≥ 2 antimicrobials; among them one
isolate was resistant to six antimicrobials – ceftriaxone, nalidixic acid, ciprofloxacin,
tetracycline, doxycycline and trimethoprim–sulfamethoxazole. Isolates having no virulent gene,
but harboring 54.2 kb sized plasmid were resistant to tetracycline. sulfamethoxazole, ampicillin

Poultry enterprise is an important part of agriculture which is emerging as a strong
agrobased industry in Bangladesh. But this sector is now facing a challenging situation with
recent outbreaks of Avian Influenza (AI), posing a great threat to the growing poultry industry.
Avian influenza is a viral disease that ranges from a mild or even asymptomatic infection to
an acute, fatal disease of chickens, turkey, guinea fowls and migratory water fowls (Clavijo et
al., 2003). Influenza viruses hold generic status in the Family Orthomyxoviridae and are ...
