A Novel Presentation of in Young Broilers.

Necrotic enteritis (NE) is an important intestinal disease of commercial poultry associated with poor performance, high mortality, and significant economic loss. In this case report, a novel presentation of NE is described in young broilers. Initially, affected farms presented with a moderate increase in mortality at or before 19 days of age.

Testicular Atrophy and Epididymitis-Orchitis Associated with Infectious Bronchitis Virus in Broiler Breeder Roosters.

Infectious bronchitis is a respiratory disease of chickens caused by a gammacoronavirus named infectious bronchitis virus (IBV). In addition to affecting the respiratory tract, IBV may also induce urogenital infections, leading to nephropathogenic disease, false layer syndrome in laying hens, and epididymal lithiasis and epididymitis in males. Here, we report a case of decreased reproductive efficiency due to male infertility in 33- to 38-wk-old broiler breeders.

A Field Study of Histologic and Bacteriologic Characterization of Femoral Head Separation and Femoral Head Necrosis.

Histologic and bacteriologic features for groups of average 31-day-old broilers displaying three gross categories of femoral head alterations were documented. Categories included simple femoral head separation (FHS), femoral head transitional changes (FHT), and femoral head necrosis (FHN). Groups with grossly normal (NORM) femoral heads and cull birds with FHN and having gross signs of sepsis (Cull-FHN) were also included in the study.

High incidence of glomerulonephritis associated with inclusion body hepatitis in broiler chickens: routine histopathology and histomorphometric studies.

During the routine histologic evaluation of an outbreak of inclusion body hepatitis (IBH) in Mississippi broilers, a high incidence of renal enlargement and glomerulonephropathy was observed in the birds presenting classic hepatic pathology. Characteristic intranuclear adenoviral inclusion bodies were demonstrated in the livers of these birds, and fowl adenovirus was identified by viral isolation and by PCR. The glomerular lesions were consistent with proliferative or membranoproliferative forms of glomerulonephritis.

Epidemiology and effect on production parameters of an outbreak of inclusion body hepatitis in broilers.

In 2007, an inclusion body hepatitis (IBH) outbreak affected several broiler farms in Mississippi. Results of logistic regression analyses showed significant associations between IBH occurrence and high enzyme-linked immunosorbent assay geometric mean titers for infectious bursal disease virus. However, there was no association between IBH occurrence and chicken infectious anemia virus status.
