The pathological changes in the proventriculi of fowls given monospecific experimental infection with Acuaria spiralis were characterized in the initial stages by an acute inflammation due to the migration of 3rd and 4th stage larvae. There was a severe non-keratinizing squamous cell metaplasia of the lining epithelium with pronounced granulocytic infiltration at 4-8 days post-infection. Multiple lymphoid nodules were evident in the lamina propria from 12 days post-infection. As the disease progressed there was extensive fibroplasia in the organ. By 50-100 days post-infection pedunculated fibro-adenamatoid growths developed in the mucosa obliterating the entire lumen of the organ. A mortality rate of 29.16% of chicks (maximum on the 3rd week post-infection) was observed.

BACKGROUND
Infectious bronchitis virus primarily induces a disease of the respiratory system, different IBV strains may show variable tissue tropisms and also affect the oviduct and the kidneys. Proventriculitis was also associated with some new IBV strains. Aim of this study was to investigate by immunohistochemistry (IHC) the tissue tropism of avian infectious bronchitis virus (IBV) strain M41 in experimentally infected chicken embryos.
RESULTS
To this end chicken embryos were inoculated in the allantoic sac with 10(3) EID(50) of IBV M41 at 10 days of age. At 48, 72, and 120 h postinoculation (PI), embryos and chorioallantoic membranes (CAM) were sampled, fixed, and paraffin-wax embedded. Allantoic fluid was also collected and titrated in chicken embryo kidney cells (CEK). The sensitivity of IHC in detecting IBV antigens in the CAM of inoculated eggs matched the virus reisolation and detection in CEK. Using IHC, antigens of IBV were detected in nasal epithelium, trachea, lung, spleen, myocardial vasculature, liver, gastrointestinal tract, kidney, skin, sclera of the eye, spinal cord, as well as in brain neurons of the inoculated embryos. These results were consistent with virus isolation and denote the wide tissue tropism of IBV M41 in the chicken embryo. Most importantly, we found infection of vasculature and smooth muscle of the proventriculus which has not seen before with IBV strain M41.
CONCLUSION
IHC can be an additional useful tool for diagnosis of IBV infection in chickens and allows further studies to foster a deeper understanding of the pathogenesis of infections with IBV strains of different virulence. Moreover, these results underline that embryonic tissues in addition to CAM could be also used as possible source to generate IBV antigens for diagnostic purposes.

Co-occurrence of Pectinospirura argentata Wehr, 1933, Skrjabinoclava andersoni n. sp. and larvae (Nematoda: Acuariidae) in the proventriculus of Larus dominicanus Lichtenstein (Aves: Laridae), with notes on their attachment.
Pectinospirura argentata Wehr, 1933, Skrjabinoclava andersoni n. sp. and acuariid larvae, collected from the proventriculus of the kelp gull Larus dominicanus from coastal Buenos Aires, Argentina, are described. This is the first record of the genus Pectinospirura Wehr, 1933 from South America and from the kelp gull. The measurements of both sexes are given because there are some differences with previously described specimens of P. argentata; the male is smaller with smaller spicules and the female is larger with smaller eggs. Skrjabinoclava andersoni n. sp. can be distinguished for all other species in the genus by the morphology of both spicules and by the cuticle which is not inflated anteriorly. This genus is reported for the first time in the kelp gull and from Argentina.

Three pepsinogens were isolated and purified from the proventriculus of the ostrich Struthio camelus, by a combination of chromatography steps on DEAE-cellulose, Sephadex G-100 and Hydroxylapatite. The purified pepsinogens manifested peptic activity towards haemoglobin as substrate after activation, but resembled chicken pepsinogens in that they appeared to lose their potential peptic activities during storage. All three pepsinogens contained glycine as N-terminal amino acid, but differed in their overall amino acid compositions. The pH and temperature optima of the activated pepsinogens were determined, as well as their molecular weights.

The topographical distribution of the enteric ganglia has been investigated in the proventriculus of the duck using protein gene product 9.5 (PGP 9.5) immunohistochemistry. Myenteric ganglia were usually located between the outer longitudinal and the inner circular muscle layer. Submucous ganglia were sparsely distributed and seemed to be substituted by ganglia located in the tunica mucosa. The neurochemical profile of proventricular ganglion cells was also investigated using nicotinamide adenine dinucleotide phosphate reduced-diaphorase (NADPH-d)-histochemistry and pituitary adenylate cyclase activating peptide (PACAP)/galanin (Gal) double-labelling immunohistochemistry. The majority of mucosal ganglion cells were shown to contain the NADPH-d enzyme and both the investigated peptides. These findings provide evidence for the presence of a mucosal ganglionated plexus in the glandular stomach of birds. Moreover, the neurochemical characteristics of this plexus suggest that it plays an important role in regulating several mucosal functions and, in particular, the production and the composition of the gastric juice.

The effects of dietary fumonisin B1 were evaluated in young broiler chicks. The experimental design consisted of 5 treatments each with 9 randomly allotted male broiler chicks. Day-old chicks were fed diets containing 0 (feed control), 100, 200, 300, or 400 mg fumonisin B1/kg feed for 21 days. Response variables measured were chick performance, organ weights, serum biochemistry, and histologic parameters. Body weights and average daily gain dramatically decreased with increasing dietary fumonisin B1, and liver, proventriculus, and gizzard weights increased. Diarrhea, thymic cortical atrophy, multifocal hepatic necrosis, biliary hyperplasia, and rickets were present in chicks fed diets containing fumonisin B1. Serum calcium, cholesterol, and aspartate aminotransferase levels all increased at higher fumonisin dietary levels. Results indicate that fumonisin, from Fusarium moniliforme culture material, is toxic in young chicks.
