Eastern equine encephalomyelitis (EEE) was the cause of heavy mortality in coturnix quail (Coturnix coturnix) reared commercially in South Carolina. The birds showed depression, tremor, and partial paralysis that advanced into complete paralysis, torticollis, and death within a few hours. The only consistent lesion on necropsy was a catarrhal enteritis in the duodenal area. The disease spread rapidly to all pens throughout the two houses on the farm in all birds over 2 weeks old, and mortality ranged from 40 to 90% in the various pens within the house. Total mortality exceeded 90,000 birds. Age groups on the farm ranged from 1 day to 8 weeks, at which time the birds went for slaughter. It appears that the initial infection was spread by cannibalism. EEE was diagnosed by isolating the virus in fertile eggs and suckling mice, with subsequent identification by complement-fixation. This is the first documented case of EEE in coturnix quail.

42 episodes of verified or clinically suspected cytomegalovirus (CMV) infection in 40 bone marrow transplant (BMT) recipients were treated with foscarnet (trisodium phosphonophormate hexahydrate). CMV infection was verified in 31/42 treatment episodes. Symptoms treated were pneumonia (n = 17), pancytopenia with or without fever (n = 12), enteritis (n = 5), fever (n = 4), encephalitis (n = 2), retinitis (n = 1) and hepatitis (n = 1). Foscarnet was given as a continuous intravenous infusion. Side-effects observed were increase in serum creatinine (38%), decrease in serum calcium (19%), increase in serum bilirubin (12%), decrease in hemoglobin concentration (7%), increase in serum calcium (5%), increase in serum transaminase (5%), hypophosphatemia (2%) and tremor (2%). CMV was eradicated from blood and/or urine in 11/25 (44%) of assessable treatment episodes with infection verified by isolation. Overall clinical improvements including eradication of CMV, afebrility and/or improvements in laboratory abnormalities were seen in 14/31 (45%) episodes of verified infection. All 15 patients with CMV interstitial pneumonia (CMV IP) died. We conclude that foscarnet is nephrotoxic but otherwise well tolerated with moderate clinical and virostatic effects on CMV infection. The effect on CMV IP is discouraging.

Among 62 infants admitted to our hospital after an acute and apparently threatening event which according to the parents required active intervention either by tactile stimulation, or shaking or mouth to mouth ventilation were 21 previously preterm babies, 12 of whom with additional perinatal risk factors, and 41 fullterm infants, 3 of them being subsequent siblings of a SIDS victim. More than 80% of the ALTEs occurred during presumed sleep while the remaining 20% were observed during wakefullness, mostly during or shortly after feeding. The majority was said to be found pale or blue, floppy and mostly unreactive. The parents or caretakers, however, were unable to give reliable information concerning the type of breathing i.e. whether the infants were apneic or not. On admission, 71% of the pre- and 63% of the fullterms showed abnormal signs and symptoms. A total of 14 infants had symptoms of respiratory tract infections, involving the lungs in only 6 cases. An other 10 infants developed moderate enteritis after admission only; 8 of them had stool cultures positive for rotavirus antigen. On the basis of the anamnestic and clinical data including the results of the diagnostic work-up in 14 (34%) of the fullterm and 3 (14%) of the preterm infants a so far unrecognized disorder was diagnosed which in many cases gave access to a specific therapy. If the cases of infections - not including those with only mild respiratory tract involvement often found in cases of SIDs or near miss SIDS - are included in this group their number increased to 27 (43,5%).(ABSTRACT TRUNCATED AT 250 WORDS)

The clinical and pathological findings after a natural intra-uterine infection with BVD-virus in a Friesian dairy herd are described. The virological and serological aspects will be discussed in a separate paper (30). In a period of 4 years, 11 calves were born with the following nervous symptoms: more or less serious incoordination, tremor, oscillating nystagmus, and a negative blinking reflex. The pupillary and sucking reflexes were normal. No ocular defects, such as lenticular opacity or retinal atrophy were observed. The first calf was born in 1979. Within 6 months the symptoms disappeared. After a normal conception and pregnancy this animal gave birth to 2 clinically normal calves in 1981 and 1982. The second calf died at the age of 2 months, due to an ulcerating enteritis. In 1980, again 8 calves with the same nervous symptoms were born within a period of 3 months. Two calves died at the age of 3 days and 5 weeks respectively; 2 calves were sold when 10 days and 3 weeks old; one calf did not improve and was necropsied at the age of 17 days. The remaining 3 calves showed only a slight hypermetria when examined after 6 months. At that time nystagmus was only visible with ophthalmoscopy. Two calves were slaughtered when 10 months old. The last one, a bull, proved to be sterile and was necropsied at the age of 1 1/2 year. A calf, born in 1981, recovered within a week and was necropsied at the age of 15 days. The last calf, born in 1982, did not improve at all and was necropsied at the age of 14 days. During these 4 years none of the other animals in the herd showed any symptoms due to an acute or chronic BVD-virus infection. At post mortem examination of 6 animals no macroscopically visible malformations were found. Hypomyelination and abnormal glial cells were evident in 5 cases, especially in the two youngest calves which did not show any improvement. One of them had had an obvious thymic hypoplasia. The calf which recovered within a week showed only very slight changes. In one of the calves slaughtered at 10 months, inflammatory lesions were found in the brain. The diagnosis was confirmed by virological investigations. Clinically as well as pathologically there was a close resemblance to Border disease in lambs and congenital tremor in piglets after prenatal exposure to Hog cholera virus.

The recently described atypical porcine pestivirus (APPV) has been associated with congenital tremor (CT) type A-II in piglets in different countries. Another important neurological pathogen of pigs is porcine teschovirus (PTV), which has been associated with non-suppurative encephalomyelitis in pigs with severe or mild neurological disorders. There have been no reports of APPV and/or PTV coinfection associated with CT or encephalomyelitis in Brazilian pig herds. The aim of this study was to describe the pathological and molecular findings associated with simultaneous infection of APPV and PTV in piglets with clinical manifestations of CT that were derived from a herd with high rates of CT-associated lethality. In 2017, three piglets from the same litter with CT died spontaneously. The principal pathological alterations in all piglets were secondary demyelination and hypomyelination at the cerebellum, brainstem and spinal cord confirmed by histopathology and luxol fast blue-cresyl violet stain. Additional significant pathological findings included multifocal neuronal necrosis, neuronophagia and gliosis found in the cerebral cortex and spinal cord of all piglets, while atrophic enteritis and mesocolonic oedema were observed in some of them. APPV and PTV RNA were detected in the central nervous system of affected piglets, and PTV was also detected in the intestine and faeces. The pathological alterations and molecular findings together suggest a dual infection due to APPV and PTV at this farm. Moreover, the combined effects of these pathogens can be attributed to the elevated piglet mortality, as coinfections involving PTV have a synergistic effect on the affected animals.
