The clinical aspects of Mycoplasma pneumoniae infection in 103 children under 12 years admitted to hospital over an eight-year period were reviewed retrospectively. Respiratory illnesses occurred in 87 (85%) cases. The prevalence of lower respiratory tract involvement was similar in both pre-school and school children. Cough was the commonest symptom at all ages. Coryzal symptoms and wheeze were common in pre-school children. Most infants had signs of pharyngitis or otitis media. Non-specific symptoms--fever, lethargy, malaise, anorexia and vomiting--were common accompaniments in children older than one year of age. Non-respiratory illnesses in 16 (15%) patients included gastroenteritis, convulsions, non-specific skin rashes and limb pains. The duration of stay in hospital ranged from two to 30 days (median five days) with apparent clinical recovery and resolution of chest X-ray abnormalities within three months in 78 (76%) patients seen for review.

M. pneumoniae is a common cause of pneumonia. The diagnosis is suspected when the patient presents with symptoms suggesting primary atypical pneumonia including cough, fever, chills, headache, and malaise in association with a segmental or subsegmental pulmonary infiltrate(s), the white blood cell count is normal or only slightly elevated, and the Gram stain of the sputum (if any can be obtained) reveals polymorphonuclear leukocytes and few bacteria. The diagnosis is more difficult when the patient presents with symptoms not suggestive of pneumonia including lethargy, dyspnea, and a 1- to 4-week history of shortness of breath without cough or fever in association with diffuse reticulonodular or interstitial pulmonary infiltrates. The disease in the previously healthy host is usually benign and self-limiting. However, the course is shortened by the administration of tetracycline derivatives or erythromycin. M. pneumoniae pneumonia can occur in association with other diseases including sickle cell anemia, sarcoidosis, systemic lupus erythematosus, Hodgkin's disease, and various other immunodeficiency states. In these patients mycoplasma pneumonia can be very serious. Although there is no pathognomonic clinical or radiographic presentation, careful consideration of epidemiologic, clinical, laboratory, and radiographic data are usually sufficient to suggest the diagnosis in most patients.

Mycoplasma pneumonia usually follows a benign course and the patient does not require hospitalization. The present report summarizes the feature of eight children admitted for a moderately severe pneumonia during an epidemic of Mycoplasma pneumoniae in Victoria. All children were previously healthy. The usual presenting symptoms included cough, fever, lethargy, and weight loss. All children had moderately severe respiratory distress and physical signs in the chest consistent with extensive parenchymal involvement. Half of this group had radiological evidence of a small pleural effusion. Complement fixation titres for Mycoplasma pneumoniae in paired samples confirmed the diagnosis. Clinical and radiological resolution was complete after one to three months. It is suggested that severe mycoplasma pneumonia may be more common than previously appreciated.

Case records of 43 horses with pleural effusion associated with acute pleuropneumonia, chronic pleuropneumonia, or pleuritis secondary to a penetrating thoracic wound were reviewed to determine the predisposing factors, diagnosis, and treatment of this condition. Acute pleuropneumonia was diagnosed in 36 horses, the majority of which were Thoroughbreds (89%). Of 22 (61%) horses that were in race training at the onset of illness, 11 (31%) had been recently transported a long distance and 4 (11%) had evidence of exercise-induced pulmonary hemorrhage. Physical examination findings and hematologic data were nonspecific. The most consistent abnormality was hyperfibrino-genemia. Affected horses were treated with antibiotics, thoracic drainage, nonsteroidal anti-inflammatory drugs, and supportive care. Twenty-two (61%) horses were discharged from the hospital, with the mean duration of hospitalization for those discharged being 23 days. Nine (25%) horses were euthanatized and 5 (14%) died. Bacterial culturing of thoracic fluid resulted in growth in 30 of the 36 (83%) horses. The finding of anaerobic bacteria in thoracic fluid was not associated with a lower survival rate (62%) than the overall survival rate (61%). Four horses with chronic pleuropneumonia had a history of lethargy and inappetence for > 2 weeks. Actinobacillus equuli was isolated, either alone or in combination with other bacteria, from thoracic fluid of these 4 horses. Each horse was treated with broad spectrum antibiotics and made a rapid recovery. Three horses with acute pleuritis secondary to penetrating thoracic wounds also had nonspecific clinical signs, apart from the wound and a large volume of pleural effusion. Bacteriologic isolates from these horses differed slightly from those of horses with acute pleuropneumonia.

The prophylactic effect of in-feed medication of conventional pigs with sulphadimethoxine (SDM), sulphamethoxazole (SMX), and trimethoprim (TMP) was tested by using an Actinobacillus pleuropneumoniae infection model. In each of five experiments, six pigs were given medicated feed twice daily and three pigs received antibiotic-free feed and served as positive (unmedicated, infected) controls. The following drugs or drug combinations were tested (in mg per kg feed): 500 SDM + 100 TMP, 500 SMX + 100 TMP, 125 SMX + 25 TMP, 125 SMX (alone) and 25 TMP (alone). After six days of feed medication, all animals were endobronchially inoculated with A. pleuropneumoniae in a dose of 1-3.10(4) colony-forming units (CFU). The response to the challenge in all control pigs was characterized by fever, lethargy, anorexia, reduced water consumption, and laboured breathing. At autopsy all controls manifested a fibrinous haemorrhagic pleuropneumonia. In-feed medication with 500 SDM + 100 TMP, 500 SMX + 100 TMP as well as 125 SMX + 25 TMP resulted in an effective protection against the challenge in all treated animals. After consumption of feed medicated with 125 mg per kg SMX or 25 mg per kg TMP, pleuropneumonia was evident in all challenged pigs. The results of this study indicate an in vivo potentiation of SMX and TMP in pigs against this respiratory tract pathogen.

Nine of 74 American alligators (Alligator mississippiensis) from a captive Florida herd of 3-4-m-long, 200-350-kg, adult males greater than 30 yr of age died within a 10-day period during 1995. Nonspecific clinical signs included anorexia, lethargy, muscle weakness, paraparesis, bilateral white ocular discharge, and various degrees of periocular, facial, cervical, and limb edema. Pneumonia, pericarditis, and arthritis were found on postmortem evaluation of the spontaneously dead and euthanatized alligators. Rapidly growing mycoplasmas were identified by culture, and mycoplasma nucleotide sequences were identified by polymerase chain reaction testing of fresh lung and synovial fluid from an affected alligator. Culture of banked frozen lung from necropsy specimens and fresh lung and fresh synovial fluid from newly affected alligators confirmed the presence of a new mycoplasma species in seven of eight individuals. Oxytetracycline was administered, but related deaths continued for 6 mo until only 14 of the initial alligators remained. An enzyme-linked immunosorbent assay to detect antibody was developed, and the organism was transmitted experimentally to naive juvenile alligators, although the source of the organism, Mycoplasma sp. (ATCC 700619), has not been identified. The alligator isolate is a novel species in the mycoplasma family because its nucleotide sequence does not match those of over 75 characterized mycoplasma species. Such factors as population density, animal age, and mycoplasmal virulence likely contributed to the course of disease.

A recently described mycoplasma, Mycoplasma alligatoris, was isolated from dead American alligators (Alligator mississippiensis) that had demonstrated clinical signs of lethargy, anorexia, bilateral ocular discharge, edema. paraparesis, and polyarthritis. The in vitro minimum inhibitory concentration for nine antibacterial agents was determined through serial dilution in broth and plate culture for M. alligatoris isolates. The inhibitory concentration obtained for doxycycline, enrofloxacin, sarafloxacin, oxytetracycline, tilmicosin, and tylosin (< 1 microg/ml) was lower than that of clindamycin (1-8 microg/ml), chloramphenicol (8-16 microg/ml), and erythromycin (32-138 microg/ml).

A 7-year-old Thoroughbred gelding was admitted to Equine Hospital, Korea Racing Association for evaluation and treatment of colic. Based on the size and duration of the large colonic and cecal impaction, a routine ventral midline celiotomy and large colon enterotomy were performed to relieve the impaction. Six days following surgery the gelding exhibited signs of lethargy, fever, inappetence and diarrhea. Eleven days following surgery, the jugular veins showed a marked thrombophlebitis. On the sixteenth day of hospitalization the gelding died suddenly. Upon physical examination, the horse was febrile, tachycardic and tachypnoeic. Thoracic excursion appeared to be increased; however, no abnormal lung sounds were detected. No cough or nasal discharge was present. Hematology revealed neutrophilic leukocytosis. Serum biochemistry was normal but plasma fibrinogen increased. In necropsy, fibrinopurulent fluid was present in the thoracic cavity. There were firm adhesions between visceral pleura and thoracic wall. White, mixed and red thrombi were formed in both jugular veins from the insertion point of IV catheter. Histopathological examination showed fibrinopurulent inflammation and vascular thrombosis in the lung. The pleura showed edematous thickening and severe congestion. The clinicopathological and pathological findings suggest that septic thrombi associated with septic thrombophlebitis metastasized into the pulmonary circulation and were entrapped in the pulmonary parenchyma and provoked pleuropneumonia.

The objectives of this study were to investigate the interactions between Mycoplasma hyopneumoniae and porcine circovirus type 2 (PCV2) and to establish a model for studying the pathogenesis of and testing intervention strategies for the control of PCV2-associated porcine respiratory disease complex (PRDC). Sixty-seven pigs were randomly assigned to four groups. Group 1 (n=17) pigs served as controls, group 2 (n=17) pigs were inoculated with M. hyopneumoniae, group 3 (n=17) pigs were dual infected with M. hyopneumoniae and PCV2, and group 4 (n=16) pigs were inoculated with PCV2. Pigs were inoculated intratracheally with M. hyopneumoniae at 4 weeks of age followed by intranasal inoculation with PCV2 at 6 weeks of age. Dual-infected pigs had moderate dyspnea, lethargy, and reduced weight gain. The overall severity of macroscopic lung lesions, PCV2-associated microscopic lesions in lung and lymphoid tissues, and the amount of PCV2-antigen associated with these lesions were significantly (P <0.05) higher in dual-infected pigs compared with all other groups. Four of 17 (23.5%) dual-infected pigs had decreased growth rate and severe lymphoid depletion and granulomatous lymphadenitis associated with high amounts of PCV2-antigen consistent with postweaning multisystemic wasting syndrome (PMWS). PCV2-antigen in lung tissue was most often associated with M. hyopneumoniae-induced peribronchial lymphoid hyperplasia, suggesting that this is an important site for PCV2 replication in the lung. This study indicates that M. hyopneumoniae potentiates the severity of PCV2-associated lung and lymphoid lesions, increases the amount and prolongs the presence of PCV2-antigen, and increases the incidence of PMWS in pigs.

Babesia felis, originally identified in wild cats in the Sudan, was subsequently found to cause clinical disease in domestic cats. Although babesiosis in domestic cats has been reported sporadically from various countries, as a significant disease it appears to be a distinctly South African phenomenon. Apart from an inland focus, feline babesiosis is reported regularly only from coastal regions. The infection is assumed to be tick-borne, but the vector has not been identified. Feline babesiosis tends to be an afebrile, chronic, low-grade disease. The most frequently reported complaints by owners are anorexia and lethargy. The main clinical findings are anemia, depression, and occasionally icterus. Concurrent infections (e.g., Mycoplasma haemofelis, FeLV, FIV) may contribute to the clinical picture. Laboratory findings commonly include regenerative anemia, elevation of alanine transaminase (but not alkaline phosphatase) and total bilirubin concentrations, and a variety of electrolyte disturbances. Secondary immune-mediated hemolytic anemia can be seen occasionally. Drugs effective against other Babesia species give variable and questionable results. The drug of choice is primaquine phosphate, which effects a clinical cure but does not sterilize the infection. Repeated or chronic therapy may be required.
