This study was planned to determine the efficacy of doxycycline and oxytetracycline in the treatment of feline Mycoplasma spp. infections and to analyze risk factors as well as clinical and haematological findings. Cats accepted to the clinic with complaints such as weakness, loss of appetite and fever were routinely examined. Clinical history of animal was demanded from the owner. An interview and a short questionnaire were conducted to owner to evaluate the risk factors associated with possible Mycoplasma status of animal. During the interview, the age, sex, breed, housing, flea infestation, worm control, external parasite control, other accompanying infections and vaccination status of cats were asked and the data recorded. Peripheral blood smears were stained with the DIFF-QUICK. Fifty positive cats were included in the study, 16 of which were treated with doxycycline (orally, 5 mg/kg twice a day) while other 34 with oxytetracycline (intramuscular injection, 10 mg/kg once a day). It was determined that all (100%) cats with Mycoplasma spp. infection had a flea infestation. Majority of cats (94%) did not receive the regular antiparasitic application and only 6 (12%) of them had complete vaccinations. Mycoplasma spp. infection was associated with younger age and outdoor access. Among the feline breed, striped cat (74%) was more prone to infection. The most common clinical signs encountered in cats were weakness (94%) and anorexia (84%). Haematological parameters revealed thrombocytopenia (86%), and anaemia (40%) in infected cats. At the end of the treatment, recovery rates for doxycycline and oxytetracycline groups were 87.5% and 67.6%, respectively. General status of these cats indicated significant improvement on the 4th day of treatment, and clinical symptoms are restored on the th day. Mycoplasmosis is an important infection for cats having anaemia, thrombocytopenia and leukocytosis. Flea infestations are risk factor for contamination of the disease. Based on our results, we recommend doxycycline treatment (5 mg/kg) for up to 21 days for elimination of Mycoplasma spp. in the blood of infected cats.
Fleas are the common cause of skin disorders in cats. They are well-known for transmitting various pathogens to both cats and humans. Accordingly, this study was conducted to gain insights on the risk factors associated with flea infestation on cats. Flea combing conducted on 426 cats from four distinct regions in Peninsular Malaysia revealed a relatively high rate of flea infestation on 306 cats (71.83%). A total of 651 fleas were collected, all of them were identified as Ctenocephalides felis with the total intensity of 2.13 and abundance of 1.53. The sex ratio of fleas was female-biased at 2.5:1 (♀=464, ♂=187). Statistical analysis of the data revealed that flea infestation was significantly (P<0.05) associated with several risk factors including region, age, weight, status (stray, sheltered, pet), body condition, and hair length. Higher flea prevalence was also observed in female cats (77.99%), big-sized cats (91.76%), stray cats (84.94%), cats with clean body condition (73.35%), and cats with long hairs (78.38%) as compared to their contemporaries within the same comparison variables. The high infestation of fleas in this study is indicative of cats as a flea reservoir particularly C. felis. Thus the findings of this study and the knowledge gained on the risk factors can be used to develop and improve control measures and management of flea infestations.
Cat flea bite in humans results in extremely pruritic skin lesions. It has been reported to occur among those living in domiciliary accommodation. However, nosocomial infestation with cat flea has not been reported. We hereby report a case of nosocomial infestation of cat flea in a hospital facility. Identification of the parasite, its appropriate eradication, and adequate medical management of the patients resulted in a satisfactory outcome.
This paper reports six male undergraduate students living at a local university hostel who were infested with cat fleas (Siphonaptera: Pulicidae: Ctenocephalides felis felis) in February 2009. All of them suffered from maculopapular rashes and severe pruritus after the bites. Investigation revealed the presence of a stray cat in the hostel building; five of the students had a history of contact with the cat. Six cat fleas were collected at the hostel and identified as C. felis felis. Most of the students were not aware of this infestation and did not seek medical treatment.
Stray cats collected from Georgetown, Penang from 2008 to 2010 were screened for ectoparasites via fine-tooth combing. Two cats from a total 102 examined were infested with the dog louse, Heterodoxus spiniger. Both cats, a juvenile male and female were found in close contact with each other prior to capture. The number of lice ranged from 5 and 14 in the male and female cat respectively. Other ectoparasites recovered included the common cat flea, Ctenocephalides felis, one louse species Felicola subrostratus, one tick species Haemaphysalis bispinosa and one mite species of Listrophoridae. The present study reports for the first time the finding of H. spiniger on cats from peninsular Malaysia.
Lagaropsylla signata (Wahlgren, 1903), previously known only from the Island of Java, Indonesia is redescribed and reported for the first time in Deer Cave, Gunung Mulu National Park, Sarawak, Malaysia (west coast of Borneo). Many were found clinging to the earwig Arixenia esau Jordan, 1909. A similar account of a phoretic flea (Lagaropsylla turba Smit, 1958) on the same species of cave-dwelling earwig has been reported in peninsular Malaysia in a well-documented association with the hairless naked bulldog bat, Cheiromeles torquatus Horsfield, 1824. The association of Lagaropsylla signata with Arixenia esau is parallel to the evolution and co-existence with bats in Deer Cave just as in the case of Lagaropsylla turba, Arixenia esau, and Cheiromeles torquatus. The evidence suggests that Lagaropsylla turba and Lagaropsylla signata are obligate phoretic parasites whose survival depends on Arixenia esau to access a bat host. Arixenia esau is reported for the first time in Deer Cave and the occurrence of Lagaropsylla signata on the island of Borneo represented a new record, previously being found only on the island of Java. Images of Lagaropsylla signata attached to Arixenia esau are provided. Xeniaria jacobsoni (Burr, 1912), often associated with Arixenia esau in other geographical areas, was not present in the material examined from Deer Cave. The natural history of the earwig genera Arixenia Jordan, 1909 and Xeniaria Maa, 1974 are discussed and summarized relative to their associations with phoretic fleas and their bat hosts.
Fleas of the genus Ctenocephalides serve as vectors for a number of rickettsial zoonoses, including Rickettsia felis. There are currently no published reports of the presence and distribution of R. felis in India, however, the ubiquitous distribution of its vector Ctenocephalides felis, makes it possible that the pathogen is endemic to the region. This study investigates the occurrence of Rickettsia spp. infection in various subspecies of C. felis infesting dogs from urban areas of Mumbai, Delhi and Rajasthan in India.
Cat fleas were reported to attack human in RPR Batu Kawa, a housing area about 3 km from Kuching town, resulting in an outbreak. A total of 19 people (10 adults and 9 children) were attacked by fleas. They presented with red spots, slightly raised (swollen) and irritation of skin, mostly found on the ankles and legs. The first 4 cases were reported on 29 September 2007 and the last case was on 17 November 2007. The remaining 12 cases which represent the majority of cases reported on 4th October 2007. The study conducted based mainly on field investigation and flea sampling from animals on field at that moment to find out the causes of the disease spread. Flea samples from human and cats were found to be Ctenocephalides felis; which is the most prevalent species in the world. However, no fleas were found on dog, rabbit and rat. This is the first reported case in Kuching; the study was carried out to determine the cause and the epidemiological pattern of the disease. This is important, because cat flea might attack human especially if house owners fail to monitor their pets and practice proper sanitation method to avoid the presence of cat flea larvae at home.
